Description

[Detailed description of the invention] The present invention consists of a dewatering/washing tub with a non-porous peripheral wall, and a recess formed outwardly from the bottom of the dehydrating/washing tub to the top of the peripheral wall so as to communicate with the pulsator installation part. This invention relates to a sand discharge device for a washing machine that also serves as a dewatering machine, and is equipped with a circulation type bypass passage provided with a lint filter on the upper part. The purpose is to provide a structure that can be obtained by

Hereinafter, the present invention will be explained based on drawings showing embodiments thereof.

In Figures 1 to 3, reference numeral 1 denotes a dewatering/washing tub with a non-porous surrounding wall and a large number of dewatering grooves 1' formed vertically. 2 is installed.

3 is a pulsator installation part provided at the bottom of the dehydration/washing tub 1, and this pulsator installation part 3 has a rotatable pulsator 4.
has been established.

Reference numeral 5 denotes a circulation type bypass path constituted by a recess 7 projecting outward from the bottom of the dewatering/washing tub 1 to the top of the peripheral wall so as to communicate with the pulsator installation part 3 through a communication hole 6. The type bypass path 5 has a lint filtration applicable filter 8 which protrudes into the dewatering/washing tub 1 at its upper part and is detachably installed therein.

Further, the recess 7 is formed wide in the lateral direction, and 9 is a sand discharge passage provided with a partition 10 in the recess 7 and arranged in parallel with the circulation type bypass passage 5. An opening 11 that does not communicate with the pulsator installation section 3 and is located above the rated water level of the dewatering/washing tub 1 is provided at the top.

In addition, a filter 13 having a large number of holes 12 is detachably installed in an intermediate portion 9' of the sand discharge path 9 located at the bottom of the dewatering/washing tub 1.

Reference numeral 14 denotes a single blocker that closes the openings of the recesses 7 constituting the circulation bypass path 5 and the sand discharge path 9, and this blocker 14 is detachably mounted.

The operation in the above configuration will be explained.

First, lint generated during washing is transferred from the pulsator installation section 3 to the circulation type bypass path 5 through the rotation of the pulsator 4. Since a circulating water flow reaching the inside of the dewatering/washing tub 1 is formed through the lint filter 8, the lint coming out of the laundry during washing is reliably collected by the lint filter 8.

Further, sand and the like mixed in the laundry are separated from the laundry during washing and accumulate at the bottom of the dewatering/washing tub 1.

At this time, as the laundry rotates, sand and the like will simultaneously rotate at the bottom of the dewatering/washing tub 1, but this sand, etc. will flow through the hole 12 of the filter 13 to the bottom of the dehydrating/washing tub 1 in the sand discharge path 9. While in position, it falls into part 9' and is captured.

During spin-drying, the trapped sand and the like are discharged from the spin-drying/washing tub 1 through the sand discharge path 9 along with the water through the opening 11 due to the high-speed rotation of the spin-drying/washing tub 1.

FIG. 4 shows an embodiment in which the filter 13 of the sand discharge channel 9 is formed integrally with a single blocker 14. In this embodiment, the number of parts can be reduced, so The mold is also cheaper.

As described above, according to the present invention, the four openings that make up the circulation bypass path and the sand discharge path are closed by one blocker through the partition, so that the circulation bypass path and the sand discharge path can be Compared to arranging the sand discharge channels independently and blocking each with a separate blocker, the number of parts can be reduced, and as a result, the cost of the mold can be lowered. It is.
