Description
- This application claims the benefit of Korean Application(s) No. 10-2002-0075024 filed on Nov. 28, 2002, which is/are hereby incorporated by reference.
- 1. Field of the Invention
- The present invention relates to a filter assembly of a washing machine for removing particles from water, and more particularly, to a filter assembly of a washing machine which opens/closes a filter hole provided in a cabinet to replace a filter.
- 2. Discussion of the Related Art
- Generally, a washing machine is an apparatus for eliminating dirt or filth attached to a laundry using reaction between water and detergent.
- Such a washing machine is classified into a pulsator type, an agitator type, and a drum type. The agitator type washing machine rotates an agitator protruding from a bottom center of a tub in forward and reverse directions to perform washing. The pulsator type washing machine rotates a disc-type pulsator on a bottom of a tub in forward and reverse directions to perform washing using a frictional force between a generated current and a laundry. And, the rum type washing machine rotates a drum holding water, detergent, and laundry at low speed to perform washing. In this case, a plurality of tumbling ribs protrude from an inside of the tub.
- If washing is performed using one of the various type washing machines, particles such as lint and the like are separated from the laundry. Lots of particles are accordingly contained in the used water after completion of the washing.
- Meanwhile, the used water is generally discharged outside using a drain pump. In such a case, such particles as lint and the like are frequently stuck in an impeller of the drain pump or a motor shaft, whereby drain capacity of the washing machine is lowered, noise is generated, and the drain pump may be out of order.
- Lately, many efforts are made to development of a washing machine equipped with a filter assembly enabling to remove particles involved in water.
- Moreover, since particles are naturally gathered in a filter of an operating washing machine, the filter should be cleaned or replaced. Hence, a hole for taking out the filter and a cover for opening/closing the hole should be provided to a cabinet of the washing machine.
- However, the cover should block the opening tightly as well as be detachable with ease. Besides, the cover provided at an outside of the cabinet should not spoil the exterior beauty of the washing machine.
- Accordingly, the present invention is directed to a filter assembly of a washing machine that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
- An object of the present invention, which has been devised to solve the foregoing problem, lies in providing a filter assembly of a washing machine, by which a hole provided on an outside of a cabinet is securely covered.
- It is another object of the present invention to provide a filter assembly of a washing machine, which provides an improved structure to be open with ease.
- It is another object of the present invention to provide a filter assembly of a washing machine, by which the exterior beauty of a cabinet is preserved.
- Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent to those having ordinary skill in the art upon examination of the following or may be learned from a practice of the invention. The objectives and other advantages of the invention will be realized and attained by the subject matter particularly pointed out in the specification and claims hereof as well as in the appended drawings.
- To achieve these objects and other advantages in accordance with the present invention, as embodied and broadly described herein, there is provided a filter cover assembly of a washing machine including a cover fitted to a filter hole provided at a cabinet of the washing machine for loading/unloading a filter, three protrusions extending downward from lo left, right, and central sides of a lower end of the cover to be inserted in holes at left, right, and central portions of a lower side of a filter case provided in the cabinet, respectively to communicate with the filter hole, and three hooks protruding from left, right, and central sides of an upper end of the cover toward the filter case to be inserted in hook holes at left, right, and central portions of an upper side of the filter case, respectively.
- In this case, at least one of the protrusions may include at least one slit provided along a length direction of the corresponding protrusion to elastically deform both lateral sides of the corresponding protrusion inward and outward and a barb protruding outward from lower ends of both of the lateral sides of the corresponding protrusion to prevent the corresponding protrusion having inserted in the hole from being separated from the hole.
- And, each of the hooks may include an extension part protruding from an upper end of the cover toward the filter case, an elastic part bent from an end of the extension part toward the cover to have elasticity upward and downward, and a barb protruding from an upper surface of the elastic part to be inserted in the corresponding hook hole. In this case, each of the hooks may further include a push piece extending from the elastic part to facilitate a user to push.
- It is to be understood that both the foregoing explanation and the following detailed description of the present invention are exemplary and illustrative and are intended to provide further explanation of the invention as claimed.

- FIGS.1 to 3 illustrate a washing machine according to a first embodiment of the present invention. A structure of a washing machine according to a first embodiment of the present invention is explained by referring to FIGS. 1 to 3 as follows.
- Referring to FIG. 1, a tub (not shown in the drawing) is provided in a
cabinet 10, and adrum 20 is rotatably provided in the tub. And, a spring (not shown in the drawing) and a damper (not shown in the drawing) are provided between thecabinet 10 and the tub to support the tub elastically. The provided spring and damper play a role in suspending the tub in thecabinet 10 as well as attenuating vibrations applied to the tub while a washing machine operates. Moreover, a motor is provided in rear of the tub so that thedrum 20 is connected to the motor to rotates. - A multitude of perforated
holes 21 perforate an outer circumference of thedrum 20, and a plurality oftumbling ribs 25 are provided on an inner circumference of thedrum 20. Hence, water supplied to the tub enables to communicate between thedrum 20 and the tub via the perforatedholes 21. A laundry having been put in thedrum 20 is lifted up by thetumbling ribs 25 to fall down when thedrum 20 rotates, whereby a sufficient amount of frictional and shock energy is provided for washing. - An
entrance 11, as shown in FIG. 1, is provided on a front side of thecabinet 10 so that a user puts or pull the laundry in/out of thedrum 20 and, adoor 14 is provided to open/close theentrance 11. Moreover, acontrol panel 15 for controlling the washing machine is provided on thecabinet 10. A non-explained numeral ‘13’ indicates a detergent box assembly for storing a detergent. - Referring to FIG. 2 and FIG. 3, a filter assembly for filtering particles in water is provided in a lower inside of the
cabinet 10. The filter assembly includes afilter case 31, afilter 35, and afilter cover assembly 40. Thefilter cover assembly 40 is explained in detail by referring to FIG. 2 and FIG. 3 as follows. - First of all, the
filter case 31, as shown in FIG. 2, is provided on an internal bottom of thecabinet 10. Abellows 51 connected to a drain (not shown in the drawing) of the tub is connected to thefilter case 31, whereby water in the tub flows in thefilter case 31. - A
circulation pump 52 and adrain pump 54 are connected to thefilter case 31. Acirculation hose 53 having one end connected to an upper side of the tub is connected to thecirculation pump 52, and adrain hose 55 having one end communicating with an outside of thecabinet 10 is connected to thedrain pump 54. - Hence, when the
circulation pump 52 pumps the water in the tub during washing, the pumped water moves to the upper side of the tub via thecirculation hose 53 and then falls down into thedrum 20. Energy generated from such a falling improves a washing power. When thedrain pump 54 pumps the water after completion of washing, the pumped water is discharged outside thecabinet 10 via thedrain hose 55. - The
filter 35, as shown in FIG. 2 and FIG. 3, is detachably loaded in thefilter 35. A multitude ofapertures 35 a are provided in thefilter 35, and plays a role in filtering the particles involved in the water flowing in thefilter case 31 by being pumped by the circulation ordrain pump filter 35 instead of theapertures 35 a. - Since the particles are gathered/attached in/to the
filter 35 in using the washing machine, thefilter 35 should be periodically cleaned or replaced. In order to load the filter in or out of aninsertion hole 31 c of thefilter case 31, afilter hole 17 is provided on one side of thecabinet 10. And, afilter cover assembly 40, as shown in FIG. 1 and FIG. 3, is provided to open/close thefilter hole 17. - Referring to FIG. 3, the
filter cover assembly 40 includes acover 41, a plurality ofprotrusions 43 at a lower end of thecover 41, and ahook 45 at an upper portion of thecover 41. - The
cover 41, as shown in FIG. 1, is fitted to thefilter hole 17 to cover. A plurality of theprotrusions 43 extend from the lower end of thecover 41 downward. The providedprotrusions 43 are inserted in a plurality of correspondingholes 31 a provided in a lower front side of thefilter case 31, respectively. And, thehook 45 protrudes from a center of the upper portion of thecover 41 toward thefilter case 31. The providedhook 45 is inserted in ahook hole 31 b provided at the upper front side of thefilter case 31. - The above-constructed washing machine according to the first embodiment of the present invention operates as follows.
- First of all, a laundry is put in the
drum 20, thedoor 14 is closed, and the washing machine is actuated to supply water and detergent to the tub. The detergent and water supplied to the tub flow in thedrum 20 via the perforated holes 21. - Once the
drum 20 rotates, the laundry is lifted up by the tumblingribs 25 to fall down for washing. In this case, thecirculation pump 52 pumps the water flowing in thefilter case 31 via thebellows 51 to thecirculation hose 53. The water then moves to an upper part of the tub via thecirculation hose 53 and then falls down into thedrum 20 to increase washing power. Meanwhile, thefilter 35 filters particles included in the water flowing in thefilter case 31 during such a washing step. - After completion of washing, the
drain pump 54 is actuated so that the water flowing in thefilter case 31 via thebellows 51 is discharged outside via thedrain hose 55. Meanwhile, during the draining step, thefilter 35 filters the particles included in the water flowing in thefilter case 31. - After completion of draining, water is supplied to the tub and the
drum 20 and thedrum 20 is then rotated to rinse the laundry. After rinsing the laundry, thedrain pump 54 is actuated to discharge the water in the tub outside. After such a rinsing step is repeated several times, thedrum 20 is rotated at high speed to dewater the laundry. - Meanwhile, after long time use of the washing machine, massive particles are attached to the
filter 35 so that it is unable to circulate or discharge the water smoothly. Hence, thefilter 35 is unloaded from thefilter case 31 so as to be cleaned or replaced. Such a procedure is explained as follows. - First of all, an upper side of the
cover 41 is pulled to separate thehook 45 from thehook hole 31 b. Thecover 41 is then turned centering on theprotrusions 43 inserted in thehole 31 a as a central axis, whereby thefilter hole 17 is wide open. - Once the
filter hole 17 is opened, thefilter 35 is grabbed to be unloaded from thefilter case 31. Thefilter 35 is cleaned or replaced by a new one so as to be inserted in theinsertion hole 31 c of thefilter case 31. - Once the cleaned or replaced
filter 35 is loaded, thecover 41 is turned by taking theprotrusions 43 inserted in theholes 31 c as a central axis and thehook 45 is then fitted to thehook hole 31 b to be fixed thereto. As thehook 45 is fixed to thehook hole 31 b and theprotrusions 43 are inserted in the correspondingholes 31 a, thecover 41 is completely installed. - The washing machine equipped with the above-constructed
filter cover assembly 40 according to the first embodiment of the present invention facilitates to open thecover 41 for user's convenience. - Yet, only one
hook 45 for fixing the upper side of thecover 41 is provided at the upper center of thecover 41. Hence, upper right and left sides of thecover 41, as shown in FIG. 1, are unable to be completely fixed but protrude out of a front side of thecabinet 10, whereby a step and a gap lie between thecover 41 and the front side of thecabinet 10 to spoil the exterior beauty. - Moreover, only one
hook 45 fixes thecover 41 to exert a weak fixing power thereon. And, if thecover 41 is numerously separated, thehook 45 is broken. - Therefore, a second embodiment of the present invention is provided to overcome such problems. A second embodiment of the present invention provides a modified filter cover assembly enabling to overcome all the problems of the filter cover assembly according to the first embodiment of the present invention. A washing machine according to a second embodiment of the present invention is explained in detail by referring to FIG. 4 to FIG. 8.
- In describing a washing machine according to a second embodiment of the present invention compared to that according to the first embodiment of the present invention in FIG. 1 to FIG. 3, like elements are indicated using the same or similar reference designations where possible throughout the drawings. Moreover, elements or structures different those of the first embodiment of the present invention are explained in the following to avoid repetition of description.
- Referring to FIG. 6 and FIG. 8, a
filter cover assembly 100 of a washing machine according to a second embodiment of the present invention includes acover 110,protrusions 120, and hooks 130. In the second embodiment of the present invention, theprotrusions 120 and thehooks 130 are provided plurally at upper and lower sides of thecover 110. Specifically, there are provided threeprotrusions 120 and threehooks 130. - Referring to FIG. 5, a plurality of
holes 31 a, and more specifically, threeholes 31 a are provided at a lower front side of thefilter case 31 so that theprotrusions 120 are inserted to be coupled. Specifically, threeholes 31 a penetrate into central, right, and left lower front sides of thefilter case 31, respectively. Moreover, a plurality of hook holes 31 b, and more specifically, threehook holes 31 b are provided at an upper front side of thefilter case 31. Specifically, threehook holes 31 b penetrate into central, right, and left upper front sides of thefilter case 31, respectively. - Meanwhile, the
cover 110, as shown in FIG. 4, is fitted to thefilter hole 17 provided at thecabinet 10 to cover thefilter hole 17. And, theprotrusions 120, as shown in FIG. 6 and FIG. 8, extend from the central, right, and left lower sides of thecover 110, respectively. In the second embodiment of the present invention, at least one of theprotrusions 120 has a structure unable to be detached from the correspondinghole 31 a after insertion, which is explained in the following. - Referring to FIG. 6 and FIG. 8, at least one of the
protrusions 120, e.g., first andthird protrusions slit barb - At least one of the
slits third protrusions protrusions 120, i.e., vertically. If theslits third protrusions third protrusions barbs protrusions 120. Meanwhile, asecond protrusion 122 at the central lower side of thecover 110 fails to be provided with the slit and barb. Yet, the slit and bard can be provided to thesecond protrusion 122 as well. - The above-constructed
protrusions 120 are fitted to theholes 31 a of thefilter case 31 to be fixed, respectively. In this case, both lateral sides of the first andthird protrusions holes 31 a and then elastically restored outward. Thus, once theprotrusions 120 are completely fitted to the correspondingholes 31 a, thebarbs protrusions 120 from being separated from theholes 31 a. Hence, a user makes use of theprotrusions 120 inserted in theholes 31 a as a kind of hinge-shaft, as shown in FIG. 7, to turn thecover 110 for closing or opening thefilter hole 17. - Meanwhile, the
hooks 130 protrude from central, right, and left upper sides of thecover 110 toward thefilter case 31, respectively. Such each of thehooks 130 includes anextension part 131, anelastic part 132, and abarb 133. - The
extension part 131, as shown in FIG. 8, protrudes from the upper side of thecover 110 toward thefilter case 31. And, theelastic part 132 is bent from an end of theextension part 131 toward thecover 110. Theelastic part 132 lies over theextension part 131, and a predetermined gap is provided between the elastic andextension parts elastic part 132 can be elastically deformed upward and downward. Meanwhile, thebarb 133 of thehook 130, as shown in FIG. 8, protrudes from a top of theelastic part 132. The protrudingbarb 133 is inserted in thecorresponding hook hole 31 b when thefilter hole 17 is covered with thecover 110. - Each of the
hooks 130 may further include apush piece 134 facilitating a user to push. Thepush piece 134, as shown in FIG. 8, extends from an end of theelastic part 132. Hence, if a user pushes thepush piece 134 while thebarb 133 is inserted in thehook hole 31 b, thebarb 133 is released from thehook hole 31 b so as to facilitate the user to open thecover 110. - Meanwhile, it is preferable that there is no step difference between the upper side of the
hook 130 and the upper end of thecover 110 to improve the exterior beauty. Hence, thehook 130, as shown in FIG. 8, preferably extends from agroove 111 provided on the upper end of thecover 110. In other words, the upper end of thecover 110 in the vicinity of a portion where thehook 130 is provided protrudes as high as the upper side of thehook 130. With such a structure, thecover 110 enables to entirely cover thefilter hole 17, thereby improving the exterior beauty more. - In using the above-structured
filter cover assembly 100, theprotrusions 120 are firstly inserted in theholes 31 a of thefilter case 31. Once theprotrusions 120 are completely inserted, thebarbs protrusions 120 from being separated from theholes 31 a. - If the upper side of the
cover 110 is pushed toward thefilter case 31 while such a state is maintained, thecover 110 is turned by taking theprotrusions 120 inserted in theholes 31 a as a rotational axis. As thecover 110 is turned, thehooks 130 are inserted in thefilter hole 17. If thebarbs 133 of thehooks 130 are finally inserted in the hook holes 31 b of thefilter case 31, thefilter cover assembly 100 is completely loaded. - Once the
filter cover assembly 100 is completely loaded, the threehooks 130 and the threeprotrusions 120 are instead in the hook holes 31 b and theholes 31 a, respectively to be fixed. Hence, the outer surface of thecover 110 lies in the same plane of the outer surface of thecabinet 10. Hence, there is no step difference to improve the exterior beauty. Besides, as the threehooks 130 are fixed, thefilter cover assembly 100 is securely loaded. - Meanwhile, in order to clean or replace the
filter 31 after long time use, thepush piece 134 of thehook 130 is pushed. Thebarb 133 is then released from thecorresponding hook hole 31 b. If the user pulls the upper side of thecover 110, thecover 110 is turned by taking theprotrusions 120 inserted in theholes 31 a as a hinge shaft. Once thecover 110 is fully turned, thecover 110 is not completely separated from thecabinet 10 since theprotrusions 120 maintain to be inserted in theholes 31 a, respectively. - While the
cover 110, as shown in FIG. 7, is open, the user draws out thefilter 31 from thefilter case 31 and then cleans thefilter 31 or replaces it by a new one. Then the cleaned or new filter is inserted in thefilter case 31 to be loaded. Once thefilter 31 is loaded, theuser 110 turns thecover 110. When thecover 110 is fully turned, thebarbs 133 of thehooks 130 are inserted in the hook holes 31 b, respectively so that thecover 110 is completely fixed. - As mentioned in the foregoing description, the user cleans or replaces the
filter 31 after opening thecover 110 with ease and then reloads it with ease. - Accordingly, the washing machine according to the second embodiment of the present invention has the following advantages or effects.
- First of all, since three protrusions and hooks fix the lower and upper ends of the cover, the filter cover assembly can be securely loaded in the filter hole of the cabinet.
- Secondly, since three protrusions and hooks fix the lower and upper ends of the cover, there is no step difference between the outer surfaces of the cover and cabinet. Therefore, the exterior beauty of the washing machine is improved.
- Thirdly, as the push pieces are provided on the hooks, the user opens the cover conveniently and easily to clean or replace the filter.
- It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover such modifications and variations, provided they come within the scope of the appended claims and their equivalents.
