Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine for washing clothes contained in a washing tub.

[0002]

2. Description of the Related Art Conventionally, this type of washing machine has been constructed as shown in FIG. The configuration will be described below.

As shown in FIG. 40, a washing tub 71 accommodates clothes 72 therein and supplies water or washing water from a water supply path 73 to wash a stirring blade 74 arranged at the inner bottom of the washing tub 71. A rotation drive unit 75 provided below the tub 71 is configured to be driven through the speed reducer 76 for washing. A drain hose 77 and the like are arranged on the outer wall of the washing tub 71, and after the washing process is completed, the drain hose 77 is tilted to drain the water. In this way, the washing tank 71, the rotation drive unit 75, the drain hose 77, etc. are integrally configured.

[0004]

In the conventional structure as described above, in order to perform washing, the washing machine itself must be transported to the place where the water supply means or the place where the drainage means is provided together with the drive unit. In addition, when the clothes after washing are transferred to a general washing machine or the like, it is necessary to transfer them to another container such as a bucket.

Further, the recent trend of household washing machines is shifting from a two-tub type washing machine to a fully automatic washing machine, and further, popular type washing machines have various washing functions. However, the washing machine has become versatile, and clothes that are hygienic such as underwear and towels, as well as soiled items such as rags and socks must be washed in the same washing machine. From the viewpoint of hygiene, there is an increasing demand for a washing machine that can easily wash only heavily soiled items before washing.

[0006] In addition, due to the recent trend toward cleanliness, clothes are not as dirty as they used to be, and as a whole, clothes that are not so dirty are increasing. However, clothes that are extremely dirty, such as children's socks, still exist,
Although the amount is small, there is still a strong need to wash it thoroughly. It is possible to wash with a large-sized washing machine, but because it is large, it consumes a large amount of water and detergent,
The number of washings will also increase. Therefore, it has been awaited to develop a washing machine which can be easily washed with only a dirty one and is easy to use.

Furthermore, due to the recent housing situation, even in the storage place, even if the washing machine is as small as the former washing machine, it takes a space to store the washing machine. For this reason, it is necessary to develop a washing machine with excellent storability.

Further, with the recent diversification of clothes, particularly in women's underwear, the number of delicate clothes which are deformed and discolored when collectively washed with a fully automatic washing machine is increasing. For this reason, despite the evolution of washing machines, appliances such as buckets and tarais that are used as simple washing means still exist in homes, and people often wash clothes by hand. In addition to delicate items, buckets are also used for bleaching and gluing cutter shirts, pet clothes and wipes, and car washing, and in the washing process, washing water may touch the hands and cause rough hands.

The present invention solves the above-mentioned conventional problems. The washing tub and the driving side base are separated so that they can be removably attached to facilitate the handling, and to prepare for washing and after-washing. The purpose is to improve operability such as processing.

[0010]

In order to achieve the above-mentioned object, the present invention is detachably mountable on a drive-side base having a rotary drive installed therein and on the upper surface of the drive-side base with an upper opening. The washing tub is composed of a stirring wing that rotatably stirs clothes on the inner bottom, the stirring wing is attached to the upper end of the shaft that penetrates the bottom of the washing tub, and the lower end of the shaft. The first transmission joint that transmits the rotational drive is attached, and the drive side base is
When the second transmission joint that rotates in connection with the rotation drive device is provided on the upper surface and the washing tank is mounted on the upper surface of the drive-side base, the first transmission joint and the second transmission joint are coupled and the drive is performed. The side base is held by the holding projections on the inner wall of the washing tank.
It is configured so that it can be stored in the washing tank.

As a result, the washing tub and the drive-side base can be separated and detachably mounted to facilitate the handling and improve the operability such as preparation for washing and subsequent processing. it can.
