Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sand discharge device for a washing machine with a dewatering and washing machine equipped with a washing and dewatering tub with a non-porous peripheral wall.

A conventional sand discharge device of this type was constructed as shown in FIGS. 5 to 7.

That is, 11 is a dehydrating washing tub having a large number of dehydrating grooves 11' on the peripheral wall, 12 is a pulsator provided at the bottom of the dehydrating/washing tub 11, and 13 is a pulsator located beside the pulsator 12 at the bottom of the dehydrating/washing tub 11. A plug body 14 is detachably attached to the discharge hole 13 provided in the discharge hole.

In this configuration, washing is carried out with the plug 14 attached to the discharge hole 13 as shown in FIG. It separates and accumulates at the bottom of the dewatering/washing tub 11.

When sand and the like accumulated at the bottom are to be discharged, the plug 14 is removed as shown in FIG. 7, and the sand and the like are flushed out from the discharge hole 13 with water.

Therefore, with this configuration, whenever sand or the like accumulates at the bottom of the spin-drying/washing tub 11, it is necessary to remove the stopper 14 and flush it out with water, which is extremely time-consuming and requires removal. There was a risk that the plug body 14 that had been removed would be lost.

In view of the above-mentioned conventional problems, the present invention aims to provide a structure that can capture sand, etc. mixed in laundry during washing, and automatically discharge it during spin-drying. will be described based on drawings showing examples thereof.

In Figures 1 and 2, reference numeral 1 denotes a dewatering/washing tub with a non-porous surrounding wall and a large number of dewatering grooves 1' formed in the vertical direction. 2 is installed.

3 is a rotatable pulsator provided at the inner bottom of the dewatering/washing tub 1; 4 is a recess for storing sand provided at the bottom of the dehydrating/washing tub 1, independent of the recess for housing the pulsator 3; Reference numeral 5 denotes a sand discharge path that protrudes outward from the peripheral wall of the dewatering/washing tub 1. At the top of the sand discharge path 5, there is a discharge port located above the rated water level of the dewatering/washing tub 1. There are 6.

Further, the independent recess 4 for storing sand is a sand discharge path 5.
It communicates with

Reference numeral 7 denotes a filter detachably installed in one of the independent recesses 4, and this filter 7 is provided with a large number of holes 8.

In the above configuration, the operation will be explained based on FIG. 2.

First, during washing, sand and the like mixed into the laundry separate from the laundry and accumulate at the bottom of the dehydration/washing tub 1.

At this time, due to the rotation of the laundry, sand 9, etc. will simultaneously rotate at the bottom of the dewatering/washing tub 1, but this sand 9, etc. will be transferred from the hole 8 of the filter 7 into the independent recess 4 as shown by arrow A. falls and is captured.

The sand 9 and the like captured in this recess 4 do not return to the spin-drying/washing tub 1 again due to the washing water flow, and during spin-drying, the sand 9 and the like are collected together with water by the high speed rotation of the spin-drying/washing tub 1 as shown by the arrow. It passes through a discharge path 5 and is discharged to the outside of the dewatering/washing tub 1 from a discharge port 6.

FIGS. 3 and 4 show another embodiment of the present invention, and the difference from the embodiment shown in FIGS. 1 and 2 is that the sand discharge path 5 is A part of the peripheral wall of the filter 7 is formed by a concave groove 5' projecting outward, and the filter 7
In addition, a blocker 7a is integrally formed to close the opening 5a' of the groove 5' constituting the sand discharge path 5. By attaching the closing body 7a to the opening 5a of the groove 5'
' is closed to form a sand discharge path 5.

With this configuration, if the sand discharge path 5 should become clogged, the filter 7 can be removed to easily remove and clean the foreign matter.

As described above, according to the present invention, an independent recess for collecting sand is provided at the bottom of the dewatering/washing tub, and this recess is communicated with the sand discharge path having a discharge port on the outside above the dehydrating/washing tub. Since a filter with a large number of holes is installed on the upper surface of the recess, sand, etc. mixed in the laundry is captured in the recess during washing, and does not return to the dehydration/washing tub due to the washing water flow. In addition, the sand can be automatically discharged through the sand discharge path during dewatering, and as a result, the conventional labor and effort is unnecessary, so the practical effect is extremely large.
