DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehydrator for a washing machine which can be easily disassembled.

[0002]

2. Description of the Related Art Conventionally, an electric washing machine for home use is large in size when compared with other household electric appliances when the life of the washing machine has expired and the old washing machine is to be disposed of by replacement. Therefore, it is extremely difficult to dispose it or use it as recycled material. As a matter of course, processing such as reducing the size or sorting as much as possible is performed.

[0003] Incidentally, since the dewatering tub employed in recent two-tub washing machines is made of synthetic resin, it is considered to utilize the material as a recycled material.
In the dewatering tank, a balancer in which a liquid is sealed is fixed to an upper end of the dewatering tank in order to correct imbalance caused by uneven load during dehydration. For this reason, when this is decomposed, it is necessary to remove the liquid in the balancer in advance.
Conventionally, in this operation, the balancer was cut using a special tool, but the operation was troublesome.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to discharge a liquid in a balancer portion very easily without cutting or destroying the balancer portion. It is an object of the present invention to provide a dehydrating device for a washing machine that can perform the washing.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a dehydration tub comprising a bottomed cylindrical body and a ring-shaped balancer fixed to the upper end thereof and containing liquid therein. Is formed with a protruding portion integrally formed with the balancer portion and a thin-walled broken portion surrounding the protruding portion.

[0006]

According to the above-mentioned means, only by striking the protrusion formed on the balancer portion of the dewatering tub, the broken portion around the cut portion is cut and opened as a hole, so that the liquid in the balancer can be easily discharged from here. Can be discharged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIG. 5. Reference numeral 1 denotes a two-tub washing machine, and first, a steel plate formed in a rectangular cylindrical shape. The bottom is closed by a base 5 to which a washing motor and a dehydrating motor 3 not shown are fixed via an elastic support 4, and a washing timer 6, a switching cock 7, a water supply port 8, a dehydrating An operation panel 10 having a timer 9 and the like is mounted and fixed. Inside the outer box 2, a washing tub 11 and a dehydration receiving tub 12 are provided.
Is housed alongside. A stirring blade 13 is provided on the inner bottom surface of the washing tub 11 so as to be rotationally driven by a washing motor, and a overflow filter 14 and a drain filter which separate the front surface of the overflow drainage chamber from the washing tub 11 are provided at the right rear corner. It is divided by 15. On the other hand, the dewatering tank 16 is
Is connected to the dehydration motor 3 by a connector 17 and a bolt 18 and is rotatably provided so as to be directly driven. As shown in FIG. 1, the dewatering tub 16 is entirely made of synthetic resin, is formed in a cylindrical shape with a bottom, and has a number of small holes 19 in the peripheral wall.
And a ring-shaped balancer portion 22 fixed to the upper end thereof and containing a liquid 21 made of salt water therein.
It is composed of 2 and 3, a short columnar projection 23 as shown in FIG. 2 and FIG.
2 and a cut-out portion 24 formed by forming a groove on the inner surface of the balancer portion 22 and making it thinner in a C-shape that goes around the protrusion 23 while leaving a part thereof. I have. The thickness of the broken portion 24 is half or less of the other portions. In addition, on the surface of the break portion 24, an indication 25 of "water drainage" is formed by a mold. 26 is a drain hose.

When disassembling the two-tub washing machine constructed as described above, the disassembly of the dewatering tub 16 particularly relating to the present invention will be described. First, the operation panel 10 fixed by screwing is removed from the outer box 2 and the upper part of the dehydration receiving tank 12 is opened. Next, the bolts 18 of the connector 17 connecting the dehydration motor 3 and the dehydration tub 16 are loosened below the dehydration receiving tub 12, and the dehydration tub 16 is pulled out to a single state as shown in FIG. And the balancer part 2 of the dewatering tank 16
2. When the protrusion 23 on the upper surface is hit with a hammer or the like, the broken portion 24 is substantially circularly depressed as shown in FIG. 4 and is only partially connected to the balancer portion 22. Become. This operation is performed for the two break portions 24 to keep the open state. As a result, the liquid 21 in the balancer section 22 can be easily and smoothly discharged from one of the openings, so that the dewatering tank 16 can be incinerated as it is or processed as a recycled material.

On the surface of the balancer portion 22 near the break portion 24, a letter "water drainage" is formed by molding as an indication 25 indicating that the break portion 24 is present. That is, it is immediately understood that the liquid 21 should be drained from here, and the processing operation can be performed more smoothly.

FIGS. 6 and 7 show a second embodiment of the present invention. Only parts different from the first embodiment will be described.
The upper surface of the balancer portion 22 at the portion where the protrusion 23 is located is formed as a disk-shaped thin portion centered on the protrusion 23 formed integrally with the balancer portion 22, thereby forming a break portion 27.

FIGS. 8 and 9 show a third embodiment of the present invention. The upper surface inside the balancer portion 22 where the protrusion 23 is located is centered on the protrusion 23 formed integrally with the balancer portion 22. FIG. The point is that the wall thickness is gradually reduced from the large-diameter circle as a starting point toward the root of the projection 23, thereby forming the broken portion 28.

FIGS. 10 and 11 show a fourth embodiment of the present invention. Only parts different from the first embodiment will be described. The point is that a thin portion is formed by an inverted V-shaped groove surrounding the protrusion 23 formed integrally with the balancer portion 22 in a circle around the protrusion 23, thereby forming a break portion 29.

In the second to fourth embodiments, similarly to the first embodiment, when the protrusion 23 is hit with a hammer or the like, the break portions 27, 28 and 29 are depressed into a substantially circular shape and the balancer portion is depressed. 22 is opened as a hole. As a result, the liquid 21 in the balancer section 22 can be easily and smoothly discharged from the opening, so that the incineration or the processing as a recycled material can be easily performed.
In particular, in the third embodiment, since the break portion 28 is inclined toward the opening, the liquid 21 inside can be discharged more smoothly.

In each of the above embodiments, the projecting portion 23 is hit hard with a tool such as a hammer.
The method of breaking 4, 27, 28, 29 is not limited to this, and it is of course possible to use only the force of the hand.
Needless to say, a configuration in which 7, 28, and 29 are cut may be employed.

[0015]

As apparent from the above description, the dehydrating apparatus for a washing machine according to the present invention has the following excellent effects.

That is, according to the dehydrator of the washing machine of the first aspect, only the striking part 23 formed integrally with the balancer part 22 of the dehydrating tub 16 is hit hard, so that the broken parts 24, 2 around it are formed.
7, 28 and 29 are cut to open holes, so that the liquid 2 in the balancer section 22 can be very easily cut from here without cutting or breaking the balancer section.
1 can be discharged.

According to the dehydrator for a washing machine of the second aspect, the display 25 of "water drainage" formed on the surface in the vicinity of the break portions 24, 27, 28, 29 of the balancer portion 22 indicates that this is the break portion. Yes, it is immediately understood that the liquid 21 should be drained from here, and the processing operation can be performed more smoothly.
