Further, the elongated hole 36e is located closer to the outer diameter side of the ring portion 36b.

Further, the fixing member 36 is formed with a fixing portion 36d1 extending horizontally inward in the radial direction at the outer diameter side hanging lower portion 36d. The fixed portion 36d1 is integrally formed with the wall surface of the outer diameter side hanging portion 36d. Further, the fixing portion 36d1 is formed at a position where it overlaps with the elongated hole 36e in the axial direction (vertical direction).

Further, the fixed portion 36d1 is formed with a tapered surface 36d2 that descends in a direction away from the elongated hole 36e on the surface on the elongated hole 36e side. The tapered surface 36d2 is formed at the end of the fixed portion 36d1.

As described above, in the fixing member 36, the fixing portion 36d1 is located on one side of the elongated hole 36e in the circumferential direction, and the hole penetrating in the axial direction (vertical direction) is located on the other side in the circumferential direction.

As shown in FIG. 7, the inner diameter side hanging portion 36c is formed in a cylindrical shape, and the length from the upper end to the lower end is formed to be the same at any position in the circumferential direction. The outer diameter side hanging portion 36d is formed in a substantially cylindrical shape. Further, the length from the upper end (ring portion 36b side) to the lower end is formed so that the portion corresponding to the elongated hole 36e is longer than the portion without the elongated hole 36e.

Further, the fixed portion 36d1 is formed with a thickness in the axial direction (vertical direction) to ensure the strength. Further, a gap S is formed between the fixed portion 36d1 and the ring portion 36b into which the holding portion 31d2 formed on the tank cover 31 is inserted while sliding.

FIG. 8 is a perspective view showing a state in which the fixing member is attached to the blower bellows.
As shown in FIG. 8, when the blower bellows 29b is attached to the tank cover 31, the fixing member 36 is first attached to the blower bellows 29b. Since the blower bellows 29b is made of an elastic material such as rubber, the blower bellows 29b can be attached by deforming the blower bellows 29b so as to pass through the hole (inner diameter side hanging portion 36c) of the fixing member 36. At this time, the fixing member 36 is inserted until it is located at the cylindrical portion 29b3 (see FIG. 4) of the blower bellows 29b. With the fixing member 36 attached to the blast bellows 29b, the blast bellows 29b and the fixing member 36 are lowered from above the cylindrical body 31c of the tank cover 31.

FIG. 9 is a plan view showing a state before rotation of the fixing member.
As shown in FIG. 9, the fixing member 36 is located at a position where the holding portion 31d2 of the fixing rib 31d overlaps with the elongated hole 36e in the vertical direction, and the fixing rib 31d and the fixing portion 36d1 do not overlap with each other in the vertical direction. The fixing member 36 is lowered toward the tank cover 31 so as to be. The holding portion 31d2 is set to a length so that the entire holding portion 31d2 can be visually recognized from the elongated hole 36e.

FIG. 10 is a plan view showing a state in which the fixing member is rotating.
As shown in FIG. 10, when the fixing member 36, which is a movable part, is rotated in the W direction (clockwise direction), that is, when the fixing portion 36d1 is rotated in a direction approaching the holding portion 31d2, the fixing portion 36d1 is a non-movable part. It goes under the holding portion 31d2 of a certain fixed rib 31d, and the fixed portion 36d1 and the holding portion 31d2 overlap each other in the vertical direction (vertical direction). At this time, the fixing member 36 rotates while the lower surface of the holding portion 31d2 and the upper surface of the fixing portion 36d1 slide. Note that FIG. 10 shows a state in which the fixing member 36 is rotated halfway in the W direction, and shows a state in which a part of the fixing portion 36d1 and a part of the holding portion 31d2 are overlapped in the vertical direction.

Further, at this time, a tapered surface 36d2 (see FIG. 5) is formed in the fixed portion 36d1, and a gap S at the entrance through which the fixed portion 36d1 penetrates is widely formed. This makes it easier to insert the fixing portion 36d1 into the gap S when the fixing member 36 is rotated.

FIG. 11 is a plan view showing a state after the rotation of the fixing member is completed.
As shown in FIG. 11, when the fixing member 36 is further rotated in the W direction from the state shown in FIG. 10, the entire holding portion 31d2 overlaps with the fixing portion 36d1 in the vertical direction. In FIG. 11, the fixing portion 36d1 is located on the lower side (the back side in the vertical direction of the paper surface) of the holding portion 31d1. The fixing member 36 is formed with protrusions (not shown) on which a force for urging the fixing member 36 downward in the vertical direction acts.

FIG. 12 is a cross-sectional view of the fixing member after the rotation is completed. The cross-sectional view of FIG. 12 is shown schematically.
As shown in FIG. 12, the upper surface of the fixing portion 36d1 of the fixing member 36 is in contact with the lower surface of the holding portion 31d2 of the fixing rib 31d. As a result, the fixing member 36 does not come off in the direction away from the tank cover 31, and as a result, the blower bellows 29b does not come off from the tank cover 31.

Further, in the fixing member 36, an inner diameter side hanging lower portion 36c is formed, and the brim portion 29b4 of the blow bellows 29b is sandwiched between the tip end (lower end) of the inner diameter side hanging lower portion 36c and the mounting surface 31b1 of the tank cover 31. As a result, the blower bellows 29b is prevented from coming off the tank cover 31.

Further, when the blast bellows 29b is attached to the cylindrical body 31c, the cylindrical portion 29b3 of the blast bellows 29b is elastically deformed and attached while being expanded, so that the inner peripheral surface of the cylindrical portion 29b3 is the outer peripheral surface of the cylindrical body 31c. It will be in close contact with. This makes it possible to prevent air (warm air) from leaking from between the cylindrical body 31c and the cylindrical portion 29b3.

As described above, in the present embodiment, the first fixing means for fixing the blower bellows 29b by the fixing portion 36d1 of the fixing member 36 and the holding portion 31d2 of the fixing rib 31d, the inner diameter side hanging portion 36c of the fixing member 36, and the tank. By providing a second fixing means for fixing the blower bellows 29b by the mounting surface 31b1 of the cover 31, the blower bellows 29b can be firmly fixed to the tank cover 31.

FIG. 13 is a perspective view showing a state before attaching the holding member to the tank cover. FIG. 14 is a plan view showing a state after the holding member is attached to the tank cover.
By the way, in the washer / dryer 100, vibration is generated during operation, and the vibration may cause the fixing member 36 to rotate in the circumferential direction (the direction opposite to the W direction in FIG. 6) and loosen. Therefore, in the present embodiment, the holding member (stopper) 37 is used to prevent the fixing member 36 from loosening due to vibration.

As shown in FIG. 13, the holding member 37 is used by being inserted into the elongated hole 36e, and has a base portion 37a, an insertion portion 37b, and a locking claw portion 37c. The base portion 37a is formed along the arcuate shape of the elongated hole 36e. The insertion portion 37b extends vertically downward from one end in the circumferential direction (longitudinal direction) of the base portion 37a. The locking claw portion 37c extends in the same direction as the insertion portion 37b from the other end in the circumferential direction (longitudinal direction) of the base portion 37a. Further, the locking claw portion 37c has a claw protruding outward in the circumferential direction. The holding member 37 configured in this way is attached to one of the three elongated holes 36e formed in the fixing member 36.

As shown in FIG. 14, substantially half of the elongated hole 36e in the circumferential direction penetrates in the vertical direction (axial direction). In such a state, in the holding member 37, the insertion portion 37b (see FIG. 13) is inserted into the position 36e1 on the side of the fixing portion 36d1 (holding portion 31d2), and the locking claw portion 37c (see FIG. 13) is inserted into the fixing portion 36d1. It is inserted at the position 36e2 on the opposite side of the above. The locking claw portion 37c (see FIG. 13) is inserted into the elongated hole 36e while bending and deforming. As a result, the insertion portion 37b (see FIG. 13) is in contact with the end face of the fixing portion 36d1. The locking claw portion 37c (see FIG. 13) is locked to the edge portion of the circumferential end of the elongated hole 36e. As a result, the holding member 37 is prevented from coming out of the elongated hole 36e.

Since the length of the holding member 37 in the circumferential direction is sized to fit into the elongated hole 36e, after the fixing member 36 mounts the holding member 37, the fixing member 36 is in the direction opposite to the W direction (see FIG. 6). Does not rotate to. That is, since the fixing member 36 is not loosened and the engagement state between the fixing portion 36d1 of the fixing member 36 and the holding portion 31d2 of the fixing rib 31d is not released, the blower bellows 29b does not come off from the tank cover 31. ..

In the washing / drying machine 100 having such a configuration, in the drying process of the washing / drying machine 100, it is necessary to increase the rotation speed (rotational speed) of the blower fan 19 to increase the air volume in order to improve the drying finish. However, when the air volume is increased, the internal pressure also rises at the same time. May come off from the tank cover 31.

Here, FIG. 15 shows a conventional method for fixing the blast bellows. A wire clip 200 is used for fixing the conventional bellows. As an assembly method, as shown in FIG. 15, after the wire clip 200 is incorporated in the end of the blower bellows 300, it is attached to the warm air intake port 410 of the tank cover 400. A tightening force F by the wire clip 200 acts on the blower bellows 300, and the maximum static friction force is N = μF, where μ is the static friction coefficient between the tank cover 400 and the blower bellows 300. When the pulling force P due to the elongation of the blower bellows 300 exceeds the maximum static friction force N (P> N), the tightening effect of the wire clip 200 is lost, and slippage occurs at the connection interface between the blower bellows 300 and the tank cover 400. Warm air leaks from the interface, reducing the spraying force to dry the garment. As a countermeasure, the cross-sectional area of the wire clip 200 can be increased or the material can be changed to increase the tightening force F, but this requires the power of an operator when attaching the blower bellows 300 to the tank cover 400. Or you have to use a special tool, which makes workability worse.

Therefore, in the present embodiment, the configuration shown below is used. That is, the washer / dryer 100 blows warm air to the washing / dehydrating tub 9, the outer tub 10 containing the washing / dehydrating tub 9, the tub cover 31 covering the opening 10a of the outer tub 10, and the washing / dehydrating tub 9. It has a blower fan 19 for blowing air, a blower bellows 29b for connecting the blower fan 19 and a tank cover 31, and a fixing member 36 for fixing the tank cover 31 and the blower bellows 29b. The fixing member 36 has a fixing portion 36d1 fixed to the tank cover 31 in a state of being attached to the blower bellows 29b (see FIG. 12). According to this, since the fixing portion 36d1 is fixed to the tank cover 31, it is possible to suppress the concern that the blower bellows 29b will come off from the tank cover 31. As a result, the concern about air leakage can be reduced, and a washer / dryer 100 with a good drying finish can be realized.

Further, in the present embodiment, the blower bellows 29b is fixed by the fixing member 36 and the tank cover 31 (see FIG. 7). According to this, when used in combination with the fixing by the fixing portion 36d1, the concern that the blast bellows 29b may come off can be further suppressed.

Further, in the present embodiment, the tank cover 31 has a holding portion 31d2 to be fastened to the fixing portion 36d1 (see FIG. 12). According to this, the fixing portion 36d1 and the holding portion 31d2 of the fixing rib 31d can be stably fixed to each other.

Further, in the present embodiment, the fixing ribs 31d have a plurality of holding portions 31d2 (see FIG. 4). According to this, it is possible to further prevent the blower bellows 29b from coming off the tank cover 31.

Further, in the present embodiment, the fixing member 36 is made of resin. According to this, the fixing member 36 can be made low cost and lightweight, and the worker can easily attach the blower bellows 29b.

Further, in the present embodiment, there is a holding member that holds a state in which the fixing portion 36d1 and the holding portion 31d2 are fastened (see FIGS. 8 and 9). According to this, it is possible to prevent the fixing member 36 from loosening due to vibration during operation of the washer / dryer 100.

Further, in the present embodiment, the fixing member 36 is fixed to the holding portion 31d2 by rotating. The blower bellows 29b can be easily fixed as compared with the conventional fixing with a wire clip.

Further, the blower bellows 29b of the present embodiment has a bellows portion 29b1 that expands and contracts, a cylindrical portion 29b3 having a diameter smaller than that of the bellows portion 29b1 to which the fixing member 36 is attached, and a fixing member 36 and a tank cover at the end of the cylindrical portion 29b3. It has a brim portion 29b4 fixed to and from 31 (see FIG. 7). According to this, since the brim portion 29b4 can be sandwiched between the fixing member 36 and the tank cover 31, the blower bellows 29b is less likely to come off from the tank cover 31.

Further, the fixing member 36 of the present embodiment is a fixing member for blowing bellows that fixes the blowing bellows 29b to the tank cover 31 that covers the washing / dehydrating tank 9, and is attached to the blowing bellows 29b. A ring portion 36b arranged around the ring portion 36b, a fixing portion 36d1 provided on the outer diameter side of the ring portion 36b and fixed to the tank cover 31, and a blast bellows 29b provided on the inner diameter side of the ring portion 36b to cover the tank cover. It has an inner diameter side hanging portion 36c that is sandwiched and fixed by 31 (see FIG. 7). According to this, it is possible to realize the fixing between the holding portion 31d2 of the tank cover 31 and the fixing between the brim portion 29b4 of the blower bellows 29b and the tank cover 31 by one fixing member 36. It is possible to eliminate the concern that the blower bellows 29b will come off from the tank cover 31.

The present invention is not limited to the above-described embodiment. For example, in the present embodiment, the heater 20 has been described as a heat source, but the same effect can be obtained even if the heat source is a heat pump.

Further, in the present embodiment, the case where the fixing member 36 is rotated and attached to the fixing rib 31d has been described, but the fixing member 36 may be formed by pressing and fitting the fixing member 36 against the fixing rib 31d.
