Description

Portable Washing Machine {PORTABLE WASHING MACHINE}

According to the present invention, the outer casing and the outer tub of the washing machine are integrally manufactured to reduce the size of the washing machine and reduce the weight of the washing machine, and to wash and dry the laundry as well as the inner tank (washing tank). It relates to a compact / lightweight portable washing machine which is almost free and which can be easily transported from one place to another.

Generally, a washing machine includes: an outer casing having various components described later; An outer tank in which washing water is stored; A washing tank for putting laundry; A driving unit for driving a washing tank; A water supply port and a drain port provided with an automatic opening / closing valve; It is composed of a control unit for controlling the operation of the drive unit and the automatic opening and closing valve according to the content of the recorded program. In particular, in the case of a drum washing machine, the washing tank settled in the outer tank rotates horizontally on the ground.

Here, "horizontal direction" means that the axis of rotation of the washing tank is horizontal to the ground.

However, such a conventional washing machine has a heavy disadvantage since the outer casing, the outer tub, and the washing machine have a triple overlapping structure.

In addition, since a conventional washing machine has a structure in which a rotating shaft of a driving motor is directly connected to a rotating shaft core of a washing tub or a driving motor is installed at a predetermined distance away from the rotating shaft core, the driving shaft is connected between the rotating shaft and the rotating shaft core by a belt or the like. A large inner space is required between the outer casing and the outer tub, and therefore, a washing machine has to be enlarged.

In addition, the conventional washing machine has a disadvantage in that the rubber packing should be sealed to the rotating shaft portion of the drive motor to which electricity is input in order to prevent an electric shock accident.

In addition, the conventional washing machine has a high probability of failure due to the large number of assembly parts, and thus has a disadvantage in that it takes a lot of time to disassemble the assembly parts during repair / repair due to the failure.

For this reason, there has been a demand for a compact portable washing machine for easy maintenance and a small amount of laundry.

On the other hand, in response to this demand, a casing with a built-in motor; A laundry container detachably assembled to the upper casing; A rotary blade driven by the motor and rotating at the inner bottom of the laundry tub; Many small washing machines have been developed that consist of a cover that covers the top of a laundry tub.

However, the above-mentioned conventional compact washing machines are only three-dimensional structure with a casing, an outer tub, and a washing tub, only to reduce the external volume, and thus do not solve any problems of the conventional large washing machines.

On the other hand, a small washing machine other than the conventional small washing machine described above, the casing having a water tank therein; A door coupled to the casing to open and close the opening; A laundry drum rotatably received in the water tank and having a plurality of through holes and laundry input doors formed on an outer wall thereof; A small washing machine composed of driving means for driving the washing drum has been proposed (Korean Patent Publication No. 1999-73967).

However, the small washing machine is a small / light weight by excluding some of the functions of the large washing machine has only a basic cold water washing function and dehydration function, so the laundry that requires washing, for example, underwear, especially cleaning is required There is a drawback that washing is not possible. In addition, the washing machine does not have a drying function can not dry the laundry to be used in a hurry to wash, and therefore, the laundry was put on a drying rack to dry or ironed to dry.

As described above, conventional large washing machines and small washing machines have disadvantages, and therefore, a new type of small washing machine capable of satisfying both the versatility of the large washing machine and the portability of the small washing machine is required. For example, the low electricity consumption means that there is no cost even if a small amount of washing is frequent, and it is easy to carry when the user changes the place of residence, easy to repair / repair, and portable from laundry to laundry drying at once. A washing machine is required.

The present invention has been made to overcome the above-mentioned problems, and an object of the present invention is to provide a compact / lightweight portable washing machine having a washing function and a rinsing function as well as a dehydration function, a washing function, and a laundry drying function.
