Between the washing machine main body 6 and the outer tub 3, a safety device 8 is mounted that operates when abnormal vibration due to clothing imbalance in the washing / dehydrating tub 1 occurs. As shown in FIG. 9, elastic bodies 9 a and 9 b facing a part of the outer peripheral surface of the outer tub 3 are attached.
[0005]
In general, in such a washing / dehydrating washing machine, when the washing process is finished and the washing / dehydrating tub 1 is rotated, the outer tub 3 vibrates horizontally or vertically due to clothing imbalance. In some cases, abnormal vibrations may occur that cause the washing machine body 6 to vibrate or move greatly. At this time, the elastic bodies 9a and 9b are attached to the washing machine body 6, the outer tub 3 and the elastic bodies 9a and 9b come into contact with each other, and the outer tub 3 hits the safety device 8, whereby the safety device 8 is activated and the clothes are unbalanced. Is set so that the dehydration process starts again.
[0006]
[Problems to be solved by the invention]
In such a conventional configuration, when washing, dehydrating, and taking out clothes, the outer tub 3 moves to contact the elastic bodies 9a and 9b, and the elastic bodies 9a and 9b are, as shown in FIG. Since the surface is smooth, abnormal noise is generated due to friction, or abnormal vibration due to clothing imbalance occurs depending on the weight distribution due to the arrangement of the motor 5 and other mechanical parts and electrical parts under the outer tub 3 In this case, due to the vibration of the outer tub 3 due to the rotation direction of the washing machine / dehydrating tub 1, the elastic bodies 9a and 9b do not generate a force to vibrate the outer tub 3 to the safety device 8, and the safety device 8 does not operate reliably. In the dehydration process, there is a problem that abnormal noise is generated from the washing machine body 6 or the washing machine body 6 moves.
[0007]
The present invention solves the above-described conventional problems, and does not generate abnormal noise even when the outer tub and the elastic body come into contact, and ensures that the safety device works against abnormal vibration of the outer tub. It is an object.
[0008]
[Means for Solving the Problems]
The present invention, in order to achieve the above object, the washing and dewatering tank elastically supported from the four corners of the washing machine body by the four suspension the outer tank to the envelope, one of the four suspension vibration of the outer tub It detects with the safety device provided in the vicinity of the 1st suspension which comprises . An elastic body having a smooth surface facing a part of the outer peripheral surface of the outer tub is sandwiched between the second suspension located diagonally to the first suspension at a position substantially diagonal to the safety device of the washing machine body. secured on both inner side surfaces of the washing machine main body, the outer peripheral surface of the outer tub, to the contact surface outer tub you contact with smooth surface of the elastic body when swung, substantially longitudinal rib of the plurality of Alternatively, a plurality of substantially lattice-like ribs are provided.
[0009]
As a result, even when the outer tub comes into contact with the elastic body during washing, dehydration, and taking out clothes, a plurality of substantially vertically long ribs or a plurality of substantially lattice-like ribs and a smooth surface of the elastic body Can prevent the occurrence of abnormal noise due to friction, and the smooth surface of the elastic body is in contact with a plurality of substantially vertically long ribs or a plurality of substantially lattice-like ribs when dehydration is started. time, it is the force that restricts the rotation movement of the outer tub by rotation of the washing and dewatering tank in the direction of movement of the safety device occurs, to ensure that the safety device works.

[0011]
【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0012]
Example 1
As shown in FIG. 2, the washing / dehydrating tub 10 encloses an outer tub 11 and receives water during washing and dehydration by the outer tub 11. A speed reducer 13 connected to the motor 12 by a belt is fixed to the lower portion of the outer tub 11. The drive shaft of the speed reducer 13 has a double structure. The washing / dehydrating tub 10 is fixed to the outer shaft by a flange 14 attached to the lower part of the washing / dehydrating tub 10, and the washing / dehydrating tub 10 is fixed to the inner shaft. A stirring blade 15 provided at the inner bottom of the water tank 10 is fixed.
[0013]
Further, the outer tub 11 is supported by a suspension 17 from the four corners of the washing machine body 16 in a vibration-proof manner. A fluid balancer 10 a enclosing a liquid is attached to the upper part of the side surface of the washing and dewatering tub 10. A safety device 18 is attached between the washing machine main body 16 and the outer tub 11, and the outer periphery of the outer tub 11 is positioned on the washing machine main body 16 at a position substantially diagonal to the safety device 18, as shown in FIG. 1. Elastic bodies 19a and 19b facing part of the surface are attached.
[0014]
When the outer tub 11 is swung, as shown in FIGS. 3 and 4, substantially vertically long ribs (protrusions not in surface contact) 20 are provided on the contact surface 11 a of the outer tub 11 that contacts the elastic bodies 19 a and 19 b. A plurality are provided at predetermined intervals.
[0015]
Explaining the operation in the above configuration, the rib 20 becomes a resistance against the elastic bodies 19a and 19b, the area in close contact with the outer tub 11 is reduced, and the outer tub 11 is elastic when washing, dehydrating and taking out clothes. Even if it contacts the bodies 19a, 19b, the area of close contact is small, so no abnormal noise is generated.
[0016]
Further, as shown in FIG. 5, when the outer tub 11 vibrates at the time of dehydration, the rib 20 becomes a resistance against the elastic bodies 19 a and 19 b, so that the outer tub 11 is washed and detached with respect to the motor 12. In contrast to the vibration of D1 in the rotation direction of the water tank 10, a force F1 that restricts the movement of the outer tank 11 is generated in the direction of the safety device 18, and the safety device 11 can be surely operated.
[0017]

As shown in FIG. 6, 21 (protrusion not in surface contact with) the substantially lattice-shaped rib, when the outer tub 11 is swung, the contact surface 11a of the outer tub 11 to contact the elastic bodies 19a, and 19b, predetermined A plurality are provided at intervals. Other configurations are the same as those of the first embodiment.
[0018]
Explaining the operation in the above configuration, the rib 21 is more resistant to the elastic bodies 19a, 19b than the first embodiment, the area in close contact with the outer tub 11 is reduced, and washing, dehydration and clothing are reduced. Even when the outer tub 11 comes into contact with the elastic bodies 19a and 19b when taking out, an abnormal sound is prevented from being generated because the contact area is small.
[0019]
Further, as shown in FIG. 5, when the outer tub 11 vibrates at the time of dehydration activation, the rib 21 becomes a resistance against the elastic bodies 19 a and 19 b, so that the outer tub 11 is washed and detached with respect to the motor 12. In contrast to the vibration of D1 in the rotation direction of the water tank 10, a force F1 that restricts the movement of the outer tank 11 is generated in the direction of the safety device 18, and the safety device 11 can be surely operated.
[0020]
In the above embodiment, the protrusions that do not come into surface contact are formed by the substantially vertically long ribs 20 and the substantially lattice-like ribs 21, but they may be formed by polygonal ribs, aggregates of protrusions, or the like. The same effect can be obtained.
