Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dehydrating washing machine capable of washing and dewatering items to be washed.

[Prior Art] Conventionally, the following two types of washing machines have been known as typical configurations.

The first type consists of an aquarium, a dehydration tank supported rotatably around a vertical axis within the aquarium, and a dehydration tank with a number of small holes perforated in the surrounding wall, and a dehydration tank rotatably supported around a vertical axis within the dehydration tank. Equipped with rotatably supported stirring blades, by rotation of the stirring blades,
This dehydrating washing machine not only washes the items to be washed, but also dehydrates the items after washing by rotating the dehydrating tank at high speed.

The second type includes an aquarium and a rotating drum that is rotatably supported around a horizontal axis within the aquarium and has a large number of small holes in its peripheral wall, and contains water in the aquarium. This dry washing machine is designed to wash the items in the rotating drum by rotating the rotating drum.

[Problems to be Solved by the Invention] However, in the first type, the items to be washed are soaked in water in a water tank and are stirred by a stirring blade to be washed by a water stream. , A large amount of water is required when washing, and the washing action tends to cause the objects to be washed to become twisted or tangled. There have been cases where the balance has been disrupted and the spin-drying operation cannot be performed smoothly, making it impossible to perform the washing and spin-drying operations continuously.

In addition, in the second type, washing is performed by rotating a rotating drum around a horizontal axis and transferring the items to be washed without relying on water flow, so it is comparable to the first type. The amount of water used when washing is reduced, and the items to be washed are no longer twisted or tangled. However, in this second type, at the end of the washing operation, the object to be washed is unevenly distributed at the bottom of the rotating drum due to its own mu, causing the center of gravity of the rotating drum to become unbalanced. It was not possible to perform a dewatering operation by rotating the drum at high speed around a horizontal axis. For this reason, this type of washing machine that performs dehydration uses a large weight such as a flywheel to suppress vibrations. Therefore, this type of washing machine was heavy and unsuitable for household use.

This invention was made by focusing on the problems that exist in the conventional technology, and its purpose is to wash the items to be washed without causing twisting, entanglement, or fabric damage. To provide a dehydrating washing machine capable of sequentially and effectively performing rinsing and dehydration.

Furthermore, it is an object of the present invention to eliminate foam that overflows from an overflow port outside the overflow port for maintaining the water level of the water to be washed at a constant level when rinsing items to be washed; To provide a dehydrating washing machine capable of preventing bubbles from flowing back into a tank from its mouth and excellent in removing bubbles.

[Means for Solving the Problem] In order to achieve the above object, the dehydration washing machine of the present invention includes an outer tank, a support body rotatably supported around a vertical axis within the outer tank, An inner tank is rotatably supported on the support body around a horizontal axis or an inclined axis tilted at a predetermined angle with respect to the horizontal axis, and has a peripheral wall with a large number of small holes. a washing driving means for washing by rotating the inner tank around the horizontal axis or the inclined axis with water contained in the outer tank and items to be washed stored in the inner tank; a dewatering drive means for dewatering by rotating the support body integrally with the inner tank at high speed around the vertical axis while the items to be washed after being washed are housed therein; In addition to providing an overflow port, an expansion chamber for extinguishing foam that communicates with a drainage hose is provided on the outside of the overflow port, and a weir member is provided at the overflow port to prevent foam from flowing backward from the expansion chamber into the outer tank. In addition, a drainage channel is cut out in a part of the weir member.

[Function] In the dehydrating washing machine configured as described above, water is stored in the outer tank, and with the items to be washed stored in the inner tank, the inner tank rotates around the horizontal axis or the inclined axis. The washing machine is rotated by the machine to wash the items to be washed. Further, with the items to be washed stored in the inner tank, the support body is rotated at high speed around a vertical axis integrally with the inner tank to dehydrate the items to be washed.

Furthermore, in this dehydrating washing machine, when rinsing the items to be washed, the foam that overflows from the overflow port to the outside of the outer tank is temporarily stopped and eliminated in the expansion chamber before flowing into the drain hose, and the foam is removed from the expansion chamber. A weir member provided at the overflow port prevents bubbles from flowing back into the outer tank through the overflow port.

A dewatering operation based on the rotation of the inner tank 33 and a drying operation based on the a-air supply by the hot air supply device 104 and the rotation of the inner tank 33 by the first drive mechanism 79 are performed.

When the laundry is to be washed, the drain valve and clutch solenoid (not shown) are turned off, the spring clutch 74 is cut off, and the first drive @
At the same time as the mechanism 79 is formed, the brake body 78 is brought into a braking state and rotation of the inner tank 21 is regulated. In this state, the seed part driving motor 55 is rotated, the inner tub 33 is rotated around the horizontal axis XX through the first drive mechanism 79, and the items to be washed are rotated by the plurality of reversing prongs fIe38, 46. While being rolled, so-called washing by beating is performed.

Therefore, compared to a method in which the items to be washed are stirred with water using a pulsator, etc., fewer water lids are used during washing, and there is almost no twisting or entanglement of the items to be washed during the washing operation, so there is almost no damage to the fabric. It is possible to perform the washing motion effectively without causing any problems, and furthermore, there is no need for the troublesome work of correcting twists and entanglements of the items to be washed after the washing motion is completed, and the washing motion can be changed from the washing motion to the draining motion and the spin-drying motion. It can be automatically migrated.

Further, when rinsing is performed after washing the laundry, the inner tub 33 is rotated around the horizontal axis X-X by the sliding part movement motor 55 via the first drive mechanism 79, as in the case of washing. At the same time, by opening the water supply valve 84 of the water supply device 83, water is supplied from the first water supply port 85 toward the outer peripheral surface of the inner tank 33, and at the same time, water is supplied from the second water supply port 86 to the ventilation passage 99 and the ventilation port 101. and the inner tank 33 via the rear shaft part 34.
Water is supplied to the inside of the outer tank 15, and the rinsing water in the outer tank 15 is discharged from the drainage channel 100 of the overflow port 95, so that the water level is kept constant. Therefore, the rinsing water is replaced sequentially, and the bubbles adhering to the outer circumferential surface of the inner tank 33 are gently washed away along the spherical outer circumferential surface by the water from the first water supply port 85, and the bubbles in the inner tank 33 are gently washed away along the spherical outer circumferential surface. Bubbles attached to the items to be washed,
It is effectively washed away by water from the second water supply port 86.

Once the bubbles cross over the weir member 99 and enter the expansion chamber 96, the weir member 99 reliably prevents the bubbles from flowing back from the expansion chamber 96 into the outer tank 15. The foam that has entered the expansion chamber 96 is gradually discharged to the outside through the overflow hose 97 and the drain hose 89 together with the water that leaked into the overflow port 95.

Further, when dewatering is performed after the washing and rinsing of the laundry, the drain valve and the clutch solenoid are turned on, and the spring clutch 74 is connected to the second
At the same time as the driving armature 80 is formed, the brake body 78 is brought into a non-braking state and the rotation of the inner tank 21 is allowed. In this state, the sliding part movement motor 55 is rotated, and the second drive mechanism 8
0, the inner tank 21 and the inner tank 33 are integrally connected to the vertical axis Y-
It rotates at high speed around the Y to dehydrate the items to be washed. Therefore, the rotational axis of the inner tank 33 can be changed from the horizontal axis X-X to the vertical axis Y-Y without changing the attitude of the tank. By making changes, it can be done smoothly in a short time.

In addition, when drying is performed after dehydrating the items to be washed, the inner tank 33 is rotated around the horizontal axis X-X by the sliding part driving motor 55 via the first driver m79, as in the case of washing. At the same time, when the fan motor 106 and the heating heater 111 are energized, the warm air generated from the hot air supply device 104 is transmitted to the visible bellows-shaped connecting cylinder 11.
3. Ventilation vent N112. The air is supplied into the inner tank 33 via the air outlet 114 and the rear shaft portion 34 . Therefore, as the inner tank 33 rotates, the items to be washed are transferred and the drying operation is performed.

During this drying operation, the high-temperature and humid air in the inner tank 33 is transferred to the rear shaft portion 34 of the inner tank 33, which also serves as an air outlet.
Water is discharged into the overflow hose 97 from an overflow port 95 formed in the side wall of the outer tank 15 on the opposite side, which also serves as a hot air exhaust port, and the expansion cooling chamber 9 including the overflow hose 97
8 and the drain hose 89 are effectively cooled by the airflow generated by the motor cooling fan 102, so that the hot and humid air passing through the hoses 89, 97 and the expansion cooling chamber 98 is cooled and dehumidified. Drain hose 89
is discharged to the outside through the Therefore, the hot and humid air inside the inner tank 33 is rarely discharged to the outside as it is.

[Effect of the invention] Since this invention is configured as explained above,
It has the following effects.

The support body is rotatably supported within the outer tank about a vertical axis, and the inner tank is supported rotatably about a horizontal axis or an inclined axis within the support body, without changing the attitude of the support body. Since it is configured to use the rotation axes of the support body and the inner tank to perform washing, rinsing, and dewatering operations, each operation can be performed in sequence without changing the attitude of the tank. These operations can be performed continuously in a short period of time.

Furthermore, in each washing and dewatering operation, the inner tank containing the items to be washed is first rotated around a horizontal axis or an inclined axis, so that the items to be washed can be washed without using swirling water flow. Because of this, less water is used during washing, and since there is almost no twisting or entanglement of the items to be washed during the washing operation, the washing operation can be carried out effectively with almost no staining of the cloth. After the washing operation is finished, there is no need for the troublesome work of correcting twists and entanglements of the items to be washed, and the washing operation can automatically shift to the dehydration operation.

Moreover, an expansion chamber is provided outside the overflow port for extinguishing foam, and a U member with a drainage channel is provided at the overflow port, so that when rinsing items to be washed, the foam that overflows from the overflow port is removed. , it can be temporarily held in the expansion chamber before flowing into the drainage hose, and can be easily erased.
The weir member can reliably prevent bubbles from flowing back into the tank from the overflow port, and the rinsing process can be performed without bubbles, and the structure is simple.
