Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to setting of a lead wire provided in a lower portion of an outer tub in a fully automatic washing machine.

[0002]

2. Description of the Related Art An outer tub 32 provided in an outer frame 31 is attached to a hanging rod 34.
A motor 35, a clutch mechanism 36, etc. are arranged at the bottom of the outer tub 32 as shown in FIG. The control of these electric appliances is performed by using the top cover 37 for the electric appliances.
The lead wire 39 must be provided between the outer frame 31 and the outer tub 32 in order to perform the control-coupled operation by the substrate 38 provided in the. Conventionally, this arrangement is such that the lead wire 40 from the substrate 38 is attached to the outer frame 31 at a plurality of positions with fixing members 44, connectors, etc., and the lower stage thereof is connected to the outer tub 32 and arranged on the electric appliance as shown in FIG. Was there. As a result, the lead wires are constantly shaken with the shake of the lower portion of the outer tub 32, so that the lead wires are often broken.

[0003]

SUMMARY OF THE INVENTION The present invention is intended to prevent the breakage of the lead wire by minimizing the vibration transmitted to the lead wire. Conventionally, a fixture is provided at a plurality of positions on the back surface of the outer frame. Since it was attached by a knotting method, the lead wire coming from the board and the lead wire coming from the motor and the clutch mechanism attached to the bottom of the outer tank were connected using several connectors. For this reason, not only the amount of fixtures and the like became large, but also the mounting work was time-consuming. Therefore, an object of the present invention is to provide a fully-automatic washing machine which can perform work in a simple manner and can minimize disconnection due to deflection of a lead wire.

[0004]

In order to eliminate the breakage of the lead wire due to the runout, a plurality of storage portions are provided on the side wall of the outer tub, and the lead wires pulled out from the bottom of the outer tub are stored in the storage portion. By attaching the lead wire to the substrate on the top cover, since the lead wire is integrally attached to the outer tank, the lead wire can be supported without a large swing, so that the breakage of the lead wire can be prevented. Also, do not store the lead wires up to the upper part of the storage section installed in the outer tank, and support the lead wires by entanglement etc. from the upper part of the hanging bar support of the outer frame and near the center point of the lowermost part of the hanging bar. When the lead wire is pulled up to the substrate, the suspension rod and the lead wire move in unison, so that the deflection of the lead wire is reduced and the breakage of the lead wire can be prevented. Since the number of lead wires at the bottom of the outer tub is mainly many, it becomes neat when covered with a tube or tape, so the function as a fully automatic washing machine can be improved.

[0005]

[Function] As in the prior art, when the outer frame and the outer tank are fixedly connected while the outer tank is swung, the lead wire existing between them is subjected to a large bending force without any strain. However, since the present invention can attach the lead wire integrally with the outer tank so as not to give the lead wire a large shake corresponding to the magnitude of the shake of the outer tank, the bending force applied to the lead wire can be reduced. The lead wire does not break because it can be made extremely small. Further, even if a part of the lead wire is attached to the outer tank and the other part is attached to the suspension rod, the deflection can be similarly reduced. When the lead wire is pulled from the outer tub to the top cover, the distance between the support portion of the top cover and the outer tub becomes smaller than that of the conventional one, and the runout can be minimized to prevent the wire breakage.

[0006]

1 to 3 show an embodiment of the present invention,
FIG. 1 shows a dehydration tub 6 and a rotary blade 7 provided inside an outer tub 2 in which an outer tub 2 is hung by a suspension rod 4 and a vibration-proof spring 5 inside an outer frame 1. Rotate 7 properly. A motor 8 and a clutch mechanism 9 are provided, and a drainage mechanism 10 is further provided, and a board 11 for electrically controlling them, a pressure switch 12, a lid switch 13, a water supply solenoid valve 14 and the like are stored. A top cover 15 is provided. A fully-automatic washing machine is configured by including a lead wire 20 that is electrically connected to the substrate 11 in the top cover 15 and connects the motor 8, the clutch mechanism 9, and the drainage mechanism 10. The present invention will be described in detail with reference to FIG. 1. The lead wires 20 drawn out from the motor 8, the clutch mechanism 9 and the like at the bottom of the outer tank 2 are successively inserted into a storage portion 21 provided integrally with the outer tank 2. The substrate 1 inside the top cover 15 is lifted up to the top cover 15.
It is combined with 1. Further, after the lead wire is passed through the storage portion 2la on the lower side wall of the outer tub 2, the lead wire 20 is attached to the suspension rod 4 as indicated by a virtual line 50. By doing so, the runout of the lead wire 20 swings together with the outer tub 2 and the suspension rod 4, so that the runout becomes small and the risk of disconnection of the lead wire 20 can be eliminated.

Since the lead wire at the bottom of the outer tub is mainly made up of a number of wires, it becomes neat when covered with a tube or tape, so that the function as a fully automatic washing machine can be improved. Further, according to the present invention, it is no longer necessary to fix the lead wire to the outer frame with a fixture or the like at several places in the past, and further, it is not necessary to use several connectors, which is very effective for cost reduction and production improvement. It is useful.

[0008]

According to the present invention, it is possible to prevent breakage of the lead wire by reducing the deflection of the lead wire and the bending stress and concentrated stress received by the lead wire. In addition, the work of improving the workability can be improved while eliminating the need for a lead wire fitting or the like which has been conventionally used. Therefore, it is possible to obtain a fully automatic washing machine capable of improving the function of the fully automatic washing machine and reducing the manufacturing cost.
