Description

[0001] Pushing device of wash [

[0001] The present invention relates to a laundry pressing apparatus, and more particularly, to a laundry pressing apparatus which reduces the volume of laundry by pressing laundry contained in the washing tub, thereby preventing waste of water unnecessarily wasted and discharging laundry to the upper side of the washing tub So that the laundry can be prevented.

Generally, when a large amount of laundry is to be washed, a washing machine is used, in which the washing machine is rotated by the power of the motor. In such a washing machine, a washing machine and a motor for rotating the washing machine are provided. In general, the washing tub is provided with a plurality of holes for allowing wash water to escape to the water storage tank side.

The washing machine currently used is divided into an agitating type washing machine, a swirl type washing machine, and a drum type washing machine according to the washing type. In the swirl type washing machine, a pulsator mounted rotatably on the lower end of the washing tub is rotated to generate a swirling water flow Which is one of the most widely used methods of rotating laundry together with washing water.

The drum type washing machine has a cylindrical drum having a plurality of water passages formed therein, which is horizontally rotatably mounted in a water reservoir. The laundry is rotated by the protrusions in the drum to raise the laundry into the space above the drum, They are designed to be washed while falling, and are suitable for large-capacity laundry.

In addition, in the stirring type washing machine, when the washing rod rotatably mounted at the center of the washing tub is rotated regularly, the stirring blade formed on the side of the washing rod stirs the washing water stored in the washing tub to form a water flow, The laundry is floated in the washing water while rubbing against the stirring blade of the washing bar and the wall of the washing tub, thereby washing the laundry.

Such a stirring type washing machine has a drawback that the laundry is less tangled than the swirl type washing machine, the washing capacity is large, but the power consumption is large and the friction area due to the rotation of the washing rod is large, have.

On the other hand, when the laundry is washed using a washing machine, when the volume is relatively large such as a large jamb or a bed, the washing machine occupies the whole of the washing tub. Therefore, when the washing machine supplies the excessive washing water by the laundry, The water of the laundry is wasted unnecessarily.

Further, in the course of washing the laundry while being rotated or spinning at a high speed, the laundry often flows out to the upper side of the washing tub, resulting in damage to the laundry.

In addition, since the laundry floats on the water surface, that is, the washing water due to the buoyancy of the laundry, the laundry is not easily immersed in the washing water. When the laundry is washed up on the washing water, There is a problem that it is not properly performed.

Accordingly, there is a demand for a pressing device for pressing the laundry placed in the inside of the washing tub to reduce the volume and prevent the laundry from escaping.

A conventional laundry pressing apparatus for a washing machine is disclosed in Japanese Patent No. 10-1437466, which comprises a base, a plurality of wings having one side formed on the outer circumferential surface of the base and the other side engaged with the inside of the washing machine, And at least one elastic member having one side connected to the support unit and the other side connected to the inside of the washing machine.

Such conventional technology prevents unnecessary waste of water, that is, washing water, by pushing the upper portion of laundry laid inside the washing tub.

However, in the conventional art, a plurality of wings are positioned on the upper side of the washing tub, and the laundry is pressed by the structure that the hook provided at the end of the elastic member is hooked to the upper side of the washing tub Since a plurality of wings are located on the upper side of the washing tub, it is impossible to reduce the volume of the laundry because a plurality of blades for pressing the laundry into the washing tub can not enter.

That is, in order to minimize the volume of the laundry laid inside the washing tub, the pressing device must be inserted into the washing tub. However, since the hook is fixed to the upper side of the washing tub in the prior art, It is not possible to reduce the volume of the laundry laid inside the washing tub even if it is prevented to some extent.
