DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine in which an inner tub is rotatably supported around a vertical axis inside an outer tub, so that laundry in the inner tub can be washed, dehydrated and dried. It is about the machine.

[0002]

2. Description of the Related Art In a spiral type washing machine, which is mainly used in Japan, washing is poured into an inner tub, washing water is poured, and the inner tub is rotated around a vertical axis.
The laundry in the inner tub is subjected to rubbing-based washing, and then rinsed. Thereafter, the inner tank is rotated at a high speed to drain water from a number of holes formed in the wall surface of the inner tank to perform dehydration. Finally, warm air is blown into the inner tub to dry the laundry.

[0003] On the other hand, in a stirring type washing machine widely used in the United States, the inner tub is rotated in small steps forward and reverse around a vertical axis, and the laundry in the inner tub is basically washed with a massage. Apply laundry.

[0004] In a drum-type washing machine mainly used in Europe, the inner tub is driven to rotate about a horizontal axis, and the laundry in the inner tub is washed by slap-washing. Apply.

[0005]

According to the spiral type washing machine and the stirring type washing machine, a high washing effect can be obtained, but the laundry is greatly damaged and the amount of washing water and detergent used is large. There is. On the other hand, in a drum type washing machine,
Although the laundry receives less damage and uses less washing water and detergent, there is a problem that the inner tub vibrates greatly during dehydration.
Further, in any of the washing machines, there is a problem that the laundry is wrinkled or out of shape in the process of performing the dehydration and drying.

Accordingly, an object of the present invention is to provide a low-vibration type washing machine in which the inner tub is rotated about a vertical axis, the damage to the laundry is extremely small, and the amount of washing water and detergent used is small. Another object of the present invention is to provide a new type of washing machine in which almost no wrinkles or out of shape are generated in the laundry.

[0007]

A washing machine according to the present invention comprises an outer tub (2), and an inner tub (3) supported inside the outer tub (2) so as to be rotatable around a vertical axis. It has a warm air mechanism for blowing warm air into the inside of the inner tank (3). Further, a hanger (5) for hanging laundry is installed inside the inner tub (3) so as to be able to move up and down and rotate integrally with the inner tub (3). Specifically, a rotation drive mechanism is connected to the inner tank (3), and a lifting drive mechanism is connected to the hanger (5).

In the above washing machine, a washing mode by raising and lowering the hanger (5), a dehydration mode by rotating the inner tub (3) and the hanger (5), and a drying mode by operation of the hot air mechanism can be set. It is. That is, in the washing mode, the laundry is hung on the hanger (5) in the inner tub (3), and a relatively small amount of washing water and detergent are poured into the inner tub (3). Operate to move the hanger (5) up and down. Here, if the lifting / lowering range of the hanger (5) is set in the washing water in the inner tub (3), the laundry moves up and down in the washing water, and rubbing is performed. Also, by rapidly lowering the hanger (5) into the water from a position above the water surface of the washing water, the laundry is slammed against the water surface, and the washing is performed. Furthermore, by lowering the hanger (5) to the bottom of the inner tub (3) and pressing the laundry against the bottom of the inner tub by the hanger (5), the laundry can be subjected to push washing.

In the dehydration mode, after the washing water in the inner tub (3) is drained, the rotation drive mechanism is operated to rotate the inner tub (3).
At high speed. With the rotation of the inner tub (3), the hanger (5) rotates at high speed together with the laundry. Due to the centrifugal force at this time, washing water is discharged from the laundry hung on the hanger (5), and the washing water flows from the inner tub (3) to the outer tub.
It is discharged outside through (2).

[0010] Thereafter, in the drying mode, the warm air mechanism is operated to blow warm air to the laundry hanging on the hanger (5). Thereby, the laundry is dried. Here, if the inner tub (3) and the hanger (5) are rotated as needed, warm air can be blown to the corners of the laundry, thereby improving the drying efficiency.

In a specific configuration, the hanger (5) is installed at the center of the inner tank (3) and is supported by a support member (6) to be connected to the lifting / lowering drive mechanism, and extends radially from the support member (6). It has a plurality of hanger arms (51) and is detachable from the inner tank (3). According to the specific configuration, the hanger
With (5) removed from the inner tub (3), laundry can be hung on each hanger arm (51). Then, the hanger (5) is installed in the inner tank (3), and the support member (6) is connected to the lifting drive mechanism. Thereby, the support member (6) can be moved up and down. Since the laundry is hung on each hanger arm (51), a constant interval is maintained between the laundry, so that in the process of washing, dehydrating and drying, the laundry does not become entangled with each other. Thus, these processes are effectively executed.

In a specific configuration, each hanger arm (51) has a base end detachably engaged with the support member (6) and a tip end formed on the inner peripheral wall of the inner tank (3). Slidably engaged with the vertical arm guide (31), the base end of each hanger arm (51) is separated from the support member (6) by the hanger (5), and each hanger arm (51) An arm rotating mechanism for rotating the arm to a position along the inner peripheral wall of the inner tank (3) is connected.

According to this specific configuration, when the spin-drying mode is set, the arm rotation mechanism is operated to set each hanger arm (5).
The base end of (1) is separated from the support member (6), and each hanger arm (51) is rotated to a position along the inner peripheral wall of the inner tank (3). Thereby, the laundry hung on each hanger arm (51) is hung along the inner peripheral wall of the inner tub (3). In this state, if the inner tub (3) and the hanger (5) are rotated at a high speed, the laundry is centrifugally received while being spread along the hanger arm (51), and the inner periphery of the inner tub (3) is received. It adheres to the surface and is dehydrated by centrifugal force. Therefore, the laundry does not wrinkle or lose its shape.

More specifically, the arm rotating mechanism moves each hanger arm (51) from the set position where the hanger arm (51) is engaged with the support member (6) to the inner tub with the shift from the washing mode to the spin-drying mode.
Rotate to the deployed position along the inner peripheral wall of (3) and move each hanger arm (5
It has a rotation control mechanism for rotating 1) from the deployed position to the collection position.

According to the specific configuration, the arm rotation mechanism is automatically operated in accordance with the mode transition, and each hanger arm (between the gathering position in the washing mode and the drying mode and the unfolding position in the dehydrating mode is moved. 51) can be moved back and forth.

[0016]

According to the washing machine of the present invention, in the washing mode, the laundry can be moved up and down to perform the washing by rubbing, slap washing or push washing.
Compared to a spiral-type washing machine or a stirring-type washing machine, the damage to the laundry is small and the amount of washing water and detergent used is small. Of course, the laundry is subjected to dehydration and drying while being hung on a hanger, so that the laundry has almost no wrinkles or out of shape.
