Description

Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of the earlier filing date and the right of priority to Korean Patent Applications No. 10-2019-0014095, filed in Korea on Feb. 1, 2019, and No. 10-2019-0060211, filed in Korea on May 22, 2019, the contents of which are incorporated by reference herein in their entirety.

BACKGROUND

1. Field

A laundry treating apparatus having a door that opens and closes a laundry inlet port of a main body are disclosed herein.

2. Background

Laundry treating apparatuses may include apparatuses for washing laundry or other items (hereinafter, collectively referred to as “laundry”), apparatuses for drying laundry, and apparatuses for washing and drying laundry. In the laundry treating apparatus, washing laundry is an operation for removing contaminants from the laundry using water and detergent, and drying laundry is an operation for removing moisture contained in the laundry using a hot air supply device provided in the laundry treating apparatus.

A door of a laundry dryer/drum washing machine is disclosed in Korean Registration Patent Application No. 10-0595180, registered on Jun. 23, 2006 and hereinafter, referred to as “Patent Document 1”, which is hereby incorporated by reference. The laundry treating apparatus disclosed in Patent Document 1 is equipped with a main body provided with a laundry inlet port on a front surface, and a door configured to open and close the laundry inlet port. The door may include a door frame rotatably coupled to the main body by a hinge unit, an outer window attached to a front surface of the door frame to define a front appearance of the door, and an inner window disposed to correspond to an opening in the door frame.

The door frame includes an outer door frame disposed toward an outside of the main body and an inner door frame disposed toward an inside of the main body, and the outer door frame and the inner door frame are fastened to each other. As each of the outer window and the inner window is made of a transparent material, a washing state inside of the drum may be viewed through the door window even when the door is closed. However, the related art laundry treating apparatus has the following problems.

First, moisture or water penetrates into a gap between the outer door frame and the inner door frame and remains inside of the door.

Second, the outer window is disposed to cover a front surface of the door frame, and when water or moisture (liquid) that has penetrated into the door through the gap between the outer door frame and the inner door frame is introduced into the outer window side, the outer window may appear cloudy. As the door window occupies a substantial portion of the front surface of the laundry treating apparatus, the above-described problem may act as a factor that degrades a sense of quality of the laundry treating apparatus.

A laundry treating apparatus is disclosed in Korean Registration Patent Application No. 10-1708352, registered on Feb. 14, 2017 and hereinafter, referred to as “Patent Document 2”, which is hereby incorporated by reference. Referring to the abstract and FIG. 3 of Patent Document 2, the door includes a door frame, a door cover, and a door window.

The door cover is attached to a front surface of the door frame, defining an appearance of the door. The door frame may include an outer frame disposed toward an outside of the main body, and an inner frame fastened to a rear surface of the outer frame. The door window is mounted between the outer frame and the inner frame so as to correspond to the laundry inlet port.

However, with the door of Patent Document 2, moisture or water may penetrate inside of the door through a gap between the inner frame and the door window. In this case, moisture or water which has penetrated inside of the door causes water droplets to form on the door cover, such as steam. For this reason, it is difficult to see the washing state inside of the main body through the door cover and the door window.

FIG. 1 is a perspective view of a laundry treating apparatus according to an embodiment. The laundry treating apparatus disclosed herein may include a main body 10, a laundry accommodating portion, and a door 12. The main body 10 may define an outer shape or appearance of the laundry treating apparatus. The main body 10 may be defined in a rectangular parallelepiped shape.

The main body 10 may include a front panel 101, a rear panel, side panels, an upper panel, and a lower panel. The front panel 101 may define a front surface of the laundry treating apparatus. The rear panel may define a rear surface of the laundry treating apparatus. The side panels may define left and right or lateral sides of the laundry treating apparatus, respectively. The upper panel may define an upper surface of the laundry treating apparatus. The lower panel may define a lower surface of the laundry treating apparatus.

A laundry inlet port 106 (see FIG. 12) may be defined in a circular shape through the front panel 101 so as to allow laundry to be put into the laundry accommodating portion through the laundry inlet port 106. A recess 103 (see FIG. 12) may be formed in the front panel 101. The recess 103 may be recessed in a circular shape. The recess 103 may surround the laundry inlet port 106. The recess 103 may accommodate a portion of a rear surface of the door 12. The laundry inlet port 106 may be formed eccentrically from a center of the recess 103.

A center of the laundry inlet port 106 may be formed inside of the recess 103 to extend directly upward from a center of the recess 103. An upper portion on the rear surface of the door 12 may be brought into contact with a circumference of the recess 103, and a lower portion on the rear surface of the door 12 may be spaced apart from the circumference of the recess 103 (see FIG. 12).

A contact portion 191 in contact with the circumference of the recess 103 may be provided on the upper portion on the rear surface of the door 12. A non-contact portion 192 spaced apart from the circumference of the recess 103 may be provided on the lower portion on the rear surface of the door 12. The contact portion 191 may protrude on the upper portion on the rear surface of the door 12 having a cross section in an arcuate shape.

The non-contact portion 192 may be inclined on the lower portion on the rear surface of the door 12. The circumference of the recess 103 may be rounded. Upper portions of the circumferences of the contact portion 191 and the recess 103 may be disposed to contact each other. According to this embodiment, the contact portion 191 may minimize vibration or shaking of the door 12 due to a collision between laundry and the door window 23 (see FIG. 12).

The laundry accommodating portion may be provided inside of the main body 10. The laundry accommodating portion may include (accommodate) a drum to perform a drying function, or a tub and a drum to perform washing and drying functions together.

In embodiments disclosed herein, in order to perform washing and drying functions together, a tub and a drum may be provided inside of the main body 10. The tub may be defined in a cylindrical shape. The tub may be disposed such that a central axis of the tub is horizontal or inclined at a predetermined angle in a lengthwise direction of the tub. The tub may be configured to store wash water inside thereof.

A gasket may be provided at a front end portion or end of the tub to communicate with the laundry inlet port 106. The gasket may prevent wash water stored inside of the tub from leaking into an accommodation space of the main body 10.

The drum may be provided in the tub to be rotatable with respect to the tub. A plurality of through holes may be formed through a circumferential surface of the drum. The plurality of through holes may allow a fluid, such as wash water, to be introduced into the drum or discharged from the drum to the tub.

A front portion of the drum may be open. The front portion of the drum may be in communication with the laundry inlet port 106. Laundry may be accommodated inside of the drum through the laundry inlet port 106.

A drive motor may be installed on a rear surface of the tub. The drive motor may be connected to the rear surface of the drum through a rotational shaft. As the drive motor is driven, power of the drive motor is transmitted to the drum through the rotational shaft, thereby rotating the drum.

The drum may be provided with a plurality of lifters therein. The drum may be configured to rotate laundry accommodated inside of the drum to a top of the drum by the plurality of lifters to perform washing and drying functions.

For example, the plurality of lifters may rotate along with the drum. The laundry spins from a bottom to a top of the drum along an inner circumferential surface of the drum. The laundry may fall to a bottom of the drum due to gravity. According to this, an effect of washing dirty laundry by beating the laundry with a paddle may be simulated.

A controller (control panel) 11 may be configured to display information related to operations of the laundry treating apparatus to a user and to receive the user's input. The controller 11 may include a display that displays visual information.

The controller 11 may include, for example, a circular knob and a plurality of buttons to receive the user's input. The controller 11 may be provided on the main body 10 or provided on the door 12. In embodiments disclosed herein, the controller 11 is located on an upper portion of the front panel 101 of the main body 10.

The door 12 may be rotatably installed on the front panel 101. The door 12 may be configured to open and close the laundry inlet port 106.

FIG. 2 is a front view of door 12 in FIG. 1. FIG. 3 is an exploded view of door 12 in FIG. 2. FIG. 4 is a planar view of door 12 in FIG. 2. FIG. 5 is a left side view of door 12 in FIG. 2. FIG. 6 is a rear view illustrating a rear surface of door 12 in FIG. 2. FIG. 7 is a view illustrating an upper side, a lower side, a left side, and a right side of front glass 20 in FIG. 3, respectively.

The door 12 may include a door frame 13, door window 23, front glass 20, a hinge unit or hinge 24, and a locking unit 30. The door frame 13 may be defined in a ring shape. An opening 18 may be located at an inner side of the door frame 13.

The door frame 13 may include an outer frame 14 and an inner frame 19. The outer frame 14 and the inner frame 19 may be formed of a synthetic resin material, for example, an acrylonitrile butadiene styrene (ABS) material, or a polycarbonate (PC) material. Each of the outer frame 14 and the inner frame 19 may be manufactured by injection molding, for example.

The outer frame 14 and the inner frame 19 may each have a ring shape. The inner frame 19 may be coupled at a rear surface side of the outer frame 14. A coupling between the outer frame 14 and the inner frame 19 may be made by pin-groove coupling, hook coupling, screw coupling, or bonding coupling, for example. In embodiments disclosed herein, each of the outer frame 14 and the inner frame 19 may be provided with a hook 36 at an outer circumference thereof to be engaged with each other by, for example, an interference or snap fit.

The outer frame 14 is disposed toward or faces an outside of the main body 10 and the inner frame 19 is disposed toward or faces an inside of the main body 10 in a state in which the door 12 is closed. The outer frame 14 may be referred to as a “first frame”, and the inner frame 19 may be referred to as a “second frame”.

The opening 18 may be circular and provided at inner side of the outer frame 14 and the inner frame 19, respectively, to face the laundry inlet port 106. The opening 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 the centers of each of the outer frame 14 and the inner frame 19.

According to embodiments disclosed herein, each of the outer frame 14 and the inner frame 19 may vary in width along a circumferential direction. The term “width” may refer to a distance between an outer diameter and an inner diameter of the outer frame 14 or the inner frame 19. For example, a width of each of the outer frame 14 and the inner frame 19 may increase (widen) from a top end to a bottom end.

A center of the drum may be disposed higher than a center of a height (½) 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.

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 prefer to look into the drum through the door 12, and if possible, have a wide field of view with regard to an inner space of the drum.

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 the center of the laundry inlet port 106 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, in order to increase the size of the door 12, a portion of the door 12 that protrudes outward from the recess 103 and the door 12 may be provided with a larger diameter.

The front glass 20 may be attached to a front surface of the outer frame 14. The front glass 20 may cover the opening 18 of the door frame 13. The front glass 20 may be bonded to the front surface of the outer frame 14 by a sealant or an adhesive 38 (see FIG. 8), for example.

Due to a nature of the glass material, the front glass 20 is easily broken when a coupling hole is drilled into the front glass 20, and thus, the front glass 20 is attached to the outer frame 14 using an adhesive, for example, to prevent the glass from being broken. 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 the front surface of the outer frame 14.

In particular, the front glass 20 may be made of tempered glass. Due to a nature of tempered glass, front and rear surfaces of the front glass 20 have a high strength; however, a circular outer circumferential surface, which is a side surface of the front glass 20, has a low strength.

To compensate for this, the mounting guide 34 may protrude forward from a front outer circumferential end of the outer frame 14 to surround an outer circumferential surface of the front glass 20. The mounting guide 34 may have a predetermined inner diameter and a ring shape. The mounting guide 34 may define a space in which the front glass 20 may be accommodated therein.

An inner diameter of the mounting guide 34 may correspond to an outer diameter of the front glass 20. The mounting guide 34 may surround the outer circumferential surface of the front glass 20.

The mounting guide 34 may support the load of the front glass 20 as well as protect the side surface of the front glass 20 from external impact. A protruding length of the mounting guide 34 may cover at least ⅔ 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 may break the front glass 20 when the protruding length of the mounting guide 34 is too short.

For example, a straight portion 202 (see FIG. 14) and a plurality of curved portions 201, 203 may be arranged on a side or circumferential surface, which is cut in a diameter (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 a front surface of the front glass 20 and second curved portion 203 connected to a 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 ⅓ of the thickness of the front glass 20. The mounting guide 34 may cover the second curved portion 203 and the straight portion 202 of the front glass 20.

The front glass 20 may include a transparent region 21 and a non-transparent region 22. The transparent region 21 may be disposed at an inside of the front glass 20. The non-transparent region 22 may be disposed at an outside of the front glass 20.

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 is a translucent region.

In a state in which the front glass 20 is attached to the door frame 13, the transparent region 21 may be disposed to correspond to the opening 18 of the door frame 13 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.

A center of the transparent region 21 may be located at a position corresponding to the 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 with the center, but also alignment in an eccentric direction of the center.

That is, in embodiments disclosed herein, the center of the opening 18 may be eccentrically located from the center of the door frame 13 to an upper side (12 o'clock direction). Correspondingly, the center of the transparent region 21 may also be 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.

The non-transparent region 22 may surround the transparent region 21. The non-transparent region 22 does not transmit light. The non-transparent region 22 may cover a 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. Alternatively, the boundary between the transparent region 21 and the non-transparent region 22 may be blurred by a halftone technique, thereby providing 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. The plurality of shielding dots may be arranged to have a lower density toward the transparent region 21.

Referring to FIG. 7, the front glass 20 may have a circular shape with a predetermined radius. The front glass 20 may be made of a glass material. The front glass 20 may be flat on front and rear surfaces thereof.

The front glass 20 may have a disc shape with a constant thickness, without bending even when viewed from any direction, that is, up, down, left, or right.

According to embodiments disclosed herein, the front glass 20 in a shape of a circular plate may enhance a quality grade of the door 12, compared to a door cover in the related art made of a synthetic resin material having a convex front surface in an incomplete circular shape.

The front glass 20 may include the transparent region 21, the non-transparent region 22, and an alignment mark (not illustrated) in a layered structure. The alignment mark may be a portion displayed on one side of the non-transparent region 22 to align the front glass 20 to the front surface of the outer frame 14. For example, the front glass 20 may include a glass body and a shielding layer. The glass body may be formed of a glass material having transparency. The shielding layer may cover a rear surface of the glass body. The shielding layer may form the non-transparent region 22.

In this case, a portion where the shielding layer is not disposed may define the transparent region 21 and an alignment mark. The shielding layer may be formed on the rear surface of the glass body in a glass printing manner, for example.

As another example, the front glass 20 may include a glass body and a film. The glass body may be formed of a glass material having transparency. The film may cover the rear surface of the glass body. The film may include a transparent portion having transparency corresponding to the transparent region 21, a non-transparent portion having non-transparency corresponding to the non-transparent region 22, and an alignment portion having transparency corresponding to the alignment mark.

As another example, the front glass 20 may include a glass body and a film. The glass body may be formed of a glass material having transparency. The film may cover the rear surface of the glass body. A difference from the above example is that the film may include a first hole corresponding to the transparent region 21, a non-transparent portion having non-transparency corresponding to the non-transparent region 22, and a second hole corresponding to the alignment mark. That is, there is a difference in whether the film has portions corresponding to the transparent region 21 and the alignment mark or through holes.

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 with the non-transparent region 22. Adhesive 38 (see FIG. 8) may be applied to the flat portion 15 so that the front glass 20 may be adhered to the flat portion 15.

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

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.

The protection layer 17 may coat the outer frame 14 with a silver polished metal color. According to this, the protection layer 17 may obtain an effect in that it looks like circular droplets of bright silver. In addition, the protection layer 17 may produce a sense of high quality, for example, when viewed with the naked eye.

The door window 23 may correspond to the laundry input port 106 when 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.

The door window 23 may be made of a transparent material, for example, a synthetic resin material having transparency. An inner space of 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. 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.

Referring to FIGS. 3 to 6, the door 12 may be rotatably provided in a frontward-rearward direction with respect to the main body 10 by the hinge unit 24. The hinge unit 24 may be mounted at one or a first side of the door 12. When the user looks at the closed door 12 from the front of the main body 10, the hinge unit 24 may be coupled to a left side.

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 may be rotatably coupled to the door frame 13. The hinge 25 may have a base portion 26 and a rotational coupling portion 27. The base portion 26 may have a plate shape coupled to the main body 10.

The rotational coupling portion 27 may protrude from the base portion 26 to be rotatably coupled to the door frame 13. A plurality of rotational coupling portions 27 may be provided spaced apart from each other in a vertical direction.

The hinge holder 28 may be coupled to the door frame 13 to support the rotational coupling portion 27. The hinge holder 28 may prevent the rotational coupling portion 27 from being released from the door frame 13.

The bush 29 may have a cylindrical shape to surround a rotational shaft of the rotational coupling portion 27. The bush 29 may be inserted into a rotational shaft of each rotational coupling portion 27 to smoothly rotate the rotational shaft.

The locking unit 30 may be provided at another or a second side of the door 12. When the user looks at the door 12 from the front of the main body, the locking unit 30 may be, for example, coupled to a right side on the rear surface of the door 12. The locking unit 30 may be configured to lock or unlock the door 12 to or from the main body 10.

The locking unit 30 may include a shaft 31, a door latch 32, and a spring 33. The shaft 31 may be inserted through the door latch 32 to be mounted to the door frame 13. The spring 33 has an elastic force to restore the door latch 32 when the door latch 32 is rotated.

According to embodiments disclosed herein, the door latch 32 may be rotatable and restorable with respect to the door frame 13. The door latch 32 may lock or unlock the door 12 with respect to the main body 10.

Referring to FIG. 4, handle 35 may be configured in a manner of recessing a rear upper side of the inner frame 19. The user may open the door 12 by pulling the handle 35.

The rear surface of the inner frame 19 may be convex rearward in an arcuate shape. 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 on a front side of the door. However, in embodiments disclosed herein, as the front glass 20 covers the 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, is provided on a rear surface of the door 12. The handle 35 may be provided on the inner frame 19.

In addition, the handle 35 may be installed at a top portion of the door 12 so that the user may 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.

As the hinge unit 24 and the locking unit 30 are respectively provided at left and right or lateral sides of the door frame 13, respectively, along a horizontal center line CL-CL that horizontally passes through a 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. 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.

FIG. 8 is a front view of a front surface of the outer frame 14 in FIG. 3. Referring to FIG. 8, the adhesive 38 may be disposed between the door frame 13 and the front glass 20. An adhesive groove 37 to which the adhesive 38 may be applied may be formed in the door frame 13. In FIG. 8, a state in which the adhesive groove 37 is formed on the front surface of the outer frame 14 is illustrated.

The adhesive groove 37 may be defined in a ring shape having a predetermined radius along the circumference of the mounting guide 34. The adhesive groove 37 may surround the opening 18. A gap between the mounting guide 34 and the adhesive groove 37 may be constant along the circumference of the mounting guide 34. That is, a center of the adhesive groove 37 may correspond to a center of the mounting guide 34.

As illustrated, the adhesive groove 37 may include an adhesive groove 371 and adhesive overflow groove 372. The adhesive groove 371 is a groove for receiving the adhesive 38 and may have a ring shape surrounding the opening 18.
