Here, the clothes slot is formed in a circle, and the door 10 is formed in a corresponding circle (including perfect circle and ellipse). However, the present invention is not necessarily limited to this. The clothes slot and door 10 may be polygonal (square, hexagonal, etc.).

As shown, door 10 includes door frame 110 , door window 120 and door cover 140 .

The door frame 110 is formed with an opening 110a facing the clothes inlet 20a when the door 10 is closed, and the door window 120 is provided on the door frame 110 to correspond to the opening 110a. The door window 120 is made of a translucent material (glass, synthetic resin material, etc.) and is arranged to correspond to the clothes inlet 20a when the door 10 is closed.

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

A door window 120 is attached to the door frame 110 . The door window 120 is made of a translucent material (glass, synthetic resin material, etc.) and is arranged to correspond to the clothes inlet 20a when the door 10 is closed. In addition, a door cover 140 forming the appearance of the door 10 is coupled to the door frame 110 . The door cover 140 is made of a translucent glass material or a synthetic resin material.

In this 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 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 the center of the circular door 10 as a reference. The hinge unit 30 and the door 10 are rotatably connected at connecting 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 to the horizontal center line C2 of the clothes inlet 20a. As shown in FIGS. 4a and 4b, the door 10 and the clothes inlet 20a are both circular. are formed in different circles. In such an asymmetrical structure, the hinge unit 30 is arranged at an eccentric position above the horizontal center line C2 of the clothes inlet 20a and has a unique structure in order to realize the open structure of the door.

As shown, the hinge unit 30 and the door 10 are rotatably connected by a connecting portion 33 at connection points P1 and P2 that are vertically asymmetric with respect to the horizontal centerline C1 of the door 10 .

The connecting portion 33 includes an upper connecting portion 33a arranged above the horizontal center line C1 of the door 10 and a lower connecting portion 33b arranged below. Here, the upper connecting portion 33a and the lower connecting portion 33b each include at least one connecting portion. As shown, the upper connecting portion 33a and the lower connecting portion 33b are arranged asymmetrically with respect to the horizontal center line C1 of the door 10. As shown in FIG.

Here, the connection points P1 and P2 may be defined as the upper end point of the upper connection portion 33a and the lower end point of the lower connection 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 the midpoint (center) of the upper connecting portion 33a and the midpoint (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 distance L1 from the horizontal center line C1 of the door 10 to the upper connecting portion 33a is formed to be greater 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. As shown in FIG.

As described above, the present invention can be applied to the case where the hinge unit 30 is arranged at an eccentric position with respect to the door 10, the centers of the circular door and the clothes inlet are at different positions, and the door is provided with the display unit. To provide a suitable door opening/closing structure.

In this case, the center of the hinge unit 30 is arranged eccentrically above the horizontal center line C2 of the clothes inlet 20a. Then, the hinge unit 30 has a structure in which the centroid 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 clothes inlet 20a.

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. As with the connecting portion 33 , the through hole 23 formed in the door accommodating portion 20 b is vertically asymmetrical with respect to the horizontal centerline C<b>1 of the door 10 . Therefore, in the hinge unit 30, the portion that passes through the through-hole 23 and is exposed to the door accommodating portion 20b is asymmetrical with respect to the horizontal center line C2 of the clothes inlet 20a, or the center of the exposed portion is the clothes inlet. It is positioned above the horizontal centerline C2 of 20a.

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

The structure of the eccentric hinge unit can be applied not only to the single hinge but also to the double hinge structure described above as an embodiment of the present invention. will be described later.

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

As shown, the front cover 21 is formed with the clothes inlet 20a and the door accommodating portion 20b described above with reference to FIGS. In the closed state of the door 10, the door 10 is received in the door receiving part 20b, and the outer surface edge 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 in the side wall of the door receiving portion 20b, the hinge unit 30 is mounted on a hinge bracket (not shown) provided on the main body 20, and at least a portion of the hinge unit 30 extends from the through hole 23 to the door receiving portion. 20b exposed. The hinge bracket serves to connect the main body of the laundry processing apparatus and the hinge unit 30 . In this case, since the hinge bracket is positioned above the center of the clothes inlet 20a, the hinge unit 30 is positioned eccentrically with respect to the clothes inlet 20a. As described above with reference to FIGS. 1 and 2, one embodiment of the hinge unit 30 has a double hinge structure with two different rotation axes, so that the door 10 can be rotated by 90 degrees or more to open the door receiving portion. Move away from 20b. Hereinafter, the structure of such a hinge unit 30 will be described in more detail with reference to FIGS. 1 and 2 as well as 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, FIG. 5c is a perspective view of the hinge unit of FIG. 6c and 6d are operation diagrams showing the operation of opening the door by the hinge unit of FIG. 5a.

As shown, the hinge unit 30 has a mounting part 311 mounted on the main body, and the mounting part 311 is formed such that the width (BW) of the lower end is narrower than the width (TW) of the upper end. In this case, the width is the width in the horizontal direction when the door is viewed from the front. Here, the mounting part 311 is formed so 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 center of gravity of the mounting portion 311 is located above the horizontal center line C1 of the door 10 .

Also, 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 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 characteristic of the hinge unit eccentric with respect to the horizontal center line C1 of the door 10 described above, but it is also applied to the double hinge structure described later.

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

The base member 310 is made of a metal material having strength to support the door and durability such that it is not deformed even when the door is opened and closed. More specifically, the base member has 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 asymmetrical with respect to the horizontal center line C1 of the door.

The attachment part 311 is a part attached to the main body of the clothes processing apparatus, and is attached to, for example, a hinge bracket. In this case, since the hinge unit 30 is arranged at an eccentric position with respect to the clothes slot 20a, the base member 310 is biased upward with respect to the horizontal center line C1 of the door 10, and the main body, specifically the hinge, is biased upward. attached to the bracket. In this case, the center between the protrusions 313 and 314 of the base member 310 is biased upward with respect to the horizontal center line C2 of the clothes inlet 20a.

Moreover, the mounting portion 311 is made of a plate-like member and has one side that forms an arc corresponding to the shape of the clothing inlet 20a. Here, since the base member 310 is positioned above the center of the circular clothes inlet 20a, the one side is formed along an arc positioned on the upper left side of the circular clothes inlet 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 forming an obtuse angle with the mounting portion 311 . For example, the protruding part 312 extends in the diametrical direction of the clothes inlet and extends in the front direction of the main body 20, that is, the protruding part 312 extends in the front direction of the main body while being inclined with respect to the mounting part 311, and the front cover 21 through a through hole 23 to protrude into the door accommodating portion 20b.

More specifically, the protrusion 312 includes a first protrusion 313 and a second protrusion 314 spaced apart from each other. As shown, the first protruding portion 313 is positioned above the horizontal center line C1 of the door, and the second protruding portion 314 is positioned below. In this case, the first protruding portion 313 and the second protruding portion 314 are coupled to a first connecting portion 331, which will be described later.

As described above, the mounting part 311 is formed such that the width of the lower end is narrower than the width of the upper end. The upper end portion is a portion near 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 near 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, both the first protruding portion 313 and the second protruding portion 314 are arranged above the center of the clothes inlet 20a. In this case, the first protruding portion 313 and the second protruding portion 314 are arranged separately from each other on the mounting portion 311 , and the width of the mounting portion 311 is decreased from the first protruding portion 313 to the second protruding portion 314 . 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 a vertical straight line so that the width of the mounting portion 311 varies. Therefore, the width of the mounting portion 311 becomes narrower toward the center from the upper side of the center of the clothing inlet 20a.

In addition, the mounting part 311 is formed so that the surface mounted on the main body is inclined. For example, at least a portion of the mounting portion 311 is 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 of the mounting portion 311 . That is, the connection part 33 is arranged in the vertical direction, and the mounting part 311 is formed to be inclined at a predetermined angle θ with respect to the vertical direction. As shown, the upper end portion, the lower end portion, and the portion located between the first protruding portion and the second protruding portion are all formed in a slanted shape. Correspondingly, a portion of the main body on which the mounting portion is mounted is also formed in a slanted shape.

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 . Said hinge axis is arranged in a fixed position with respect to the main body 20 and forms either axis of rotation of the double hinge structure, hence the first axis of rotation 321 .

As shown, the hinge unit 30 includes a connecting member 330 that 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 serves as a fixed shaft to which the connecting member 330 is rotatably connected. The connecting member 330 is formed to move the center of rotation of the door 10 between the closed state and the open state of the door 10 . For example, a first connecting portion 331 of a connecting member 330 is connected to the base member 310, and the door is rotatably connected to a second connecting portion 332 of the connecting member.

In the example of the eccentric hinge structure, the connecting portion 33 described above becomes the second connecting portion 332 . Here, the door is rotatably coupled to one end of the protrusion 312 so that the protrusion 312 becomes the connecting member 330 . In this case, the portion of the hinge unit 30 that penetrates through the through-hole 23 and is exposed to the door accommodating portion serves as a connecting portion provided at a part of the projecting portion and an end portion of the projecting portion. The connection part is asymmetrically arranged with respect to the horizontal center line of the door.

In the double hinge structure, a first connection part 331 is formed at one end of the connection member 330 , and the first connection part 331 is rotatably connected to the base member 310 through the first rotation shaft 321 . As another example, the first connecting part 331 may be formed to slidably connect the connecting member 330 to the base member 310 . In this case, the connection member 330 is slidably coupled to the protrusion of the base member 310 instead of the first rotating shaft. As such, the first connection part 331 is movably coupled to the base member 310 .

A second connection portion 332 is formed at the other end of the connection 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 connected to the second connection portion 332. rotatably connected.

As shown, the second rotating shaft 322 is attached to the second connecting portion 332, and the rotation center of the door 10 moves from the first connecting portion (or the first rotating shaft) to the second connecting portion as the door 10 rotates. (or second rotation axis).

A bushing 334 is mounted on 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. As shown in FIG. The hinge holder 351 is coupled to the door 10 , and a holder cover 352 is mounted on the door to cover the hinge holder 351 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 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, and the other end of the first member 335 is bent to extend the second member 336 in the different direction. Also, the second rotating shaft 322 is mounted on 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 the shape of a straight bar, and the second member 336 is formed in the shape of a curved bar. 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 around the first connecting portion 331 .

On the other hand, the hinge unit 30 is formed so as to accommodate at least part of the electrical wiring that electrically connects the control section (main circuit board) provided in the main body and the display section 12 (see FIG. 1). For example, at least a portion of the hinge unit is formed with a receiving groove 337 for receiving the electrical wiring. Specifically, the second member 336 is formed with an accommodation groove 337 that accommodates the electrical wiring, and a cover 338 that covers the accommodation groove 337 is attached to the hinge unit 30 . Since the receiving groove 337 extends to the first member 335 , the electrical wiring is connected to the interior of the laundry processing apparatus via the first connecting portion 331 . The electrical wiring is provided as a path for electrically connecting the door to a control unit inside the clothes processing apparatus.

Here, the connecting member 330 includes a lower connecting member 330a and an upper connecting member 330b that are asymmetrically arranged with respect to the horizontal center line of the door, and the electrical wiring is routed through the upper connecting member 330b. lead to the body; That is, the receiving groove 337 for receiving the electrical wiring is formed in the upper connecting member 330b. More specifically, the second member 336 includes an upper member and a lower member that are vertically arranged with respect to the horizontal center line of the door, and the receiving groove 337 is formed in the upper member. Therefore, it is possible to easily secure the electrical wiring path connecting the inside and outside of the clothes processing apparatus.

To further explain the double hinge structure, the first member 335 is formed to protrude from the first connecting portion 331 toward the rear surface of the door 10 when the door is closed. On the other hand, the second member 336 protrudes from the end of the first member 335 toward the front surface of the door in the closed state.

The first member 335 and the second member 336 are arranged such that the angle between them forms an acute angle. Here, since the second member 336 is formed to intersect the protrusion, one side of the door closer to the first connection part 331 is disposed on the right side of the first connection part 331 .

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

Meanwhile, as shown in FIGS. 6a, 6b and 6c, at least a portion of the connecting member 330 passes through at least a portion of the base member within the preset range as the door rotates. It is formed. For example, the second member 336 and the first member 335 are sequentially rotated past the protrusion.

In this way, when the second member 336 and the first member 335 are sequentially rotated past the projection 312, it will open to the boundary of the preset range (75 degrees in this example) (FIG. 6c, below). is called an intermediate open state). Here, the first connection part 331 is provided with a stopper (not shown) that restricts the rotation of the connection member in the door opening direction at the boundary. As shown in the drawing, the intermediate open state is a state in which the door 10 partially covers the clothes inlet 20a when viewed from the front.

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

When the door 10 continues to rotate about the first rotating shaft 321 from the intermediate open state, one side of the door is locked to the front cover 21 because there is no step between the front cover 21 and the outer surface of the door 10. be. The illustrated double hinge structure is formed such 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 rotation axis 321 in the intermediate open state, when an external force is applied to the door 10, the door rotates around the second rotation axis 322 as shown in FIG. 6d. 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 is further rotated by the specific angle from the intermediate open state and is viewed from the front. to open the clothing inlet to a non-blocking state (open state).

Although the double hinge structure has been described above, focusing on the operation of opening the door 10, 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 the direction of closing the door 10 in the open state, the door 10 rotates around the second rotating shaft 322 until the intermediate open state. When the external force is continuously applied, the connecting member 330 rotates about the first rotating shaft 321 together with the door 10 and is received in the door receiving portion 20b from the intermediate open state to the closed state.

With the structure and operation described above, a laundry processing apparatus capable of opening and closing the laundry loading port is realized in spite of having a recessed door that does not protrude from the main body.

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

7 is an exploded perspective view of a hinge unit showing another embodiment of the present invention, and FIGS. 8a, 8b, 8c and 8d are operation diagrams showing the operation of opening the door by the hinge unit of FIG. be.

Similar to the hinge unit described above with reference to FIG. is as described above. For example, the base member 310 includes a mounting portion 311 and a projecting portion 312a, the connecting member 330 includes a first member 335 and a second member 336, the first rotating shaft 321 forms the first connecting portion 331, and the second Two rotating shafts 322 form a second connecting portion 332 . The protrusion 312a includes a first protrusion 313 and a second protrusion 314a. Further, the center of rotation moves from the first rotating shaft 321 to the second rotating shaft 322 by rotating the door from the closed state to the open state.

As shown, the hinge unit further includes a rotation guide part 340 . Since the connecting member has a structure in which the first member 335 and the second member 336 extend like bars, a large bending moment may be generated at the first connecting portion 331 due to the weight of the door. Accordingly, 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. To this end, 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 shown, a guide protrusion 342 inserted into a guide groove 341 is arranged 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 centering on the first rotating 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 .

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

According to the above structure, when the door rotates from the closed state to the intermediate open state, the rotation of the door is guided by the rotation guide portion 340, and the bending moment applied to the first connecting portion 331 is dispersed. bring about the effect of Therefore, according to this example, a laundry processing apparatus having a more compact hinge structure and improved opening/closing reliability of the recessed door is realized.
