[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine, and more particularly to a structure for accommodating foreign matter such as coins coming out of laundry.

[0002]

2. Description of the Related Art For example, in a fully automatic one-tank type washing machine, as shown in FIG. 9, a water tank 2 is swingably supported in an outer box 1 via a vibration isolator (not shown). A washing and dewatering tub 4 having a rotating blade 3 at the bottom is rotatably disposed in a water tub 2, and a ring-shaped balancer 5 is provided on an upper opening edge of the washing and dewatering tub 4. In the figure, reference numeral 6 denotes an opening for loading the laundry provided at the upper part of the outer box 2; 7 a lid for closing the opening 6; 8 a washing and dewatering from the periphery of the rotary wing 3 to the upper part of the washing and dewatering tub 4; 3 shows a circulation channel formed in the water tank 4.

In order to perform washing, the lid 7 is opened, laundry is put into the washing and dewatering tub 4 through the opening 6, the contents of the washing are set, and when the lid 7 is closed, water supply and rotation of the rotor 3 are performed. The entire process of washing, rinsing, and spin-drying by the high-speed rotation of the rotating blades 3 and the washing and spin-drying tub 4 automatically proceeds.

Meanwhile, during the washing, foreign matter such as coins in the pocket of the laundry jumps out of the pocket in the washing and rinsing process, and the coins 10 and the like are washed by the rotating wings 3 into the washing and dewatering tub 4. It moves on the side wall of the washing and dewatering tub 4 along the water flow created therein, sinks further by weight, and enters the gap 9 between the rotary wing 3 and the bottom of the washing and dewatering tub 4 as shown in FIG. .

[0005]

The coin 10 that has entered the gap 9 between the rotor 3 and the bottom of the washing and dewatering tub 4 comes into contact with the rotor 3 and the rotation of the rotor 3 is locked. Caused an error.

In particular, when the washing machine is fully automatic, the lid 7 is not opened until the final spin-drying process is completed. During this time, the coins 10 remain in the gap 9 and an error easily occurs. And when it jumps out of the gap 9 by centrifugal force during the spin-drying process, it collides with the inner wall of the washing and spin-drying tub,
It also causes noise.

[0007] Further, even if it is recognized in the middle of washing that the coin 10 has been caught in the gap 9, as shown in FIG.
Is in a state in which the upper part is slightly looking through the narrow gap 9, and it is difficult to pick out and remove the coin 10 with a fingertip.

An object of the present invention is to solve the above-mentioned disadvantages of the prior art, and to prevent the foreign matter such as coins coming out of the laundry during washing from entering the gap between the rotating wing and the bottom of the washing and dewatering tub to rotate the rotating wing. Locking is prevented, and coins sinking at the bottom of the washing and dewatering tub are easily taken out. In addition, coins sinking at the bottom during the washing process etc. fly out by centrifugal force during the dewatering process and the inner wall of the washing and dewatering tub Another object of the present invention is to provide a washing machine capable of preventing the occurrence of a washing machine.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention firstly provides a washing machine in which a rotating blade is disposed at the bottom of a washing and dewatering tub. A concave portion for accommodating foreign matter from the laundry is formed around the wing, and a water drain hole is formed in the concave portion, so that foreign matter such as coins moved to the bottom of the washing and dewatering tub can be removed from the concave portion. Go inside and be housed here during the laundry. Therefore,
Coins and the like do not enter the gap between the rotor and the bottom of the washing and dewatering tub, thereby preventing rotation errors of the rotor. In addition, since the recess is provided with a drain hole, water can be prevented from accumulating in the recess during the dewatering process.

Secondly, since the concave portion for accommodating foreign matter has the bottom surface formed in the upper and lower steps, foreign matter such as coins is horizontally accommodated in the concave portion. Since a gap is formed between the first and second portions, if the coin is pushed from above in the lower direction, the coin is inclined and the end protrudes upward from the concave portion. Therefore, if this protruding portion is pinched with a fingertip, it can be easily taken out from the concave portion.

Thirdly, the concave portion for accommodating foreign matter has a bottom surface formed on a horizontal portion and a downward inclined portion connected to the horizontal portion, so that foreign matters such as coins are horizontally accommodated in the concave portion and are formed on a horizontal surface. Even if the rider comes in close contact, a gap is formed between the coin and the inclined surface. Therefore, if the coin is pressed from above in the direction of the inclined surface, the coin is inclined and the end protrudes upward from the concave portion. Therefore, if this protruding portion is pinched with a fingertip, it can be easily taken out from the concave portion.

Fourthly, by forming a recess for inserting a finger at a position lower than the bottom of the recess in connection with the recess for accommodating foreign matter, the bottom of the recess has a flat surface so that the coin comes into close contact therewith. Even if the coins are stored, if a fingertip is inserted into a recess for finger insertion at a position lower than here, the coin can be easily pulled up from below with the fingertips.

Fifth, the drainage hole is formed near the side wall of the concave portion, and has a flat shape corresponding to the planar shape of the drainage hole below the drainage hole and opposed to the drainage hole. By providing the protruding portion, even if a thin foreign matter such as a needle or a pin is to be discharged from the drain hole, it hits the protruding portion that is protruding below it and can be prevented from being locked there and discharged.

Sixth, since the drain hole is a lattice-like body formed at the bottom of the concave portion, the drain can be drained over the entire bottom and the drain can be smoothly performed.

Eighth, a protrusion is provided at the upper opening edge of the recess for accommodating foreign matter on the side wall of the washing and dewatering tub so as to prevent the foreign matter accommodated in the recess from jumping out. This prevents the foreign matter contained in the container from jumping out by centrifugal force during the dehydration process.
