At this time, two pairs of blocking walls 101 are formed in the connection part 100.

In more detail, as shown in FIG. 4 or FIG. 5, the two pairs of blocking walls 101 may include a pair of front side blocking walls 101a protruding from each other and the pair of front sides. It is composed of a pair of rear side blocking walls 101b spaced rearward from the blocking wall 101a and facing each other, and the pair of front side blocking walls 101a and the pair of rear side blocking walls ( 101b) are staggered from each other.

Here, ribs 103 supporting the blocking wall 101 are formed at the junction between the blocking wall 101 and the connection part 100.

In addition, a handle 113 is formed on the outside of the fixing part 110 to hold the ventilation pipes 100 and 110.

Of course, two pairs of barrier walls 101 are formed, but three or less or five or more barrier walls 101 may be formed.

In addition, the blocking wall 101 is formed in the ventilation pipes 100 and 110, but may be formed in the ventilation bellows 82 or the ventilation hole 65.

As shown in FIGS. 4 and 5, the noise generated in the tub of the washing machine is reflected by the reflection path NP by the blocking wall 101 and is prevented from traveling outside the washing machine.                     

The result of experimenting the degree of blocking of the noise by the blocking wall 101 is as follows.

As a result of measuring the noise level from the rear of the cabinet of the washing machine during the washing process of the washing machine, the noise generated in the washing process of the washing machine applying the ventilation pipe according to the prior art was measured as 60 (dB), but the barrier wall according to the present invention. The noise generated in the washing process of the washing machine to which the ventilated pipe was formed was measured as 57.5 (dB) to obtain a 2.5 (dB) reduction effect. This means that the noise reduction effect of about 44% is obtained by the formation of the two pairs of blocking walls 101. (, I is the sound intensity, is the reference sound intensity,)

The soundproof means according to the second embodiment of the present invention is formed so that the blocking wall 131 protrudes from the inner wall of the connection portion 130 of the ventilation pipe so that the inner flow path of the ventilation pipe 130, 140 is zigzag.

In particular, the blocking wall 131 is formed to be inclined toward the inside of the cabinet (not shown) toward the center of the ventilation pipes 130 and 140.

6 is a partially cutaway perspective view of the ventilation pipe according to the second embodiment of the present invention, and FIG. 7 is a side view of the ventilation pipe according to the second embodiment of the present invention.

Here, the connecting portion 130 is formed in a cylindrical shape with both sides open, the fixing portion 140 is formed in the outlet hole (W2) to ventilate the tub (not shown) and the outside of the washing machine.

Thus, the air in the tub (not shown) is ventilated with the outside of the washing machine by the inlet hole (I2) and the outlet hole (W2) opened in the connecting portion 130.

Here, fixing means 141, 142 for fixing the fixing part 140 to the back of the cabinet is formed in the fixing part 140.

The fixing means 141 and 142 are provided on a fixing member I 141 having a protrusion 141a formed to correspond to the hole (not shown) so as to fit into a hole (not shown) formed in the rear of the cabinet, and the rear of the cabinet. It consists of a fixing member II (142) formed with a fitting member (142a) to be fitted to fit in the formed fitting hole (not shown).

At this time, two blocking walls 131 are formed in the connection part 130.

In more detail, as shown in FIG. 7, the blocking wall 131 is formed to protrude so that the internal flow path NP2 of the ventilation pipes 130 and 140 is zigzag, and the ventilation pipe 130 is It is formed to be inclined toward the inside of the cabinet toward the center of the 140.

Here, ribs 133 supporting the blocking wall 131 are formed at the junction between the blocking wall 131 and the connection part 130.

Noise generated in the tub (not shown) is exhausted by reflecting the reflection path (NP2a) by the blocking wall 131 or by causing an interference phenomenon while traveling in a zigzag path (NP2b) between the blocking wall (131) .

As a result, noise generated in the tub (not shown) is prevented from leaking outside the cabinet (not shown).

Of course, two blocking walls 131 may be formed, but one or three or more blocking walls 131 may be formed, and even if the blocking walls 131 are not inclined, noise may be reduced by the interference phenomenon. .

Here, the blocking wall 131 is not formed in the ventilation pipe, but may be installed in the ventilation bellows or the ventilation hole.

In the ventilation pipe according to the third embodiment of the present invention, a chamber part is formed.

At this time, the chamber portion (R) in which the inlet hole (S) is formed is formed in the connection portion (160).

In more detail, a chamber portion R is formed in the connection portion 160, and a gap d is formed so that noise introduced into the inlet portion I3 can flow out to the outlet portion W3. do.

Here, the inlet hole S is formed in the chamber part R, and the inlet hole S of each chamber part R is formed to face each other. The gap d is a space spaced apart from the chamber portions R, and the inflow hole S is formed in the gap d.

Of course, two chamber portions R may be formed, but one or three or more chamber portions R may be formed, and the inflow hole S may be formed in the chamber portion R to face the noise propagation direction.

The noise generated by the tub is reflected by the reflection path NP3a by the blocking wall 161, or enters the chamber part R through the inflow hole S, thereby interfering with other noise, and extinguishes the noise. This is prevented from going out of the washing machine.                     

Here, the chamber part R is not formed in the ventilation pipe, but may be installed in the ventilation bellows or the ventilation hole.

Washing machine according to the present invention comprises a ventilator installed to communicate the inside of the tub with the outside of the cabinet, the soundproof means for shielding the noise is formed inside the ventilator, the noise generated in the tub is soundproof It is blocked by the means to reduce the noise in the washing, rinsing, dehydration process, and also the moisture discharged from the tub is discharged to the outside of the washing machine through the ventilator to damage the outer wall of the washing machine and the moisture is the ventilator It has the effect of preventing damage to external consumer property.
