Description

CLOTHES TREATING APPARATUS BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a laundry treating apparatus, and more particularly, to a laundry treating apparatus having a door for opening and closing a laundry introduction opening of a body. 2. Background of the Invention A laundry treating apparatus includes a laundry washing apparatus, a laundry drying apparatus, a laundry washing/drying apparatus. In the laundry treating apparatus, a washing process means a process to remove contaminants of laundry by interaction between water and detergent, and a drying process means a process to remove moisture included in laundry by a hot blast supply device provided at the laundry treating apparatus. A general laundry treating apparatus includes a body which forms appearance of the laundry treating apparatus and having a laundry introduction opening, a laundry accommodation unit provided in the body, a driving unit for rotating a drum which constitutes the laundry accommodation unit, and a door for opening and closing the laundry introduction opening.
In the general laundry treating apparatus, the door is designed to open and close the laundry introduction opening, and to allow a user to view the laundry accommodation unit therethrough. In this case, an open angle of the door may be restricted due to a limited design of the laundry treating apparatus. In order to solve such a problem, Korean Laid-Open Utility Model No. 20-1999-0029441, etc. have disclosed a structure to open and close a door in a drum-type washing machine with an increased open angle. However, the structure has a degraded appearance due to the quadrangular door and fixing plate of a hinge unit. Further, since the hinge unit has a simple structure, reliability in opening the door or durability of the hinge unit is lowered.
Especially, in case of a concaved-type door having no gap between its outer surface and a front surface of a laundry treating apparatus, the conventional door opening/closing structure may not be applied, because a large open angle should be implemented with a simple appearance of the laundry treating apparatus, an operation reliability should be implemented, etc.
Further, in case of a door asymmetric with a laundry introduction opening (e.g., a circular door having a display unit), a mechanism to open and close the door should be much considered.
Thus, the present invention provides a method capable of enhancing an operation reliability, with obtaining a simple appearance of a laundry treating apparatus.
SUMMARY OF THE INVENTION
Therefore, an aspect of the detailed description is to provide a laundry treating apparatus provided with a hinge mechanism having an operation reliability with supporting a circular door having a display unit mounted thereto.
Another aspect of the detailed description is to provide a laundry treating apparatus having a simple appearance, and having an efficient electric connection path for controlling a display unit mounted to a door.
To achieve these and other advantages and in accordance with the purpose of this specification, as embodied and broadly described herein, there is provided a laundry treating apparatus, including: a body having a laundry introduction opening of a circular shape; a door having a display unit, having a circular shape eccentric from the laundry introduction opening, and configured to open and close the laundry introduction opening; a controller electrically connected to the display unit, and provided at the body; and a hinge unit mounted to the body, configured to rotatably connect the door to the body, and formed to accommodate therein at least part of an electric wire for electrically connecting the controller to the display unit.
An accommodation space configured to accommodate the electric wire therein may be formed on at least part of the hinge unit. An accommodation groove may be formed at the accommodation space, and a cover configured to cover the accommodation groove may be mounted to the hinge unit. The electric wire may be connected from the door to the body through the hinge unit.
According to another aspect of the present invention, connection points between the hinge unit and the door may be asymmetric to each other based on a horizontal center line of the door. The electric wire may be connected from the door to the body through at least one of the connection points.
The hinge unit may be provided with a mounting portion mounted to the body, and the mounting portion may be formed such that a width of a lower end region thereof is different from a width of an upper end region thereof. In this case, in a single hinge structure, the electric wire may be connected from the door to the body through protrusions protruded from the mounting portion. In case of a dual hinge structure, the electric wire may be connected from the door to the body through a connection member connected to the protrusions.
The laundry treating apparatus of the present invention may have the following advantages.
Firstly, since the accommodation space configured to accommodate an electric wire therein is formed at the hinge unit, a path of the electric wire for connecting the inside of the laundry treating apparatus with the outside may be obtained more easily.
Further, a door opening/closing structure suitable for a case where the circular door and the circular laundry introduction opening are eccentric from each other and the door is provided with the display unit, may be provided by arranging the hinge unit in a biased manner on the basis of the door or the laundry introduction opening.
Further scope of applicability of the present application will become more apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from the detailed description.

For the sake of brief description with reference to the drawings, the same or equivalent components will be provided with the same reference numbers, and description thereof will not be repeated. A singular expression in the specification includes a plural meaning unless it is contextually definitely represented.
In describing the present invention, the detailed description will be omitted when a specific description for publicly known technologies to which the invention pertains is judged to obscure the gist of the present invention. FIG. 1 is a perspective view illustrating a laundry treating apparatus 1 according to an embodiment of the present invention. FIGS. 2A and 2B are conceptual views illustrating an open state of a laundry introduction opening 20a, the open state implemented as a door 10 shown in FIG. 1 is rotated primarily and secondarily, respectively.
Referring to the drawings, the laundry treating apparatus 1 includes a body 20 and a door 10.
The body 20 forms appearance of the laundry treating apparatus 1, and is provided with the laundry introduction opening 20a into which laundry is introduced. In this embodiment, the laundry introduction opening 20a is formed on a front surface of the body 20 having a hexahedral shape. A laundry accommodation unit, configured to accommodate laundry therein through the laundry introduction opening 20a, is provided in the body 20.
For instance, if the laundry treating apparatus 1 according to the present invention serves to dry laundry, the laundry accommodation unit may be configured as a drum 40 rotatably provided in the body 20.
As another example, if the laundry treating apparatus 1 according to the present invention serves to wash and dry laundry, the laundry accommodation unit may be configured as a tub (not shown) provided in the body 20 and configured to store washing water therein, and a drum 40 rotatably provided in the tub and configured to accommodate laundry therein. A driving unit (not shown) configured to rotate the drum 40 is provided at the body 20. The driving unit may include a motor configured to generate a driving force, and a belt configured to rotate the drum 40 using the driving force. A detergent supply unit (not shown) may be installed at the body 20 so as to be withdrawable and insertable, in the form of a drawer. A cover 21 configured to cover the detergent supply unit may be formed to be rotatable up and down. A power button 22, configured to turn on/off the laundry treating apparatus 1, may be provided at the body 20. When a display unit 12 is configured as a touch screen 12, the laundry treating apparatus 1 may be turned on/off by a touch input applied to the touch screen 12. In this case, the power button 22 is not provided.
The door 10 may be provided with a window unit 11 and the display unit 12.
In a closed state of the door 10, the window unit 11 is disposed to correspond to the laundry introduction opening 20a. With such a configuration, a user may check a state of laundry accommodated in the laundry accommodation unit through the window unit 11.
The display unit 12 displays (outputs) information processed by the laundry treating apparatus 1. For instance, the display unit 12 may display execution screen information about processes executed by the laundry treating apparatus 1 (a washing process, a dehydrating process, a drying process, etc.)· or User Interface (Ul) information and Graphic User Interface (GUI) information corresponding to the execution screen information.
The door 10 is installed by a hinge unit 30 (or a hinge module) so as to be rotatable with respect to the body 20. And the door 10 is configured to open and close the laundry introduction opening 20a.
In a state where the hinge unit 30 is mounted to one side of the door 10, a locking device for fixing the door 10 to the body 20 or for separating the door 10 from the body 20 is provided at another side of the door 10. The locking device is formed as a press-type. The door 10 may be locked when another side thereof is pressed once, and may be unlocked when the another side is pressed once more.
As shown, the body 20 may be provided with a door accommodation unit 20b inward-recessed from an outer surface of the body 20 and having the laundry introduction opening 20a therein. The door 10 may be accommodated in the door accommodation unit 20b in a closed state, and may be separated from the door accommodation unit 20b in an open state. With such a configuration, the door 10 is configured to open the laundry introduction opening 20a in an open state, and to block the laundry introduction opening 20a in a closed state.
Under the structure where the door 10 is accommodated in the door accommodation unit 20b, the hinge unit 30 may have a dual hinge structure having two different rotation shafts for instance, in order to prevent the door 10 from being locked by the body 20 when the door 10 is open. In this case, as shown in FIGS. 2A and 2B, the door 10 may be configured to be separated from the door accommodation unit 20b by a primary rotation about one of the two rotation shafts, and configured to rotate by a secondary rotation about another of the two rotation shafts.
Owing to such a dual hinge structure, a mechanism to open the laundry introduction opening as the door is rotated by more than 90°, may be implemented. The mechanism may be also applied even to a concaved-type door having a large size and having no gap between an outer surface of the door and a front surface of the body (i.e., a concaved-type door having its outer surface not protruding from the door accommodation unit).
Hereinafter, a detailed structure of the door 10 will be explained on the basis of such a dual hinge structure. FIG. 3A is an exploded perspective view of the laundry treating apparatus shown in FIG. 1, FIG. 3B is an exploded perspective view of a door shown in FIG. 1, and FIGS. 4Aand 4B are conceptual views illustrating a coupled state between a door and a hinge unit.
The laundry introduction opening is formed to have a circular shape, and the door 10 is also formed to have a circular shape (including a perfect circle and an oval shape) in correspondence to the laundry introduction opening. However, the present invention is not limited to this. That is, the laundry introduction opening and the door 10 may be formed to have a polygonal shape (a quadrangular shape, a hexagonal shape, etc.).
Referring to the drawings, the door 10 includes a door frame 110, a door window 120 and a door cover 140.
The door frame 110 is provided with an opening 110a which faces the laundry introduction opening 20a in a closed state of the door 10. The door window 120 is installed at the door frame 110 so as to correspond to the opening 110a. The door window 120 is formed of a transmissive material (glass, synthetic resin, etc.), and is disposed to correspond to the laundry introduction opening 20a in a closed state of the door 10.
As shown, the door frame 110 may include an outer frame 111 and an inner frame 112. The outer frame 111 and the inner frame 112 may be formed of a synthetic resin (e.g., an ABS material, a PC material, etc.).
The door window 120 is mounted to the door frame 110. The door window 120 is formed of a transmissive material (glass, synthetic resin, etc.), and is disposed to correspond to the laundry introduction opening 20a in a closed state of the door 10. The door cover 140 which forms appearance of the door 10 is coupled to the door frame 110. The door cover 140 may be formed of glass or a synthetic resin having a transmissive characteristic.
In this embodiment, the door frame 110 and the door cover 140 are formed to have a circular shape, in correspondence to the door 10 having a circular shape. As shown, the door frame 110 is rotatably coupled to the body 20, and the hinge unit 30 is coupled to each of the doorframe 110 and the body 20. In this case, the hinge unit 30 may be mounted to the body 20 from the upper side, on the basis of the center of the circular door 10. The door 10 may be rotatably connected to the hinge unit 30 at connection points (P1, P2) asymmetric to each other based on a horizontal center line (C1) of the door 10. And the hinge unit 30 may be disposed to be eccentric from a horizontal center line (C2) of the laundry introduction opening 20a. Referring to FIGS. 4A and 4B, both of the door 10 and the laundry introduction opening 20a are formed to have a circular shape. However, the door 10 and the laundry introduction opening 20a are formed to be eccentric from each other, since the display unit 12 is disposed at one side of the door 10. For a door opening structure in such an asymmetric structure, the hinge unit 30 is disposed on a position upward-eccentric based on the horizontal center line (C2) of the laundry introduction opening 20a, and has a specific structure. The door 10 may be rotatably connected to the hinge unit 30 at the connection points (P1, P2) asymmetric to each other based on the horizontal center line (C1) of the door 10, through a connection unit 33.
The connection unit 33 may be provided with an upper connection part 33a and a lower connection part 33b disposed at upper and lower sides based on the horizontal center line (C1) of the door 10. In this case, each of the upper connection part 33a and a lower connection part 33b may be provided with one or more connection portions. As shown, the upper connection part 33a and the lower connection part 33b may be disposed to be asymmetric to each other, based on the horizontal center line (C1) of the door 10.
The connection point P1 may be defined as an upper end of the upper connection part 33a, and the connection point P2 may be defined as a lower end of the lower connection part 33b. For instance, the connection point P1 may be a position of a bushing 334 to be explained later (refer to FIG. 5A) which is disposed at the upper end of the upper connection part 33a, and the connection point P2 may be a position of a bushing 334 to be explained later (refer to FIG. 5A) which is disposed at the lower end of the lower connection part 33b.
Alternatively, the connection point P1 may be defined as a central region (center) of the upper connection part 33a, and the connection point P2 may be defined as a central region (center) of the lower connection part 33b. In this case, the connection point P1 may be an intermediate region between bushings of the upper connection part 33a, and the connection point P2 may be an intermediate region between bushings of the lower connection part 33b.
More specifically, a distance (L1) from the horizontal center line (C1) of the door 10 to the upper connection part 33a may be longer than a distance (L2) from the horizontal center line (C1) of the door 10 to the lower connection part 33b. In this case, an intermediate region (C3) between the upper connection part 33a and the lower connection part 33b may be positioned above the horizontal center line (C1) of the door 10.
In the present invention, a door opening/closing structure suitable for a case where the circular door and the circular laundry introduction opening are eccentric from each other and the door is provided with the display unit, may be provided by arranging the hinge unit 30 on a position eccentric from the door 10.
In this case, a center of figure or a weight center of the hinge unit 30 may be eccentric based on the horizontal center line (C1) of the door 10, or the horizontal center line (C2) of the laundry introduction opening 20a.
The door accommodation unit 20b may be provided with through holes 23, and the hinge unit 30 may be blocked by the door accommodation unit 20b. And the connection unit 33 of the hinge unit may be exposed to the door accommodation unit 20b via the through holes 23. Like the connection unit 33, the through holes 23 of the door accommodation unit 20b may be asymmetric to each other up and down, based on the horizontal center line (C1) of the door 10. Accordingly, regions of the hinge unit 30, exposed to the door accommodation unit 20b via the through holes 23, may be asymmetric to each other based on the horizontal center line (C2) of the laundry introduction opening 20a. In this case, a center of the exposed regions may be disposed above the horizontal center line (C2) of the laundry introduction opening 20a.
With such an eccentric structure of the present invention, the hinge unit may enhance reliability at the time of supporting the door eccentric from the laundry introduction opening and having a greater weight at an upper part thereof.
The hinge unit having an eccentric structure may be applied to not only a single hinge structure, but also a dual hinge structure aforementioned in an embodiment of the present invention. A detailed structure of the hinge unit 30 will be explained later.
More specifically, a front cover 21 may be mounted to a front surface of the body 20, and the hinge unit 30 may be mounted to the inside of the body 20 to thus be connected to the door 10 through the front cover 21.
As shown, the door accommodation unit 20b aforementioned with reference to FIGS. 1 and 2 may be formed at the front cover 21 together with the laundry introduction opening 20a. The door 10 may be disposed so as to be accommodated in the door accommodation unit 20b, and such that an outer edge thereof may have the same plane as an outer surface of the body 20 adjacent to the door 10, in a closed state.
The through hole 23 may be formed on a side wall of the door accommodation unit 20b, the hinge unit 30 may be mounted to a hinge bracket (not shown) of the body 20, and at least part of the hinge unit 30 may be exposed to the door accommodation unit 20b via the through hole 23. The hinge bracket is configured to connect the laundry treating apparatus and the hinge unit 30 with each other. In this case, the hinge bracket may be disposed at an upper side on the basis of the center of the laundry introduction opening 20a. Accordingly, the hinge unit 30 may be disposed on a position eccentric from the laundry introduction opening 20a. As aforementioned with reference to FIGS. 1 and 2, the hinge unit 30 may have a dual hinge structure having two different rotation shafts, according to an embodiment. With such a structure, the door 10 is rotated by more than 90° to be separated from the door accommodation unit 20b. Hereinafter, the structure of the hinge unit 30 will be explained in more detail with reference to FIGS. 5A-5C and 6A-6D, together with FIGS. 1 and 2. FIG. 5A is an exploded perspective view of the hinge unit shown in FIG. 3A, FIG. 5B is a side sectional view of the hinge unit shown in FIG. 3A, FIG. 5C is a perspective view of the hinge unit shown in FIG. 3A, and FIGS. 6Ato 6D are views illustrating an operation to open the door by the hinge unit shown in FIG. 5A.
Referring to the drawings, the hinge unit 30 may be provided with a mounting portion 311 mounted to the body. And the mounting portion 311 may be formed such that a width (BW) of a lower end region thereof may be narrower than a width (TW) of an upper end region thereof. In this case, the width may mean a distance in right and left directions when the door is viewed from a front side. The mounting portion 311 may be formed such that a lower area thereof may be smaller than an upper area thereof based on the horizontal center line (C1) of the door 10. With such a configuration, a center of figure or a weight center of the mounting portion 311 is positioned above the horizontal center line (C1) of the door 10.
Furthermore, the mounting portion 311 may be formed such that a length from the horizontal center line (C1) of the door 10 to an upper end of the mounting portion 311 may be longer than a length from the horizontal center line (C1) of the door 10 to a lower end of the mounting portion 311. That is, the mounting portion 311 may be positioned to be biased based on the horizontal center line (C1) of the door 10.
The structure of the mounting portion 311 is related to the aforementioned hinge unit biased based on the horizontal center line (C1) of the door 10, and may be applicable to a dual hinge structure to be explained later.
More specifically, the hinge unit 30 may be provided with a base member 310 having the mounting portion 311.
The base member 310 may be formed of a metallic material having a strength high enough to support the door, and having durability large enough not to be transformed when the door is open and closed. More specifically, the base member 310 includes a protrusion portion 312 protruding from the mounting portion 311. For instance, a plurality of protrusions 313, 314 may protrude from the mounting portion 311, so as to be upper and lower asymmetric to each other based on the horizontal center line (C1) of the door 10.
The mounting portion 311 is mounted to the body of the laundry treating apparatus, e.g., the hinge bracket. Since the hinge unit 30 is disposed on a position eccentric from the laundry introduction opening 20a, the base member 310 may be mounted to the body (more specifically, the hinge bracket) so as to be upward-biased based on the horizontal center line (C1) of the door 10. In this case, the base member 310 may be mounted to the body in a state where an intermediate region between the plurality of protrusions 313, 314 is disposed above the horizontal center line (C2) of the laundry introduction opening 20a.
The mounting portion 311 may be formed as a plate member, and may be formed such that one edge thereof may have a circular arc in correspondence to the shape of the laundry introduction opening 20a. Since the base member 310 is positioned above the center of the circular laundry introduction opening 20a, the one edge may be formed along a circular arc positioned on the left upper side of the circular laundry introduction opening 20a.
The protrusion portion 312 may be configured as cantilevers protruding from the mounting portion 311. In this case, the protrusion portion 312 may protrude so as to form an obtuse angle with the mounting portion 311. For instance, the protrusion portion 312 extends in a diameter direction of the laundry introduction opening, and extends towards a front surface of the body 20. That is, the protrusion portion 312 extends towards a front surface of the body 20, in an inclined state from the mounting portion 311, thereby protruding to the door accommodation unit 20b via the through hole 23 of the front cover 21.
More specifically, the protrusion portion 312 may include a first protrusion 313 and a second protrusion 314 spaced from each other. As shown, the first protrusion 313 may be disposed above the horizontal center line (C1) of the door 10, and the second protrusion 314 may be disposed below the horizontal center line (C1) of the door 10. In this case, the first and second protrusions 313, 314 may be coupled to a first connection part to be explained later.
As aforementioned, the mounting portion 311 may be formed such that a width of a lower end region thereof may be narrower than a width of an upper end region thereof. The upper end region indicates a region close to an upper end of the mounting portion 311. In this embodiment, the upper end region may be formed between the first protrusion 313 and the upper end of the mounting portion 311. Likewise, the lower end region indicates a region close to a lower end of the mounting portion 311. In this embodiment, the lower end region may be formed between the second protrusion 314 and the lower end of the mounting portion 311.
In this case, both of the first and second protrusions 313, 314 may be disposed above a center of the laundry introduction opening 20a. The first protrusion 313 and the second protrusion 314 are spaced from each other on the mounting portion 311, and the mounting portion 311 may be formed such that its width may become narrower toward the second protrusion 314 from the first protrusion 313. For instance, a width of the mounting portion 311 corresponding to the first protrusion 313 is formed to be greater than a width of the mounting portion 311 corresponding to the second protrusion 314. More specifically, a width of the mounting portion 311 around the first protrusion 313 may be formed to be greater than a width of the mounting portion 311 around the second protrusion 314.
Since one edge of the mounting portion 311 forms a circular arc, another edge of the mounting portion 311 forms a straight line in upper and lower directions, for change of the width of the mounting portion 311. With such a configuration, the width of the mounting portion 311 may become narrower toward the center of the laundry introduction opening 20a from the upper side.
The mounting portion 311 may be formed such that its surface mounted to the body may be inclined. For instance, at least part of the mounting portion 311 may be inclined from a rotation shaft of the connection unit 33, such that the lower end region of the mounting portion 311 is closer to the connection unit than the upper end region of the mounting portion 311. That is, the connection unit 33 is disposed in a vertical direction, and the mounting portion 311 is formed to be inclined from the vertical direction by a preset angle (Θ). As shown, all of the upper end region, the lower end region, and a region between the first and second protrusions may be formed to be inclined. And part of the mounting portion 311 to be mounted to the body may be formed to be inclined.
An insertion hole 315 for inserting a hinge shaft may be formed at the end of each of the first protrusion 313 and the second protrusion 314. The hinge shaft is disposed on a fixed position with respect to the body 20, and forms one of two rotation shafts by a dual hinge structure. Thus, the hinge shaft may be referred to as a first rotation shaft 321.
As shown, the hinge unit 30 is provided with a connection member 330, and the connection member 330 is rotatably connected to the protrusion portion 312. The connection member 330 may be rotatably connected to the protrusion portion 312 such that a rotation center of the door may be moveable.
In this case, the first rotation shaft 321 may be a fixed shaft to which the connection member 330 is rotatably connected. The connection member 330 is configured to move a rotation center of the door 10 between a closed state and an open state of the door 10. For instance, a first connection part 331 of the connection member 330 may be connected to the base member 310, and the door may be rotatably connected to a second connection part 332 of the connection member 330.
In a dual hinge structure, the first connection part 331 may be formed at one end of the connection member 330, and the first connection part 331 may be rotatably connected to the base member 310 through the first rotation shaft 321. Alternatively, the first connection part 331 may slidably-connect the connection member 330 to the base member 310. In this case, the connection member 330 rather than the first rotation shaft is slidably-coupled to the protrusion portion of the base member 310. The first connection part 331 may be moveably-coupled to the base member 310.
The second connection part 332 may be formed at another end of the connection member 330, such that a rotation center of the door 10 may be moveable between a closed state and an open state of the door 10. And the door 10 may be rotatably connected to the second connection part 332.
As shown, a second rotation shaft 322 is mounted to the second connection part 332, and the rotation center of the door 10 is moved from the first connection part (or the first rotation shaft) to the second connection part (or the second rotation shaft). A bushing 334 may be mounted to the second rotation shaft 322, and a hinge holder 351 (refer to FIG. 3A) for coupling with the door 10 is coupled to the bushing 334. The hinge holder 351 may be coupled to the door 10, and a holder cover 352 configured to cover the hinge holder 351 may be mounted to the door 10.
The connection member 330 may include a first member 335 extending to one direction, and a second member 336 protruding from the end of the first member and extending toward another direction different from the one direction. In this case, the first rotation shaft 321 may be connected to one end of the first member 335, and the second member 336 may be bent from another end of the first member 335 toward said another direction. The second rotation shaft 322 is mounted to the end of the second member 336, and the door is rotatably coupled to the second rotation shaft 322.
In this case, the first member 335 is formed as a straight bar, and the second member 336 is formed as a curved bar. More specifically, the second member 336 forms a circular arc having the first connection part 331 as its center. Accordingly, the second member 336 may extend in a circumferential direction having the first connection part 331 as the center.
The hinge unit 30 is formed to accommodate therein at least part of an electric wire 50 for electrically connecting the display unit 12 (refer to FIG. 1) to a controller (a main printed circuit board) provided at the body. For instance, an accommodation space configured to accommodate the electric wire 50 therein may be formed on at least part of the hinge unit. The accommodation space may form an accommodation groove 337. More specifically, the accommodation groove 337 may be provided at the connection member 330. For instance, the accommodation groove 337 configured to accommodate the electric wire 50 therein may be formed at the second member 336, and a cover 338 configured to cover the accommodation groove 337 may be mounted to the hinge unit 30. In this case, an opening 339 of the accommodation groove 337 may be disposed at the second connection part 332. As shown, the opening 339 is positioned at one end of the second connection part 332, and the electric wire 50 may extend to the body via the opening 339 and the accommodation groove 337.
The accommodation groove 337 may extend towards the first member 335, and the electric wire 50 may be connected to the inside of the laundry treating apparatus via the first connection part 331. The electrical wire 50 may serve as a path for electrically connecting the door to the controller inside the laundry treating apparatus.
The connection member 330 may be provided with an upper connection member 330b and a lower connection member 330a asymmetric to each other based on the horizontal center line of the door. The electric wire may be connected to the body through the upper connection member 330b. That is, the accommodation groove 337 configured to accommodate the electric wire 50 therein may be formed at the upper connection member 330b. More specifically, the second member 336 may be provided with an upper member and a lower member disposed at upper and lower sides based on the horizontal center line of the door, and the accommodation space (e. g, the accommodation groove 337) may be formed at the upper member. With such a configuration, a path of the electric wire 50 for connecting the inside of the laundry treating apparatus to the outside may be easily obtained.
The dual hinge structure will be explained again. The first member 335 protrudes from the first connection part 331, toward a direction which becomes closer to a rear surface of the door 10, in a closed state of the door. On the contrary, the second member 336 may protrude from the end of the first member 335, toward a direction which becomes closer to a front surface of the door 10, in a closed state of the door.
The first member 335 and the second member 336 may be disposed to have an acute angle therebetween. In this case, the second member 336 may be formed to cross the protrusion. With such a configuration, one side of the second member 336, close to the first connection part 331, may be disposed on the right side of the first connection part 331 at the door.
The connection member 330 having the aforementioned structure may be formed to be rotated about the first connection part 331 within a preset range, as the door is rotated from a closed state (refer to FIG. 6A). In this case, the first connection part 331 may be formed such that the connection member 330 may be rotated about the first rotation shaft 321 up to a preset angle.
Referring to FIGS. 6A to 6C, at least part of the connection member 330 is formed to pass through at least part of the base member within the preset range, as the door is rotated. For instance, the second member 336 and the first member 335 are sequentially rotated via the protrusion.
Once the second member 336 and the first member 335 are sequentially rotated via the protrusion, the door is open up to a limit of the preset range (in this embodiment, 75°) (refer to FIG. 6C, this open state will be called an ‘ intermediate open state’). A stopper (not shown), configured to restrict the connection member from being rotated to a door opening direction at the limit, may be provided at the first connection member 331. As shown, in the intermediate open state, the door 10 partially covers the laundry introduction opening 20a at the front side.
In this case, the second rotation shaft 322 is rotated about the first rotation shaft 321 up to the preset angle, as the door 10 is rotated in the intermediate open state. As a result, the second rotation shaft 322 is moved toward a direction which becomes farther from the laundry introduction opening 20a.
If the door 10 is continuously rotated about the first rotation shaft 321 in the intermediate open state, one side of the door may be locked by the front cover 21, because there is no gap between the front cover 21 and an outer surface of the door 10. In this embodiment, the dual hinge structure makes a rotation center of the door 10 move to the second connection part 332 from the first connection part 331, in the intermediate open state.
For instance, the rotation of the door 10 about the first rotation shaft 321 is restricted in the intermediate open state. Accordingly, if an external force is applied to the door 10, the door 10 is rotated about the second rotation shaft 322 as shown in FIG. 6D. For instance, if the rotation of the door 10 about the second rotation shaft 322 is executable up to a specific angle (in this embodiment, 45°), the door 10 is further rotated by the specific angle in the intermediate open state.
As a result, the door 10 opens the laundry introduction opening up to an open state (a state where the laundry introduction opening is not blocked when viewed from the front side).
So far, the dual hinge structure has been explained on the basis of an operation to open the door 10. An operation to close the door 10 may be performed in a reverse manner to the aforementioned method. For instance, if an external force is applied to the door 10 in an open state toward a door closing direction, the door 10 is rotated about the second rotation shaft 322 up to the intermediate open state. If the external force is continuously applied, the connection member 330 is rotated about the first rotation shaft 321 together with the door 10, from the intermediate open state to a closed state. As a result, the connection member 330 is accommodated in the door accommodation unit 20b.
The aforementioned structure and operation may provide a laundry treating apparatus capable of opening and closing a laundry introduction opening, even in case of a concaved-type door not protruding from a body.
The aforementioned hinge unit may be modified in various manners. Such modification examples will be explained in more detail with reference to the drawings. FIG. 7 is an exploded perspective view of a hinge unit according to another embodiment of the present invention, and FIGS. 8Ato 8D are views illustrating an operation to open the door by the hinge unit shown in FIG. 7.
Like the hinge unit aforementioned with reference to FIG. 5, the hinge unit in this embodiment includes a base member 310, a connection member 330, a first rotation shaft 321, and a second rotation shaft 322. Explanations about a structure of the components will be replaced by the aforementioned ones. For instance, the base member 310 may be provided with a mounting portion 311 and a protrusion portion 312a, and the connection member 330 may be provided with a first member 335 and a second member 336. The first rotation shaft 321 may form a first connection part 331, and the second rotation shaft 322 may form a second connection part 332. The protrusion portion 312a may be provided with a first protrusion 313 and a second protrusion 314a. As the door is rotated to an open state from a closed state, its rotation center is moved to the second rotation shaft 322 from the first rotation shaft 321.
As shown, the hinge unit may further include a rotation guide unit 340. Since each of the first member 335 and the second member 336 extends in the form of a bar, a large bending moment may occur on the first connection part 331 due to a weight of the door 10. Thus, the rotation guide unit 340 may be formed to reinforce the first connection part 331.
For instance, a guide groove 341 may be formed at the protrusion portion 312a, more specifically, at the second protrusion 314a. For this, the second protrusion 314a may be formed to have a larger area than the second protrusion 314 of the base member 310 aforementioned with reference to FIG. 5. As shown, a guide protrusion 342 inserted into the guide groove 341 may be disposed at a connection part between the first member 335 and the second member 336. The guide groove 341 may be formed to have a circular arc having the first rotation shaft 321 as its center. In this case, the connection member 330 is rotated until the guide protrusion 342 is positioned at the end of the guide groove 341. Thus, the guide groove 341 serves as a stopper, and determines a rotated degree of the connection member 330.
With such a configuration, as shown in FIGS. 8A to 8D, the guide protrusion 342 is rotated about the first rotation shaft 321, while being moved along the guide groove 341.
With such a structure, when the door is rotated between a closed state and an intermediate open state, the rotation of the door is guided by the rotation guide unit 340. Further, a bending moment applied to the first connection part 331 is distributed. This may allow the laundry treating apparatus to have an enhanced reliability in opening and closing the concaved-type door, with a more compact hinge structure.
As another modification example of the hinge unit, the electric wire of the display unit may be connected to the controller by the hinge unit, even in a single hinge structure. FIG. 9A is a conceptual view illustrating still another embodiment of the present invention, and FIG. 9B is a perspective view of a hinge unit shown in FIG. 9A.
As shown, in a single hinge structure, the electric wire 50, configured to connect the display unit 12 (refer to FIG. 1) to the controller, is connected from the door 10 to the body 20 (refer to FIG. 1) of the laundry treating apparatus through the hinge unit. For instance, the hinge unit may be provided with a mounting portion 411 and a protrusion portion 412. And the electric wire 50 may be connected from the door to the body through the protrusion portion 412.
In this embodiment, the mounting portion 411, part mounted to the body of the laundry treating apparatus, is formed as a plate member. The mounting portion 411 may be formed such that a width of a lower end region thereof may be narrower than a width of an upper end region thereof. In this case, the mounting portion 411 may be formed such that a lower area thereof may be smaller than an upper area thereof based on the horizontal center line (C1) of the door.
The protrusion portion 412 may be provided with a plurality of protrusions 413, 414 protruded from the mounting portion 411, and the plurality of protrusions 413, 414 may be disposed to be asymmetric to each other up and down based on the horizontal center line (C1) of the door. The door may be rotatably connected to the protrusion portion 412, and a connection unit 432 may be formed at the end of the protrusion portion 412.
The door accommodation unit 20b may be provided with through holes 23, and the hinge unit may be blocked by the door accommodation unit 20b. And protrusion portion 412 and the connection unit 432 may be exposed to the door accommodation unit 20b via the through holes 23.
More specifically, the protrusion portion 412 may be provided with an upper protrusion 413 and a lower protrusion 414 asymmetric to each other up and down based on the horizontal center line (C1) of the door. And the electric wire 50 is connected to the body through the upper protrusion 413. For instance, an accommodation space configured to accommodate the electric wire 50 therein (e.g., an a accommodation groove 437) may be formed at the upper protrusion 413. And a cover (not shown) configured to cover the accommodation groove 437 may be mounted to the hinge unit.
Since the door is rotatably coupled to one end of the protrusion portion 412, the protrusion portion 412 may be a structure of the connection member 330 and the protrusion portion 312 (refer to FIG. 5A) aforementioned in a dual hinge structure. In this embodiment, a region of the hinge unit, exposed to the door accommodation unit via the through holes 23, may be part of the protrusion portion 412 and the connection unit 432. Accordingly, the part of the protrusion portion 412 and the connection unit 432 may be disposed to be asymmetric to each other based on the horizontal center line (C1) of the door. Like the connection unit 432, the through holes 23 of the door accommodation unit 20b may be asymmetric to each other up and down, based on the horizontal center line (C1) of the door 10.
More specifically, the connection unit 432 may be provided with an upper connection part 432a and a lower connection part 432b disposed at upper and lower sides based on the horizontal center line (C1) of the door. In this case, each of the upper connection part 432a and the lower connection part 432b may be provided with one or more connection portions. As shown, the upper connection part 432a and the lower connection part 432b may be disposed to be asymmetric to each other, based on the horizontal center line (C1) of the door.
As shown, a bushing 434 may be mounted to each of the upper connection part 432a and the lower connection part 432b.
In this case, an opening 439 of the accommodation groove 437 may be disposed at the upper connection part 432a. As shown, the opening 439 may be positioned at the end of the upper connection part 432a where the bushing 434 is mounted, and the electric wire 50 may extend to the body via the opening 439 and the accommodation groove 437. The accommodation groove 437 may extend to the inside of the body along the protrusion portion 412. Accordingly, the electrical wire 50 may be connected to the inside of the laundry treating apparatus.
With such a configuration, even in a single hinge structure, the electric wire configured to connect the display unit to the controller may be implemented through the hinge unit.As the present features may be embodied in several forms without departing from the characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its scope as defined in the appended claims, and therefore all changes and modifications that fall within the metes and bounds of the claims, or equivalents of such metes and bounds are therefore intended to be embraced by the appended claims.
