LAUNDRY TREATING APPARATUS TECHNICAL FIELD

[0001] A laundry treating apparatus capable of preventing a door from being lifted

is disclosed herein.

BACKGROUND

[0002] In general, a laundry treating apparatus may include an apparatus having

a function of washing or drying laundry or other items (hereinafter, collectively

"laundry"). In addition, the laundry treating apparatus may be configured to have both a

washing function and a drying function of the laundry.

[0003] Laundry treating apparatuses may be classified according to a laundry

loading method, into a front-load type (also called "drum-type washer") in which the

laundry is loaded through a front surface of a main body, and a top-load type (also

called "top-load washer") in which the laundry is loaded through a top surface of a main

body.

[0004] A laundry treating apparatus may include a main body having a laundry

inlet port formed through a front surface, a tub provided inside of the main body to store

wash water therein, a drum rotatably provided in the tub, and a door installed on the

main body to open and close the laundry inlet port. The door may be provided with a

door frame, and a door window provided on the door frame to view inside of the drum. A

front portion of the door frame may protrude outward from a recess, and a rear portion

of the door frame may be accommodated in the recess. The door window may protrude

from a rear surface of the door frame into the drum through the laundry inlet port.

87285939.3

[0005] However, the related art drum type laundry treating apparatus has the

following problems.

[0006] When a large amount of clothes is put into the drum, the clothes soaked

with water repeatedly hit a lower portion of the door window, which protrudes into the

drum, as the clothes spin together with the drum. For this reason, a lower side of the

door is pushed forward and an upper side of the door is in contact with the recess of the

main body to periodically apply an impact to the main body, thereby causing vibration

and noise in the main body.

[0007] A drum type washing machine is disclosed in Korean Laid-Open Patent

Publication No. KR 10-2011-0028899A, published on March 22, 2011 and hereinafter,

referred to as "Patent Document 1", which is hereby incorporated by reference. In the

washing machine disclosed in Patent Document 1, a support unit is installed on a rear

surface of a door. When the door opens and closes a laundry inlet port, the support unit

maintains a predetermined distance between the door and a main body.

[0008] More specifically, the support unit is brought into contact with a flat surface

of a recess recessed into a front surface of the main body, such that the predetermined

distance between the door and the main body is maintained. Accordingly, a ventilation

gap is formed between the door and the main body. The support unit serves to ventilate

an inner space of the main body and outside through the ventilation gap (see FIG. 4A of

Patent Document 1). The support unit contacts the flat surface of the recess of the main

body when the door is opened and closed, thereby alleviating an impact transferred to

the main body through the door.

[0009] However, Patent Document 1 has the following problems.

87285939.3

[0010] First, as the support unit has a structure protruding separately from a rear

surface of a door frame, an appearance of the door is spoiled. In particular, as the door

frame protrudes outward from the recess of the main body and is spaced apart from the

recess with the ventilation gap therebetween, the protruding structure of the door is

exposed to outside through the ventilation gap even when the door is closed, thereby

degrading an appearance quality of the door.

[0011] In addition, the support unit protrudes so as to contact the flat surface

inside of the recess. This causes an increase in size of the support unit and adversely

affects appearance quality.

[0012] Second, if a separate buffer member or elastic member for mitigating an

impact is provided between the door and the main body in order to solve the problem of

vibration and noise caused between the door and the main body, an installation space

for the buffer member is needed between the door and the main body, which further

increases a gap between the door and the main body due to a thickness of the buffer

member. In addition, when wear or failure of the buffer member occurs due to friction

between the buffer member and the main body, the buffer member should be replaced,

causing user inconvenience.

[0013] Third, the support unit includes a support body and a magnet provided

inside of the support body, so that the support body is coupled to the main body by

magnetic force. As a result, the user must pull the door harder to open the door

because of the attraction force of the magnet.

[0014] Korean Laid-Open Patent Publication No. 10-2010-0042984 A, published

on April 27, 2010 and hereafter, referred to as "Patent Document 2", discloses a drum

87285939.3 type washing machine. According to the disclosure of Patent Document 2, an elastic member is provided on a rear surface of a door (see FIG. 3 of Patent Document 2). The elastic member may alleviate an impact by elastically compressing the door in a closing process.

[0015] However, Patent Document 2 has the following problems.

[0016] First, as the separate elastic member protrudes from a rear surface of a

door frame, an appearance of the door is spoiled.

[0017] Second, when the elastic member has a protruding structure made of a

rubber material, problems, such as wear, for example, are caused.

[0018] Third, when the elastic member is made of a combination of a coil spring

and a cap member, its structure becomes complicated and fabricating costs increase.

[0019] It is desired to address or ameliorate one or more disadvantages or

limitations associated with the prior art, provide a laundry treating apparatus, or to at

least provide the public with a useful alternative.

[0102] A circular opening 18 may be formed in each of the outer frame 14 and

the inner frame 19. The openings 18 may be eccentrically positioned from centers of the

outer frame 14 and the inner frame 19, respectively. For example, a center of the

opening 18 may be positioned above a center of each of the outer frame 14 and the

inner frame 19.

[0103] According to this embodiment, each of the outer frame 14 and the inner

frame 19 may vary in width along a circumferential direction. In other words, a distance

(width) between an outer diameter and an inner diameter (a diameter of the opening 18)

of each of the outer frame 14 and the inner frame 19 may increase (widen) from a top

end to a bottom end.

[0104] A center of the drum may be disposed higher than a center of a height

(1/2) of the main body 10. The drum may be fixed in a heightwise direction of the main

body 10 aside from minute vibration due to rotation.

[0105] Consumers tend to prefer a larger size of the door 12 with respect to a

same capacity and size of washing machine when looking at the main body 10 from the

front. In addition, consumers are able to look into the drum through the door 12, and if

possible, prefer a wide field of view with regard to an inner space of the drum.

[0106] In order to satisfy the needs of consumers, the door 12 must be enlarged

downward to increase the size of the door 12 while a position of the drum is fixed. A

center of the door frame 13 must move below a center of the laundry inlet port 102 or

the opening 18. Similarly, the center of the door frame 13 may move downward with

respect to the door window 23 positioned to correspond to the opening 18. In addition,

87285939.3 in order to increase the size of the door 12, a portion of the door 12 that protrudes outward from a recess 103 and the door 12 may have a larger diameter.

[0107] The front glass 20 may have in a circular shape. The front glass 20 may

be made of a glass material. The front glass 20 may have flat front and rear surfaces.

The front glass 20 may have in a disc shape having a constant thickness, without

bending when viewed from any direction, up, down, left, or right.

[0108] As described above, the front and rear surfaces of the front glass 20 made

of the glass material may be formed flat in the circular shape, thereby enhancing a

quality grade of the door 12, compared to a door cover in the related art made of a

synthetic resin material that has a convex front surface in an incomplete circular shape.

[0109] The front glass 20 may cover the opening 18 of the door frame 13. The

front glass 20 may be bonded to a front surface of the outer frame 14 by a sealant or an

adhesive.

[0110] Due to a nature of the glass material, the front glass 20 may be easily

broken when a coupling hole is drilled in the front glass 20. Thus, the front glass 20 may

be attached to the outer frame 14 using an adhesive, for example, to prevent the glass

from being broken.

[0111] On the other hand, the front glass 20 made of the glass material occupies

a relatively large load compared to a total load of the door 12. In order to support the

load of the front glass 20, a mounting guide 34 to mount the front glass 20 may be

provided on a front surface of the outer frame 14.

[0112] In particular, the front glass 20 may be made of tempered glass. Due to a

nature of the tempered glass, the front and rear surfaces of the front glass 20 have a

87285939.3 high strength, but a circular outer circumferential surface, which is a side surface of the front glass 20, has a low strength.

[0113] To compensate for this, the mounting guide 34 may protrude forward from

a front outer circumferential end of the outer frame 14 to surround the outer

circumferential surface of the front glass 20, so as to support the load of the front glass

20 as well as to protect the outer circumferential surface of the front glass 20 from

external impact.

[0114] A protruding length of the mounting guide 34 may cover at least 2/3 of a

thickness of the front glass 20. This is because an external impact may be applied to

the outer circumferential surface of the front glass 20 and the load of the front glass 20

may not be sufficiently supported when the protruding length of the mounting guide 34

is too short.

[0115] For example, a straight portion 202 and a plurality of curved portions 201,

203 may be formed on a side surface in a radial direction at the outer circumferential

surface of the front glass 20. The plurality of curved portions 201, 203 may include first

curved portion 201 connected to the front surface of the front glass 20 and second

curved portion 203 connected to the rear surface of the front glass 20. The straight

portion 202 may extend between the first and second curved portions 201, 203 and be

connected to the first and second curved portions 201, 203, respectively. Each of the

first curved portion 201, the straight portion 202, and the second curved portion 203

may be 1/3 of the thickness of the front glass 20.

[0116] The mounting guide 34 may cover the second curved portion 203 and the

straight portion 202 of the front glass 20. The mounting guide 34 may protrude from a

87285939.3 front edge portion or edge of the outer frame 14. The mounting guide 34 may be formed in a ring shape to define a space in which the front glass 20 may be accommodated.

[0117] The mounting guide 34 may have a predetermined inner diameter to

define a circle. The inner diameter of the mounting guide 34 may correspond to an outer

diameter of the front glass 20, and thus, the mounting guide 34 may be configured to

surround the outer circumferential surface of the front glass 20.

[0118] A transparent region 21 and a non-transparent region 22 may be disposed

at inner and outer sides of the front glass 20, respectively. The transparent region 21

denotes a region configured to transmit at least portion of light so that an opposite side

or the inside may be viewed. Therefore, the transparent region 21 may be a translucent

region 21.

[0119] The transparent region 21 may correspond to the opening 18 of the outer

frame 14, the opening 18 of the inner frame 19, and the door window 23. Therefore,

while the door 12 is closed, the user may look into the laundry accommodating portion

through the transparent region 21.

[0120] A center of the transparent region 21 may be located at a position

corresponding to a center of the opening 18 of each of the outer frame 14 and the inner

frame 19. The corresponding position may include not only perfect alignment of the

center, but also the same in an eccentric direction of the center. In other words, the

center of the transparent region 21 and the center of the opening 18 may coincide with

each other, or the eccentric direction of the transparent region 21 may be the same as

the eccentric direction of the opening 18.

87285939.3

[0121] In embodiments disclosed herein, the center of the opening 18 is

eccentrically located from the center of the door frame 13 to an upper side (12 o'clock

direction), and correspondingly, the center of the transparent region 21 is also

eccentrically located from the center of the front glass 20 to the upper side (12 o'clock

direction). The center of the transparent region 21 and the center of the opening 18 may

alternatively coincide with each other.

[0122] The non-transparent region 22 may surround the transparent region 21.

Also, the non-transparent region 22 does not transmit light therethrough, and thus, the

glass itself may appear black in the non-transparent region 22.

[0123] The non-transparent region 22 may cover the remaining portion except for

the opening 18 and a portion of the door frame 13. A boundary line between the

transparent region 21 and the non-transparent region 22 surrounding the transparent

region 21 may be clearly distinguished by the non-transparent region 22.

[0124] Alternatively, the boundary between the transparent region 21 and the

non-transparent region 22 may be blurred through a halftone technique, thereby

allowing a visual transition from the transparent region 21 to the non-transparent region

22. The non-transparent region 22 may include a plurality of shielding dots arranged

around the transparent region 21, and the plurality of shielding dots may be arranged to

have a lower density toward the transparent region 21.

[0125] The outer frame 14 may include a flat portion 15 and a curved portion 16.

The flat portion 15 may be in contact with the rear surface of the front glass 20, and a

portion of the flat portion 15 may overlap the non-transparent region 22. An adhesive

87285939.3 may be applied to the flat portion 15 so that the front glass 20 may be adhered to the flat portion 15.

[0126] An adhesive groove 37 may be formed concave in a ring shape in a front

surface of the flat portion 15 facing the front glass 20, so that adhesive may be filled

therein. The rear surface of the front glass 20 may be adhered to the flat portion 15 by

the adhesive.

[0127] The adhesive may overflow to an outside or an inside of the adhesive

groove 37 when the adhesive is filled in the adhesive groove 37. In order to

accommodate adhesive overflowing from the adhesive groove 37, adhesive overflow

grooves 38 may be formed in a ring shape at an inside and an outside of the adhesive

groove 37, respectively.

[0128] The adhesive groove 37 and the adhesive overflow grooves 38 may be

formed at an outer side of the flat portion 15. The non-transparent region 22 of the front

glass 20 may cover the adhesive groove 37 and the adhesive overflow grooves 38.

[0129] A plurality of drain holes 39 may be formed through a lower side of the flat

portion 15 in a thickness direction of the flat portion 15. Accordingly, water or moisture

(liquid) generated between the rear surface of the front glass 20 and a front surface of

the outer frame 14 may be discharged outside through the plurality of drain holes 39.

[0130] The curved portion 16 may be curved in an arc shape having a

predetermined curvature toward an outer circumference of the opening 18 formed in the

inner frame 19 from an inner end of the flat portion 15. An inner portion of the flat

portion 15 and the curved portion 16 may overlap an outer edge portion or edge of the

87285939.3 transparent region 21. The opening 18 may be located at an inner side of the curved portion 16 in a radial direction.

[0131] The mounting guide 34 may be formed on an outermost portion of the flat

portion 15 in the circumferential direction to protrude more than the flat portion 15. The

mounting guide 34 of the outer frame 14 may surround an outer edge of the front glass

20, thereby preventing the outer edge of the front glass 20 from be released radially

outward from the flat portion 15 of the outer frame 14.

[0132] A protection layer 17 may be disposed on front and outer circumferential

surfaces of the outer frame 14 by chromium plating, for example. The outer frame 14

may be completely immersed in a chromium plating solution, followed by the chromium

plating, so that the protection layer 17 may be formed on an entire surface of the outer

frame 14. Also, the outer frame 19 may be completely immersed in a chromium plating

solution, followed by the chromium plating, so that the protection layer 17 may be

formed on an entire surface of the inner frame 19.

[0133] The protection layer 17 may coat the outer frame 14 with a silver polished

metal color. Accordingly, the protection layer 17 may obtain an effect that it looks like

bright silver circular droplets. In addition, the protection layer 17 may cause a sense of a

high quality when viewed with the naked eye.

[0134] The door window 23 may be disposed to correspond to the laundry inlet

port 106 while the door 12 is closed. The door window 23 may be mounted to the door

frame 13 to correspond to the opening 18 of the inner frame 19.

[0135] The door window 23 may be made of a transparent material, for example,

a synthetic resin material having a light transmitting property, so that an inner space of

87285939.3 the laundry accommodating portion, such as the drum, may be viewed through the door window 23. The door window 23 may not be necessarily limited to such synthetic material but may alternatively be made of a glass material. An outer edge portion or edge 231 of the door window 23 may be inserted and coupled between the outer frame

14 and the inner frame 19.

[0136] The outer edge portion 231 of the door window 23 may have a flat shape,

and may be fixedly disposed between a rear end of the curved portion 16 of the outer

frame 14 and an inner end of the inner frame 19. The door 12 may be rotatably provided

in a frontward-rearward direction with respect to the main body 10 by the hinge unit 24.

[0137] The hinge unit 24 may include a hinge 25, a hinge holder 28, and a bush

29. The hinge 25 may be fixed to the main body 10, and rotatably coupled to the door

frame 13. The hinge 25 may include a plate-shaped base 26 coupled to the main body

10, and a rotation coupling portion 27 that protrudes from the base 26 and is rotatably

coupled to the door frame 13. A plurality of rotation coupling portions 27 may be

provided and spaced apart in a vertical direction.

[0138] The hinge holder 28 may be coupled to the door frame 13 to support the

plurality of rotation coupling portions 27 to prevent the plurality of rotation coupling

portions 27 from being released from the door frame 13. The bush 29 may be inserted

onto a rotational shaft of the rotary coupling portion 27 to efficiently rotate the rotational

shaft.

[0139] The hinge unit 24 may be mounted at one or a first side of the door 12,

and the locking unit 30 may be provided at the other or a second side of the door 12.

The locking unit 30 is configured to lock or unlock the door 12 to the body 10.

87285939.3

[0140] The locking unit 30 may include a shaft 31, a door latch 32, and a spring

33. The shaft 31 may pass through the door latch 32, and be mounted on the door

frame 13. The spring 33 has an elastic force to be retractable during rotation of the door

latch 32. According to this embodiment, the door latch 32 may be configured to be

rotatable and restorable to the door frame 13 so as to lock or unlock the door 12 to the

main body 10.

[0141] FIG. 4 is a cross-sectional view, taken along the IV-IV in FIG. 1, illustrating

a state in which the door 12 is mounted on the front panel 101 of the main body 10 to

close the laundry inlet port 106. FIG. 5 is a rear view of the door in FIG. 2. FIG. 6 is a

front view illustrating a state in which the recess 103 is recessed in the front panel 101

to surround the laundry inlet port 106 in FIG. 4. FIG. 7 is an enlarged cross-sectional

view of portion "VII" in FIG. 4, illustrating that a contact portion 191 is in contact with the

recess 103 of the main body. FIG. 8 is an enlarged cross-sectional view of portion "VIII"

in FIG. 4, illustrating a state in which a non-contact portion 192 is spaced apart from the

recess 103 of the main body 10.

[0142] FIG. 4 illustrates a state in which the controller 11 of FIG. 1 is removed

from the upper side of the front panel 101. A plurality of ribs 102 may protrude upward

from an upper end portion or end of the front panel 101. The controller 11 may be

mounted on the upper end portion or end of the front panel 101. A rear surface of the

controller 11 and the plurality of ribs 102 may be coupled by coupling elements, such as

screws, for example.

[0143] Referring to FIGS. 4 and 5, a handle 35 may be formed by recessing a

rear upper side of the inner frame 19, so that the user may open the door 12 by pulling

87285939.3 the handle 35. The rear surface of the inner frame 19 may be convex rearward in an arcuate shape.

[0144] The handle 35 may be provided on the door 12 for the user to open and

close the door 12. In the related art, the handle is generally provided at a front side of

the door. However, in embodiments disclosed herein, as the front glass 20 is provided

to cover a front surface of the door 12, it is difficult to provide the handle 35 on the front

glass 20. Thus, the handle 35 is not provided on the front surface of the door 12 due to

the front glass 20, but rather, may be provided on a rear surface of the door 12. The

handle 35 may be provided on the inner frame 19.

[0145] In addition, the handle 35 may be provided at an upper portion of the door

12 for the user to easily pull the door 12. When the handle 35 is provided at a lower

portion of the door 12, the user has to bend his or her waist and knees more to pull the

handle 35.

[0146] Moreover, as the hinge unit 24 and the locking unit 30 are respectively

provided at lateral sides of the door frame 13, respectively, along a horizontal center

line CL-CL that horizontally passes through the center of the door frame 13 in the radial

direction, they may be positioned higher than the horizontal center line. In addition, the

handle 35 may be disposed on the upper side of the door frame 13 to be higher than the

locking unit 30 in order to open and close the door 12 with less force.

[0147] The handle 35 may be disposed on the upper side of the rear surface of

the inner frame 19. More specifically, when the door 12 is closed, the handle 35 may be

located at a right upper portion, namely, between one o'clock and three o'clock, when

viewed from the front of the main body 10.

87285939.3

[0148] The handle 35 may be recessed into the convex rear surface of the inner

frame 19 toward the outer frame 14. The handle 35 may have an arcuate shape on the

rear surface of the inner frame 19 along a partial section of the rear surface in the

circumferential direction.

[0149] The handle 35 may be formed thin and flat compared to an outer

circumference of the inner frame 19 (a portion of the inner frame 19 except for the

handle 35). Accordingly, when the door 12 is closed by the user, the handle 35 is

recessed forward in the flat shape, compared with the outer circumference on the rear

surface of the inner frame 19, when viewed from the front of the main body 10, thereby

facilitating insertion of the user's hand into the handle 35 as well as facilitating

identification of a position of the handle 35 in the closed state of the door 12.

[0150] Referring to FIGS. 4 and 6, the recess 103 may be provided on the front

panel 101 of the main body 10. The recess 103 may accommodate a portion of the door

12, particularly, a portion of the door frame 13, more particularly, a portion of the inner

frame 19.

[0151] The recess 103 may include a recessed portion 1031, and a flat portion

1032. The recessed portion 1031 may be recessed rearward into the front surface of

the front panel 101 toward the inside of the main body 10. The recessed portion 1031

may have a larger diameter than the laundry inlet port 106 and may be formed in a

curved shape along the circumferential direction.

[0152] The recessed portion 1031 may be formed in a circular shape to surround

an outer circumference of the flat portion 1032. Both sides of the recessed portion 1031

may be connected to the front surface of the front panel 101 and the flat portion 1032,

87285939.3 so that the flat portion 1032 is stepped toward the inside of the main body 10 with respect to the front surface of the front panel 101. The recessed portion 1031 may be bent backward from the front surface of the front panel 101.

[0153] The recessed portion 1031 may be inclined while its diameter gradually

decreases from a front end to a rear end thereof. The flat portion 1032 may be disposed

toward the inside of the main body more rearward than the front surface of the front

panel 101.

[0154] The flat portion 1032 may extend perpendicularly in the form of a flat plate,

and the laundry inlet port 106 may penetrate through the inside of the flat portion 1032

in a thickness direction. The flat portion 1032 may have a ring shape.

[0155] The laundry inlet port 106 may be formed eccentrically from the center of

the recess 103. For example, a center of the laundry inlet port 106 may be located

higher than a center of the recess 103. As a result, a width (a radial distance) of the flat

portion 1032 becomes wider (longer) from an upper portion to a lower portion of the flat

portion 1032.

[0156] A hinge portion 104 to couple with the hinge unit 24 may be provided at a

left or first side of the flat portion 1032, so that the hinge unit 24 may be hinged to the

hinge portion 104. A locking portion 105 to couple with the locking unit 30 may be

provided at a right or second side of the flat portion 1032, so that the locking unit 30

may be coupled to the locking portion 105.

[0157] The door 12 may be fixed to the left and right or lateral sides of the flat

portion 1032 by the hinge unit 24 and the locking unit 30 when the laundry inlet port 106

is closed. The hinge portion 104 and the locking portion 105 may be disposed on the

87285939.3 horizontal center line CL-CL horizontally passing through the center of the flat portion

1032 in the radial direction, when looking at the circular flat portion 1032 from the front

of the main body 10.

[0158] A curling portion may be formed on an inner end of the flat portion 1032.

The curling portion may have a form in which an end of the flat portion 1032 is curled

into a rounded shape, thereby removing a sharp portion of the inner end of the flat

portion 1032. Accordingly, damage to laundry due to friction with the inner end of the flat

portion 1032 may be prevented when the laundry is loaded or unloaded through the

laundry inlet port 106 located at the inner end of the flat portion 1032, and injury to a

hand, for example, which may be caused due to a contact with the inner end of the flat

portion 1032 may be avoided.

[0159] Referring to FIGS. 4 and 5, the door window 23 may include an outer

edge portion or edge 231 formed in a circular shape on a front end thereof, and a

protruding portion 232 that protrudes toward the inside of the drum from the outer edge

portion 231. The protruding portion 232 may be in a curved shape. The protruding

portion 232 may have an upper surface, side surfaces, a lower surface, and a rear

surface. Both the side surfaces and the rear surface of the protruding portion 232 may

connect the upper and lower surfaces of the protruding portion 232.

[0160] The upper and lower surfaces of the protruding portion 232 may be

formed asymmetrically. For example, the upper surface of the protruding portion 232

may be inclined smoothly relative to the lower surface of the protruding portion 232, and

the lower surface of the protruding portion 232 may be inclined sharply relative to the

upper surface of the protruding portion 232.

87285939.3

[0161] The rear surface of the protruding portion 232 may be formed almost in a

perpendicularly flat surface. With this configuration, the door window 23 may be

disposed to cover the opening of the inner frame 19, and the protruding portion 232 may

protrude into the drum through the laundry inlet port 106 when the door 12 is closed.

[0162] When a large quantity of laundry is loaded into the drum, the laundry may

collide with the door window 23 protruding into the drum while rotating along an inner

circumferential surface of the drum. Embodiments disclosed herein are configured to

prevent the door 12 from being lifted towards the outside of the main body 10 due to the

collision between the laundry and the door window 23.

That is, contact portion (pivot portion) 191 may be provided on the rear

surface of the door frame 13. The contact portion 191 may be brought into contact with

the main body 10 when the door 12 is closed. The contact portion 191 may be formed

integrally with the rear surface of the inner frame 19. The contact portion (pivot portion)

191 may function as a pivot about which the door may pivot upon application of an

internalforce to the door.

[0163] The contact portion 191 may be in contact with a front end of a front panel

101, a front end of the recess 103, or a boundary portion between the front panel 101

and the recess 103. The boundary portion between the front panel 101 and the recess

103 may be a portion where the recess 103 starts to be recessed.

[0164] The recessed portion 1031 may be understood as a portion where the

recess 103 starts to be recessed. The contact portion 191 may be brought into contact

with the recessed portion 1031 of the recess 103. When the contact portion 191 is in

87285939.3 contact with the recessed portion 1031 of the recess 103, a contact area between the contact portion 191 and the main body 10 may be minimized.

[0165] When the contact portion 191 is in contact with the recessed portion 1031

of the recess 103, the contact portion 191 may be smoothly connected in a curved

shape to the rear surface of the inner frame 19 without protruding.

[0166] The rear surface of the inner frame 19 may have an arcuate cross section

and may be convex toward the front surface of the front panel 101 and the flat portion

1032. The rear surface of the inner frame 19 may have an arcuate cross section.

[0167] The rear surface of the inner frame 19 may be asymmetric at upper and

lower portions. The inner frame 19 may be formed such that an upper portion of the rear

surface has a greater curvature than the lower portion of the rear surface. The rear

surface of the inner frame 19 may be disposed to face the front panel 101 or the flat

portion 1032. The upper portion of the rear surface of the inner frame 19 denotes a

portion of the rear surface located above the horizontal center line CL-CL horizontally

passing through the center of the inner frame 19 in the radial direction, when looking at

the rear surface of the inner frame 19 from the rear side. The lower portion of the rear

surface of the inner frame 19 denotes a portion of the rear surface located below the

horizontal center line CL-CL.

[0168] The contact portion 191 may be located on the upper portion of the rear

surface of the inner frame 19, so as to allow the upper portion of the rear surface of the

inner frame 19 to be in contact with the recessed portion 1031 of the main body 10. The

contact portion 191 may be curved on the upper portion of the rear surface of the inner

87285939.3 frame 19. The contact portion 191 may have a curved shape having a greater curvature than that of the lower portion of the rear surface of the inner frame 19.

[0169] The contact portion 191 may have an arcuate shape from the rear surface

of the inner frame 19 toward the recessed portion 1031. The contact portion 191 may

circumferentially extend from the upper portion of the rear surface of the inner frame 19

so as to have an arcuate cross section. In this case, the contact portion 191 may have a

circumferential length which is 1/2 of or shorter than an entire circumference of the inner

frame along the circumferential direction of the inner frame 19. For example, when an

outer diameter of the inner frame 19 is D (mm), the contact portion 191 may be -rrD / 2

or shorter.

[0170] The contact portion 191 may be formed on one or a first side of the rear

surface of the inner frame 19 or a plurality of the contact portion 191 may be formed to

be spaced apart from the upper portion of the rear surface of the inner frame 19 in the

circumferential direction. In this embodiment, the single contact portion 191 having the

arcuate cross section extends from the upper portion of the rear surface of the inner

frame 19 along the circumferential direction is shown.

[0171] Referring to FIG. 7, the recessed portion 1031 may be inclined downward

toward the flat portion 1032 with respect to the perpendicularly-formed front surface of

the front panel 101. An outer side of a front end of the recessed portion 1031 connected

to the front surface of the front panel 101 may be rounded. The outer side of the front

end of the recessed portion 1031 may be formed to have a radius of curvature which is

significantly smaller than a radius of curvature of the contact portion 191.

87285939.3

[0172] A radius of an arc formed by the contact portion 191 may be much larger

than a radius of an arc formed by the outer side of the front end of the recessed portion

1031. The arc of the contact portion 191 and the arc formed by the outer side of the

front end of the recessed portion 1031 may be disposed to be adjacent to each other.

[0173] The contact portion 191 may be in contact with the outer side of the front

end of the recessed portion 1031 when the door 12 is closed, and contact between the

contact portion 191 and the outer side of the front end of the recessed portion 1031 may

be made on curved surfaces of the arcs externally brought into contact with each other.

The contact portion 191 formed on the rear surface of the door frame 13 may be in

contact with one or a first side of the main body 10, namely, the outer side (rounded

portion) of the front end of the recessed portion 1031 formed at the front panel 101,

when the door 12 is closed. The contact portion 191 may be in point contact or line

contact with the one side of the main body 10.

[0174] A first portion of the door frame 13 may protrude forward from the outer

side of the recess 103 based on the contact portion 191, and a second portion of the

door frame 13 may be accommodated in the recess 103.

[0175] Non-contact portion 192 may be provided on the lower portion of the rear

surface of the inner frame 19. The non-contact portion 192 may be formed with a

curvature smaller than that of the contact portion 191. The non-contact portion 192 may

be inclined smoothly relative to the contact portion 191. The non-contact portion 192

may be spaced forward apart from the lower side of the recessed portion 1031 of the

recess 103.

87285939.3

[0176] Therefore, according to embodiments disclosed herein, the contact portion

191 may be provided at the upper portion on the rear surface of the door frame 13, and

may be brought into contact with the recessed portion 1031 of the recess 103 of the

main body 10 when the door 12 is closed, so that lifting of the door 12 may be

prevented even if laundry spinning along the inner circumferential surface of the drum

collides with the door window 23 when the laundry is loaded in a large quantity.

[0177] More specifically, when a large quantity of laundry is accommodated in the

drum, the laundry may be moved down to the bottom of the drum by gravity and

centrifugal force in a state of being wet with water, and hit the lower portion of the door

window 23 during spinning. When an impact is applied to the door window 23 due to the

spinning of the laundry, the lower portion of the rear surface of the door frame 13 may

be pressed from the inside to outside of the drum.

[0178] In the state in which the hinge unit 24 and the locking unit 30 respectively

disposed at the lateral sides on the rear surface of the door frame 13 are fixed to the flat

portion 1032, the contact portion 191 provided at the upper portion on the rear surface

of the door frame 13 may be brought into contact with the recessed portion 1031 formed

in the front panel 101 of the main body 10, so as to resist lifting of the door 12, thereby

preventing vibration or shaking of the door 12 even if an impact is applied to the lower

portion of the door frame 13. In addition, the contact portion 191 extends in an arcuate

curved shape along the circumferential direction of the door frame 13. The contact

portion 191 may not protrude from one side of the rear surface of the door frame 13, but

rather, may form a curved surface smoothly connected to its adjacent portions without a

bent portion, thereby allowing the door to have a beautiful appearance.

87285939.3

[0179] In particular, the rear surface of the door 12 may be brought into contact

with the recessed portion 1031 where the recess 103 starts to be recessed, by the

contact portion 191. The contact portion 191 may cover the inside of the recess 103.

Therefore, the door window 23 protruding from the rear surface of the door to the inner

space of the main body 10 may be covered, thereby improving an appearance of the

door 12. In addition, the contact portion 191 of the door 12 may not protrude from the

rear surface of the door 12, but rather, may be brought into contact with the recessed

portion 1031 where the recess 103 starts to be recessed, without being in contact with

the flat portion 1032 of the recess 103, thereby preventing an increase in unnecessary

material cost due to an increase in size of the contact portion 191.

[0180] Also, the contact portion 191 may be curved toward the front panel 101 or

the recess 103 to have a cross section in an arcuate shape, so as to be in point contact

or line contact with the recessed portion 1031, thereby minimizing a contact area of the

contact portion 191 when the door 12 is closed. Accordingly, an impact applied to the

main body 10 may be dispersed along the circumferential direction of the recess 103

when the main body 10 is brought into contact with the contact portion 191 due to

rotation of the door 123, resulting in minimizing the impact applied to the main body 10.

[0181] A contact state between the contact portion 191 and the main body 10

may be maintained after the door 12 is closed, and thus, vibration and noise occurring

between the door 12 and the main body 10 may be minimized even though an impact is

repetitively applied from the laundry accommodated in the drum through the door

window 23. In addition, even if the lower portion of the door frame 13 is lifted inside of

the drum due to the impact applied to the door window 23, lateral sides of the door 12

87285939.3 and the upper end of the door 12 may be supported at a plurality of points on the front panel 101. For example, the plurality of points may include at least three support points, such as each vertex of a triangle. Both left and right or lateral support points of the three support points may be formed as the hinge unit 24 and the locking unit 30 of the door 12 are coupled to the main body 10. The upper support point of the three support points may be formed by the contact between the contact portion 191 and the main body 10.

According to this, a suppression force against vibration or shaking of the door 12 may

be improved significantly.

[0182] In addition, as the arcuate curved surface of the contact portion 191 and

the arcuate curved surface of the recessed portion 1031 where the door 12 and the

main body 10 are in contact with each other may realize a point contact or a line contact

with each other, thereby minimizing friction between mutual contact surfaces. Moreover,

even if lifting of the door 12 occurs, the contact point between the door frame 13 and the

recess 103 moves on the arcuate curved surface, so as to prevent the contact portion

191 of the door frame 13 from being spaced apart from the main body 10, thereby

achieving stable contact.

[0183] In addition, an impact transferred from the inside of the drum through the

door window 23 may be alleviated by virtue of stable contact between the contact

portion 191 of the door frame 13 and the recess 103 of the main body 10. Accordingly,

neither a separate buffer member between the door 12 and the main body 10 nor an

installation space of the buffer member are needed, thereby accommodating more of

the door 12 in the recess 103, resulting in implementing a compact arrangement of the

door 12.

87285939.3

[0184] FIG. 9 is a schematic view illustrating a state in which a contact portion

291 protrudes from one side of the rear surface of the door frame 13 in accordance with

another embodiment. FIG. 10 is a schematic view illustrating a shape of the contact

portion 291 of FIG. 9, viewed from the rear of the door frame 13.

[0185] This embodiment is different from the previous embodiment of FIGS. 4 to

8 in that the contact portion 291 integrally protrudes from one side of the rear surface of

the door frame 13. The contact portion 191 illustrated in FIGS. 4 to 8 protrudes in the

curved shape from the upper portion (predetermined section) of the rear surface of the

door frame 13 continuously along the circumferential direction so as to have the arcuate

cross section (except for the handle), whereas the contact portion 291 according to this

embodiment locally protrudes from the upper portion of the rear surface of the door

frame 13.

[0186] In this embodiment, the contact portion 291 may protrude in various forms,

such as an oval, circle, or rectangle, for example. In addition, a plurality of the contact

portion 291 may be provided, and the plurality of contact portions 291 may be spaced

apart from each other in the circumferential direction.

[0187] The other components are the same/like those of the previous

embodiment. Thus, detailed description thereof has been omitted.

[0188] Embodiments disclosed herein may solve problems of the related art.

Embodiments disclosed herein provide a laundry treating apparatus capable of

preventing periodic vibration and noise caused between a door and a main body due to

collision between laundry, which spins together with a drum, and a door window, when

the laundry is loaded in a large quantity inside of the drum. Embodiments disclosed

87285939.3 herein provide a laundry treating apparatus having a door with a beautiful appearance, because there is no need to form a protruding structure on a rear surface of the door for mitigating an impact applied to the door.

[0189] Embodiments disclosed herein provide a laundry treating apparatus

capable of alleviating an impact transferred to a main body from a door even without a

separate buffer member, simplifying a structure, and reducing cost. Embodiments

disclosed herein also provide a laundry treating apparatus capable of minimizing wear

caused due to friction between a door and a main body. Embodiments disclosed herein

provide a laundry treating apparatus capable of alleviating an impact applied to a main

body due to contact between a door and the main body even in a closed state of the

door.

[0190] According to embodiments disclosed herein, a contact portion which

comes in contact with a main body may be provided at an upper portion on a rear

surface of a door frame. Even though an impact is transferred to a lower side of a door

through a door window, an upper side of the door may be maintained in a contact state

with the main body by virtue of the contact portion when the door is closed, which may

result in preventing vibration and noise caused between the door and the main body.

[0191] According to embodiments disclosed herein, the contact portion may be

formed in a curved shape with a preset or predetermined curvature at the upper portion

on the rear surface of the door frame along a circumferential direction so as to come in

contact with the main body. When viewed with the naked eye, the door frame does not

have a structure in which one side portion protrudes compared to another side portion,

thereby realizing a door with a beautiful appearance.

87285939.3

[0192] According to embodiments disclosed herein, the contact portion may be

formed integrally at the upper portion on the rear surface of the door frame so as to

come in contact with the upper portion of the main body, thereby alleviating an impact

by the contact portion even without a separate buffer member, simplifying a structure,

and reducing material cost. The contact portion may be formed in a shape curved with a

preset or predetermined curvature, and a recessed portion where a recess part or

recess in contact with the contact portion starts to be recessed may be formed in a

shape curved in an opposite direction to the contact portion. Accordingly, the contact

portion may be externally brought into point contact or line contact with the recess part

of the main body, so as to minimize a contact area between the door and the main

body, thereby minimizing an occurrence of wear due to friction between the door and

the main body.

[0193] The contact portion may have a cross section in an arcuate shape, and a

recessed portion where a recess part accommodating part of the door starts to be

recessed may be formed in a rounded shape, which may result in mitigating an impact

transferred to the door upon the contact between the contact portion and the recess part

even while the door is closed.

[0194] Embodiments disclosed herein provide a laundry treating apparatus that

may include a main body and a door. A front panel of the main body may define a front

surface of the main body. The front panel may be provided with a laundry inlet port. The

front panel may be provided with a recess part or recess recessed therein. The recess

part may surround the laundry inlet port.

87285939.3

[0195] The door may be rotatably mounted to the front panel to open and close

the laundry inlet port. The door may include an outer frame, a door window, an inner

frame, and a contact portion.

[0196] The outer frame may be provided with a front glass on a front surface

thereof. An outer circumferential portion of the outer frame may protrude to outside of

the recess part to surround an outer surface of the front glass. The door window may be

disposed to correspond to the laundry inlet port, and an outer edge portion or edge of

the door window may be accommodated inside of the recess part.

[0197] The inner frame may be disposed toward the recess part. An outer side of

the inner frame may be connected to the outer circumferential portion of the outer

frame. An inner side of the inner frame may be connected to the outer edge portion of

the door window.

[0198] The contact portion may be provided between the outer side and the inner

side of the inner frame. The contact portion may come in contact with the recessed

portion of the recess part, when the door is closed.

[0199] The contact portion may absorb an impact transferred from a large

quantity of laundry to the door when the large quantity of laundry is loaded, as an upper

side of the door with respect to a horizontal center line horizontally passing through a

center of the door in a radial direction may be in contact with the main body so as to be

supported by the main body, and a lower side of the door may absorb the impact by

being pushed forward by the impact transferred from the laundry. If the contact portion

is spaced apart from the main body without contacting it, the same problems as in the

related art may occur.

87285939.3

[0200] The inner frame may be formed in a ring shape and the contact portion

may be located at an upper portion of the inner frame based on a horizontal center line

horizontally passing through a center of the inner frame in a radial direction. Because a

protruding portion is formed at a lower portion of the door window with respect to the

horizontal center line, the contact portion may be located at the upper portion of the

inner frame, in view of structural characteristics of the door window.

[0201] The contact portion may be formed in a shape curved from the outer side

of the inner frame to the inner side of the inner frame in a direction toward the recess

part. The contact portion may have a cross section in an arcuate shape. The contact

portion may extend in a circumferential direction. The contact portion may extend along

the circumferential direction, without protruding from the rear surface of the inner frame

when a user views the rear surface of the inner frame, thereby obtaining a better

appearance.

[0202] The contact portion may have a greater curvature than a lower portion of

the inner frame. Accordingly, the contact portion may come in contact with a recessed

portion where the recess part starts to be recessed, and the lower portion of the inner

frame cannot come in contact with the recess part.

[0203] A top end of the outer side of the inner frame may be located higher than

a contact point of the contact portion. The outer side of the inner frame may have a

diameter greater than that of the recess part, and the inner side of the inner frame may

have a diameter smaller than that of the recess part. The outer side of the inner frame

may be spaced forward apart from a contact point of the contact portion. Thus, the door

may be larger than the recess part in size.

87285939.3

[0204] A handle may be provided on an upper portion of the outer side of the

inner frame. The handle may be recessed into the inner frame toward the front glass.

The handle may be spaced apart from a top end of the contact portion in a

circumferential direction of the inner frame.

[0205] The front glass may have front and rear surfaces in a shape of a circular

plate. The outer frame may include a mounting guide that protrudes from the outer

circumferential portion to surround an outer surface of the front glass.

[0206] The outer frame may include an adhesive groove and a flat portion. The

adhesive groove may be formed in the flat portion for receiving an adhesive for adhering

the front glass to the outer frame. The flat portion may be formed inside of the mounting

guide. The outer frame may further include a curved portion. The curved portion may

extend with a preset or predetermined curvature from inside of the flat portion toward

the outer edge portion of the door window. An opening may be formed inside of the

curved portion.

[0207] The outer frame may have a ring shape. The outer circumferential portion

of the outer frame may have a diameter larger than that of the recess part.

[0208] A portion where the recessed portion starts to be recessed may be curved

to be externally brought into contact with the contact portion. The contact portion may

come in point contact or line contact with the recess part.

[0209] Embodiments disclosed herein provide a laundry treating apparatus that

may include a main body provided with a front panel having a laundry inlet port, and a

recess part or recess recessed into the front panel to surround the laundry inlet port,

and a door rotatably mounted to the front panel to open and close the laundry inlet port.

87285939.3

The door may include an outer frame that protrudes outward from the recess part and

having an outer circumferential portion with a larger diameter than the recess part, and

an inner frame provided with a contact portion in contact with a recessed portion of the

recess part, and having an outer side protruding to outside of the recess part to be

coupled to the outer circumferential portion of the outer frame, and an inner side

accommodated inside of the recess part.

[0210] The contact portion may extend in a curved shape from the outer side to

the inner side of the inner frame, so as to come in contact with a portion where the

recess part starts to be recessed, when the door is closed. The outer frame and the

inner frame may be disposed to cover the recess part.

[0211] With embodiments disclosed herein, a contact portion may be provided at

an upper portion on a rear surface of a door frame, to come in contact with one side of

an upper portion of a front panel provided on a main body when a door is closed,

thereby preventing lifting of the door even if a door window collides with laundry, which

rotates along an inner circumferential surface of a drum, when the laundry is loaded in a

large amount. Left and right or lateral sides of the door frame may be fixed to a flat

portion by a hinge unit and a locking unit. The contact portion provided on the upper

portion of the rear surface of the door frame may come in contact with a recessed

portion where a recess part or recess formed in a front panel starts to be recessed, so

as to resist lifting of the door. Even if an impact is repeatedly applied from the rotating

laundry to a lower portion of the door frame through the door window, the contact

portion may be kept in contact with the main body, thereby remarkably reducing

vibration and noise between the door and the main body.

87285939.3

[0212] The contact portion may extend to be curved in an arcuate shape along a

circumferential direction of the door frame. Thus, the contact portion does not protrude

from one side of the rear surface of the door frame but forms a curved surface smoothly

connected to its adjacent portions without a bent portion, thereby allowing the door to

have a beautiful appearance.

[0213] In particular, a rear surface of the door is brought into contact with the

portion where the recess part starts to be recessed, by virtue of the contact portion.

Accordingly, the contact portion covers an inside of the recess part. Therefore, the door

window protruding from the rear surface of the door to the inner space of the main body

may be covered, thereby improving an appearance of the door. In addition, the contact

portion of the door comes in contact with the recessed portion where the recess part

starts to be recessed without protruding from the rear surface of the door and also

contacting a flat surface of the recess part, thereby preventing an increase in

unnecessary material cost due to an increase in size of the contact portion.

[0214] The contact portion has a cross section in an arcuate shape and is curved

toward the front panel or recess part, so as to come in point contact or line contact with

an outer circumference of the recess part. Accordingly, a contact area of the contact

portion may be minimized when the door is closed, thereby distributing an impact, which

is applied to the main body when the contact portion of the door comes in contact with

the recess part of the main body, along the circumferential direction of the recess part,

which may result in minimizing an impact applied to the main body.

[0215] Even if the lower portion of the door frame is lifted inside of the drum due

to an impact applied to the door window, the hinge unit and the locking unit coupled to

87285939.3 the main body and the contact portion comes in contact with an upper end of the recess part when the door is closed. Accordingly, at least three support points, like an equilateral triangle, a rectangle, and a polygon, may be formed by the contact between the door and the main body, thereby reducing vibration or shaking of the door and absorbing an impact applied to the door.

[0216] An arcuate curved surface of the contact portion and an arcuate curved

surface of an outer circumference of the recess portion may come in point contact or

line contact with each other between the door and the main body, thereby minimizing

friction between the door and the main body. Even if the door is lifted due to an impact

transferred from laundry, the contact portion and the recess part are externally brought

into contact with each other. Accordingly, a contact point between the contact portion

and the recess part may move on the arcuate curved surface of the contact portion,

thereby preventing separation between the contact portion of the door frame and the

recess part of the main body so as to realize stable contact between them.

[0217] By stable contact between the contact portion of the door frame and the

recess part of the main body, an impact transferred from inside of the drum through the

door window may be mitigated. In addition, a separate buffer member between the door

and the main body and an installation space of the buffer member may not be needed.

Accordingly, the door may be more accommodated in the recess, thereby implementing

a compact arrangement of the door.
