Description

Technical Field

[0001] The present invention relates to a shoe care device capable of easily drying the inside of shoes. Background Art

[0002] Generally, sweat accumulates inside shoes that are worn every day due to prolonged use, causing various bacteria to multiply inside the shoes, thereby generating odor and making it impossible to maintain a clean and hygienic state.

[0003] Furthermore, on rainy days, shoes are soaked by rainwater, which generates moisture and bacteria inside the shoes, potentially causing odor or foot health problems.

[0004] In order to remove moisture and bacteria inside such shoes, washing or natural drying is used. However, the operation of washing or natural drying the shoes is cumbersome and takes a long time, so it is difficult to wear clean shoes every day.

[0005] To address this issue, a prior art (Korean Publication No. 10-2020-0031889) provides a circular, shelf-type shoe drying device. This device comprises an inlet connected to a heater to supply hot air to the interior; a drying chamber with an outlet for exhausting internal air; a rotating duct rotatably mounted on the bottom or top surface of the drying chamber, with multiple distribution holes for distributing the hot air supplied through the inlet; and a shelf pipe, one end of which is connected to the distribution holes of the rotating duct. The shelf pipe protrudes at an upward angle to allow shoes to be inserted downward, and is formed with multiple spray holes to spray the hot air supplied through the distribution holes in all directions.

[0006] However, the prior art has the following problem: since the storage tube portion is always exposed to the outside, when the shoe is stored in or taken out of the shoe care device, the shoe interferes with the storage tube portion.

[0007] Furthermore, the conventional technology has a problem in that, since the placement tube is provided in the shape of a clothes hanger, foreign matter dropped from the shoe located on the upper side falls onto the shoe located on the lower side, thereby contaminating the shoe.

[0008] In addition, the prior art has the following problem: it can only dry shoes that are low in height, such as sports shoes, but cannot dry shoes that are higher than sports shoes, such as boots. Therefore, it is necessary to improve it.

[0009] The background technology of this invention has been published in the National Publication No. 10-2020-0031889 (published in Korea on March 25, 2020, invention name: Circular Arrangement Shelf Type Shoe Drying Device). Summary of the Invention

Preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. In the accompanying drawings, the same reference numerals represent the same or similar components.

[0062] [Overall structure of the shoe care device]

[0063] Figure 1 1 is a front perspective view of a shoe care device 1 according to an embodiment of the present invention. Figure 9 1 is a perspective view showing the inner flow path portion 40 of the shoe care device 1 according to an embodiment of the present invention. Figure 10 3 is a cross-sectional view showing a state where the shoe care device 1 according to an embodiment of the present invention is extended to the inside of a boot 320 .

[0064] like Figure 1 、 Figure 9 as well as Figure 10 As shown, the shoe care device 1 according to an embodiment of the present invention can dry the shoe 300 or sterilize it with steam, and can include various functions related to the care of the shoe 300, such as removing foreign matter adhering to the insole of the shoe 300.

[0065] The shoe care device 1 according to an embodiment of the present invention may include at least one of a housing 10 , a storage portion 50 , a first supply portion 90 , a second supply portion 180 , a third supply portion 200 , a rotation limiting portion 220 , a height measuring portion 230 , and a control portion 240 .

[0066] [Outer casing]

[0067] The housing 10 can be modified in various ways within the technical concept of including an electrical equipment compartment 20 for supplying air for drying the shoes 300. In one embodiment of the present invention, the housing 10 may include at least one of the electrical equipment compartment 20, a water supply unit 30, a water recovery unit 32, a housing body 34, and an inner flow path 40.

[0068] The electrical equipment room 20 forms the lower portion of the outer shell 10. A steam generator 24 and a main blower 22 are installed in the electrical equipment room 20. The steam generator 24 is a steam device that supplies sterilizing steam to the first supply unit 90. The steam generator 24 generates steam by heating supplied water. The steam generated in the steam generator 24 is supplied to the shoes 300, thereby shortening the time required for sterilization and deodorization of the shoes 300.

[0069] The main blower 22 is connected to the steam generator 24 and transmits the steam generated in the steam generator 24 to the first supply unit 90 through the inner flow path 40 provided inside the outer shell 10. A fan and a motor are provided inside the main blower 22, and steam or air is supplied to the first supply unit 90 through the passage provided inside the outer shell 10.

[0070] Furthermore, the housing 10 is provided with a water supply unit 30 for supplying water to the steam generator 24. The water supply unit 30 has a box shape for storing water and is detachably provided on the housing body 34.

[0071] Water generated by the steam injected into the storage portion 50 is collected in the water recovery portion 32. The water recovery portion 32 has a box shape for storing the water collected from the storage portion 50 and is detachably provided on the housing body 34.

[0072] The inner flow path 40 is a passage connecting the electrical equipment room 20 and the first supply unit 90. Air passing through the electrical equipment room 20 moves along the inner flow path 40 to the first supply unit 90. The inner flow path 40 forms a passage inside the housing body 34, which forms the main body of the outer shell 10. The inner flow path 40 is provided between the outer and inner surfaces of the housing body 34 and serves as a passage for the movement of air, steam, and the like.

[0073] Therefore, the air supplied from the electrical equipment room 20 to the inner flow path portion 40 can be supplied to the inner side of the shoe 300 through the first supply portion 90. Alternatively, the air supplied from the electrical equipment room 20 to the inner flow path portion 40 can be supplied to the inner side of the shoe 300 through the first supply portion 90, the second supply portion 180, and the third supply portion 200 in sequence.

[0074] [Storage]

[0075] The storage portion 50 is disposed inside the outer shell 10 and defines a storage space 64 for accommodating the shoes 300. The storage portion 50 has a box-like shape with an open front and can be modified in various ways within the technical scope of supporting the first supply portion 90. In one embodiment of the present invention, the storage portion 50 may include at least one of an upper side 60, a side surface 66, a backing plate 70, and a back surface 80.

[0076] The upper side 60 of the storage section 50, located above the storage space 64, is provided with a first supply unit 90. The upper side 60 has a plate-like shape, arranged horizontally or at an acute angle to the horizontal. The upper side 60 includes a movable hole 62, which serves as a hole for the first supply unit 90 to move. In one embodiment of the present invention, the first supply units 90 operate in pairs. Therefore, the upper side 60 includes two elongated movable holes 62.

[0077] The side surfaces 66 are located on both lower sides of the upper side surface 60 and have a plate shape extending in the vertical direction. The upper side surface 60 and the side surfaces 66 are connected to each other and are arranged in a "匚" shape opening downward.

[0078] The cushion part 70 is located on the lower side of the upper side surface 60 and can be variously deformed within the technical idea range of storing foreign objects dropped from the shoe 300 inside. The cushion part 70 of an embodiment of the present invention may include: a support cushion 76 provided on the lower surface of the storage part 50; and a folding cushion 72 located above the support cushion 76 and performing a folding or unfolding action.

[0079] The support cushion 76 is formed with a plurality of through holes on the upper side and has a space inside for storing foreign objects dropped from the shoe 300.

[0080] And, a folding cushion 72 is provided on the upper side of the support cushion 76. In a state where a shoe 300 with a relatively low height, such as a sports shoe 310, is placed on the upper sides of the support cushion 76 and the folding cushion 72, drying and cleaning operations of the shoe 300 can be performed.

[0081] For a shoe 300 with a height higher than that of the sports shoe 310, such as a boot 320, the boot 320 can be placed on the support cushion 76 for use in a state where the folding cushion 72 is folded. The folding cushion 72 of an embodiment of the present invention includes: a fixed cushion 73 fixed to the inside of the storage part 50; and a rotating cushion 74 rotatably provided on the fixed cushion 73.

[0082] The fixed cushion 73 can be arranged in the horizontal direction, and the rotating cushion 74 can be rotated and folded onto the upper side of the fixed cushion 73. In addition, the rotating cushion 74 can also be arranged side by side with the fixed cushion 73 through an unfolding action. A plurality of through holes are formed on the upper sides of the fixed cushion 73 and the rotating cushion 74, and there is a space inside for storing foreign objects dropped from the shoe 300.

[0083] The cushion part 70 is provided on the lower side of the shoe 300, and foreign objects dropped from the shoe 300 are stored in the cushion part 70 and do not fall into other shoes 300 located on the lower side of the shoe 300, so contamination of other shoes 300 can be prevented.

[0084] The back surface part 80 is provided at the rear side of the storage space 64 and has a plate shape extending in the vertical direction. In addition, the back surface part 80 can be arranged in a shape that is connected to or faces the inner flow path part 40 of the outer shell part 10. In addition, the back surface part 80 may further include a ventilation hole part 82 and a fan member 84.

[0085] The vent portion 82 forms a slit-shaped air discharge hole in the back portion 80 . Therefore, part of the air moving toward the first supply portion 90 through the inner flow path portion 40 can move into the storage space 64 through the vent portion 82 .

[0086] Furthermore, a fan member 84 for forcing air movement may be provided behind the vent portion 82. By the operation of the fan member 84, a portion of the air moving upward along the inner flow path 40 moves to the inside of the storage portion 50 through the vent portion 82.

[0087] The fan member 84 provided in the inner flow path portion 40 serves to forcibly blow air into the inner side of the storage portion 50 through the vent portion 82. In addition, the fan member 84 forces the fluid to move so that the air or steam moving along the inner flow path portion 40 can move to the inner side of the storage portion 50.

[0088] [First Supply Department]

[0089] Figure 2 1 is a perspective view showing a state where the rotating conduit section 130 is folded upward according to an embodiment of the present invention. Figure 3 1 is a perspective view showing a state where the rotating conduit portion 130 is rotated to the lower side according to an embodiment of the present invention. Figure 4 1 is a perspective view showing a state in which the second supply part 180 and the third supply part 200 extend to the lower side of the lower pipe part 202 according to an embodiment of the present invention. Figure 5 This is a perspective view showing the main components of a shoe care device 1 according to an embodiment of the present invention in an exploded manner.

[0090] like Figures 2 to 5 As shown, the first supply unit 90 is located above the storage unit 50, with the air-guiding conduit disposed within. Furthermore, the first supply unit 90 includes a conduit that extends toward the interior of the storage space 64 through various motions, including rotation. In one embodiment of the present invention, the first supply unit 90 rotates the air-guiding conduit, directing air supplied from the electrical equipment room 20 toward the interior of the storage unit 50.

[0091] The first supply unit 90 operates only when a shoe 300 is placed inside the storage unit 50. After the pipes move to the inside of the storage unit 50, air can be supplied to the inside of the shoe 300. Furthermore, after drying the shoe 300 placed in the storage unit 50, the first supply unit 90 returns to its initial position, making it easy to remove the shoe 300 from the storage unit 50.

[0092] The first supply unit 90 of an embodiment of the present invention may include at least one of a fixed pipeline unit 100 , a pipeline bracket 110 , a soft pipeline unit, a rotating pipeline unit 130 , a first driving unit 140 , an air supply unit 150 , and a heat exchange unit 160 .

[0093] Before or after drying the shoes 300, the first supply portion 90 is located on the inner side of the storage portion 50. Therefore, when storing the shoes 300 in the storage portion 50 or taking the shoes 300 out of the storage portion 50, the shoes 300 are prevented from interfering with other components, thereby improving user convenience.

[0094] By rotating the first supply portion 90 , the first supply portion 90 is bent toward the inside of the storage portion 50 , thereby increasing the volume of air supplied to the shoes 300 , thereby saving time and cost required for drying the shoes 300 .

[0095] [Fixed piping section]

[0096] The fixed conduit section 100 is located above the storage section 50, with the air-guiding conduit located inside. The fixed conduit section 100 is located above the storage space 64, restricting its movement. In one embodiment of the present invention, the fixed conduit section 100 includes a first conduit section 102 and a second conduit section 106.

[0097] The first duct section 102 is continuously disposed with the air supply section 150 and extends horizontally. Furthermore, the second duct section 106 bends downward from the end of the first duct section 102 and is connected to the soft duct section 120. Furthermore, the first duct section 102 includes an extended duct section 104, wherein the cross-sectional area of the inner duct of the extended duct section 104 gradually increases from the second duct section 106 toward the air supply section 150. A curved surface is formed on the inner side of the extended duct section 104. The extended duct section 104 can be formed in a trumpet shape, with the cross-sectional area of the inner channel gradually increasing toward the air supply section 150.

[0098] Therefore, the air flowing into the interior of the first duct section 102 through the air supply unit 150 gradually converges while passing through the expansion duct section 104. Consequently, the flow rate of the air moving through the second duct section 106 toward the soft duct section 120 increases. Furthermore, the operation of the air supply unit 150 increases the flow rate of the air supplied to the interior of the fixed duct section 100, thereby reducing the time required to dry the shoes 300.

[0099] The fixed pipe section 100 is formed as The second conduit portion 106 is curved along the curved surface, thereby reducing the increase in friction caused by the air passing through the first conduit portion 102 and the second conduit portion 106 in sequence contacting the inner side of the fixed conduit portion 100.

[0100] [Pipeline bracket]

[0101] The duct bracket 110 supports the first duct section 102 of the fixed duct section 100. The duct bracket 110 can be fixed to at least one of the housing portion 50 and the outer shell 10. In one embodiment of the present invention, the duct bracket 110 has an upright plate shape and supports the ends of the first duct section 102. Therefore, the duct bracket 110 extends horizontally, and two horizontally spaced first duct sections 102 are connected to the duct bracket 110. Alternatively, the duct bracket 110 can be located between the air supply unit 150 and the fixed duct section 100.

[0102] [Soft pipe section]

[0103] Figure 6 1 is a perspective view showing a state in which the second supply unit 180 is connected to the rotating pipe unit 130 according to an embodiment of the present invention. Figure 7 It is an exploded perspective view of the rotating pipe unit 130 , the second supply unit 180 , and the third supply unit 200 according to an embodiment of the present invention.

[0104] like Figure 6 and Figure 7 As shown, the flexible conduit section 120 is connected to the fixed conduit section 100 and can undergo various shape changes within the technical concept of changing its shape through rotation. The upper side of the flexible conduit section 120 of the present invention is connected to the fixed conduit section 100, and the lower side extends into the interior of the rotating conduit section 130. Thus, the connecting conduit section guides air received through the fixed conduit section 100 into the interior of the rotating conduit section 130.

[0105] Furthermore, the soft conduit section 120 is a conduit with multiple bends, allowing air discharged through the soft conduit section 120 into the rotating conduit section 130 to move in a zigzag pattern. In one embodiment of the present invention, the soft conduit section 120 includes a first soft tube 122 connected to the fixed conduit section 100, one side of which has a concave curved surface; and a second soft tube 124 connected to the first soft tube 122, one side of which has a convex curved surface.

[0106] First soft tube 122 is connected to the lower end of second conduit section 106 and has a downwardly curved, corrugated surface. Second soft tube 124 is connected to the lower end of first soft tube 122 and has a downwardly curved, corrugated surface. The shapes of first and second soft tubes 122, 124 change depending on the position of rotating conduit section 130.

[0107] The cross-sectional areas of the inner passages of the first soft tube 122 and the second soft tube 124 are formed to be the same, and the air flowing into the first conduit section 102 through the extended conduit section 104 moves to the soft conduit section 120 via the second conduit section 106 .

[0108] The soft conduit portion 120 may be configured in a shape having a curved surface along a corrugated shape, and may be deformed in various shapes such as a spiral or a twisted shape. Therefore, the air supplied to the inner side of the rotating conduit portion 130 through the soft conduit portion 120 may form a dynamic airflow.

[0109] The air supplied to the inner side of the rotating duct portion 130 through the soft duct portion 120 moves in a zigzag shape, thereby evenly drying the shoes 300 .

[0110] The soft pipe portion 120 may include silicone or rubber, and various materials may be used within the technical concept of a shape being deformed by an external force.

[0111] [Rotating pipe section]

[0112] The rotating conduit section 130 is connected to the soft conduit section 120 and can be variously modified within the technical concept of being located outside the second supply section 180. The rotating conduit section 130 receives air supplied via the fixed conduit section 100 or the soft conduit section 120 and extends toward the interior of the storage space 64 by rotating and moving in the longitudinal direction.

[0113] The rotating conduit unit 130 of one embodiment of the present invention is connected to the soft conduit unit 120 and rotates toward the inside of the storage space 64. The rotating conduit unit 130 rotates due to the action of the first drive unit 140. When no shoes 300 are inside the storage space 64, the rotating conduit unit 130 rotates toward the upper side of the storage space 64. Therefore, the rotating conduit unit 130 is positioned inside the fixed cover 170 through the movable hole 62 provided in the upper side 60.

[0114] When supplying air to the inside of the shoe 300 , the rotating duct 130 rotates due to the operation of the first driving unit 140 . The rotating duct 130 rotates to the inside of the storage portion 50 through the movable hole 62 and supplies air to the inside of the shoe 300 .

[0115] The rotating pipe portion 130 is rotatably disposed on the fixed cover portion 170 and operates in a first mode and a second mode through a rotational action. In the first mode, the rotating pipe portion 130 rotates toward the inside of the fixed cover portion 170 , and in the second mode, the rotating pipe portion 130 rotates toward the inside of the storage space 64 .

[0116] When the first supply unit 90 is not in operation, the soft conduit unit 120 and the rotating conduit unit 130 constituting the first supply unit 90 are stably housed inside the fixed cover unit 170 , thereby improving the durability of the components.

[0117] The rotating pipe portion 130 is rotatably disposed inside the fixed cover portion 170 to form a pipe with one side open.

[0118] The rotating conduit portion 130 of one embodiment of the present invention includes: a rotating conduit body 132, which forms the main body of the rotating conduit portion 130 and is formed in an angular tube shape; and a guide groove portion 136, which forms a groove on the inner side of the rotating conduit body 132 along the length direction of the rotating conduit body 132.

[0119] One side and the other side of the rotating pipe body 132 are respectively opened, and the soft pipe portion 120 is inserted into one side of the rotating pipe body 132 to supply air into the rotating pipe body 132 .

[0120] Furthermore, hinge protrusions 134 are provided on both sides of the rotating conduit body 132. These protrusions 134, projecting outward from the rotating conduit body 132, are configured to be inserted into grooves provided on the inner side of the fixed cover 170, allowing for rotation. Hinge protrusions 134 are provided on both sides of the rotating conduit portion 130, which protrudes upward from the upper side surface 60. These hinge protrusions 134 are rotatably attached to the fixed cover 170, which is fixed to the upper side of the upper side surface 60.

[0121] The guide groove portion 136 extends along the longitudinal direction on the inner side of the rotating conduit portion 130. The two guide groove portions 136 are arranged in pairs in parallel and at positions facing each other. In addition, a stopper protrusion 184 provided on the second supply portion 180 described later is guided to move linearly along the guide groove portion 136. In addition, a locking boss is provided at the end of the guide groove portion 136, so that the stopper protrusion 184 is locked to the end of the guide groove portion 136, thereby preventing it from escaping to the outside of the rotating conduit portion 130. The stopper protrusion 184 moves along the guide groove portion 136, so that the conduit body 182 can move linearly stably.

[0122] [First driving unit]

[0123] The first drive unit 140 is connected to the rotating conduit unit 130. Various types of drive devices can be used within the technical scope of supplying rotational power to rotate the rotating conduit unit 130. In one embodiment of the present invention, the first drive unit 140 includes a motor bracket 142 fixed to the housing 50 or the fixed cover 170; and a drive motor 144 fixed to the motor bracket 142 and connected to the rotation center axis of the rotating conduit unit 130 to rotate the rotating conduit unit 130.

[0124] The driving motor 144 may be directly connected to the rotation center of the rotating conduit portion 130 , or may be connected to the rotation center of the rotating conduit portion 130 after power of the driving motor 144 is transferred to a transmission to increase torque.

[0125] The motor bracket 142 is fixed to the upper side surface 60 of the storage portion 50. The drive motor 144 supported by the motor bracket 142 is provided in a shape extending through the side surface of the fixed cover portion 170. Furthermore, the output shaft of the drive motor 144 is connected to the hinge protrusion 134 of the rotating conduit portion 130. Therefore, the operation of the drive motor 144 causes the rotating conduit portion 130, including the hinge protrusion 134, to rotate.

[0126] The driving motor 144 may be a servo motor or a stepping motor, and is operated by a control signal from the control unit 240 , thereby rotating the rotating conduit unit 130 at a set angle.

[0127] [Air supply unit]

[0128] The air supply unit 150 is provided continuously with the fixed duct unit 100 and can be implemented in various modifications within the technical concept of blowing air into the fixed duct unit 100. In one embodiment of the present invention, the air supply unit 150 includes a rotating fan and is located at the inlet of the fixed duct unit 100.

[0129] An air supply unit 150 is provided at a position facing the extended duct section 104. The air supply unit 150, disposed between the extended duct section 104 and the inner flow path section 40, increases the flow rate of air moving from the inner flow path section 40 toward the extended duct section 104. The operation and rotation speed of the air supply unit 150 are controlled by the control unit 240.

[0130] [Heat exchange unit]

[0131] Heat exchange unit 160 is disposed continuously with air supply unit 150. Various types of heat exchange devices can be used within the technical scope of performing heat exchange with the air flowing into air supply unit 150. In one embodiment of the present invention, heat exchange unit 160 utilizes the Peltier effect to perform heat exchange with the air. Heat exchange unit 160 includes a Peltier element 162, a first heat exchange plate 164, and a second heat exchange plate 166.

[0132] The Peltier element 162 can function as a temperature regulator, such as a cooler or warmer, by utilizing the phenomenon that when an electric current is applied after two dissimilar metals are joined, the joint cools. The Peltier element 162 is formed in a plate shape, and its temperature is varied by the power supply. To supply air warmer than ambient temperature to the inside of the shoe 300, the first heat exchange plate 164, which faces the inlet of the fixed conduit section 100, is heated. Furthermore, in conditions such as summer, where ambient temperatures are above 30°C, the first heat exchange plate 164 can be cooled to reduce the temperature of the dried shoe 300.

[0133] First heat exchange plate 164 is connected to one side of Peltier element 162 and exchanges heat with air flowing into air supply unit 150. In one embodiment of the present invention, first heat exchange plate 164 is shaped like a plate that connects to Peltier element 162. Multiple heat exchange plates are provided on the side facing fixed conduit unit 100, thereby increasing the area for heat exchange with the air.

[0134] Therefore, since the area where the air moving toward the fixed pipe portion 100 through the first heat exchange plate 164 contacts the first heat exchange plate 164 increases, the heat exchange efficiency of the heat exchange portion 160 can be improved.

[0135] Second heat exchange plate 166 is connected to the other side of Peltier element 162 and exchanges heat with the air. In one embodiment of the present invention, second heat exchange plate 166 is shaped like a plate that connects to Peltier element 162. Multiple heat exchange plates are arranged in a direction opposite to first heat exchange plate 164, thereby increasing the area for heat exchange with the air.

[0136] Therefore, the area in which the air passing through the periphery of the second heat exchange plate 166 contacts the second heat exchange plate 166 increases, thereby improving the heat exchange efficiency of the heat exchange unit 160 .

[0137] Furthermore, during the drying process of the shoes 300 , the heat exchange unit 160 operates to adjust the temperature of the air supplied to the shoes 300 , thereby shortening the time required for drying the shoes 300 .

[0138] [Fixed cover]

[0139] like Figure 5 As shown, the fixed cover 170 is fixed to the storage portion 50 and has an inner space 175 for the rotating conduit portion 130 and the second supply portion 180 to be positioned above the storage portion 50. The fixed cover 170 surrounds the soft conduit portion 120 and is fixed to the storage portion 50. Furthermore, the fixed cover 170 is configured with an opening at the bottom and has an inner space 175 for the rotating conduit portion 130 to be positioned above the storage portion 50.

[0140] The inner space 175 of the fixed cover 170 communicates with the movable hole 62 of the upper side 60 . Therefore, the second supply part 180 and the third supply part 200 rotating together with the rotating pipe part 130 can be located in the inner space 175 of the fixed cover 170 .

[0141] By providing the fixed cover 170, leakage of air moving toward the upper side of the storage portion 50 through the movable hole 62 of the storage portion 50 can be cut off. In addition, foreign matter inside the outer shell 10 can be prevented from falling into the storage space 64 through the movable hole 62.

[0142] [Second Supply Department]

[0143] Figure 8 1 is a perspective view showing a state in which the third supply portion is provided in a curved shape according to an embodiment of the present invention. Figure 11 1 is a partially cutaway perspective view showing the main components of a shoe care device 1 according to an embodiment of the present invention. Figure 12 1 is a cross-sectional view showing the main structure of a shoe care device 1 according to an embodiment of the present invention.

[0144] like Figure 8 、 Figure 11 as well as Figure 12 As shown, the second supply portion 180 is located inside the first supply portion 90 and can be modified in various ways within the technical concept of protruding from the bottom side of the first supply portion 90 to supply air to the inside of the shoe 300. The second supply portion 180 is connected to the first supply portion 90 and extends downward from the first supply portion 90, which is rotated toward the inside of the storage portion 50.

[0145] Thus, the second supply unit 180 increases the length of the air supply path, making it easier to supply air received by the first supply unit 90 toward the inside of the shoe 300. The second supply unit 180 is connected to the first supply unit 90 and extends from the first supply unit 90, which rotates toward the inside of the storage unit 50, toward the inside of the shoe 300. Therefore, air supplied to the rotating duct portion 130 of the first supply unit 90 moves toward the shoe 300 through the second supply unit 180.

[0146] The second supply portion 180 extends toward the lower side of the first supply portion 90 , thereby increasing the volume of air supplied to the shoes 300 , thereby saving time and cost required for drying the shoes 300 .

[0147] The second supply portion 180 according to an embodiment of the present invention may include at least one of a pipe body 182 , a stopper protrusion 184 , a second driving portion 186 , a screw 190 , and a core member 196 .

[0148] [Pipeline main body]

[0149] The main pipe portion 182 is located inside the rotating pipe portion 130 and moves linearly along the rotating pipe portion 130 to extend the length of the air-guiding pipe. The main pipe portion 182 of one embodiment of the present invention is located inside the rotating pipe portion 130 and has a angular tube shape with two openings.

[0150] The pipe body 182 according to an embodiment of the present invention is a pipe extending in a straight line and has a square channel inside.

[0151] The duct body 182 moves linearly along the inside of the rotating duct 130, thereby extending the range of air discharged toward the bottom of the rotating duct 130. Furthermore, the convex stopper protrusions 184 protruding from the outside of the duct body 182 engage with the guide grooves 136 provided inside the rotating duct 130, thereby guiding the air to move linearly. The stopper protrusions 184 protrude from both sides of the duct body 182 and are provided inside the rotating duct 130.

[0152] The second supply portion 180 includes a stopper protrusion 184 that protrudes outward from the first supply portion 182. The first supply portion 90 includes a guide groove 136 that forms a groove extending in a linear direction on the inner side of the rotating conduit portion 130 facing the conduit main body 182. Therefore, the stopper protrusion 184 is guided to move linearly along the guide groove 136.

[0153] The second driving unit 186 is connected to the first supply unit 90. Since the second driving unit 186 generates rotational power, various types of driving devices can be used within the technical concept of moving at least one of the second supply unit 180 and the third supply unit 200 along the length direction of the first supply unit 90. In one embodiment of the present invention, the second driving unit 186 uses a motor that receives electrical energy to generate rotational power.

[0154] Second drive unit 186 is fixed inside rotating conduit unit 130, and screw 190 is connected to the output shaft of second drive unit 186. Screw 190 rotates by receiving power from second drive unit 186. When rotating conduit unit 130 rotates downward, rotating conduit unit 130 is arranged in an inclined direction that forms an acute angle with the vertical direction or a vertical line.

[0155] The second supply portion 180 of one embodiment of the present invention forms an acute angle with the inner pad 302 of the shoe 300 and descends obliquely toward the inner pad 302. Therefore, the airflow supplied to the inner side of the shoe 300 through the second supply portion 180 or sequentially through the second supply portion 180 and the third supply portion 200 contacts the inner pad 302 and moves obliquely toward the inner side of the shoe 300, thereby saving time and cost required for drying the shoe 300.

[0156] The second supply part 180 forms an acute angle with the inner pad 302 and descends obliquely toward the inner pad 302 , so that the third supply part 200 can be easily bent in oblique contact with the inner pad 302 , thereby improving the operational reliability of the third supply part 200 .

[0157] In addition, the third supply part 200 is connected to the lower side of the second supply part 180, and the third supply part 200 is in oblique contact with the inner pad 302, so that the bending movement of the third supply part 200 can be easily guided, thereby making it easier to move the air supplied to the inside of the shoe 300.

[0158] Figure 13 1 is a cross-sectional view showing a state in which the second supply unit 180 and the third supply unit 200 are moved to the upper side according to an embodiment of the present invention. Figure 14 1 is a perspective view showing a state where the screw 190 and the core member 196 are separated according to an embodiment of the present invention. Figure 15 1 is a perspective view showing a state in which a screw 190 and a core member 196 are combined in accordance with an embodiment of the present invention. Figure 16 This is a perspective view showing a state in which the core member 196 is moved upward along the screw 190 according to an embodiment of the present invention.

[0159] like Figures 13 to 16 As shown, the second driving part 186 is fixed to the rotating conduit part 130, and the screw 190 extends downward along the rotating conduit part 130. The screw 190 has a rod shape extending along the longitudinal direction of the rotating conduit part 130, and a thread is provided on the outer side of the screw 190 to form an open thread.

[0160] The screw 190 is located inside the rotating pipe portion 130 and the pipe body portion 182 , and rotates in a forward or reverse direction by the action of the second driving portion 186 .

[0161] The core member 196 is connected to the outside of the screw 190 and can be variously modified within the technical concept of being moved along the longitudinal direction of the screw 190 by the rotation of the screw 190 .

[0162] The core member 196 of one embodiment of the present invention is in the shape of a tube having an inner thread corresponding to the outer thread of the screw 190. Furthermore, the core member 196 linearly moves along the screw 190 as the screw 190 rotates, and is connected to the conduit body 182 or the lower conduit portion 202 located below the conduit body 182.

[0163] The core member 196 may be directly connected to the pipe body 182 or the lower pipe portion 202 , or may be connected to the pipe body 182 or the lower pipe portion 202 via an additional member as needed.

[0164] The core member 196 of one embodiment of the present invention has a soft tubular shape. In order to insert and connect the screw 190 therein, the core member 196 has a female thread on the inside thereof that connects to the thread provided on the outside of the screw 190 .

[0165] The fixed support portion 197 is connected to the core member 196 and the pipe body 182. Therefore, the pipe body 182, the fixed support portion 197 and the core member 196 are located inside the rotating pipe section 130 and move along the longitudinal direction of the rotating pipe section 130.

[0166] The fixed support portion 197 is connected to the upper portion of the core member 196 and is provided in a shape surrounding the outer side of the core member 196. In addition, the protrusion protruding from the fixed support portion 197 is fixed to the inner side of the duct body 182, so the fixed support portion 197, the core member 196, and the duct body 182 move together.

[0167] [Third Supply Department]

[0168] The third supply unit 200 is provided continuously with the second supply unit 180, contacts the inner pad 302 of the shoe 300, and curves toward the front of the shoe 300. The third supply unit 200 can be implemented in various modifications within the technical concept of switching the exhaust direction of the air moving downward along the second supply unit 180 toward the front of the shoe 300.

[0169] The third supply unit 200 moves together with the pipe body 182 by the operation of the second driving unit 186, forming a pipe that contacts the inner pad 302 of the shoe 300 and bends toward the inner side of the shoe 300. Furthermore, when the third supply unit 200 is separated from the shoe 300, its shape changes again from a curved pipe to a straight pipe.

[0170] Since the third supply part 200 contacts the inner pad of the shoe 300 and is bent toward the front of the shoe 300 , time and cost required for drying the shoe 300 can be saved.

[0171] The third supply unit 200 according to an embodiment of the present invention may include at least one of a lower conduit unit 202 , a variable conduit unit 208 , a roller member 209 , and a sterilization unit 212 .

[0172] [Lower piping section]

[0173] Figure 17 1 is a perspective view showing a state in which the second supply portion 180 and the third supply portion 200 extend from the rotating conduit portion 130 extending toward the inside of the storage portion 50 according to an embodiment of the present invention. Figure 18 2 is a cross-sectional view showing that the third supply portion 200 contacts and bends the inner pad 302 of the shoe according to an embodiment of the present invention. Figure 19 FIG. 1 is a perspective view showing an end portion of the third supply unit 200 according to an embodiment of the present invention.

[0174] like Figures 17 to 19As shown, the lower conduit portion 202 is located below the second supply portion 180 and is a conduit that contacts the inner pad 302 of the shoe 300 and bends toward the front of the shoe 300. The lower conduit portion 202 of the third supply portion 200, together with the conduit main body 182 of the second supply portion 180, is located inside the rotating conduit portion 130 of the first supply portion 90.

[0175] The lower duct section 202 is formed into a square tube shape, with both sides of the lower duct section 202 open. Furthermore, the lower duct section 202 forms an acute angle with the inner pad 302 of the shoe 300 and descends toward the inner pad 302. When the lower duct section 202 is perpendicular to the inner pad 302 and descends, air exhausted from the lower duct section 202 is likely to move upwards after contacting the inner pad 302. Therefore, when the rotating duct section 130 rotates toward the shoe 300, a virtual line extending from the rotating duct section 130 forms an acute angle with the horizontal line. Furthermore, the second supply section 180, which protrudes downward from the rotating duct section 130, and the virtual line extending from the third supply section 200 also form acute angles with the horizontal line.

[0176] Therefore, when the second supply part 180 and the third supply part 200 are located inside the first supply part 90 , the air discharged to the lower side of the first supply part 90 collides obliquely with the insole 302 of the shoe 300 , thereby being easily moved forward of the shoe 300 .

[0177] Alternatively, when the second supply portion 180 and the third supply portion 200 extend below the first supply portion 90, the roller member 209 provided in the third supply portion 200 contacts and moves with the inner pad 302 of the shoe 300, thereby deforming the shape of the third supply portion 200 into a curved shape. The third supply portion 200 deforming into a curved shape can supply air to the front of the shoe 300.

[0178] [Variable piping unit]

[0179] The variable conduit section 208 connects the lower conduit section 202 and the second supply section 180 and can be modified in various ways within the technical concept of changing its shape by external force. In one embodiment of the present invention, the variable conduit section 208 is formed as an elastic bellows that is deformed into a curved shape by external force. Furthermore, when the external force is removed, the variable conduit section 208 deforms into a straight tube.

[0180] When the position of the lower duct portion 202 changes, the shape of the variable duct portion 208 changes, so that air is smoothly supplied to the lower duct portion 202 , thereby improving the operational reliability of the device.

[0181] [Roller component]

[0182] The roller member 209 is rotatably provided on the lower side of the lower conduit portion 202 and rotates in contact with the inner pad 302 of the shoe 300 , thereby guiding the bending movement of the third supply portion 200 and reducing the friction of the third supply portion 200 .

[0183] The roller member 209 is rotatably mounted on a roller bracket 204 that projects from the lower conduit portion 202 toward the rear pad of the shoe 300. The roller bracket 204 is mounted on a side of the lower conduit portion 202 that faces the back portion 80 of the storage portion 50. The roller member 209 is rotatably mounted on the roller bracket 204.

[0184] The roller member 209 rotates in contact with the sole of the shoe 300 , so that the third supply part 200 can be easily bent inside the shoe 300 , thereby improving the operational reliability of the device.

[0185] [Sterilization Department]

[0186] The sterilizing unit 212 is provided below the lower conduit 202 and irradiates sterilizing light toward the inside of the shoe 300. The sterilizing unit 212 may use an LED that generates UVC ultraviolet rays. In addition, various light sources may be used to irradiate sterilizing light.

[0187] The sterilization unit 212 is provided below the third supply unit 200 and sterilizes the inner side of the shoe 300 by irradiating light. The sterilization unit 212 is operated under the control of the control unit 240.

[0188] The sterilizing unit 212 operates to sterilize the shoes 300 using sterilizing light, thereby cutting off pathogens that are transmitted through the shoes 300.

[0189] [Rotation restriction section]

[0190] The rotation restricting portion 220 can be variously modified within the technical concept of restricting the rotation of the core member 196 while allowing the core member 196 to move linearly along the lower conduit portion 202. The rotation restricting portion 220 of one embodiment of the present invention may include a rotation restricting protrusion 222 and a rotation restricting groove 224.

[0191] The rotation restricting projection 222 can be modified in various shapes within the technical concept of connecting the core member 196 to the lower conduit portion 202. The core member 196 is connected to the inner side of the lower conduit portion 202 by the rotation restricting projection 222. The rotation restricting projection 222 is provided on the lower outer side of the core member 196, is fixed to the core member 196, and can move along the length direction of the lower conduit portion 202 with the core member 196.

[0192] The rotation limiting protrusion 222 located on the inner side of the lower conduit portion 202 is inserted into the rotation limiting groove 224 formed on the inner side of the lower conduit portion 202. Since the rotation limiting protrusion 222 is inserted into the rotation limiting groove 224, the rotation of the core member 196 is restricted, allowing the core member 196 to move linearly along the length direction of the lower conduit portion 202.

[0193] The rotation restricting projection 222 is provided in a ring shape surrounding the lower side of the core member 196 , and the projection provided on the rotation restricting projection 222 is inserted into a rotation restricting groove 224 provided inside the lower conduit portion 202 .

[0194] The rotation limiting groove 224 has a groove shape formed on the inner side of the lower conduit section 202 along the longitudinal direction of the lower conduit section 202. The rotation limiting protrusion 222 is inserted into the rotation limiting groove 224 and is slidable. Therefore, when the lower conduit section 202 located below the rotating conduit section 130 is bent, the rotation limiting protrusion 222 connected to the core member 196 moves along the rotation limiting groove 224.

[0195] The length of the rotation restricting groove portion 224 is set in consideration of the length by which the rotation restricting protrusion 222 slides when the lower conduit portion 202 moves in a curved shape.

[0196] [Height measurement unit]

[0197] Figure 23 FIG. 1 is a block diagram of a shoe care device 1 according to an embodiment of the present invention.

[0198] like Figure 1 and Figure 23 As shown, the height measuring unit 230 is disposed inside the storage portion 50 and can be implemented in various variations within the technical concept of measuring the height of the shoe 300 stored in the storage portion 50 and transmitting the measured value to the control unit 240. In one embodiment of the present invention, the height measuring unit 230 includes a plurality of measuring sensors 232 disposed vertically along the side surface 66 of the storage portion 50.

[0199] The control unit 240 may operate only the first supply unit 90 by receiving the measurement value of the height measuring unit 230. Alternatively, the control unit 240 may operate the first supply unit 90 and the second supply unit 180 sequentially by receiving the measurement value of the height measuring unit 230.

[0200] In the present invention, by providing a foldable pad 72 and a height measuring part 230, the shoe care device 1 can be used for drying shoes 300 of low height such as sports shoes 310 and shoes 300 of higher height than sports shoes 310 such as boots 320, thereby saving the installation cost of the shoe care device 1.

[0201] [Operation Order of the First, Second, and Third Supply Units]

[0202] Hereinafter, the operation of the shoe care device 1 according to one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0203] Figure 20 FIG. 1 is a diagram showing a state in which the second supply portion 180 extends toward the lower side of the first supply portion 90 according to an embodiment of the present invention. Figure 21 FIG. 1 is a diagram showing a state in which the third supply unit 200 contacts the insole of the shoe 300 according to an embodiment of the present invention. Figure 22 1 is a diagram illustrating a state in which the third supply unit 200 is bent toward the front of the shoe 300 according to an embodiment of the present invention.

[0204] like Figure 3 as well as Figures 20 to 22 As shown, when there is no shoe 300 in the storage portion 50, the rotating conduit portion 130 rotates upward toward the inner space 175 of the fixed cover portion 170 provided on the upper side of the upper side 60. Therefore, the shoe 300 can be prevented from colliding with the rotating conduit portion 130 when the user places the shoe 300 in the storage portion 50.

[0205] like Figure 3 As shown, when the shoe 300 is placed in the storage portion 50, the measurement sensor 232 of the height measurement unit 230 senses the shoe 300 and sends a signal to the control unit 240. Furthermore, the height measurement unit 230 is provided with a plurality of measurement sensors 232 in the vertical direction, and thus measures the height of the shoe 300 and transmits the measured value to the control unit 240.

[0206] The control unit 240 determines whether to operate only the first drive unit 140 or to operate both the first drive unit 140 and the second drive unit 186 based on the value of the measured height of the shoe 300 .

[0207] When the controller 240 activates the first driver 140, the rotating duct 130 rotates by the power of the first driver 140. The rotating duct 130 located inside the fixed cover 170 rotates toward the bottom of the upper side 60 and stops at a position where air can be supplied to the inside of the shoe 300.

[0208] Furthermore, the control unit 240 operates the second driving unit 186 to cause the conduit body 182 to protrude downward from the rotating conduit unit 130. The screw 190 rotates due to the operation of the second driving unit 186, and the core member 196 screwed to the outside of the screw 190 moves downward along the screw 190.

[0209] Core member 196 has threads in its hollow portion that engage with threads provided on the outside of screw 190 and is connected to fixed support portion 197 to restrict rotation. Core member 196 is fixed to the inside of pipe body 182 by fixed support portion 197. Since pipe body 182 is located inside rotating pipe section 130, rotation of pipe body 182 is restricted.

[0210] The pipe body 182 moves downward as the core member 196 moves downward, and the lower pipe section 202 located below the pipe body 182 also connects the rotation restricting portion 220 as a medium to the lower side of the core member 196. Therefore, the pipe body 182 and the lower pipe section 202 move downward as the core member 196 moves downward.

[0211] On the other hand, air is supplied to the first supply portion 90 through the inner flow path portion 40 provided in the outer shell portion 10. The air moving through the inner flow path portion 40 may be air containing no steam or air containing steam.

[0212] In the case of air not containing steam, the air passing through the main blower 22 of the electrical equipment room 20 is received. The air exhausted from the main blower 22 passes through the inner flow path 40 provided inside the outer shell 10 and moves upward.

[0213] A portion of the air flowing through the inner flow path 40 is supplied to the inside of the storage portion 50 via the vents 82 of the back portion 80, thereby drying the shoes 300. The operation of the fan member 84 provided on the rear side of the back portion 80 facilitates the supply of a portion of the air flowing upward along the inner flow path 40 to the vents 82.

[0214] The air moving to the first supply portion 90 through the inner flow path portion 40 is supplied to the inner side of the shoe 300 , thereby drying the shoe 300 .

[0215] On the other hand, when air containing steam is supplied to the inner flow path portion 40 , the steam generated in the steam generator 24 moves to the inner flow path portion 40 together with the air exhausted from the main blower 22 , and then moves upwardly to where the storage portion 50 is located.

[0216] The air moving to the first supply unit 90 through the inner flow path 40 is supplied to the inner side of the shoe 300 and can be used for various purposes such as sterilizing the shoe 300 and removing odor from the shoe 300 .

[0217] The air supplied through the inner flow path section 40 is heated or cooled to a set temperature while passing through the heat exchange section 160. The air is then moved into the interior of the fixed duct section 100 by the air supply section 150. Furthermore, the air that has moved into the interior of the rotating duct section 130 through the flexible duct section 120 connected to the fixed duct section 100 forms a corrugated airflow due to the shape of the flexible duct section 120, and moves downwardly of the rotating duct section 130.

[0218] The air moved to the lower side of the lower duct portion 202 is sequentially supplied to the inner side of the shoe 300 through the duct main body 182 , the variable duct portion 208 , and the lower duct portion 202 , thereby drying the inner side of the shoe 300 .

[0219] On the other hand, the air supplied to the inside of the storage portion 50 through the vent portion 82 of the storage portion 50 dries the outside of the shoe 300 .

[0220] At this time, the main duct portion 182 extends below the rotating duct portion 130. The variable duct portion 208 and the lower duct portion 202 are sequentially connected below the main duct portion 182 and are arranged in a linearly extending tube shape. Therefore, air discharged through the first supply portion 90, the second supply portion 180, and the third supply portion 200 forms a linear airflow toward the inside of the shoe 300.

[0221] Furthermore, when the control unit 240 operates the second driving unit 186 to move the conduit body 182 further downward, the roller member 209 located below the third supply unit 200 contacts the insole 302 of the shoe 300 , thereby forming a curved conduit in the third supply unit 200 .

[0222] The third supply unit 200 descends obliquely toward the inner pad 302 of the shoe 300. The roller member 209 contacts the inner pad 302, causing the lower conduit unit 202 to rotate a predetermined angle about the variable conduit unit 208. The rotation of the lower conduit unit 202 increases the length of the variable conduit unit 208, causing the rotation-limiting protrusion 222 to move along the rotation-limiting groove 224.

[0223] The core member 196 functions to enable the second supply part 180 and the third supply part 200 to move up and down, and to maintain the shape of the third supply part 200 provided in a curved shape.

[0224] Therefore, the air moving from the first supply part 90 to the duct main body 182 of the second supply part 180 is sequentially supplied to the inside of the shoe 300 through the variable duct part 208 and the lower duct part 202 to dry the shoe 300 .

[0225] Since the third supply unit 200 forms a pipe in a bent state, the inner side of the shoe 300 can be dried uniformly and quickly.

[0226] In addition, various modifications are possible, such as including steam or a deodorant in the air supplied to the inside of the shoe 300. Furthermore, the sterilizing unit 212 provided in the lower duct portion 202 operates to sterilize bacteria on the inside of the shoe 300.

[0227] [Only the first supply unit is in operation]

[0228] The shoe care device 1 of the present invention may be provided with only the first supply portion 90 without providing the second supply portion 180 and the third supply portion 200 .

[0229] When the shoe 300 is placed in the storage portion 50, the measurement sensor 232 of the height measurement unit 230 senses the shoe 300 and sends a signal to the control unit 240. Furthermore, the height measurement unit 230 includes a plurality of measurement sensors 232 arranged in the vertical direction, thereby measuring the height of the shoe 300 and transmitting the measured value to the control unit 240.

[0230] The control unit 240 activates the first driving unit 140 based on the value of the height measured for the shoe 300. Consequently, the rotating duct unit 130 rotates using the power of the first driving unit 140. The rotating duct unit 130, located inside the fixed cover 170, rotates toward the inside of the storage unit 50 and stops at a position where air can be supplied to the inside of the shoe 300.

[0231] Furthermore, the air supplied through the inner flow path portion 40 is supplied to the inner side of the shoe 300 via the rotating duct portion 130. When the first supply portion 90 is not used, the rotating duct portion 130 is rotated to the upper side of the storage portion 50. When only the first supply portion 90 is used, the rotating duct portion 130 extends toward the inner side of the storage portion 50.

[0232] In addition, compared with the method of supplying air only from the storage part 50 toward the direction where the shoes 300 are placed, an additional pipe is provided to supply air toward the inside of the shoes 300, so the amount of air supplied to the inside of the shoes 300 is increased, thereby greatly saving the time and cost required for drying the shoes 300 and caring for the shoes 300.

[0233] [Only the second supply unit is in operation]

[0234] In the shoe care device 1 of the present invention, the rotating conduit portion 130 provided in the first supply portion 90 may be fixedly provided so as to extend toward the inside of the storage portion 50 without rotating.

[0235] Also, the second supply portion 180 is provided inside the fixed rotating conduit portion 130 and is capable of ascending and descending motions.

[0236] When the shoe 300 is placed in the storage portion 50, the measurement sensor 232 of the height measurement unit 230 senses the shoe 300 and sends a signal to the control unit 240. Furthermore, the height measurement unit 230 includes a plurality of measurement sensors 232 arranged in the vertical direction, thereby measuring the height of the shoe 300 and transmitting the measured value to the control unit 240.

[0237] The control unit 240 operates the second drive unit 186 based on the value of the height of the shoe 300. The control unit 240 operates the second drive unit 186 to move the duct body 182 to the lower side of the rotating duct unit 130.

[0238] Therefore, the air that moves to the duct main body 182 of the second supply part 180 through the first supply part 90 moves to the inside of the shoe 300 to dry the shoe 300 .

[0239] The second supply unit 180 extends downwardly from the rotating duct unit 130, extending the duct that supplies air to the inside of the shoe 300. This operation of the second supply unit 180 increases the amount of air supplied to the inside of the shoe 300, significantly reducing the time and cost required for drying and maintaining the shoe 300.

[0240] [Only the second and third supply units are in operation]

[0241] In the shoe care device 1 of the present invention, the rotating conduit portion 130 provided in the first supply portion 90 may be fixedly provided so as to extend toward the inside of the storage portion 50 without rotating.

[0242] Also, the second supply part 180 and the third supply part 200 are provided inside the fixed rotating pipe part 130 and can be raised and lowered.

[0243] When the shoe 300 is placed in the storage portion 50, the measurement sensor 232 of the height measurement unit 230 senses the shoe 300 and sends a signal to the control unit 240. Furthermore, the height measurement unit 230 includes a plurality of measurement sensors 232 arranged in the vertical direction, thereby measuring the height of the shoe 300 and transmitting the measured value to the control unit 240.

[0244] To cause the conduit body 182 to project downward from the rotating conduit unit 130, the controller 240 activates the second drive unit 186. The screw 190 rotates due to the activation of the second drive unit 186, and the core member 196 screwed to the outside of the screw 190 moves downward along the screw 190.

[0245] Core member 196 has threads in its hollow portion that engage with threads provided on the outside of screw 190 and is connected to fixed support portion 197 to restrict rotation. Core member 196 is fixed to the inside of pipe body 182 by fixed support portion 197. Since pipe body 182 is located inside rotating pipe section 130, rotation of pipe body 182 is restricted.

[0246] The pipe body 182 moves downward as the core member 196 moves downward, and the lower pipe section 202 located below the pipe body 182 also connects the rotation restricting portion 220 as a medium to the lower side of the core member 196. Therefore, the pipe body 182 and the lower pipe section 202 move downward as the core member 196 moves downward.

[0247] Therefore, the air moved to the second supply part 180 and the third supply part 200 through the first supply part 90 is supplied to the inside of the shoe 300 to dry the shoe 300 .

[0248] By extending the second supply part 180 and the third supply part 200 toward the lower side of the rotating pipe part 130, the pipe supplying air toward the inside of the shoe 300 is extended, so the amount of air supplied to the inside of the shoe 300 is increased, thereby greatly saving the time and cost required for drying the shoe 300 and caring for the shoe 300.

[0249] Furthermore, when the control unit 240 operates the second driving unit 186 to move the conduit body 182 further downward, the roller member 209 located below the third supply unit 200 contacts the insole 302 of the shoe 300 , thereby forming a curved conduit in the third supply unit 200 .

[0250] The third supply unit 200 descends obliquely toward the inner pad 302 of the shoe 300. The roller member 209 contacts the inner pad 302, causing the lower conduit unit 202 to rotate a predetermined angle about the variable conduit unit 208. The rotation of the lower conduit unit 202 increases the length of the variable conduit unit 208, causing the rotation-limiting protrusion 222 to move along the rotation-limiting groove 224.

[0251] The core member 196 functions to enable the second supply part 180 and the third supply part 200 to move up and down, and to maintain the shape of the third supply part 200 provided in a curved shape.

[0252] Therefore, the air moving from the first supply part 90 to the duct main body 182 of the second supply part 180 is sequentially supplied to the inside of the shoe 300 through the variable duct part 208 and the lower duct part 202 to dry the shoe 300 .

[0253] Since the third supply unit 200 forms a pipe in a bent state, the inner side of the shoe 300 can be dried uniformly and quickly.

[0254] The present invention has been described above with reference to exemplary drawings. However, the present invention is not limited to the embodiments and drawings described in this specification. It is obvious that a person skilled in the art can make various modifications within the scope of the technical concept of the present invention. Furthermore, even if the effects of the structure of the present invention are not explicitly described when describing the embodiments of the present invention, the effects that can be predicted by the structure should be clearly recognized.
