As shown, the door frame 110 is rotatably coupled to the body 20 so that the hinge unit 30 is coupled to the door frame 110 and the body 20, respectively. In this case, the hinge unit 30 is mounted on the main body 20 on the upper side with respect to the center of the circular door 10. The hinge unit 30 and the door 10 are rotatably connected at connection points P1 and P2 that are vertically asymmetric with respect to the horizontal center line C1 of the door 10. Further, the hinge unit 30 is arranged at a position eccentric with respect to the horizontal center line C2 of the clothing inlet 20a. As shown in FIGS. 4a and 4b, both the door 10 and the clothes inlet 20a are circular, but since the display unit 12 is arranged on one side of the door 10, the door 10 is centered on the clothes inlet 20a. Is formed in different circles. In such an asymmetric structure, in order to realize an open door structure, the hinge unit 30 is arranged at an eccentric position above the horizontal center line C2 of the clothing inlet 20a and has a unique structure.

As shown in the figure, the hinge unit 30 and the door 10 are rotatably connected by the connecting portion 33 at the connecting points P1 and P2 which are vertically asymmetric with respect to the horizontal center line C1 of the door 10.

The connecting portion 33 includes an upper connecting portion 33a arranged on the upper side and a lower connecting portion 33b arranged on the lower side with reference to the horizontal center line C1 of the door 10. Here, the upper connecting portion 33a and the lower connecting portion 33b each include at least one connecting portion. As shown in the figure, the upper connecting portion 33a and the lower connecting portion 33b are arranged so as to be asymmetric with respect to the horizontal center line C1 of the door 10.

Here, the connecting points P1 and P2 may be defined as an upper end point of the upper connecting portion 33a and a lower end point of the lower connecting portion 33b. For example, the position of the bushing 334 (see FIG. 5a) at the upper end of the upper connecting portion 33a and the position of the bushing at the lower end of the lower connecting portion 33b, which will be described later, are the connecting points P1 and P2.

As another example, the connecting points P1 and P2 may be defined as an intermediate point (center) of the upper connecting portion 33a and an intermediate point (center) of the lower connecting portion 33b. In this case, the position of the intermediate point of the bushing of the upper connecting portion 33a and the position of the intermediate point of the bushing of the lower connecting portion 33b, which will be described later, are the connecting points P1 and P2.

More specifically, the door 10 is formed so that the distance L1 from the horizontal center line C1 to the upper connecting portion 33a is larger than the distance L2 from the horizontal center line C1 to the lower connecting portion 33b. Here, the intermediate point C3 between the upper connecting portion 33a and the lower connecting portion 33b is located above the horizontal center line C1 of the door 10.

As described above, in the present invention, when the hinge unit 30 is arranged at an eccentric position with respect to the door 10, the centers of the circular door and the clothing inlet are at different positions, and the door is provided with a display unit. Provide a suitable door opening / closing structure.

In this case, the center of the hinge unit 30 is eccentrically arranged above the horizontal center line C2 of the clothing inlet 20a. Then, the hinge unit 30 has a structure in which the center of gravity and the center of gravity of the hinge unit 30 are eccentric with respect to the horizontal center line C1 of the door 10 and the horizontal center line C2 of the clothing inlet 20a.

Further, a through hole 23 is formed in the door accommodating portion 20b, the hinge unit 30 is shielded by the door accommodating portion 20b, and the connecting portion of the hinge unit penetrates the through hole 23 and is exposed to the door accommodating portion 20b. Similar to the connecting portion 33, the through hole 23 formed in the door accommodating portion 20b is formed vertically asymmetrically with respect to the horizontal center line C1 of the door 10. Therefore, in the hinge unit 30, the portion that penetrates the through hole 23 and is exposed to the door accommodating portion 20b is asymmetric with respect to the horizontal center line C2 of the clothing inlet 20a, or the center of the exposed portion is the clothing inlet. It is arranged above the horizontal center line C2 of 20a.

The eccentric structure of the present invention described above realizes a hinge unit capable of ensuring operation reliability when supporting a circular door whose center is different from that of the clothes inlet and whose weight on the upper side is heavier.

The structure of the eccentric hinge unit can be applied not only to a single hinge but also to a double hinge structure, and the detailed structure of such a hinge unit 30 will be described later.

As a more specific example, the front cover 21 is mounted on the front surface of the main body 20, the hinge unit 30 is mounted inside the main body 20, and is connected to the door 10 through the front cover 21.

As shown in the figure, the front cover 21 is formed with the clothes inlet 20a and the door accommodating portion 20b described above with reference to FIGS. 1 and 2. In the closed state of the door 10, the door 10 is housed in the door accommodating portion 20b, and the outer surface edge portion of the door 10 is arranged so as to be flush with the outer surface of the main body 20 adjacent thereto.

The through hole 23 is formed on the side wall of the door accommodating portion 20b, the hinge unit 30 is attached to a hinge bracket (not shown) provided in the main body 20, and at least a part of the hinge unit 30 is formed from the through hole 23 to the door accommodating portion. Exposed to 20b. The hinge bracket serves to connect the main body of the garment processing device and the hinge unit 30. In this case, since the hinge bracket is arranged on the upper side with respect to the center of the clothing inlet 20a, the hinge unit 30 is arranged at a position eccentric with respect to the clothing inlet 20a. As described above with reference to FIGS. 1 and 2, as one embodiment of the hinge unit 30 has a double hinge structure having two different rotation axes, the door 10 rotates 90 degrees or more and the door accommodating portion. Move away from 20b. Hereinafter, the structure of such a hinge unit 30 will be described in more detail with reference to FIGS. 5, 6a, 6b, 6c and 6d together with FIGS. 1 and 2.

5a is an exploded perspective view of the hinge unit of FIG. 3a, FIG. 5b is a side view of the hinge unit of FIG. 3a, and FIG. 5c is a perspective view of the hinge unit of FIG. 6c and 6d are operation diagrams showing an operation in which the door is opened by the hinge unit of FIG. 5a.

As shown in the figure, the hinge unit 30 includes a mounting portion 311 to be mounted on the main body, and the mounting portion 311 is formed so that the width (BW) of the lower end portion is narrower than the width (TW) of the upper end portion. In this case, the width is the distance of the width in the left-right direction when the door is viewed from the front. Here, the mounting portion 311 is formed so that the area on the lower side is smaller than the area on the upper side with reference to the horizontal center line C1 of the door 10. Therefore, the center of gravity or the center of gravity of the mounting portion 311 is located above the horizontal center line C1 of the door 10.

Further, the mounting portion 311 is formed so that the length from the horizontal center line C1 of the door 10 to the upper end of the mounting portion 311 is longer than the length from the horizontal center line C1 of the door 10 to the lower end of the mounting portion 311. That is, the mounting portion 311 is arranged at a position eccentric with respect to the horizontal center line C1 of the door 10.

The structure of the mounting portion 311 is a feature of the hinge unit eccentric with respect to the horizontal center line C1 of the door 10 described above, but is also applied to the double hinge structure described later.

As a specific example, the hinge unit 30 includes a base member 310 having a mounting portion 311.

The base member 310 is formed of a metal material having strength to support the door and durability that does not deform even when the door is opened or closed. More specifically, the base member includes a protruding portion 312 protruding from the mounting portion 311. For example, a plurality of projecting portions 313 and 314 project from the mounting portion 311 so as to be vertically asymmetric with respect to the horizontal center line C1 of the door.

The mounting portion 311 is a portion to be mounted on the main body of the garment processing device, and is mounted on, for example, a hinge bracket. In this case, since the hinge unit 30 is arranged at a position eccentric with respect to the clothing inlet 20a, the base member 310 is biased upward with respect to the horizontal center line C1 of the door 10, and the hinge, specifically, the hinge. It is attached to the bracket. In this case, the center between the plurality of projecting portions 313 and 314 of the base member 310 is mounted on the main body so as to be biased upward with respect to the horizontal center line C2 of the clothing inlet 20a.

Further, the mounting portion 311 is made of a plate-shaped member, and one side forms an arc so as to correspond to the shape of the clothing inlet 20a. Here, since the base member 310 is located on the upper side with respect to the center of the circular clothing inlet 20a, the one side is formed along an arc located on the upper left side of the circular clothing inlet 20a.

The protruding portion 312 is formed in the shape of a cantilever protruding from the mounting portion 311. In this case, the protruding portion 312 projects in a direction forming an obtuse angle with the mounting portion 311. For example, the protrusion 312 extends in the diameter direction of the garment slot and extends toward the front surface of the main body 20, that is, the protrusion 312 is inclined with respect to the mounting portion 311 and extends toward the front surface of the main body, and the front cover. It is formed so as to penetrate the through hole 23 of 21 and project into the door accommodating portion 20b.

More specifically, the protruding portion 312 includes a first protruding portion 313 and a second protruding portion 314 that are arranged apart from each other. As shown in the figure, the first protruding portion 313 is arranged on the upper side with reference to the horizontal center line C1 of the door, and the second protruding portion 314 is arranged on the lower side. In this case, the first protruding portion 313 and the second protruding portion 314 are coupled to the first connecting portion 331 described later.

As described above, the mounting portion 311 is formed so that the width of the lower end portion is narrower than the width of the upper end portion. The upper end portion is a portion close to the upper end portion of the mounting portion 311 and is located between the first protruding portion 313 and the upper end portion of the mounting portion 311 in this embodiment. Further, the lower end portion is a portion close to the lower end portion of the mounting portion 311 and is located between the second protruding portion 314 and the lower end portion of the mounting portion 311 in this embodiment.

In this case, both the first protruding portion 313 and the second protruding portion 314 are arranged above the center of the clothing inlet 20a. In this case, the first protruding portion 313 and the second protruding portion 314 are arranged separately from each other in the mounting portion 311 so that the width of the mounting portion 311 becomes narrower from the first protruding portion 313 to the second protruding portion 314. Is formed in. For example, the width of the mounting portion 311 of the first protruding portion 313 is formed to be wider than the width of the mounting portion 311 of the second protruding portion 314. Specifically, the width of the mounting portion 311 around the first protruding portion 313 is formed to be wider than the width of the mounting portion 311 around the second protruding portion 314.

Since one side of the mounting portion 311 forms an arc, the other side of the mounting portion 311 is formed of a straight line in the vertical direction so that the width of the mounting portion 311 changes. Therefore, the width of the mounting portion 311 becomes narrower from the upper side of the center of the clothing inlet 20a toward the center.

Further, the mounting portion 311 is formed so that the surface mounted on the main body is inclined. For example, at least a part of the mounting portion 311 is formed so as to be inclined with respect to the rotation axis of the connecting portion 33 so that the lower end portion of the mounting portion 311 is closer to the connecting portion than the upper end portion. That is, the connecting portion 33 is arranged in the vertical direction, and the mounting portion 311 is formed so as to be inclined at a preset angle θ with respect to the vertical direction. As shown in the figure, together with the upper end portion and the lower end portion, all the portions located between the first protruding portion and the second protruding portion are formed in an inclined form. Further, in order to correspond to this, the portion of the main body to which the mounting portion is mounted is also formed in an inclined form.

An insertion hole 315 into which a hinge shaft is inserted is formed at each end of the first protruding portion 313 and the second protruding portion 314. The hinge shaft is arranged at a fixed position with respect to the main body 20 and forms a rotation shaft of any of the double hinge structures, and is therefore referred to as a first rotation shaft 321.

As shown in the figure, the hinge unit 30 includes a connecting member 330, and the connecting member 330 is connected to the protrusion 312. In this case, the connecting member 330 is rotatably connected to the protrusion so as to move the center of rotation of the door.

In this case, the first rotating shaft 321 is a fixed shaft to which the connecting member 330 is rotatably connected. The connecting member 330 is formed so as to move the center of rotation of the door 10 between the closed state and the open state of the door 10. For example, the base member 310 is connected to the first connecting portion 331 of the connecting member 330, and the door is rotatably connected to the second connecting portion 332 of the connecting member.

In the double hinge structure, a first connecting portion 331 is formed at one end of the connecting member 330, and the first connecting portion 331 is rotatably connected to the base member 310 via the first rotating shaft 321. As another example, the first connecting portion 331 may be formed so as to slidably connect the connecting member 330 to the base member 310. In this case, the connecting member 330 is slidably coupled to the protruding portion of the base member 310 in place of the first rotating shaft. In this way, the first connecting portion 331 is movably coupled to the base member 310.

A second connecting portion 332 is formed at the other end of the connecting member 330 so that the rotation center of the door 10 moves between the closed state and the open state of the door 10, and the door 10 is formed on the second connecting portion 332. It is rotatably connected.

As shown in the figure, a second rotating shaft 322 is attached to the second connecting portion 332, and the rotation center of the door 10 is moved from the first connecting portion (or the first rotating shaft) to the second connecting portion due to the rotation of the door 10. (Or move to the second axis of rotation).

A bushing 334 is attached to the second rotating shaft 322, and a hinge holder 351 (see FIG. 3a) for coupling with the door 10 is coupled to the bushing 334. The hinge holder 351 is coupled to the door 10, and in order to shield the hinge holder 351, a holder cover 352 is attached to the door so as to cover the hinge holder 351.

The connecting member 330 includes a first member 335 extending in one direction and a second member 336 protruding from the end of the first member and extending in a direction different from the one direction. In this case, the first rotating shaft 321 is connected to one end of the first member 335, bent from the other end of the first member 335, and the second member 336 extends in the different direction. Further, a second rotating shaft 322 is attached to the end of the second member 336, and the door is rotatably coupled to the second rotating shaft 322.

In this case, the first member 335 is formed in a straight bar shape, and the second member 336 is formed in a curved bar shape. More specifically, the second member 336 forms an arc centered on the first connecting portion 331. Therefore, the second member 336 extends in the circumferential direction centered on the first connecting portion 331.

On the other hand, the hinge unit 30 is formed so as to accommodate at least a part of the electrical wiring 50 that electrically connects the control unit (main circuit board) provided in the main body and the display unit 12 (see FIG. 1). .. For example, an accommodation space for accommodating the electric wiring 50 is formed in at least a part of the hinge unit. The accommodation space forms an accommodation groove 337. Specifically, the accommodating groove 337 is provided in the connecting member 330. For example, the second member 336 is formed with an accommodating groove 337 for accommodating the electrical wiring 50, and a cover 338 covering the accommodating groove 337 is attached to the hinge unit 30. Here, the opening 339 of the accommodating groove 337 is arranged in the second connecting portion 332. As shown, an opening 339 is located at one end of the second connecting portion 332, and the electrical wiring 50 is connected to the main body via the opening 339 and the accommodating groove 337.

Since the accommodating groove 337 extends to the first member 335, the electrical wiring 50 is connected to the inside of the garment processing apparatus via the first connecting portion 331. The electrical wiring 50 is provided as a path for electrically connecting the door to the control unit inside the garment processing device.

On the other hand, the second member 336 projects from the end of the first member 335 in the closed state toward the front surface of the door.

The first member 335 and the second member 336 are arranged so that the angle between them forms an acute angle. Here, since the second member 336 is formed so as to intersect the protruding portion, one side of the door close to the first connecting portion 331 is arranged on the right side of the first connecting portion 331.

The connecting member 330 having the above structure is formed so as to rotate in a preset range around the first connecting portion 331 by rotating the door from the closed state (FIG. 6a). In this case, the first connecting portion 331 is formed so that the connecting member rotates about a first rotating shaft 321 to a preset angle.

On the other hand, as shown in FIGS. 6a, 6b and 6c, at least a part of the connecting member 330 passes through at least a part of the base member within the preset range by the rotation of the door. It is formed. For example, the second member 336 and the first member 335 sequentially pass through the protrusion and rotate.

In this way, when the second member 336 and the first member 335 sequentially pass through the protrusion 312 and rotate, they are opened to the boundary of the preset range (75 degrees in this example) (FIG. 6c, hereinafter). Then it will be in the intermediate open state). Here, the first connecting portion 331 is provided with a stopper (not shown) that restricts the connecting member from rotating in the direction of opening the door at the boundary. As shown in the figure, in the intermediate open state, the door 10 partially shields the clothes inlet 20a when viewed from the front.

Here, the second rotation shaft 322 rotates about the first rotation shaft 321 to the preset angle by rotating the door 10 in the intermediate open state, and moves in a direction away from the clothes inlet 20a. do.

When the door 10 continuously rotates about the first rotating shaft 321 from the intermediate open state, there is no step between the front cover 21 and the outer surface of the door 10, so that one side of the door is locked to the front cover 21. NS. The double hinge structure of this example is formed so that the center of rotation of the door 10 moves from the first connecting portion 331 to the second connecting portion 332 in the intermediate open state.

For example, since the rotation of the door 10 is restricted around the first rotating shaft 321 in the intermediate open state, when an external force is applied to the door 10, the door is centered on the second rotating shaft 322 as shown in FIG. 6d. Rotate to. For example, if the door 10 can be rotated by a specific angle (45 degrees in this example) about the second rotation shaft 322, the door 10 is further rotated by the specific angle from the intermediate open state and viewed from the front. The clothing inlet is opened until it is not shielded (open state).

The double hinge structure has been described above with a focus on the operation of opening the door 10, but the operation of closing the door 10 is the opposite of the above description. For example, when an external force is applied to the door in the direction of closing the door 10 in the open state, the door 10 rotates about the second rotation shaft 322 until the intermediate open state. When the external force is continuously applied, the connecting member 330 rotates around the first rotating shaft 321 together with the door 10 from the intermediate open state to the closed state, and is accommodated in the door accommodating portion 20b.

With the above structure and operation, a garment processing device capable of opening and closing the garment inlet is realized even though the door is a recessed type that does not protrude from the main body.
