Further, an air tube 28 is connected to the air trap 26 so as to communicate with a water level sensor (not shown).

Further, a second drain port 29 is formed near the first drain port 25 at the bottom of the outer tub 12.
A drain valve 30 is commonly connected to the second drain port 29 and the first drain port 25. Therefore, the drain valve 30 has the first connection port 31 connected to the first drain port 25 and the second connection port 32 connected to the second drain port 29, and the first drain port 30 has the first drain port. The water in the inner tub 14 flowing from the port 25 is discharged from the outlet 33 by opening a valve body (not shown), and the water in the outer tub 12 flowing from the second connection port 32 is irrespective of the opening and closing of the valve body. The air is discharged from the outlet 33 through the peripheral portion.

A drain hose 34 is connected to the outlet 33 of the drain valve 30. The drain hose 34 comprises an inner drain hose 35 and an outer drain hose 36 shown in FIG.
3 is connected to a connecting portion 37 of the in-machine drainage hose 35, and an adhesive 38 is applied to the inner peripheral surface of the connecting portion 37 as shown in FIG. Part 37
Is fitted to the outlet portion 33 of the drain valve 30, and the structure is fastened by a fastening ring 39 from above. In addition, connection part 3
In FIG. 7, bulging portions 40, 41 functioning as an adhesive reservoir and straight portions 42, 43 are alternately formed, and the upper straight portion 42 is fastened by a fastening ring 39.

Further, the inboard drainage hose 35 has a straight portion 44 formed at a position separated by a predetermined distance from the connection portion 37. In addition, as shown in FIG. And a connection part 45 for connection with the other parts, and the rest except for these are formed in a bellows shape having flexibility and elasticity.

The connecting portion 3 of the in-machine drainage hose 35
A holding member 46 is attached to a portion near 7. As shown in FIG. 4, the holding member 46 is formed in a shape of an elbow and is divided into two parts, and is integrally connected by a self-hinge part 47. By attaching to the portion near the connecting portion 37, the portion near the connecting portion 37 of the inboard drainage hose 35 is contracted on the upper side and extended on the lower side, thereby forming an elbow shape (inverted L-shape in the state of FIG. 1). Bent. Also, the holding member 46 combined into one is engaged with the two coupling claws 48 formed on one side thereof with the two coupling holes 49 formed on the other side, respectively, so that both sides are coupled to each other. The portion near the connection portion 37 of the inner drainage hose 35 is held in an elbow-like bent state.

Here, the holding member 46 has mouth portions 50 at both ends.
51, and one of the mouths 50 has an inner drainage hose 3
5, covering the lower straight portion 43 in the connection portion 37,
In the other mouth portion 51, a straight portion 4 on the side opposite to the drainage valve 30 in the portion near the connection portion 37 of the inboard drainage hose 35.
4 are not fixed, and are thereby provided rotatably in the circumferential direction of the in-machine drainage hose 35.

In addition, in this case, in particular, the inner diameter D of the one mouth portion 50 is set to be larger than the outer diameter d of the straight portion 43 of the inside drain hose 35 connected to the outlet portion 33 of the drain valve 30. (D> d), and the inner diameter E of the other mouth portion 51 is set to be larger than or equal to the outer diameter e of the straight portion 44 (E ≧ e).

Further, ribs 52 and 53 are formed in the inboard drainage hose 35 above and below a portion on the tip side of the straight portion 44 to prevent the portion from being bent downward. 52 and 53 also function as identification portions for confirming the twist position of the in-machine drainage hose 35 with respect to the holding member 46, as described later.

In addition, as shown in FIG.
At the bottom of the left and right side walls, drainage outlets 54,
55, of which the hose outlet 5 on the right side is formed.
5, the distal end portion (connecting portion 45) of the inside drain hose 35 faces the outside drain hose 36 to the inside drain hose 35 at the hose outlet 55.

By the way, in the case of the structure as described above,
The water discharged through the drain valve 30 is discharged to the outside of the machine through the inside drain hose 35 and the outside drain hose 36 in a state where the outside drain hose 36 of the drain hose 34 is tilted. In the case of, it is discharged to the right.

On the other hand, if the holding member 46 is rotated with the connecting portion 37 of the in-machine drain hose 35 connected to the outlet portion 33 of the drain valve 30, the holding member 46 bends into an elbow shape. The portion near the connecting portion 37 of the inboard drainage hose 35 transfers the contracted portion and the extended portion along the elbow in the circumferential direction of the inboard drainage hose 35, thereby connecting the inboard drainage hose 35. The bending direction of the portion near the portion 37 changes, and the direction is changed.

FIG. 5 shows the state at this time. When the holding member 46 is rotated by an angle of 180 degrees, the drainage hose 35 inside the machine is also turned by 180 degrees. At this time, the inside drain hose 35 is connected to the upper and lower ribs 52 and 53.
As can be clearly seen from the exchange of the angle, the angle is also rotated by 180 degrees in the circumferential direction.

FIG. 6 shows the inboard drainage hose 35 whose direction has been changed as described above by a two-dot chain line. In this state, the hose outlet 55 on the left side is replaced with the hose outlet 55 on the left side. The distal end portion (connecting portion 45) of the inboard drainage hose 35 faces the outside drainage hose 36 connected to the inboard drainage hose 35 at the left hose outlet 54 from the right hose outlet 55. Therefore, in this case, the water discharged through the drain valve 30 is supplied to the inside drain hose 35 while the outside drain hose 36 is tilted.
Then, the water is discharged to the left through the outside drain hose 36 in order.

As described above, according to the present configuration, the holding member 4
6 can be rotated to change the direction of the inboard drainage hose 35, and if it is not necessary to remove the inboard drainage hose 35, the joints, etc. from the drainage valve 30 one by one and reconnect as in the conventional case. The workability can be improved. In addition, since the inside drain hose 35 is not once removed and then reconnected, the connection failure of the connection of the inside drain hose 35 to the drain valve 30 due to reconnection is prevented. it can.

In addition, especially in the above configuration,
The holding member 46 is connected to one of the mouth portions 50 by the in-machine drainage hose 35.
Of the inner side drain hose 35 in a state where the inner diameter D of the mouth part 50 is connected to the outlet part 33 of the drain valve 30. Since the outer diameter d is set to be larger than the outer diameter d, when the holding member 46 is rotated, the mouth portion 50 does not receive the frictional resistance force due to the straight portion 43, and the holding member 46 can be rotated more smoothly. The direction of the drain hose 35 can be more easily changed.

The holding member 46 covers the straight portion 44 on the other side of the drainage hose 35 on the side opposite to the drainage valve 30 in the vicinity of the connection portion 37 of the inside drainage hose 35 at the other mouth portion 51.
Since the inner diameter E of the first member is larger than or equal to the outer diameter e of the straight portion 44, when the holding member 46 is rotated, the mouth portion 51 does not receive the frictional resistance force due to the straight portion 44, so that also. Since the holding member 46 can be smoothly rotated, the direction of the in-machine drainage hose 35 can be further easily changed.

In this case, the inner diameter E of the mouth portion 51 may be equal to the outer diameter e of the straight portion 44 because the straight portion 44 has an inside such as the outlet portion 33 of the drain valve 30. And the inward deformation (deflection) is free, and the opening 5
This is because, even if 1 is in contact, it does not give a frictional resistance force that hinders its rotation.

Further, when the direction of the inside drain hose 35 is changed by the rotation of the holding member 46, the inside drain hose 3
Numeral 5 also rotates in the circumferential direction.
If the angle can be changed by 0 degree, it is rotated 180 degrees in the circumferential direction.
At this time, in the above configuration, the inboard drainage hose 35 is used.
Ribs 5 formed above and below a portion on the distal end side of the straight portion 44
Since 2 and 53 are interchanged, if they match the upper and lower joints (self-hinge portion 47) of the holding member 46, it is confirmed that the inboard drainage hose 35 is not twisted,
If not, the inside drain hose 35 may be rotated in the circumferential direction until it does. Thus, the inboard drainage hose 35 can be used without being twisted, so that the connection with the outboard drainage hose 36 can be performed correctly.

Moreover, in this case, the ribs 52 and 53 are originally formed on the in-machine drainage hose 35 so as to prevent the portion on the tip side from the straight portion 44 from being bent downward. As described above, since it can function as an identification unit for confirming the twist position of the in-machine drainage hose 35, it is not necessary to separately provide a dedicated identification unit.

7 and 8 show a second embodiment of the present invention. In the inside drain hose 35, a convex portion 61 is formed as an identification portion instead of the ribs 52 and 53 described above. The corresponding notch 62 is inserted into the opening 5 of the holding member 46.
One formed at one edge is shown.

In this case, it is confirmed that the inboard drainage hose 35 is not twisted because the convex portion 61 matches the notch portion 62, and if not, the inboard drainage hose 35 is rotated until it matches. Rotate in the direction. In this case, when the inboard drainage hose 35 rotates in the circumferential direction, slopes 61a are formed on the upper and lower surfaces of the protrusion 61, respectively, so that the protrusion 61 does not catch on the notch 62. .

FIG. 9 shows a third embodiment of the present invention.
A concave portion 63 is formed at the edge of the mouth portion 51 of the holding member 46 in place of the cutout portion 62, and the concave portion 63 is formed in the same manner as the above-mentioned convex portion 61 (has a large length)
Are shown in such a manner that the convex portions 64 of FIG.
Even in this case, the same operation and effect as in the second embodiment can be obtained.

[0036]

The present invention is as described above.
The following effects are obtained. According to the first aspect of the present invention, since the direction of the drain hose can be changed only by rotating the holding member, the workability of changing the direction of the drain hose can be improved, and the connection of the drain hose to the drain valve can be improved. It is possible to prevent the occurrence of connection failure due to reconnection of the portion.

According to the washing machine of the second aspect, since the holding member can be rotated more smoothly, the direction of the drain hose can be more easily changed. According to the washing machine of claim 3,
Since the holding member can be rotated more smoothly, the direction of the drain hose can be more easily changed.

According to the washing machine of the fourth aspect, the drain hose can be easily and clearly identified for use without twisting. According to the washing machine of claim 5, while the drainage hose can be easily and clearly identified for use without twisting,
