  Due to such a double hinge structure, the door is 90 degrees even if the door is large and there is no step between the front surface and the outer surface of the door, or the recessed door in which the outer surface of the door does not protrude from the door accommodating portion. A mechanism for rotating and opening the clothes insertion port is realized.

  Hereinafter, the detailed structure of the door 10 will be described focusing on such a double hinge structure.

  3a is an exploded perspective view of the garment processing apparatus 1 shown in FIG. 1, FIG. 3b is an exploded perspective view of the door shown in FIG. 1, and FIGS. 4a and 4b are conceptual views showing a combined state of the door and the hinge unit. It is.

  Here, the clothing input port is formed in a circular shape, and the door 10 is formed in a circular shape (including a true circular shape and an elliptical shape) so as to correspond thereto. However, the present invention is not necessarily limited to this. The clothing input port and the door 10 may be formed in a polygonal shape (square, hexagon, etc.).

  As illustrated, the door 10 includes a door frame 110, a door window 120, and a door cover 140.

  The door frame 110 is formed with an opening 110a that faces the clothing insertion opening 20a when the door 10 is closed, and the door window 120 is provided in the door frame 110 so as to correspond to the opening 110a. The door window 120 is formed of a translucent material (glass, synthetic resin material, etc.), and is disposed so as to correspond to the clothing insertion port 20a when the door 10 is closed.

  As illustrated, the door frame 110 includes an outer frame 111 and an inner frame 112. The outer frame 111 and the inner frame 112 are made of a synthetic resin material (for example, ABS material, PC material, etc.).

  A door window 120 is attached to the door frame 110. The door window 120 is formed of a translucent material (glass, synthetic resin material, etc.), and is disposed so as to correspond to the clothing insertion port 20a when the door 10 is closed. In addition, a door cover 140 that forms the appearance of the door 10 is coupled to the door frame 110. The door cover 140 is formed of a light-transmitting glass material or a synthetic resin material.

  In the present embodiment, the door frame 110 and the door cover 140 are formed in a circular shape so as to correspond to the circular door 10. As illustrated, the door frame 110 is rotatably coupled to the main body 20, and the hinge unit 30 is coupled to the door frame 110 and the main 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 asymmetrical with respect to the horizontal center line C1 of the door 10. Moreover, the hinge unit 30 is arrange | positioned in the position eccentric with respect to the horizontal center line C2 of the clothing insertion port 20a. As shown in FIGS. 4a and 4b, both the door 10 and the clothing input port 20a are circular, but the display unit 12 is disposed on one side of the door 10, so the door 10 is centered on the clothing input port 20a. Are formed in different circles. In such an asymmetric structure, in order to realize the door opening structure, the hinge unit 30 is arranged at a position eccentric to the upper side of the horizontal center line C2 of the clothing insertion opening 20a and has a unique structure.

  As illustrated, the hinge unit 30 and the door 10 are rotatably connected by a connecting portion 33 at connection points P1 and P2 that are asymmetrical with respect to the horizontal center line C1 of the door 10.

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

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

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

  More specifically, the distance L1 from the horizontal center line C1 to the upper connecting portion 33a of the door 10 is formed to be larger than the distance L2 from the horizontal center line C1 to the lower connecting portion 33b. Here, an 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.

  Thus, the present invention is arranged when the hinge unit 30 is arranged at a position eccentric with respect to the door 10, the centers of the circular door and the clothing insertion port are at different positions, and the door is provided with the display unit. Provide a suitable door opening and closing structure.

  In this case, the center of the hinge unit 30 is eccentrically arranged above the horizontal center line C2 of the clothing insertion opening 20a. Then, the hinge unit 30 has a structure in which the centroid and the center of gravity of the hinge unit 30 are decentered with respect to the horizontal center line C1 of the door 10 and the horizontal center line C2 of the clothing insertion port 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 passes through 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 20 b is formed asymmetrically with respect to the horizontal center line C <b> 1 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 input port 20a, or the center of the exposed portion is the clothing input port. It is arranged above the horizontal center line C2 of 20a.

  The above-described eccentric structure of the present invention realizes a hinge unit that can ensure operational reliability when supporting a circular door that is different from the center of the garment insertion port and that has a heavier upper weight.

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

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

  As shown in the figure, the front cover 21 is formed with the door insertion portion 20b described above with reference to FIGS. When the door 10 is closed, the door 10 is accommodated in the door accommodating portion 20b, and the outer edge of the door 10 is disposed so as to be flush with the outer surface of the main body 20 adjacent thereto.

  The through-hole 23 is formed in the side wall of the door accommodating portion 20b, the hinge unit 30 is mounted on a hinge bracket (not shown) provided in the main body 20, and at least a part of the hinge unit 30 extends from the through-hole 23 to the door accommodating portion. 20b exposed. The hinge bracket serves to connect the main body of the clothing processing apparatus and the hinge unit 30. In this case, since the hinge bracket is disposed on the upper side with respect to the center of the clothing input port 20a, the hinge unit 30 is disposed at an eccentric position with respect to the clothing input port 20a. As described above with reference to FIGS. 1 and 2, the hinge unit 30 has a double hinge structure having two different rotation shafts as one embodiment of the hinge unit 30. Leave 20b. Hereinafter, the structure of the hinge unit 30 will be described in more detail with reference to FIGS. 1 and 2 and FIGS. 5, 6a, 6b, 6c, and 6d.

  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 of opening the door by the hinge unit of FIG. 5a.

  As shown in the figure, the hinge unit 30 includes a mounting portion 311 mounted on the main body, and the mounting portion 311 is formed such that the lower end width (BW) is smaller than the upper end width (TW). In this case, the said width | variety is the distance of the width | variety of the left-right direction when the said door is seen from the front. Here, the mounting portion 311 is formed such that the lower area is smaller than the upper area with respect to the horizontal center line C1 of the door 10. Therefore, the centroid or the center of gravity of the mounting portion 311 is located above the horizontal center line C <b> 1 of the door 10.

  The mounting portion 311 is formed such 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 disposed at a position eccentric with respect to the horizontal center line C <b> 1 of the door 10.

  The structure of the mounting portion 311 is a feature related to the hinge unit that is eccentric with respect to the horizontal center line C1 of the door 10 described above, but is also applied to a 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 not to be deformed even when the door is opened and closed. More specifically, the base member includes a protruding portion 312 that protrudes from the mounting portion 311. For example, a plurality of protruding portions 313 and 314 protrude 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 that is mounted on the main body of the clothing processing apparatus, 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 insertion opening 20a, the base member 310 is biased upward with respect to the horizontal center line C1 of the door 10, and specifically the hinge, specifically the hinge. Mounted on the bracket. In this case, the center between the plurality of projecting portions 313 and 314 of the base member 310 is attached to the main body so as to be biased upward with respect to the horizontal center line C2 of the clothing insertion port 20a.

  The mounting portion 311 is made of a plate-like member, and forms an arc so that one side corresponds to the shape of the clothing insertion port 20a. Here, since the base member 310 is located on the upper side with respect to the center of the circular clothing insertion port 20a, the one side is formed along an arc located on the upper left side of the circular clothing insertion port 20a.

  The protruding portion 312 is formed in a cantilever shape protruding from the mounting portion 311. In this case, the protruding portion 312 protrudes in a direction that forms an obtuse angle with the mounting portion 311. For example, the protruding portion 312 extends in the diameter direction of the clothing input port and extends in the front direction of the main body 20, that is, the protruding portion 312 is inclined with respect to the mounting portion 311 and extends in the front direction of the main body. 21 is formed so as to penetrate through the through hole 23 of 21 and protrude into the door accommodating portion 20b.

  More specifically, the protrusion 312 includes a first protrusion 313 and a second protrusion 314 that are spaced apart from each other. As illustrated, the first protruding portion 313 is disposed on the upper side with respect to the horizontal center line C1 of the door, and the second protruding portion 314 is disposed on the lower side. In this case, the 1st protrusion part 313 and the 2nd protrusion part 314 are couple | bonded with the 1st connection part 331 mentioned later.

  As described above, the mounting portion 311 is formed such 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 of the mounting portion 311, and is between the first protruding portion 313 and the upper end of the mounting portion 311 in this example. The lower end portion is a portion close to the lower end of the mounting portion 311, and is between the second projecting portion 314 and the lower end of the mounting portion 311 in this example.

  In this case, the first projecting portion 313 and the second projecting portion 314 are both disposed above the center of the clothing input port 20a. In this case, the first projecting portion 313 and the second projecting portion 314 are spaced apart from each other on the mounting portion 311, and the mounting portion 311 becomes narrower as going from the first projecting portion 313 to the second projecting portion 314. Formed. 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 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 insertion opening 20a toward the center.

  Further, the mounting portion 311 is formed so that a surface to be mounted on the main body is inclined. For example, at least a part of the mounting part 311 is inclined with respect to the rotation axis of the connecting part 33 so that the lower end part is closer to the connecting part than the upper end part of the mounting part 311. That is, the connecting portion 33 is disposed in the vertical direction, and the mounting portion 311 is formed to be inclined at a preset angle θ with respect to the vertical direction. As shown in the drawing, 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. Correspondingly, the portion of the main body where the mounting portion is mounted is also formed in an inclined form.

  An insertion hole 315 into which the 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 disposed at a fixed position with respect to the main body 20 and forms one of the rotation shafts of a double hinge structure, and is therefore referred to as a first rotation shaft 321.

  As illustrated, 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 rotation center 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 to move the rotation center of the door 10 between the closed state and the open state of the door 10. For example, the first connecting part 331 of the connecting member 330 is connected to the base member 310, and the door is rotatably connected to the second connecting part 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 to connect the connecting member 330 to the base member 310 so as to be slidable. In this case, the connecting member 330 is slidably coupled to the protruding portion of the base member 310 instead of the first rotating shaft. As described above, 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 center of rotation of the door 10 moves between the closed state and the open state of the door 10, and the door 10 is connected to 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 rotated from the first connecting portion (or the first rotating shaft) by the rotation of the door 10. (Or the second rotation axis).

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

  The connecting member 330 includes a first member 335 extending in one direction and a second member 336 protruding from an 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, and the second member 336 extends in the different direction by being bent from the other end of the first member 335. 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 with the first connecting portion 331 as the center.

  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 electrical wiring 50 is formed in at least a part of the hinge unit. The housing space forms a housing groove 337. Specifically, the accommodation groove 337 is provided in the connecting member 330. For example, the second member 336 has a housing groove 337 that houses the electrical wiring 50, and a cover 338 that covers the housing groove 337 is attached to the hinge unit 30. Here, the opening 339 of the accommodation groove 337 is disposed in the second connecting portion 332. As illustrated, 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 receiving groove 337.

  Since the housing groove 337 extends to the first member 335, the electric wiring 50 is connected to the inside of the clothing 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 clothing processing apparatus.

  Here, the connecting member 330 includes a lower connecting member 330a and an upper connecting member 330b arranged so as to be asymmetric with respect to the horizontal center line of the door, and the electric wiring 50 is provided via the upper connecting member 330b. Connected to the body. That is, the accommodation groove 337 for accommodating the electrical wiring 50 is formed in the upper connecting member 330b. More specifically, the second member 336 includes an upper member and a lower member that are respectively disposed above and below the horizontal center line of the door, and the accommodation space, for example, the accommodation groove 337 is formed in the upper member. The Therefore, it is possible to easily secure the path of the electrical wiring 50 that connects the inside and outside of the clothing processing apparatus.

  The double hinge structure will be further described. The first member 335 is formed so as to protrude from the first connecting portion 331 in a direction approaching the back surface of the door 10 when the door is closed. On the other hand, the 2nd member 336 protrudes in the direction which approaches the front surface of the said door from the edge part of the 1st member 335 in the said closed state.

  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 projecting portion, one side of the door close to the first connecting portion 331 is disposed on the right side of the first connecting portion 331.

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

  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.

  As described above, when the second member 336 and the first member 335 sequentially pass through the protruding portion 312 and rotate, it is opened to the boundary of the preset range (75 degrees in this example) (FIG. 6c, hereinafter). Then, it is in an intermediate open state). Here, the first connecting portion 331 includes 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, the intermediate open state is a state in which the door 10 partially shields the clothing input port 20a when viewed from the front.

  Here, when the door 10 rotates to the intermediate open state, the second rotation shaft 322 rotates around the first rotation shaft 321 up to the preset angle and moves away from the clothing input port 20a. To do.

  When the door 10 continues to rotate around the first rotation 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 one side of the door is locked to the front cover 21. The The double hinge structure of the present example is formed such that the rotation center of the door 10 moves from the first connection part 331 to the second connection part 332 in the intermediate open state.

  For example, since the rotation of the door 10 is restricted around the first rotation shaft 321 in the intermediate open state, when an external force is applied to the door 10, the door is centered on the second rotation shaft 322 as shown in FIG. Rotate to. For example, if the door 10 can be rotated about the second rotation axis 322 by a specific angle (45 degrees in this example), the door 10 further rotates by the specific angle from the intermediate open state and viewed from the front. The clothes input port 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 reverse of the above description. For example, when an external force is applied to the door in a direction to close 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, from the intermediate open state to the closed state, the connecting member 330 rotates around the first rotating shaft 321 together with the door 10 and is accommodated in the door accommodating portion 20b.

  With the structure and operation described above, a clothing processing apparatus capable of opening and closing the clothing input port is realized despite the depression door not projecting from the main body.

  The structure of the hinge unit described above can be modified in various forms. Hereinafter, the modified example will be described in more detail with reference to the drawings.

Since the connecting member has a structure in which the first member 335 and the second member 336 extend in a bar shape, a large bending moment may occur in the first connecting portion 331 due to the weight of the door. Therefore, the rotation guide part 340 is formed in a structure that reinforces the strength of the first connection part 331.

  For example, a guide groove 341 is formed in the protruding portion 312a, specifically, the second protruding portion 314a. Therefore, the second protruding portion 314a is formed to have a larger area than the second protruding portion 314 of the base member 310 described with reference to FIG. As illustrated, a guide protrusion 342 inserted into the guide groove 341 is disposed at a portion where the first member 335 and the second member 336 are connected. The guide groove 341 is formed in an arc shape centered on the first rotation shaft 321. In this case, the connecting member 330 rotates until the guide protrusion 342 is positioned at the end of the guide groove 341. Therefore, the guide groove 341 serves as a stopper and determines the amount of rotation of the connecting member 330.

  Therefore, as shown in FIGS. 8 a to 8 d, the guide protrusion 342 rotates around the first rotation shaft 321 while moving along the guide groove 341.

  According to the above structure, when the door rotates from the closed state to the intermediate open state, not only the rotation of the door is guided by the rotation guide part 340 but also the bending moment applied to the first connection part 331 is dispersed. The effect of doing.
