Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic washing machine that performs a series of washing operations such as washing, draining, rinsing, and dehydrating clothes, and more particularly to an outer tub mounting structure thereof.

2. Description of the Related Art Conventionally, a method of assembling a full-automatic washing machine of this type has been roughly divided into three sub-assemblies, and assembling them to obtain a finished product as a washing machine.

The three subassemblies are a subassembly in which components such as an electronic controller for controlling the operation of the washing machine are mounted on the operation panel and the top plate, and a board, a motor, There were a subassembly in which a drive mechanism and the like were attached and a cover and the like were attached in the upper part, and a subassembly in which legs and the like were attached to an outer box. Among these assembling methods, the subassembly of the outer tub (the anti-vibration unit is not attached) is lifted by a device such as a lift, and the anti-vibration unit is placed between the spherical receiving portion of the outer tub and the spherical receiving portion of the outer box. It was a method of attaching.

Problems to be Solved by the Invention In such a conventional configuration and assembling method, there was a problem that the vibration isolating unit could not be mounted by automatic unattended assembly.

The present invention has been made in view of the above problems, and has as its object to provide a fully automatic washing machine capable of performing automatic unattended assembly.

Means for Solving the Problems In order to solve such problems, the present invention has an outer tank for housing an inner tank, a motor drive mechanism and the like are attached to a lower part of the outer tank, and an upper part of the outer tank is provided. A cover is fixed to the upper box, and an upper spherical receiver is formed at each of the upper four corners of the outer box. It is attached to a pin formed at the end of the cover by a small hole formed in the spherical part, and a spring and packing are housed inside the lower spherical body to form an air damper part, and the lower spherical body The spherical portion has a cutout having a size that allows the diameter of the suspension rod of the vibration isolating unit to pass therethrough, and is engaged with a lower spherical receiving portion formed integrally with the outer tank, and is formed on the upper spherical receiving portion. Through the hanging bar of the anti-vibration unit through the notch, and attach the upper spherical body of the anti-vibration unit Thus, the outer tank is suspended from the outer box via the vibration isolating unit.

Operation With the above configuration, the vibration isolating unit can be mounted on the subassembly of the outer tub, and can be easily mounted on the spherical receiver of the outer box by using assembly means such as a robot.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. FIG. 6 is a vertical sectional view of a fully automatic washing machine, wherein 1 is an outer box, 2 is a top plate, 3 is a pivotally supported lid, and 4 is a series of washing, draining, rinsing, and dewatering mounted on the operation plate. It is an electronic control unit that controls the Reference numeral 5 denotes an outer tub, and 6 denotes an anti-vibration unit. The outer tub 5 is suspended from the outer box 1. 7
Denotes a substrate, which is fixed to the bottom of the outer tub 5, and a drive mechanism 9 connected via a drive motor 8 and a V-belt is fixed to the substrate 7. Reference numeral 10 denotes a washing and dewatering tub, which is fixed to a dehydrating shaft of the drive mechanism 9 via a coupling 11. Reference numeral 12 denotes a stirring blade, which is attached to the washing shaft of the drive mechanism 9. A drain valve 13 is fixed to a lower portion of the outer tank 5. 14 is a drain hose and 15 is a leg attached to the lower part of the outer box. A cover 16 is provided above the outer tank 5.
Is fixed.

FIG. 2 is a plan view of a state in which the outer tub 5 is suspended and supported by the vibration isolating unit 6 on the outer case 1 when viewed from above, and is attached to a corner of the outer case 1. Numeral 1a denotes a spherical metal fitting fixed to the corner of the outer box 1, and as shown in FIG.
1b is formed. The width of the notch 1b is set to a size that allows the diameter of the suspension rod 6b in the vibration isolation unit 6 to pass through.

Fig. 4 shows the outer box 1, the spherical fitting 1a, the upper spherical body 6a, and the hanging rod
It is a fragmentary sectional view of the attachment part of 6b.

Next, referring to FIG. 1, reference numeral 6a denotes an upper spherical body, and 6b denotes a hanging rod. After being inserted into the upper spherical body 6a, the ends are bent. A small hole 6c is formed in the spherical portion of the upper spherical body 6a, and is inserted into a pin 16a which is vertically formed at an end of the upper cover 16 of the outer tub 5.

Reference numeral 6d denotes a lower spherical body, which has a cylindrical cross section and houses a spring 6e and a packing 6f therein to form an air damper portion. The spherical portion of the lower spherical body 6d is engaged with a lower spherical receiving portion 5a formed integrally with the outer tub 5.

As shown in FIG. 6, the lower spherical receiving portion 5a of the outer tub 5 has a notch 5b formed therein, and the width of the notch 5b is set to be large enough to allow the diameter of the hanging rod 6b to pass therethrough.

According to the above-described configuration, it is possible to make a sub-assembly in which the outer tank 5 is assembled up to the anti-vibration unit 6, and when the anti-vibration unit 6 is inserted into the upper spherical metal fitting 1 a of the outer box 1,
If the notch portion 1b is assembled by using an assembling means such as a robot, unattended automatic assembling can be easily performed, and the assembling work can be greatly rationalized.

Effects of the Invention As is apparent from the following examples, according to the present invention,
Since the anti-vibration unit can be assembled to the outer tank, when assembling the outer tank into the outer box, an assembling means such as a robot can be used, and unattended automatic assembly can be performed, so that the assembling work can be greatly streamlined.
