The tub inlet 23 is connected to the inlet 131 through the insulating portion 4, and a specific structure of the insulating portion will be described later.

The tub body 21 may be fixed inside the cabinet 1 through a tub support. As shown in FIG. 2, the tub support part has a spring 25 that fixes an area located above the horizontal line H passing through the rotation center of the drum among the circumferential surfaces of the tub body 21 to the cabinet 1 ), a region located under the horizontal line H among the circumferential surfaces of the tub body 21 may be provided as a damper for fixing the cabinet 1.

The damper includes a first damper 26 located on the left side of a vertical line V passing through the rotation center of the drum among the circumferential surfaces of the tub body 21, and a second damper located on the right side of the vertical line V. 27) may be provided to include.

The load unit has a first weight balancer 28 fixed in a space located to the left of the vertical line V among the spaces provided by the front surface of the tub body, and the vertical line ( It may be provided with a second weight balancer 29 fixed to the right side of V).

When the weight of the tub body 21 is increased through the load unit, the tub body 21 can absorb a greater vibration, so the present invention transmits the vibration generated when the drum 3 is rotated to the cabinet. It is possible to minimize that.

As shown in FIG. 1, the drum 3 includes a drum body 31 rotatable within the tub body 21. The drum body 31 is provided in a cylindrical shape with an empty inside, and a drum through hole 32 communicating the inside of the drum body with the inside of the tub body at the circumferential, front and rear surfaces of the drum body 31 Is equipped. In addition, a drum inlet 33 is provided on a surface of the space provided by the drum body 31 facing the inlet 11 (a front surface of the drum).

It is provided to include a rotor 353 positioned outside the body 21, a rotation shaft 355 that is provided to penetrate the rear surface of the tub body 21 and connects the rotor 353 and the drum body 31 Can be.

The insulating part 4 connecting the inlet 131 and the tub inlet 23 not only prevents the water stored in the tub body 21 from being discharged to the cabinet 1 through the tub inlet 23, but also , It is a means for attenuating the vibration of the tub body 21 from being transmitted to the cabinet 1.

As shown in FIG. 3, the insulating part 4 is provided with an elastic body (rubber, etc.) to include an insulating body 41 connecting the inlet 131 and the tub inlet 23.

The insulating body 41 includes a ring-shaped first fixed body 411 fixed to the tub inlet 23, a ring-shaped second fixed body 412 fixed to the inlet 131, and the first fixed body. A cylindrical first extension body 413 extending from the body 411 toward the second fixing body 412, and a cylindrical shape extending from the second fixing body 412 toward the first fixing body 411 It may be provided to include a second extension body 414, and a connection body 416 connecting the first extension body and the second extension body.

The diameter R1 of the first extension body 413 is set larger than the diameter R2 of the second extension body 414, and the length of the first extension body 413 and the second extension body 414 The length of the second extension body 414 may be set such that the free end (one end located on the opposite side of the second fixed body) can be inserted into the first extension body 413. In order to prevent the vibration of the tub from being transmitted to the cabinet, the first extension body 413 and the second extension body 414 are preferably provided with an elastic body.

As shown in FIG. 4, the connecting body 416 is bent toward the second extension body 414 at the free end of the first extension body 413, so that the inflection surface of the first extension body 413 The first connection surface (P1) forming the (first inflection surface), the second extension body 414 is bent toward the first extension body 413 at the free end of the second extension body 414 It may be provided to include a second connection surface P2 forming a curved surface (a second curved surface), and a third connection surface P3 connecting the first connection surface and the second connection surface. In order to prevent the vibration of the tub from being transmitted to the cabinet, the first connection surface P1, the second connection surface P2, and the third connection surface P3 are preferably provided with an elastic body.

At least one of the first connection surface P1 and the second connection surface P2 may be provided to be parallel to the radial direction (X-axis direction) of the tub inlet 23, and FIG. A case in which both the first connection surface P1 and the second connection surface P2 are parallel to the plane formed by the tub inlet 23 is illustrated as an example.

When the first connection surface (P1) and the second connection surface (P2) are provided to be parallel to the diameter direction of the tub inlet 23, the distance between the inlet port 131 and the tub inlet 23 can be minimized. And, through this, the present invention can maximize the volume of the tub body 21.

It is assumed that the second connection surface P2 is provided in a convex shape toward the direction in which the tub inlet 23 is located. In this case, since the distance between the second connection surface P2 and the first fixed body 411 will be shortened, when the tub 2 vibrates, the second connection surface P2 and the first fixed body 411 ) Can rub against each other. To prevent such a problem, set the length of the first extension body 413 (the length of the first extension with respect to the Z-axis direction) to be longer to connect the second connection surface P2 and the first fixed body 411. It must be separated. However, setting the length of the first extension body 413 long is a design that moves the tub inlet 23 away from the inlet 131, and thus the volume of the tub is reduced (washing Capacity is reduced).

Meanwhile, it is assumed that the first connection surface P1 is provided in a convex shape toward the direction in which the inlet port 131 is located. In this case, since the distance between the first connection surface P1 and the front panel 13 is shortened, the first connection surface P1 may rub against the front panel 13 of the cabinet when the tub vibrates. have. In order to prevent damage to the insulating part 4 due to friction between the front panel 13 and the first connection surface P1, the first connection surface P1 is set to a longer length of the second extension body 414 And the front panel 13 must be separated from each other, and this design also has a problem that the volume of the tub is reduced.

Therefore, if at least one of the first connection surface (P1) and the second connection surface (P2) is provided in a plane parallel to the radial direction of the tub inlet 23, the tub fixed inside the cabinet having a limited volume There is an effect that can maximize the volume of.

However, the first connection surface (P1) and the second connection surface (P1) and the second connection surface of the insulating part (4) having the same thickness of the first extension body 413, the second extension body 414, and the connection body 416 If (P2) is provided, the vibration of the tub 2 may cause a problem of focusing on the second extension body 414.

Vibration of the tub generated by rotation of the drum 3, etc., passes through the first extension body 413 and the S-shaped connection body 416, and the second extension body 414 and the connection body 416 ), the second extension body 414 is fixed to the inlet 131 of the front panel 13, which vibrates less than the tub 2 (attenuates the vibration like a connecting body) Because there is no separate structure possible), it seems that the vibration of the tub is concentrated on the second extension body 414.

Whenever the tub 2 vibrates, if the vibration concentrates on the second extension body 414, a problem in which the second extension body 414 is torn may occur. However, by increasing the thickness of the second extension body 414, it is possible to prevent the vibration from being concentrated on the second extension body 414, but if the thickness of the second extension body 414 is increased, the second extension body 414 Another problem may occur in that vibration is concentrated on the contact (second connection surface, P2) between the extension body and the connection body.

According to the experiment, the thickness of the first extension body 413, the thickness of the first connection surface P1, the thickness of the second connection surface P2, and the thickness of the third connection surface P3 are If the same is set and the thickness of the second extension body 414 is set to increase from the second fixed body 412 toward the second connection surface P2 (t2>t1), the vibration of the tub is It has been confirmed that it is possible to effectively prevent concentration in a partial area of the insulating part 4.

However, the minimum thickness t1 of the second extension body 414 must be set to be larger than the thickness of the first extension body 413, the contact between the second extension body 414 and the second fixed body 412 This will prevent tearing or breaking problems.

Meanwhile, the length of the first connection surface P1, the length of the second connection surface P2, and the length of the third connection surface P3 may be set to be the same. This is to prevent the concentration of vibrations on connecting surfaces of different lengths.

Further, the inclination angle Q1 of the second extension body 414 with respect to the inlet port 131 and the inclination angle Q3 of the third connection surface P3 with respect to the first connection surface P1, the second connection surface It may be set to be the same as the inclination angle of the third connection surface).

FIG. 4 illustrates an example in which the inclination angles Q1 and Q2 are set to 110 degrees to 130 degrees. If the inclination angles (Q1, Q2) are less than 110 degrees, there may be a disadvantage that vibration is concentrated at the contact points (both ends of the third connection surface) of the connection surfaces, and when the inclination angles (Q1, Q2) are greater than 130 degrees, the connection This is because the degree of warpage of the body 416 is reduced, so that the ability to absorb vibration may decrease.

The insulating part 4 provided in the present invention may further include a rib 418 that increases the strength of the insulating body 41. The rib 418 may be provided as an elastic body having a bar shape (a shape that is longer than a width or height) protruding from the surface of the first extension body 413 and the surface of the connection body 416. The rib 418 may be provided with a plurality of elastic bodies disposed along the circumferential surface of the insulating body 41. Unlike shown in FIG. 4, the rib 418 may be provided only in the connection body 416.

Further, in the present invention, when water and clothing are introduced into the tub and the drum to cause sagging of the tub body 21 moving toward the base 11, the connecting body 416 and the second extension body ( By preventing 414 from contacting, a spacer for preventing the insulating part 4 from being damaged may be further included.

As shown in FIG. 5, the spacer 49 is located below the horizontal line H passing through the center of the tub inlet 23, and between the connecting body 416 and the second extension body 414 It may be provided to maintain the gap.

The spacer 49 provided in the present invention may be provided with an elastic body connecting the second connection surface P2, the third connection surface P3, and the circumferential surface of the second extension body 414. If the length of the spacer 49 is set too short, a problem may occur that does not prevent friction between the connection body 416 and the second extension body 414, and if the length of the spacer 49 is too long, the A problem of deteriorating the elasticity of the insulating body 41 may occur.

Accordingly, the length of the spacer 49 is set to be less than or equal to the distance (L1, the distance between the two connection surfaces in the longitudinal direction of the tub) between the first connection surface P1 and the second connection surface P2. This is desirable. The length of the spacer 49 is shorter than the distance (L1) between the first connection surface (P1) and the second connection surface (P2), and is set larger than 1/2 of the distance (L1) between the two connection surfaces It could be.

When sagging occurs in the tub body 21, the tub inlet 23 also moves toward the base 11, and the second extension body located below the horizontal line passing through the center of the tub inlet 23 ( 414 will move in the direction in which the connecting body 416 is located. In the present invention, since the spacer 49 is located between the second extension body 414 and the connection body 416, when the tub body vibrates, the second extension body 414 and the connection body 416 Can prevent rubbing against each other. In addition, the spacer 49 having the above-described structure has an effect of reinforcing the strength of the insulating body 41 together with the ribs 418.

In order to minimize such a problem, a connection passage may be further provided in the insulating part 4.

3, the connection passage 44 is a storage space 417 formed by the connection body 416 and the first extension body 413 for water discharged from the trap forming pipe 531. ) May be provided as a guide means. That is, the connection passage 44 may be provided as a groove provided on the second connection surface P2 to guide water moving along the surface of the guide 43 to the storage space 417.

The liquid moving along the surface of the guide 43 at a speed less than the reference speed (liquid moving at a speed less than the speed separated from the surface of the guide) is the connecting passage 44 located at the edge of the guide 43 Since it will move to the storage space 417 through the door 135, the present invention minimizes exposure of the water in the trap forming pipe 531 to the insulating body 41 when the door 135 is opened. .

On the other hand, the insulating body 41 is provided with a communication tube 47 connecting the storage space 417 to the tub body 21, the communication tube 47 is a horizontal line passing through the center of the tub inlet 23 It is located in the lower part of (H). Accordingly, the liquid supplied to the storage space 417 through the connection passage 44 will move to the tub 2 through the communication pipe 47.

The insulating body 41 located under the horizontal line H may further include an interference prevention unit preventing interference with the flow path body 71, and FIG. 5 shows the interference prevention unit on the base 11 It is shown as an example a case that is provided as a parallel area but located below the horizontal line (H). In this case, the communication pipe 47 may be provided on the horizontal portion.

The communication pipe 47 may be provided to be located on a vertical line (V) passing through the center of the tub inlet, or may be provided at a position deviating from the vertical line (V). 5 shows a case where the communication pipe 47 is provided at a position separated from the vertical line V, which is a result of the supply pipe 72 of the injection unit 7 described above being disposed on the vertical line V .

Since the present invention can be implemented in various forms, the scope of the right is not limited to the above-described embodiment. Therefore, if the modified embodiment includes the components of the claims of the present invention, it should be regarded as belonging to the scope of the present invention.
