Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a wall-mounted washing machine and a door gasket,

The present invention relates to a wall-mounted type washing machine and a door gasket thereof.

A washing machine is a device for separating contaminants from washing cloths by using washing water and detergents. It separates contaminants from washing cloths by chemical action by detergent dissolved in washing water and mechanical action of washing water and inner basket can do. Such a washing machine may be divided into a top loading type washing machine, a front loading type washing machine, a combined type washing machine combined with a top loading type and a front loading type, depending on the method of loading laundry.

Recently, a wall-mounted washing machine that can be installed in a narrow space such as a bathroom or a toilet has been introduced. In general, a wall-mounted washing machine adopts a front loading method for miniaturization.

For example, a wall-mounted type washing machine includes a cabinet forming an outer appearance, a tub provided inside the cabinet for filling the washing water, a drum rotatably installed inside the tub and accommodating the laundry, a driving unit for supplying power to the drum, A water supply device for supplying wash water to the tub, and a drain device for discharging the wash water from the tub to the outside of the cabinet.

The conventional wall-hung type washing machine is provided with a gasket for simply maintaining watertightness. Here, the conventional gasket is mounted along the rim of the hole into which the laundry is introduced from the front panel of the washing machine. At this time, the outer surface of the mounting portion of the gasket comes in contact with the plastic material corresponding to the surface of the cover, and receives vibration due to the operation of the washing machine.

However, in the conventional washing machine, there is a contact between the mounting portion (e.g., rubber material) of the gasket and the release material such as the plastic material.

Particularly, when vibration is transmitted in the contact state between the release materials, there is a problem that chemical cracks are generated in the gasket having a relatively lower strength than the plastic material on the chemical contact portion between the release material.

In the conventional washing machine, there is no countermeasure against gasket damage due to chemical cracks. As a result, the water-tightness of the washing machine deteriorates due to the breakage of the gasket.

The rear panel 800 may include a control unit 810 for controlling the overall function of the wall-mounted type washing machine 10 and a drain unit 820 for discharging the washing water dewatered in the tub 700. [

The control unit 810 is provided on the front surface of the rear panel 800 and can control various components of the wall-mounted type washing machine 10 according to a user's operation to perform washing. Although the control unit 810 is shown on the right side of the tub 700 as an example in the present embodiment, the position of the control unit 810 is not limited thereto.

The power supply line 904 may be connected to an external power source to supply power to the above-described electric equipment, the control unit 810, the drive motor 910, and the like. The power supply line 904 may extend through the rear panel 800 to the front of the rear panel 800 and may extend outward from the rear surface of the rear panel 800. [ At this time, the power supply line 904 may be fixed to the rear surface of the rear panel 800 through a separate fixing means. Since the power supply line 904 is provided extending from the rear surface of the rear panel 800 to the outside, the appearance of the washing machine 10 can be finely finished.

A drain unit 820 may be provided at a lower portion of the rear panel 800. [ The drainage unit 820 discharges the wash water in the tub 700 to the outside, and may be provided on the lower front side of the rear panel 800. At this time, the drain unit 820 may include a drain pump for pressurizing the wash water, and may be connected to the drain hose 902 to discharge the wash water. Specifically, the drainage hose 902 is connected to the drainage unit 820 and extends outward along the rear surface of the rear panel 800, so that the wash water can flow through the pressure of the drainage unit 820. Therefore, when the drainage unit 820 is operated after the washing process is finished, the wash water can be discharged to the outside of the cabinet 100 through the drainage hose 902 due to the pressure change of the drainage unit 820.

The rear panel 800 includes a driving motor 910 for transmitting driving force, a first pulley 912 and a second pulley 914 connected to the driving motor 910, and a second pulley 914 connected to the rear panel 800 A drum rotational shaft 916 for rotating the drum 600 and a belt 918 for connecting the first pulley 912 and the second pulley 914.

In summary, when all the washing water is drained to the tub 700 through the fitting 440, the control unit 810 can operate the driving motor 910. At this time, the first pulley 912 connected to the driving motor 910 is rotated, and the second pulley 914 can be rotated by the rotation of the first pulley 912. The drum rotation shaft 916 connected to the second pulley 914 is also rotated so that the drum 600 can be rotated inside the cabinet 100 and the tub 700. [ That is, the laundry inside the drum 600 can be washed.

On the other hand, the rear panel 800 may further include an exhaust line 920. The exhaust line 920 is connected to the drainage unit 820 and can discharge the air inside the tub 700 and the drainage unit 820. Specifically, the exhaust line 920 is connected to the drain hose 902 and can pass through the rear panel 800, thereby extending to the rear surface of the rear panel 800 and allowing exhaust to the outside.

The above-described wall-mounted type washing machine 10 according to an embodiment of the present invention can be used as follows.

First, the user can open the door 200, put laundry into the drum 600, and take out the detergent container 500 from the front panel 400. At this time, the center of the detergent case 500 is partitioned, and a space can be provided in which the detergent and the softening agent can be separately introduced.

After inserting the detergent container 500 into which the detergent and the softening agent have been introduced into the front panel 400 again, the user closes the door 200 and controls the washing operation through the power button 102 and the display 202 . When the washing operation is started, the wash water supplied from the external water source through the water supply valve assembly 480 can be supplied to the detergent dispenser 500 through the fitting 440, and the wash water is supplied to the detergent dispensing space 504 and / The water can be supplied to the inside of the drum 600 and the tub 700 after passing through the softening agent introducing space 506. That is, detergents and softeners may be selectively contained in the washing water that is dewatered to the drum 600 and the tub 700.

When all of the washing water is filled in the tub 700, the control unit 810 can drive the driving motor 910. Since the driving motor 910 can be connected to the first pulley 912 and the second pulley 914 and the second pulley 914 can be connected to the drum 600 through the drum rotation shaft 916, The drum 600 can be rotated through the motor 910.

FIG. 5 is a front view of the washing machine of FIG. 1, FIG. 6 is a sectional view taken along the line V-V of FIG. 5, and FIG. 7 is an exploded perspective view of a front panel to which the cover of FIG. 4 is coupled. 8 is an enlarged cross-sectional view taken along the line VII-VII shown in FIG. 7, and FIG. 9 is an enlarged cross-sectional view of the circle M shown in FIG.

5 to 9, the front panel 400 includes a plurality of coupling protrusions 411 for bolt coupling to be coupled to the end of the tub 700, 410).

Here, the opening 460 is integrally formed on the inner edge of the shield 410.

The opening 460 may be an annular wall structure extending vertically from the surface of the shield 410. For example, the openings 460 may have stepped cross-sections along different diameters in the annular wall.

More specifically, the opening portion 460 includes an annular wall portion 461 extending from the inner edge of the shield portion 410 toward the cover 300, and an annular wall portion 461 formed at an end of the annular wall portion 461, And an annular end 462 having a diameter smaller than the diameter of the annular wall portion 461.

The annular end portion 462 may mean a step formed at the end position of the annular wall portion 461.

Referring to FIG. 7, a plurality of protrusions 463 are formed at the annular end 462.

The plurality of protuberances 463 may be spaced apart in the circumferential direction of the annular end 462.

Each of the protrusions 463 extends in the circumferential direction on the outer peripheral surface of the annular end portion 462 and protrudes in the radial direction of the annular end portion 462 to prevent the door gasket 450 from being separated .

The annular end 462 of the opening 460 may be the support base of the door gasket 450. For example, the door gasket 450 is supported on the annular end portion 462 to act on the door glass 280 of the door 200 or the inclined surface 281 of the door glass 280, which will be described later.

The door gasket 450 may be a ring-shaped elastic structure extending in the circumferential direction corresponding to the shape of the opening 460.

When the door 200 is closed, the door gasket 450 bends in a range of elasticity when it contacts the door glass 280 of the door 200, thereby generating a bending force.

The door gasket 450 may be formed of an elastic material, a rubber material, or a silicone material.

For example, the door gasket 450 may be made of fluoro elastomers, epichlorohydrin polymer, ethylene propylene monomer (EPM), ethylene propylene diene monomer (EPDM), isobutylene isoprene rubber (IIR) And hydrogenated nitrile butadiene rubber (HNBR), or the like.

2, the door 200 is in an open state. According to the opened state of the door 200, the door 200 is rotated in a direction away from the cabinet 100 with respect to the door hinge 360. At this time, the door locking unit 260 is released from the door locking unit 330 and is released. Further, the end of the door opening unit 250 is in a state of being protruded by an elastic force of a spring provided inside the door opening unit 250.

In this case, the elastic projection 455a of the door gasket 450 indicated by a dotted line in Fig. 9 may be in a state of not contacting the door glass 280. [ For example, in the pre-elastic deformation state, the elastic projection 455a may be inclined toward the door 200 as shown.

On the other hand, referring to FIG. 1, the door 200 is in the closed state. According to the closed state of the door 200, the door 200 is reversely rotated in the direction toward the cabinet 100 with respect to the door hinge 360. At this time, the door locking unit 260 is locked to the door locking unit 330. The end of the door opening unit 250 is in contact with the bottom surface of one side of the cover 300 and then is retracted toward the inner space of the door inner frame 230 while compressing the spring.

In this case, the elastic projection 455 of the door gasket 450 indicated by the solid line in FIG. 9 may be elastically deformed as it contacts the door glass 280 and bends toward the drum 600. At this time, the elastic projection 455 has a bending force within the elastic deformation range.

Again, the user may press the door opening button 210 of the electronic opening and closing type to make the door 200 open as described above.

That is, the door locking portion 260 in a locked state is released from the door locking unit 300. In this case, the door opening unit 250 applies the elastic force of the compressed spring to the bottom surface of the one side groove of the cover 300. As a result, the door opening unit 250 advances to the outside of the door inner frame 230 to cause a reaction to rotate the door 200.

The elastic protrusions 455 of the door gasket 450 apply a bending force to the door glass 280 in the same direction as the direction of the door of the door 200 so that the elastic protrusions 455a, The door 200 can be quickly opened.

That is, the door 200 can open the door 200 more smoothly and quickly by simultaneously using the elastic force of the spring inside the door opening unit 250 and the bending force of the elastic protrusion 455 of the door gasket 450 .

The door 200 is made of a rotatable material so that the force required to open the door 200 automatically or semi-automatically can be obtained not only from the door opening unit 250 but also from the elastic protrusion 455 of the door gasket 450 ).

The elastic protrusions 455 and 455a may function as a membrane spring of an elastic material extending along the circumferential direction of the door gasket 450. [

In order for the elastic protrusions 455 and 455a to function as a membrane spring, the inclined surface 281 of the door glass 280 should be formed to have a relatively large inclination angle as compared with the conventional drum type washing machine.

As a comparative example, the angle of inclination of the inclined surface (not shown) of the door glass of the conventional drum type washing machine is an angle of 30 whereas the inclination angle of the inclined surface 281 of the door glass 280 of the present embodiment Has an angle value selected within a range of an angle of 40 degrees to 50 degrees. The preferably optimized slope 281 may be formed at an angle of 45 degrees.

When the angle of inclination 281 of the door glass 280 is less than 40 degrees, the efficiency of transferring the bending force toward the door glass 280 may be significantly reduced. If the angle is more than 50 degrees, . Accordingly, the angle value of the slope 281 may have a critical meaning.

The door gasket 450 has elastic protrusions 455 and 455a and a gasket body portion 455a so as to more effectively operate the bending force of the elastic protrusions 455 and 455a on the inclined surface 281 of the door glass 280. [ 451, and further includes a waist portion 455b having a relatively thin thickness as compared with the elastic protrusions 455, 455a.

The waist portion 455b can serve as a pivot for easily rotating the elastic protrusions 455 and 455a located above the waist portion 455a in the door gasket 450 of a kind.

9, the inner circumferential surface 462a of the annular end portion 462 may extend parallel to the centerline of the wall-mounted type washing machine, for coupling with the door gasket 450. As shown in FIG.

The open portion 460 also has a step 464 located between the annular end 462 and the annular wall portion 461. 9, the step 464 serves to support the door gasket 450 and to form a stepped surface by connecting the annular end 462 and the annular wall 461 to each other. For this purpose, the stepped portion 464 is integrally formed in the opening portion 460.

The annular wall portion 461 extends in a section from the step portion 464 to the shielding portion 410 so as to be inclined downward with respect to the inner peripheral surface of the annular end portion 462. That is, the annular wall portion 461 may have a predetermined inclination angle B for improving the drainage performance.

The door gasket 450 is disposed between the cover 300 and the front panel 400 and has a stable mounting performance in order to smoothly perform the function of contacting the door 200 and maintaining watertightness And may be formed so as not to interfere with various types of reinforcing ribs formed on the front panel 400.

The door gasket 450 can be fixed primarily by the ring clamp 470.

The ring clamp 470 surrounds the outer side of the door gasket 450 and closely contacts the door gasket 450 toward the opening 460 of the front panel 400.

7, the ring-shaped clamp 470 includes an elastic wire 471 having a cross section and a ring shape corresponding to the seating portion 453 formed in the door gasket 450. As shown in Fig.

The ring type clamp 470 may include an annular portion 472 integrally formed at an end of the elastic wire 471 and a bolt and nut assembly 473 fitted to the annular portion 472. When the bolt and nut 473 are tightened using the tool, the circumferential length of the elastic wire 471 is reduced so that the door gasket 450 can be inserted into the annular end portion 462 of the opening portion 460 of the front panel 400, Lt; / RTI >

In addition, since a part of the door gasket 450 (for example, the gasket fixing portion 452) is positioned between the cover 300 and the annular end portion 462 of the front panel 400, The secondary fixing according to the coupling between the panels 400 can be performed. This secondary fixation further improves the installation of the door gasket 450. Here, since the secondary fixing directions are mutually intersected with respect to the primary fixing direction, the door gasket 450 can be more firmly fixed.

That is, the opening portion 460 includes an annular wall portion 461 extending from the inner rim of the shielding portion 410 toward the cover 300, and an annular wall portion 461 formed at the end of the annular wall portion 461, (464) connecting the annular end portion (462) and the annular wall portion (461) to each other so as to support the door gasket (450) And may be integrally formed by injection molding.

8, the door gasket 450 may include a gasket body portion 451, a gasket fixing portion 452, a seating portion 453, a front projection portion 454, and an elastic projection portion 455 .

The gasket body 451 may be disposed on the inner side of the opening 460 and may be bent in shape corresponding to the inner shape of the opening 460 of the front panel 400.

That is, the gasket body portion 451 is formed to be inclined corresponding to the shape of the annular wall portion 461 of the opening portion 460 for draining the fluid. For example, the gasket body portion 451 may have the same inclination angle B as the annular wall portion 461. [

The gasket fixing part 452 is integrally formed with the gasket body part 451 and is disposed outside the opening part 460 so as to surround the end of the opening part 460 of the front panel 400 .

The length of the gasket fixing portion 452 is formed to be shorter than the length of the gasket body portion 451 when the center line direction of the wall-mounted type washing machine is taken as a reference.

The seating portion 453 is formed on the outer peripheral surface of the gasket fixing portion 452 and serves to seat the ring-shaped clamp 470.

The front protruding portion 454 protrudes toward the edge of the laundry inlet 302 of the cover 300 at the end of the gasket fixing portion 452 and extends along the circumferential direction of the door gasket 450.

The elastic protrusions 455 have a wedge-shaped cross section that decreases in cross-sectional width as they extend toward the ends of the elastic protrusions 455.

The elastic protrusions 455 protrude obliquely toward the door 200 between the front protrusions 454 and the gasket body 451 and extend along the circumferential direction of the door gasket 450.

Particularly, the wall-mounted type washing machine has a door 200 installed on the cover 300 or more specifically on the door hinge 360 of the cover 300. The door 200 opens or closes the laundry inlet 302 of the cover 300. In particular, the door 200 has a door glass 280 bulged toward the drum 600.

In particular, the elastic protrusion 455 of the door gasket 450 protrudes toward the door 200, and contacts the door glass 280 to maintain watertightness.

The shape and inclined angle of the elastic protrusion 455 can be determined so as to be in contact with the inclined surface 281 of the door glass 280.

The gasket fixing portion 452 of the door gasket 450 contacts the annular end portion 462 corresponding to the end of the opening portion 460 of the front panel 400 and can be supported by the front panel 400. [ The gasket fixing portion 452 is extended from the gasket fixing portion 452 to the connection point between the front projection portion 454 and the gasket body portion 451 by a length corresponding to the thickness of the annular end portion 462 Gasket extension 456. In one embodiment,

In addition, the door gasket 450 has a plurality of walls 457, 458 to prevent foreign matter from entering. For example, the door gasket 450 includes a first foreign matter prevention wall 457 and a second foreign matter prevention wall 458 which extend along the circumferential direction and protrude from the inner circumferential surface of the gasket body portion 451, respectively. Here, the first foreign matter prevention wall 457 and the second foreign matter prevention wall 458 may be the foreign matter prevention means of the double structure for the washing machine of the present embodiment.

The first foreign matter prevention wall 457 may have a plurality of drain holes 457a formed therein. The drain hole 457a is formed in such a manner that water tinged in the first space S1 of the door gasket 450 is directed toward the second space S2 between the first foreign matter prevention wall 457 and the second foreign matter prevention wall 458 It can be a passage to escape.

The second foreign matter prevention wall 458 may have a cutout 458a formed at a position corresponding to the drain hole 457a. Here, the cutout portion 458a may mean a passage through which the water passing through the drain hole 457a passes.

The second foreign matter prevention wall 458 extends in the circumferential direction on the inner peripheral surface of the door gasket 450.

Particularly, the second foreign matter prevention wall 458 may be formed only on the lower inner peripheral surface of the door gasket 450.

When the second foreign matter prevention wall 458 is formed only on the inner peripheral surface of the lower side of the door gasket 450, the use amount of the material used for manufacturing the door gasket 450 is reduced while maximizing the foreign matter inflow preventing function, The assembly efficiency due to the weight reduction can be exhibited.

The second foreign matter prevention wall 458 may have a relatively low height as compared with the first foreign matter prevention wall 458 so as not to interfere with the drum entrance portion 610 of the drum 600.

The door gasket 450 is installed on the annular end portion 462 so that when the cover 300 and the front panel 400 are coupled to each other, The gap G1 may be maintained between the gasket extension portion 456 of the gasket extension portion 456. [

Although the vibration due to the operation is generated in the wall-mounted type washing machine by the gap G1, the door gasket 450 may not be chemically deformed or damaged, and chemical cracks may not be generated in the door gasket 450 .

The upper portion of the gap G1 is covered by the front projection 454. [

Therefore, water falling in the height direction (e.g., vertical direction) of the washing machine touches the front protruding portion 454 of the door gasket 450 during the wet laundry loading or while cleaning the inside of the washing machine with water, The pressure of the water may be lowered.

Due to this, the dropped water may hardly flow toward the gap G1. That is, this embodiment can perform the watertight function at the level of the living waterproof. That is, a water film or water of a minute water content can flow into the gap G1, but the inflow amount thereof can be very fine.

More specifically, the gap G1 of the door gasket 450 may be formed to extend between the surface of the cover 300 and the gasket fixing portion 452 of the door gasket 450.

The gap G1 of the door gasket 450 may be further extended between the surface of the cover 300 and the bottom surface of the front protrusion 454 of the door gasket 450.

The gap G1 may extend along the circumferential direction of the door gasket 450.

The gap G1 has a value selected from 0.01 mm to 0.3 mm based on the straight distance from the surface of the cover 300 to the door gasket 450. For example, the gap G1 does not generate a chemical crack at 0.2 mm, the chemical cracking rate at 0.2 mm or less can be increased, and at 0.2 mm or more, there is little chemical crack due to friction with a plastic material The water permeation amount can be increased sharply. Therefore, the numerical value of the gap G1 may have a critical meaning of 0.2 mm.

9, when the door gasket 450 is coupled to the annular end portion 462 of the opening portion 460 of the front panel 400, the end portion of the first foreign matter prevention wall 457 of the door gasket 450 And the inner circumferential surface of the drum inlet portion 610 may be the same.

Accordingly, the laundry can be easily introduced into the drum 600 by the first foreign matter prevention wall 457 and the drum inlet portion 610 having the same level (L).

The first foreign matter prevention wall 457 and the second foreign matter prevention wall 458 are spaced apart from each other with respect to the direction from the door gasket 450 toward the drum 600. [

In addition, when the user tries to put the laundry into the drum 600, the foreign matter separated from the laundry is separated into the first space S1 in the forward position of the first foreign body prevention wall 457 or the first foreign body prevention wall 457 And the second foreign matter prevention wall 458 in the second space S2. The movement of the foreign matter in the spaces S1 and S2 can be restrained by the first foreign matter prevention wall 457 or the second foreign matter prevention wall 458 and the outer peripheral surface of the drum inlet portion 610 and the door gasket 450 can be relatively minimized.

Further, an end of the drum inlet portion 610 is bent to form an outbound caulking portion 611.

The outbound caulking portion 611 is disposed in the second space S2 between the first foreign material prevention wall 457 and the second foreign material prevention wall 458. [

Therefore, the second space S2 can be a space such as an English U-shaped trap in which a foreign matter flow is very difficult, so that the inflow of foreign matter can be further blocked.

FIG. 10 is a sectional view of a door gasket according to an application example of the present invention, and FIG. 11 is a sectional view of a door gasket according to another application example of the present invention.

10 or 11, the door gasket 450a according to the application example includes a bead protruding from the outer surface of the door gasket 450a so as to come into contact with the inner side surface of the rim of the laundry inlet 302 of the cover 300, A portion 459 may be formed.

Here, the bead 459 serves to close the gap G1 between the surface of the cover 300 and the door gasket 450 as described above.

For example, the door gasket 450a is configured such that the cover 300 is coupled to the front panel 400 and the door gasket 450a is brought into contact with the surface of the cover 300. [

The cover 300 and the front panel 400 may be coupled by fastening means such as bolts connecting the cover 300 and the front panel 400 to each other. For example, when the bolts are loosened, the cover 300 and the front panel 400 can be separated from each other.

The bead portion 459 is a component of the door gasket 450a that is in contact with the surface of the cover 300. [

The end of the bead portion 459 is in line contact with the inner side surface of the rim of the laundry inlet 302 of the cover 300. Here, the line contact is a line shape in which the end of the bead portion 459 extends in the circumferential direction, and the contact between the line shape and the inner surface of the cover 300, that is, the inside edge of the laundry inlet 302 It can mean.

Therefore, even if the end of the bead portion 459 is partially damaged by the line contact, the structural strength of the remaining portion of the door gasket 450a can be maintained for a relatively long time.

That is, the bead portion 459 can be sacrificed to relatively extend the service life of the door gasket 450a, and can be a means for maintaining the structural safety of the entire door gasket 450a.

The bead portion 459 of the door gasket 450a is connected to the gasket fixing portion 452 facing the cover 300 from the gasket fixing portion 452 with reference to a position spaced downward from the front projection portion 454. [ 452, respectively.

The bead portion 459a of the door gasket 450b according to another embodiment shown in FIG. 11 is formed in the gasket extension portion 456 at a position spaced downward from the front protruding portion 454, 300 formed on the surface of the gasket extension 456.

The bead portions 459 and 459a of the door gaskets 450a and 450b have projecting heights corresponding to the intervals between the cover 300 and the door gaskets 450a and 450b.
