[Detailed Description of the Invention] Industrial Application Field The present invention relates to the structure of a centrifugal dehydrator in a two-tub washing machine used in general households.

Conventional structure and its problems Generally, the centrifugal dehydrator of a two-tub washing machine has a brake device to brake the centrifugal dehydrator which continues to rotate by inertia even after the dehydration is completed. It has a structure that operates via a hinge part that interlocks the opening and closing of the receiver lid.

The structure of a conventional centrifugal dehydrator is as shown in FIG. Reference numeral 1 denotes an outer tank, inside of which a dehydration receiver 2 is fixed, and further inside thereof, a centrifugal dehydration basket 3 is arranged. A coupling ring 4 connects the dehydration basket 3 and the dehydration shaft 5. The dewatering shaft 5 passes through a waterproof and anti-vibration bellows 6 and is fixed to the brake wheel 7 with screws. 8 is a motor, and suspensions 9 and 10 serve as anti-vibration and insulation.
By fixing the shaft 11 to the brake wheel 7 with screws,
The rotational force is transmitted to the dehydration basket 3 through the dehydration shaft 5 and the coupling ring 4. 12 is a brake lever rotatably attached to a plate member 13 fixed to the motor 8. Reference numeral 14 denotes a lid made of synthetic resin or the like so as to communicate with the opening/closing of the dehydration receiver lid 15. Reference numeral 16 denotes an inner wire that interlocks the lid cover 14 and the brake lever 12, and retaining rings 17 are attached to both ends to prevent the wire from coming off.

As shown in FIG. 2, the lid 14 is
It has a plurality of ribs 18 that serve both as reinforcement and for positioning a wire mounting plate, which will be described later, and has a through hole 19 for the inner wire 16 in the center. Further, the rear portion has a hook portion 22 that engages with a mounting hole 21 provided in the dewatering receiver 2 via a thin hinge portion 20. Reference numeral 23 denotes a wire mounting plate made of a steel plate or the like, and the retaining ring 17 of the inner wire 16 is engaged with this wire mounting plate 23. As a result, the retaining ring 17 is attached to the through hole 1 of the lid cover 14.
This prevents the hole 19 from being worn or damaged by directly contacting the hole 9. 24 is an inner wire through hole of the dewatering receiver 2.

In the above configuration, when assembling the bottom part, first insert and engage the hook part 22 of the lid holder 14 into the mounting hole 21 of the dewatering receiver 2 by utilizing its flexibility, and then attach the wire mounting plate 23 to the lid holder 14. the inner wire 16 is passed through the through hole 19, and the retaining ring 17 is placed on the wire mounting plate 23.
All you have to do is engage it.

However, in the above configuration, the dehydration receiver lid 1
Since the hinge portion 20 curves and deforms as the device 5 is opened and closed, there is a drawback that the hinge portion 20 deteriorates and is damaged due to repeated use over a long period of time. In addition, for the above-mentioned reason, the wire mounting plate 2
3 is required, and the hook portion 22 may come off from the mounting hole 21 of the dewatering receiver 2 due to shocks such as vibration during transportation or dropping during handling. Furthermore, places with high humidity such as bathrooms and balconies,
Or, if the washing machine is used in a place with large temperature changes, the dehydration receiver cover 15 and the lid cover 14 may
Since they are all made of synthetic resin or the like, they are often deformed and have the disadvantage that the brake device cannot be operated stably.

Purpose of the invention The object of the present invention is to eliminate the above-mentioned drawbacks, and to provide a chamber structure for a centrifugal dewatering machine that is simple in construction, secure in installation, and allows stable operation of the brake device.

Structure of the Invention In order to achieve the above object, the present invention has been developed in a central part of a centrifugal dehydrator in which the centrifugal dehydration basket is braked by an inner wire that communicates with the opening and closing of the dehydration receiver lid, and is applied around the inner wire passage hole of the dehydration receiver. A support member having a protrusion in the center at an intermediate position between the front and rear walls of the rib is provided extending between the left and right walls of the rib, and a support member having a gap between the support member and the support member. The locking member is provided at the upper end of the rear wall of the rib, and is further formed with a fitting hole that engages with the protrusion, is supported by the support member, and has its tip end connected to the support member from below. One plate part that can be locked and has a through hole for engaging the inner wire formed therein, and a curled part that is bent downward from the one plate part in a substantially L shape, and whose tip part slides into contact with the dehydration receiver lid from above. A substantially L-shaped metal lid having a sliding contact portion and the other plate portion is provided such that the bent portion is located upward, and the inner wire is between the front wall of the rib and the lid support member. The inner wire engagement through hole of the lid cover is configured to be engaged through the inner wire engagement hole through the inner wire engagement hole.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 and 4, with some reference numerals overlapping those of the conventional example.

In FIGS. 3 and 4, reference numeral 2 denotes a dewatering receiver, which has a through hole 25 for passing an inner wire, and a rib 26 is erected around the through hole 25. Front and rear walls 2 of rib 26
The left and right walls 26 of the rib 26 at the intermediate position between 6a and 26b
A support member 28 having a protrusion 27 in the center is provided across between c and 26d.
Further, at a position close to the support member 28, a support locking member 29 having a flat lower surface is provided at the upper end of the rear wall 26b of the rib 26 toward the support member 28 side. As a result, a gap 30 is formed between the cover locking member 29 and the protrusion 27, which is large enough to allow insertion of a cover cover, which will be described later.

Reference numeral 31 denotes a lid, which is made of a plate-shaped metal material such as a steel plate and is formed into a substantially L-shape, and has a substantially L-shaped bent portion at the top. A through hole 33 for engaging the inner wire is formed in the L-shaped one plate portion 32 near the bent portion, and a retaining ring 1 of the inner wire 16 is formed in the L-shaped one plate portion 32 .
A cut-and-raised portion 34 is formed as a stopper for 7, and a fitting hole 35 that engages with the projection 27 is formed near the end portion 36, and a cut-and-raised portion 37 that slides into contact with the projection 27 is formed. . The end portion 36 can be locked to a locking member 29 from below. Further, at the tip of the other L-shaped plate portion 38, a curled sliding contact portion 39 is formed to slide into sliding contact with the dehydration receiver lid from above. In addition, the inner wire 16 locked by the retaining ring 17 is attached to the rib front wall 2.
6a and the support member 28 and extends downward toward the brake lever.

To explain the assembly, first, the end portion 36 of the lid cover 31 is inserted into the gap 30, and then the protrusion 27 is inserted into the insertion hole 35. Then, after inserting the inner wire 16 into the inner wire engagement through hole 33, it is only necessary to engage the retaining ring 17 with the cut and raised portion 34 of the lid cover 31.

According to such a configuration, due to the inclination of the L-shaped portion with the bent portion of the lid facing upward,
It is possible to securely fix the retaining ring of the inner wire so that it will not come off, and the structure is simplified as the conventional wire mounting plate 23 is no longer required.
The end portion 36 of the lid is securely pressed from above, and even if there is an impact force such as dropping during transportation or handling, the lid will not come off from the predetermined position. Even if the dehydration receiver lid 15 is slightly deformed during long-term use, the lid 3
Since the sliding contact portion 39 of No. 1 has a curled shape, the sliding contact portion 39 is always in contact with the dewatering container lid 15 at any position, and only the position of the sliding contact point with the dehydration receiver lid 15 changes, resulting in stable operation. Brake equipment can be operated.

Effects of the invention As described above, according to the invention, the inclination of the L-shaped part in which the bent part of the lid is arranged upward makes it possible to reliably fix the retaining ring of the inner wire so that it does not come off. This eliminates the need for a wire mounting plate, simplifying the structure, and the locking member securely holds the end of the lid from above.
Even if there is an impact such as dropping during transport or handling, the lid will not come off the designated position, and even if the dehydration receiver lid is slightly deformed during long-term use, the sliding part of the lid will not come off. By simply changing the position of the sliding contact point with the dehydration receiver lid, stable braking operation can be achieved.
