The apparatus for treating clothes according to the present invention further includes a drum support portion H which is fixed to the drum 3 through a repulsive force between a magnetic unit provided on the tub and a magnetic unit provided on the drum, To the inside of the tub (2).

That is, the drum supporting portion H includes a tub magnetic unit 51 provided on the circumferential surface of the tub 2, a drum magnetic unit provided on the circumferential surface of the drum 3 and having the same magnetic pole as the tub magnetic unit 52).

The tub magnetic unit 51 and the drum magnetic unit 52 may be provided as permanent magnets and the tub magnetic unit 51 may be disposed on the inner circumferential surface TI of the tub 2 or the outer circumferential surface TO The drum magnetic unit 52 is provided with N poles 511 and S poles 512 on the outer circumferential surface DO or the inner circumferential surface DI of the drum, ) And an S-pole (522).

In this case, it is preferable that the tub magnetic unit 51 and the drum magnetic unit 52 are arranged such that the same magnetic pole faces the drum 3 so that the drum 3 can float due to the repulsive force between the two permanent magnets.

2, when the tub magnetic unit 51 is discontinuously disposed along the circumferential surface of the tub 2 as shown in FIG. 2, the drum magnetic unit 52 is continuously provided along the circumferential surface of the drum 3 .

However, if the tub magnetic unit 51 is continuously provided along the circumferential surface of the cylindrical tub 2, the drum magnetic unit 52 may be disposed discontinuously along the circumferential surface of the drum 3 It is acceptable.

When the tub magnetic unit 51 is provided discontinuously along the circumferential surface of the tub 2, the tub magnetic unit 51 is formed such that a button-shaped (cylindrical) permanent magnet is spaced apart from the circumferential surface of the tub by a predetermined distance .

The drum magnetic unit 52 continuously provided along the circumferential surface of the drum may be provided with a bar-shaped permanent magnet wound on the circumferential surface of the drum.

Meanwhile, the tub magnetic unit 51 and the drum magnetic unit 52 according to the present invention may have the structure of FIGS. 3 to 6.

3, the tub magnetic unit 51 may be fixed to the outer circumferential surface (FIG. 3A) of the tub 2 or the inner circumferential surface of the tub (FIG. 3B) (FIG. 3 (c)) on the circumferential surface of the tub 2, as shown in FIG.

In this case, the drum magnetic unit 52 is preferably fixed to the outer circumferential surface of the drum 3, but the drum magnetic unit 52 may be fixed to the inner circumferential surface of the drum 3, It is not exempted from the case of being inserted and fixed on the main surface.

In any case, the tubular magnetic unit 51 and the drum magnetic unit 52 should be arranged such that the same magnetic poles face each other.

The drum supporting portion H provided in the present invention includes a vibration attenuating unit 55 for suppressing the vibration of the tub magnetic unit 51 by the magnetic force provided to the tub magnetic unit 51 when the drum 3 vibrates, As shown in FIG.

The vibration damping unit 55 may be fixed to the tub magnetic unit 51 as shown in Fig. 3 (a) and may be located between the cabinet 1 and the tub magnetic unit 51, And may be fixed to the inner circumferential surface of the tub 2 to support the tub magnetic unit 51 as shown in FIG.

3 (c), when the tub magnetic unit 51 is inserted and fixed on the circumferential surface of the tub 2, the vibration attenuation unit 55 vibrates the inner circumferential surface of the tub 2 and the inner circumferential surface of the tub 2, Unit 51 as shown in Fig.

That is, when the tub magnetic unit 51 is inserted into and fixed to the circumferential surface of the tub 2, it is preferable that the cylindrical surface of the tub 2 includes an insertion hole 25 into which the tub magnetic unit 51 is inserted The vibration damping unit 55 may be provided inside the insertion hole 25 to support the tub magnetic unit 51.

When the distance between the drum magnetic unit 52 and the tub magnetic unit 51 is shortened due to the vibration of the drum 3, the repulsive force (strength of the magnetic force) between the drum magnetic unit 52 and the tub magnetic unit 51 increases The tub 2 will vibrate together when the drum 3 vibrates.

This is because the tubular magnetic unit 51 is fixed to the tub 2 so that the repulsive force that the drum magnetic unit 51 provides to the tubular magnetic unit 51 can be transmitted to the tub 2. [

However, since the vibration damping unit 55 is positioned between the tub magnetic unit 51 and the tub 2, the apparatus 100 for treating clothes of the present invention can minimize the transmission of the vibration of the drum 3 to the tub 2 (Figs. 3 (b) and 3 (c)).

FIG. 4 shows another embodiment of the drum supporting portion H of the present invention. The drum supporting portion H according to the present embodiment is further provided with a magnetic force amplifying unit 56.

As shown in FIG. 5, it is experimentally confirmed that when a metal such as iron is placed on either one of the N pole and the S pole of the permanent magnet, the magnetic force of the magnetic pole without the metal increases.

In the case of bar-shaped magnets, the magnetic force of the N and S poles is 295mT and 287mT, but when the metal is placed at the S pole, the magnetic force of the N pole increases to 330mT and the magnetic force of the S pole increases And it decreases to 97mT. It can be seen that the increase of the magnetic force of the N pole is smaller than the increase of the magnetic force when the two magnets are overlapped but is useful for increasing the magnetic force of the N pole provided in one magnet.

On the other hand, in the case of a cylindrical magnet, the magnetic force of the N pole increases from 463 mT to 500 mT and the magnetic force of the S pole decreases from 462 mT to 245 mT when the metal is positioned at the S pole.

The magnetic force amplifying unit 56 reduces the magnetic force emitted from the S pole 512 of the tub magnetic unit 51 and the S pole 522 of the drum magnetic unit 52, It is possible to prevent the electronic device inside the clothes processing apparatus from malfunctioning due to the magnetic force provided by the tub magnetic unit and the drum magnetic unit.

Further, since the magnetic force directed toward the inside of the drum 3 is reduced by the magnetic force amplifying unit 56, it is also possible to prevent the magnetic body in the laundry from coming into close contact with the inner peripheral surface of the drum 3.

On the other hand, the magnetic force amplifying unit 56 may be provided in the form of FIG. 4 (b) or FIG. 4 (c).

The first magnetic unit 71 may be a permanent magnet provided on the housing body 791 and provided with an N pole 711 and an S pole 712. The second magnetic unit 73 may include a permanent magnet Permanent magnets (N poles 731 and S poles 732) provided on the back surface of the tub and providing attraction force to the first magnetic unit 71 may be provided.

In this case, the second magnetic unit 73 is formed of a permanent magnet having a shape such as a disk or a ring, and the first magnetic unit 71 may have a plurality of permanent magnets spaced apart from each other by a predetermined distance.

In particular, as shown in FIG. 7, the first magnetic unit 71 fixed to the housing body 791 has a plurality of permanent magnets spaced apart from each other along the circumference of the second magnetic unit 73 .

The first magnetic unit 71 may be fixed to the surface of the housing body 791 and the second magnetic unit 73 may be fixed to the rear surface of the tub, .

That is, the first magnetic unit 71 is inserted into the housing body 791, and the second magnetic unit 73 is inserted into the back surface of the tub. This is to prevent an increase in the volume of the cabinet 1 by minimizing the distance between the back surface of the tub and the housing body 791. [

The spacer 75 may be provided as a ball slider provided on the housing body 791 or the rear surface of the tub. The ball slider may include a ball holding portion 751 fixed to the housing body 791 And a ball 753 rotatably coupled to the ball support and contacting the back surface of the tub.

The magnetic force amplifying unit provided in the driving part supporting part 7 includes a housing first magnetic force amplifying unit 72 provided in the housing body 791 and supporting the first magnetic unit 71, And a housing second magnetic force amplifying unit (74) for supporting the magnetic unit (73).

In order to more stably support the bearing housing 79, the cabinet 1 may further include a housing support portion 15 (see FIG. 1) provided at a predetermined distance from the back surface of the tub.

In this case, the bearing housing 79 will be located in a space formed between the housing support 15 and the rear surface of the tub. The spacer includes a first spacer 75 for maintaining a space between the rear surface of the tub and the housing body 791, a second spacer 75 for maintaining a space between the housing body 791 and the housing support 15, (752).

Further, when the housing support 15 is provided in the cabinet, the housing body 791 is provided with a third magnetic unit A and a housing third magnetic force amplifying unit (not shown) A fourth magnetic unit B and a housing fourth magnetic force amplifying unit (not shown) for providing a force to the third magnetic unit.

[ Accordingly, the driving unit 6 can be assembled or disassembled into the housing body 791 through the support through-hole 151.

It is preferable that the diameter of the support through hole 151 is larger than the maximum amplitude of the rotor 61 vibrating together with the drum when the drum 3 rotates.

The garment treating apparatus 100 having the above-described structure can minimize the transmission of the vibration generated in the drum 3 to the tub by the drum supporting portion H and the driving portion supporting portion 7. [

1, the circumferential surface of the drum 3 is maintained in a floating state in the tub 2 by the tub magnetic unit 51 and the drum magnetic unit 52, The driving unit 6 coupled to the drum 3 and fixed to the bearing housing 79 is maintained in a floating state inside the cabinet 1 by the first magnetic unit 71 and the second magnetic unit 73. [

On the other hand, when the drum 3 vibrates inside the tub 2 (when the drum moves along the height direction of the tub or in the width direction of the tub), the drum 3 is rotated by the drum magnetic unit 51, The unit 52 is prevented from colliding with the inner circumferential surface of the tub 2 due to the repulsive force.

The driving unit 6 vibrates together with the drum when the drum 3 is vibrated by the rotating shaft 65 connected to the drum but the bearing housing 79 to which the driving unit 6 is fixed is rotated by the first magnetic unit 71, And the second magnetic unit 73 can maintain a constant height from the bottom surface of the cabinet.

Therefore, even if the drum 3 vibrates inside the tub 2, the driving unit 6 provided in the present invention can maintain a certain distance from the back surface of the tub 2 by the spacer 75, The first magnetic unit 71 and the second magnetic unit 72 can maintain a constant height from the bottom surface of the cabinet.

In conclusion, the garment processing apparatus of the present invention can reduce the vibration generated in the drum 3 by the repulsive force between the tub magnetic unit 51 and the drum magnetic unit 52, the repulsive force between the first magnetic unit 71 and the second magnetic unit 73 Is absorbed by the gravity of the structure.

The rotary shaft 65 of the driving unit of the present invention is inserted into the tub through hole 27 having a diameter larger than the diameter of the rotary shaft 65 and is connected to the drum 3, And is located inside the support through-hole 151.

The diameter of the tub through hole and the diameter of the support through hole are such that even if the maximum displacement (displacement in which the drum and the tub collide with each other) occurs in the drum 3, the rotary shaft 65 and the rotor 61 penetrate through the tub through- The vibration of the drum can be prevented from being transmitted to the tub by the rotary shaft 65 even if the drum 3 vibrates inside the tub.

Therefore, the clothes processing apparatus of the present invention has the effect of providing a clothes processing apparatus in which vibration and noise are reduced since the vibration generated during rotation of the drum 3 is not transmitted to the tub 2 through the rotary shaft 65.

Since the vibration of the tub 2 can be minimized, the clothes processing apparatus 100 of the present invention can maximize the volume of the tub 2 located in the cabinet 1 having the same volume (maximize the washing capacity) You can expect.

It is indispensable to provide a space between the tub and the cabinet for preventing the cabin from colliding with the tub when the drum rotates in the conventional clothes processing apparatus. The tub 2 can be minimized or separated from the vibration system, so that the volume of the tub 2 positioned in the cabinet 1 having a certain volume can be maximized.

FIG. 9 shows another embodiment of the clothes processing apparatus 100 of the present invention. The present embodiment is characterized in that the structure of the driving part support 7 is different from that of the embodiment of FIG.

Therefore, the following description will be made on the basis of the driving part support 7 distinguished from the embodiment of Fig.

The driving part supporting part 7 according to the present embodiment includes a bearing housing 79 which is provided outside the tub 2 and on which the driving part 6 is supported and a bearing housing 79 for fixing the bearing housing 79 to the back surface of the tub, And a slider unit (76, 77, 78) for allowing the spring (79) to flow in the radial direction with respect to the back surface of the tub.

The slider unit includes a slider body 76 provided between the rear surface of the tub and the bearing housing 79 and a slider body 76 fixed to the rear surface of the tub, A first guider 77 which reciprocates along a width direction of the tub and a height direction of the tub, and a second guider 77 that fixes the bearing housing 79 to the slider body 76, And a second guider 78 which makes it possible to reciprocate along the second direction (the width direction of the tub and the other one direction of the height direction of the tub).

The slider body 76 includes a body through hole 761 and the diameter of the body through hole 761 is larger than the diameter of the rotation shaft 65. It is preferable that the diameter of the body through hole 761 is set so that the rotation axis 65 does not collide with the body through hole 761 even when the drum 3 is fully displaced.

The first guider 77 includes a first rail 771 provided on one of the slider body 76 and the rear surface of the tub, the slider body 76 and the other of the rear surfaces of the tub, And a first rail receiving portion 773 in which the first rail 771 is accommodated.

In this case, the first rail 771 may be provided along the width direction of the tub on the rear surface of the tub 2 as shown in FIG. 9, or may be provided on the rear surface of the tub 2 as shown in FIG. And may be provided along the height direction of the tub.

The second guider 78 includes a second rail 781 provided on one of the slider body 76 and the bearing housing 79 and a second rail 781 disposed on one of the slider body 76 and the bearing housing 79 And a second rail receiving portion 783 provided in the second rail receiving portion 783 to receive the second rail 781. [

In this case, it is preferable that the second rail 781 is inclined at a predetermined angle with the first rail 771. In FIGS. 9 and 10, the first rail 771 and the second rail 781 intersect at right angles As an example.

9, since the slider body 76 is supported by the first rail 771 by the first rail receiving portion 773, the slider body 76 is supported by the first rail 771, Is prevented from moving toward the bottom surface of the cabinet 1 (toward the lower portion of the tub).

Since the bearing housing 79 is supported on the drum 3 via the rotary shaft 65 connected to the drum 3, the bearing housing 79 is moved toward the bottom surface of the cabinet by the drum supporting portion H .

10, the bearing housing 79 connected to the drum 3 via the rotary shaft 65 is positioned at a predetermined position by the drum supporting portion H . Accordingly, the slider body 76 connected to the bearing housing 79 through the second guider 78 can also maintain a constant position despite the slider body 76 itself.

9, the first rail 771 can support the weight of the slider body 76, so that the drum 771 having a small magnetic force can be supported by the first rail 771. Therefore, when the first rail 771 is provided along the width direction of the tub, The drum 3 and the bearing housing 79 can be supported by only the supporting portion H.

The tub 2 may further include a rear gasket 29 (see FIG. 10) for connecting the rear surface of the tub to the bearing housing 79, or the rear surface of the tub and the slider body 76.

The tub has a tub through hole (27) through which a rotary shaft (65) is inserted. Therefore, the rear gasket 29 is a means for preventing the washing water stored in the tub through the tub through-hole 27 from leaking, and also the driving part supporting part 7 provided on the back surface of the tub can maintain a predetermined position .

Meanwhile, the first rail 771 and the second rail 781 may be formed as a bar having a cylindrical shape as shown in FIG.

The drum 3 is held in the tub 2 by the tub magnetic unit 51 and the drum magnetic unit 52 in the garment treating apparatus 100 having the above-described structure, And the drive unit 6 fixed to the drum 3 via the rotary shaft 65 is fixed to the rear surface of the tub by the slider unit.

Therefore, when the drum 3 vibrates inside the tub 2 (when the drum moves along the height direction of the tub or in the breadth direction of the tub), the drum 3 is rotated by the tub magnetic unit 51 and the drum magnetic unit Is prevented from colliding against the inner circumferential surface of the tub (2) due to the repulsive force between the tub (52).

Since the bearing housing 79 to which the drive unit 6 is fixed is fixed to the rear surface of the tub through the slider unit, when the drum 3 vibrates along the height direction of the tub, the bearing housing 79 is rotated by the first guider 77 Or the second guider 78 and the drum housing 3 vibrates along the width direction of the tub when the drum housing 3 vibrates along the width direction of the tub and the bearing housing 79 is rotated by the first guider 77 or the second And will move along the width direction of the tub by the remaining one of the guiders 78.

The rotary shaft 65 of the driving unit is inserted into the tub through hole 27 and the body through hole 761 having a larger diameter than the diameter of the rotary shaft 65 and is connected to the drum 3, The diameter of the body through hole 761 and the diameter of the body through hole 761 are set such that the maximum displacement (displacement in which the drum and the tub collide with each other) is generated in the drum 3 even if the rotary shaft 65 is in contact with the tub through hole 27 and the body through hole 761 As shown in Fig.

Therefore, the clothes processing apparatus of the present invention has the effect of providing a clothes processing apparatus in which vibration and noise are reduced since the vibration generated during rotation of the drum 3 is not transmitted to the tub 2 through the rotary shaft 65.

The present invention may be embodied in various forms without departing from the scope of the invention.
