Description

[Detailed Description of the Invention] The present invention relates to a synthetic resin outer tank containing a washing and dehydrating tank that is suspended from a machine frame using a hanging rod, and one pair of the seats of the hanging rod are integrated into the outer tank. At the same time, the other pair is integrally molded on both ends of a horizontally long mounting base for attaching electrical components such as motors and bearing cases, reducing costs and simplifying the manufacturing process by reducing the number of parts. This is what we are trying to do.

This will be explained below based on the drawings.

Figures 1 and 2 show a conventional example, in which an outer tank 3 with a washing and dehydrating tank 2 installed inside the machine frame 1 is suspended at its upper end by a hanging rod 4 supported by the machine frame 1. There is.

Specifically, a bearing case 5 attached to the bottom of the outer tank 3 has arms 6 protruding from all sides, and a support arm 7 fixed to the arms 7 has a support arm 7 integrated with a seat 8 for receiving the hanging rod 4 at the upper end thereof. The outer tank 3 is suspended in a vibration-proof manner by a hemispherical body 9 and a spring 10 interposed between the lower end of the hanging rod and the seat 8.

Further, two mounting arms 11, 11 are bridged in parallel between the arms 6 and 6, sandwiching the bearing case 5.
．． Electrical components such as motors 13 and 14 for driving the dehydration tank 2 and the rotary blade 12 are installed between 11 and 11.

In such a conventional device, the support arm 7 for suspending the outer tank and the mounting arm 11 for attaching electrical components are attached to the bearing case 5.
Because they were fixed separately to each other, there were a large number of parts and many mounting points (which resulted in high costs and increased assembly man-hours).

The present invention has been made in view of this point, and will be described below with reference to FIGS. 3 to 5.

As is clear from FIG. 3, a horizontally elongated metal mount 17 with a longitudinal section in the opposite longitudinal direction is attached to the bottom of the synthetic resin outer tank 16 in which the washing and dehydration tank 15 is installed using screws 18. A seat 20 for a hemispherical suspension rod 19 is integrally formed on both longitudinal ends of the mounting base 17 that protrude outward from the outer tank 16, and a hemispherical body 21 that fits into the seat 20; The outer tank 16 is suspended by a spring 22 in a vibration-proof manner.

Also, hanging rod supports 23, 23 having the same shape are integrally molded on the outer tank 16 in a direction perpendicular to the line connecting the above-mentioned supports 20 and 20, and the outer tank 16 is suspended at these four points. has been done.

An upper bearing 250 and a case 26 that pivotally support the dehydration tank drive shaft 24 are integrally formed in the center of the mounting base 17, and a lower bearing 270 and case 28 are bent at both ends of the mounting base 170 in the non-longitudinal direction. It is attached to the flange portions 29 and 29 with screws 30.

31 is an annular sealing body that seals between the dehydration tank shaft 24 and the upper case 26 and between the case 26 and the outer tank 16.

Furthermore, electric components such as a motor 33 for driving the dehydration tank 15 and the rotary blade 32, a drain valve 34, and a solenoid 35 for operating the valve 34 and a brake device and a clutch device (not shown) are attached to the flange portions 29, 29. It is being

In FIG. 5, reference numeral 36 is an operating rod for operating the drain valve 34 by means of a solenoid 35, 37 is an operating lever that operates in conjunction with the operating rod 36 to operate a brake device or a clutch device, and 38 is a belt.

As is clear from the figure, a motor 33, a drain valve 34, a solenoid 35, etc. are attached to the flange portions 29, 29, with the lower bearing case 28 as the center, separated into left and right parts.

FIG. 6 shows another embodiment of the mounting base 17, in which the flange portion 2
In order to increase the strength of the U-shaped bent portions for forming the U-shaped portions 9 and 29, drawn bent portions X, Y, and Z are provided, and the pitch A of the screw holes 18' for mounting to the outer tank is increased (This increases the strength of attachment to the outer tank.

As described above, in the present invention, a horizontally long mounting base is attached to the bottom of the outer tank, electrical components such as a motor and a bearing case are attached to the flange of this mounting base, and four hanging rods are attached to both ends of the mounting base. The seats for two of the hanging rods are integrally molded, and the seats for the remaining two hanging rods are integrally molded into the outer tank, making it possible to replace the existing suspension rods (with mounting arms for attaching electrical components and seats for the hanging rods). There is no need to prepare support arms separately, and there is no need to fix them to the bearing case (the mounting base is simply attached to the outer tank, so the number of parts can be significantly reduced).

In addition, there are fewer mounting points, making assembly easier.

Furthermore, only two of the four hanging rod seats are formed on the mounting base,
Since the remaining two catches are integrally molded with the outer tank, there are four seats on the mounting base.
Unlike molding all the individual seats as one piece, the mounting base is easier to process and is also lighter in weight, making it possible to significantly reduce costs overall.

In addition, the mounting base is different from a flat plate in that it has mounting flanges bent at both ends in the force direction, so the entire structure is reinforced and durable, making it easy to install motors, bearing cases, etc. The situation can be solidified.

Moreover, the flange part, which is the mounting part for the motor, bearing case, etc., has a sufficient distance from the bottom of the outer tank.
After installing the motor etc. with screws, these mounting parts are
The tube can be easily removed by inserting a tool into the space between the flange portion and the bottom of the outer tank and loosening the screw, making the tube highly serviceable and providing various excellent effects.
