DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a washing / dehydrating tub provided in a body of a fully automatic washing machine for home use, for example.

[0002]

2. Description of the Related Art In recent years, as a so-called home washing machine for washing several kilograms of laundry, all operations of washing, rinsing, and dehydrating the laundry (in a washing / drying tub provided inside the body) ( A fully automatic washing machine in which the “washing and dewatering operation” is performed under the control of a computer program is mainly used. An outline of the configuration of an example of such a washing machine will be described with reference to FIGS. 3 and 4A.

Outside the washing machine S (mainly, see FIG. 3), a rectangular parallelepiped body 1 has a lid 2,
An operation panel 3, a water supply port 4a, and the like are provided, and a drain hose 4b, a power plug 5, and the like are provided on side surfaces thereof. here,
The lid 2 is a body 1 that communicates with a washing / dewatering tub 10 described later.
And an inner lid 2b that opens and closes an opening 13 of the washing / dehydrating tub 10, which will be described later. The operation panel 3 selects a washing / dehydrating operation program built in the computer by the operation. The water supply port 4a is for introducing water into a washing / dewatering tub 10, which will be described later.
Is for discharging water from an outer tank 30 described later.
Further, the power cord 5 supplies power to a drive motor 40 described later.

The inside of the washing machine S (mainly in FIG. 4)
(See (a)), the washing / dewatering tub 10, the pulsator 20, the outer tub 3
0, a drive motor 40, and the like.

[0005] The washing / dewatering tub 10 is used for washing and dehydrating operations by putting laundry therein, and is made of a hard rustproof material such as stainless steel, plastic, resin or the like, and has a hollow outer peripheral cylinder 11. The bottom disk 12 is integrally formed at one end, and an opening 13 opening upward is formed at the other end. A number of holes (not shown) for draining water during centrifugal dehydration are formed in the side of the outer peripheral cylinder 11, and unnecessary swings during rotation of the washing / dehydrating tub 10 are removed above the holes. The balance ring 14 is provided in an annular shape. The outer peripheral cylinder 11
An overhanging portion 15 such as a lint-removing net and a detergent charging portion is formed on the inner peripheral side portion of the device.

The pulsator 20 is a stirring blade for generating a water flow in the washing / dewatering tub 10, and is rotatably provided on the bottom disk 12 of the washing / dewatering tub 10.
The outer tub 30 is a basket that receives water during the washing / dewatering operation, and is provided so as to cover the outer periphery of the washing / dewatering tub 10. Further, the drive motor 40 drives the pulsator 20 during washing and rinsing, and the washing and dewatering tub 10 during dehydration.
Are respectively rotated, and are provided below the outer tub 30. The rotating shaft 41 transmits the rotating force of the driving motor 40 to the pulsator 20 and the washing / dewatering tub 10.

[0007] Each of the above structures is not particularly different from the structure generally used in the conventional washing machine S. Among the above configurations, the characteristic configuration related to the washing / dehydrating tub according to the present invention will be described later in detail.

[0008] The procedure of the washing and dehydrating operation by the washing machine S having such a configuration is as follows (see FIGS. 3 and 4). (1) The worker M opens the lid 2 and sets the
Put laundry and detergent into the inside, and close the lid 2. (2) The worker M operates the operation panel 3 to select an arbitrary program from the washing / dehydrating operation program built in the computer. (3) The washing and dewatering operation is performed by the operation of the washing and dewatering tub 10 of the washing machine S in a fully automatic order of washing, rinsing and dehydrating. (4) The worker M opens the lid 2 and sets the
Take out the dehydrated laundry below.

That is, the “washing / dehydrating operation” in the above procedure (3)
Is automatically performed by the operation of the washing / dewatering tub 10 of the washing machine S, and the above procedure (1), (2), and (4) is performed by the worker M.
Is very convenient.
The above procedures are not particularly different from the procedures generally performed in the conventional washing machine S.

[0010]

However, even in the case of the fully automatic washing machine S, the above-mentioned procedure (4) "removal of the laundry", that is, after the dehydration in the lower part of the washing / dehydrating tub 10, It is necessary for the worker M to take out the laundry by pulling it up by hand. On the other hand, in the ordinary washing machine S, the height of the body 1 is formed low to achieve compactness and space saving, and the depth of the washing / dehydrating tub 10 is increased to increase the capacity of washing / dehydrating. Often formed. Therefore, as shown in FIG. 4B, the lower part of the washing / dewatering tub 10 where the dehydrated laundry is located, that is, the bottom of the washing / dewatering tub 10, is located at the position of a normal worker M such as a housewife at home. It will be located around the knee.

When the washing / dewatering tub 10 and the worker M are in such a positional relationship, the worker M cannot reach the bottom of the washing / dewatering tub 10 while standing, -Since it is not possible to take out the laundry under the dehydration tub 10, it is necessary to perform the "removal of the laundry" of the above-mentioned procedure (4) in a posture where the waist is necessarily bent.
As described above, the work in the posture in which the worker M is bent is not an easy work.
In the case of a short person, an elderly person, or the like, the operation is a hard work for the worker M.

Further, even if the worker M can reach the laundry below the washing / dehydrating tub 10 in a posture in which his / her hips are bent, the laundry after dehydration contains some moisture. Therefore, it was not easy to pull it up, take it out, and replace it with a transport basket. In particular, when the capacity of the washing / dewatering tub 10 is increased, such a problem is conspicuous, which has been a difficult task for the worker M.

[0013] Accordingly, it has been desired to provide a washing / dewatering tub in a washing machine so that the worker M can easily take out laundry in a standing posture, not a posture of bending his / her hips.

[0014]

In order to solve the above-mentioned problems,
The present invention is based on the premise that the washing / dehydrating tub is provided inside the body of the washing machine and opens upward. First, as shown in claim 1 (for example, see FIG. 1), A washing / dehydrating tub "characterized by comprising an elevating mechanism for raising and lowering the bottom of the water tub. According to this, it is possible to raise the bottom of the washing / dehydrating tub where the laundry after dehydration is located to a desired height position,
The worker M can easily take out the laundry while standing up.

Further, claim 2 (for example, see FIG. 2A)
As shown in, "The washing and dehydration tub can be moved up and down,
A washing / dehydrating tub, comprising a lifting mechanism. According to this, the laundry / dehydration tub itself with the laundry after dehydration can be raised to a desired height position, so that the worker M can easily take out the laundry in a standing posture. be able to.

Further, as shown in claim 3 (see, for example, FIG. 2 (b)), "the washing / dehydrating tub is provided with an elevating mechanism, and the washing / dehydrating tub is provided with the machine body. And a washing / dehydrating tub "characterized by being detachably attached to the washing machine. According to this, the laundry / dehydration tub itself with the laundry after dehydration can be raised to a desired height position, and the laundry / dehydration tub itself can be removed from the machine body. The laundry can be transported together with the washing / dehydrating tub without taking out the laundry.

[0017]
