Description

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 circulating water is circulated from the outer circumference of a rotary wing storage portion formed on the inner bottom of a washing tub.

[0002]

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

As shown in the figure, the washing tub 1 has a concave portion 2 formed in a part of its inner periphery, and the concave portion 2 is connected to a fan-shaped outlet 4 of a rotary blade housing portion 3. A discharge cover 5 and a water supply cover 6 are fitted in the recess 2 to form a passage 7 for blocking the inside of the washing tub 1. The discharge part 8 is provided above the water supply cover 6.
A filter 9 for collecting thread waste and the like is detachably attached to the discharge portion 8.

Such a structure is mainly used in a two-tub type washing machine, etc., and the water is pushed up into the passage 7 by the rotating force of the rotary blades 10 and is poured into the washing tub 1 from the filter 9 for washing. The liquid was circulating.

As shown in FIG. 11, the washing tub 1 is formed in a rectangular shape, and the above-mentioned washing liquid circulating device is provided at the corner of the washing tub 1. This is because it is possible to easily form the outwardly bulged passage 7 in the corner portion.
This is because the gap between the main body of the washing machine and the washing tub 1 is larger in the corner portion, and the passage 7 can be easily secured.

[0006]

In such a conventional structure, since the recess 7 is formed from the side wall of the washing tub 1 to the inner bottom, the shape of the washing tub 1 is easily deformed, and the washing tub 1 is particularly operated in hot water. At the time, there was a problem that deformation was likely to occur. Further, even when the same washing tub 1 is used to construct a product having no filter 8, the discharge cover 5 and the water supply cover 6 are required, and the shape and configuration are difficult to reduce in cost.

In addition, in order to provide the filter 9 at two or more places, when the specification is to provide a plurality of discharge parts 8 on the upper part of the washing tub 1, the recess 2, the discharge port 4, the discharge cover 5, the water supply cover 6 and the like are provided. Since the structure of the washing tub 1 must be provided in other parts, the structure is not only complicated, but also the strength is weakened, and the recess 2 expands due to water pressure and the water supply cover 6 and the like are easily removed. Had.

Further, in order to enhance the washing ability of the washing machine, it is essential to draw out the power of the detergent quickly,
For that purpose, not only the mechanical force but also water and detergent are circulated and dropped into the washing tub 1 from above so that the solution can be dissolved more quickly. Therefore, it is desired to provide a plurality of discharge parts 8 to increase the amount of circulating water and quickly dissolve the detergent. In addition, it is necessary to efficiently collect lint generated during washing in order to prevent the waste from adhering to the laundry, and a forced circulation type recovery mechanism is required. To this end, the plurality of discharge units 8 are attached to the washing tub 1.
It is necessary to form it on the upper part, and it is desired to easily and inexpensively construct it.

The present invention solves the above problems by sending circulating water from one discharge port at the bottom of a washing tub to a plurality of discharges at the upper part of the washing tub to quickly dissolve the detergent and enhance the cleaning effect. Its purpose is to collect lint or to add various functions such as a waterfall shower.

[0010]

In the washing machine of the present invention, a discharge port portion having one end side communicating with the pump chamber including the back blade of the rotary blade is provided, and the other end side of the discharge port portion is discharged into a plurality of discharges. It connects to the water channel, and the other end side of this discharge water channel is led to the upper part in the washing tub.

By this, circulating water is sent from one discharge port at the bottom of the washing tub to a plurality of discharges at the upper part of the washing tub, the detergent is quickly dissolved to enhance the cleaning effect, and further, lint waste is collected or falls. Various functions can be added to the shower.
