2. Description of the Related Art Conventionally, in a two-tub type washing machine, detergent and laundry are put into the washing tub and then water is supplied, and stirring blades provided on the bottom of the washing tub are alternately rotated right and left at predetermined intervals. A swirling water stream is generated so that the laundry is stirred and washed.

At this time, dust and the like floating in the water are quickly overflowed and discharged from the overflow chamber formed in the inner corner of the washing tub to prevent reattachment to the laundry. An overflow strainer 26 as shown in FIG. 3 is attached to the front surface of the overflow chamber so as not to flow into the overflow port. The overflow strainer 26 has a large number of small holes 27 for catching lint, and a lint catching net 28 whose opening direction changes according to the water flow is provided from a high water level which is a prescribed water level to a low water level. It is rotatably held. Further, since the operation box is placed above the overflow chamber, the overflow strainer 26 must be detached from the open front side of the overflow chamber, and the lower fixing claw 30 is first attached to the lower surface of the overflow chamber. After the engagement, the elastic engaging claws 29 on the side portions are deformed and engaged with the side surface of the overflow chamber for attachment.

However, if the elastic engaging claws 29 are not properly engaged, the elastic engaging claws 29 may be easily disengaged by the impact of the laundry, or in an extreme case, the elastic engaging claws 29 may be broken. If the elastic engagement claw 29 is broken, a broken piece may be clogged in a drain valve or the like to cause a malfunction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Reference numeral 1 is an outer box of a two-tub washing machine formed by bending a steel plate into a rectangular tube shape, the bottom surface of which is closed by a base (not shown) to which a washing motor, a dehydration motor, etc. are fixed, and a bottomed rectangular tube. A tub body 4 having a washing tub 2 and a dehydration receiving tub 3 arranged side by side is housed in the outer box 1.
An operation box 8 having a washing timer 5, a switching cock 6, a dehydration timer 7 and the like is placed and fixed on the upper surface of the rear portion of the tank body 4. A stirring blade 9 is provided on the inner bottom surface of the washing tub 2 so as to be rotationally driven by the above-mentioned washing motor, and the right front corner of the washing tub 2 bulges outward to overflow the water. Is formed. This flood chamber 10
An overflow pipe 11 is erected inside the tank so as to communicate with the outside of the tank via its bottom surface, and water overflowing from the overflow pipe 11 is led out of the machine from a drain hose 12.
The overflow strainer 13 is detachably attached so as to partition the front opening of the overflow chamber 10 from the washing tub 2. The overflow strainer 13 is made of a synthetic resin and is vertically long with a large number of water passage holes 14, and in the middle thereof, like the conventional overflow strainer 26 shown in FIG. 3, it extends from a high water level as a regulated water level to a low water level. The yarn waste catching net 15 is rotatably held so that its opening direction changes. Then, on both sides of the overflow strainer 13, slides made of vertically elongated ribs 17 are engaged so as to be engaged with sliding portions formed as vertical grooves 16 at both ends of the front opening of the overflow chamber 10. The portion is integrally formed in a stepped shape with the main body of the overflow strainer 13.

On the other hand, at the upper opening edge of the washing tub 2, there is an L-shaped eave-shaped water blocking member 18 projecting inwardly of the washing tub 2 from the left side portion to the front side portion thereof. Dewatering hatches 20, whose laundry inlets and outlets can be opened and closed by an inner lid 19, are fixed to the upper surface of each by means of screws or the like.

Reference numeral 21 is an overflow hatch for closing the upper surface of the overflow chamber 10 in a substantially triangular shape, and the hinge shaft 2 is provided at both ends on the front side.
2 is sandwiched by a receiving portion 23 formed by the right end of the water-impervious member 18 and the left end of the dehydration hatch 20 and the upper end of the washing tub 2, and the tip is on the tub body 4 side. An elastic claw 25 that engages with the formed engagement hole 24 is provided upright, and is supported by the elastic claw 25 so as to be openable and closable while maintaining a closed state.

The operation of the overflow device of the two-tub type washing machine thus constructed will be described below. First, the detergent and the laundry are put into the washing tub 2, and the washing timer 5 is set after supplying water up to the specified water level, and the stirring blade 9 is controlled by this and the stirring blade 9 is reversed right and left at regular intervals to start the washing process. To be done. As a result of this washing process, the water in the washing tub 2 rotates together with the stirring blade 9 to generate a swirling water flow, so that the laundry flows within the washing tub 2 along with the water flow, and the stirring blade 9 and the wall surface of the washing tub 2 overflow water. Friction is generated by hitting the strainer 13 and the like, so that a cleaning action can be obtained. At that time, dust such as lint and the like is generated from the laundry and floats in the water, but they are caught by the overflow water strainer 13 and are prevented from reattaching to the laundry. In addition, when flood rinsing is performed in the rinsing process after the washing process, the overflow water is discharged from the overflow pipe 11 of the overflow chamber 10 to the outside of the machine, at which time the laundry flows out by the overflow strainer 13. It is supposed not to.

Since the waste water strainer 13 accumulates lint and the like each time it is repeatedly washed, it must be removed and cleaned from time to time. As the procedure at that time, first, the overflow hatch 21 is rotated by removing the elastic claw 25 from the engagement hole 24, and the upper surface of the overflow chamber 10 is opened. Then flood water strainer 13
Is pulled upward along the sliding portion 16 of the flood chamber 10,
Remove from the wash tub 2. When reattaching after cleaning, reverse the procedure of removal, and engage both ribs 17 on both sides of the overflow strainer 13 into the groove 16 of the overflow chamber 10 and push down until it stops. After that, the overflow hatch 21 is closed, the elastic claw 25 is engaged with the engagement hole 24 to prevent the overflow strainer 13 from being pulled out upward, and thus the cleaning of the overflow strainer 13 is completed.
