In more detail, a washing tank for storing the washing water is provided, and a predetermined amount of washing water is stored in the washing tank according to the washing amount, and the laundry is put in the washing water to wash the water.

However, the laundry is washed depending on the flow of simple washing water, and the washing effect is poor. Especially, the laundry which has been chemically processed or the oil-containing laundry does not have the desired washing effect. Various chemical detergents have been developed and these chemical detergents are put into the washing process to enhance the washing effect.

However, although the effect of washing was obtained by adding a chemical detergent, a separate rinsing process was added to treat post-treatment, that is, the foam of the detergent, which causes a long washing time and thus poor workability. There was a defect that the consumption of the washing water is increased by the rinsing process.

Thus, separate and de-removable devices are installed in the washing machine for foaming of detergents.

For example, the upper part of the washing tank installed in the washing machine covers the upper surface of the tank as a whole, and at the same time detachably installs a sprinkling plate having a plurality of spraying holes over the entire surface thereof, and the washing water is entirely installed in the tank through the sprinkling plate thereof. They are evenly discharged and sprayed to wash away the foam of the detergent from the laundry.

In other words, after washing, the wash water in the tank is completely drained, and when the drainage is completed, the de-washed product suspended in the wash water descends in accordance with the water flow of the wash water drainage, penetrates into the wash or remains on the surface, and in this state Although the washing water is dropped to the inside of the tank to wash out the foam, the bubble-washed product is filtered out and only a part of it is discharged with the washing water. Water was consumed unnecessarily for a lot.

In addition, foreign matters that float out of the laundry during the washing operation, that is, lint, are collected by the foreign matter collection means installed separately at a predetermined position in the tank, and the foreign matters that are suspended in the washing water are collected and filtered. There was a problem that lint remaining in the wash water when the drainage after the rinsing process is stuck to the laundry to remove it.

The present invention has been made in consideration of the above circumstances, and an object thereof is to separate and process the foam of the detergent suspended in the upper part of the wash water with the wash water at the water level, so that the washing machine has excellent washing property and reduces the rinsing process. The present invention provides a defoamer and a method thereof.

Another object of the present invention is to provide an apparatus and a method for removing a washing product of a washing machine having a washing effect by collecting foreign substances suspended on the surface of the washing water after the washing process and simultaneously collecting the washing product.

That is, according to the present invention, at a predetermined position of the washing tank, that is, at the same position as the low water level of the washing water or slightly higher than the water level, the foam of the chemical detergent generated during washing is drawn out to the outside and driven according to the control signal of the washing process. An outflow part is opened and closed by a defoaming valve, and the outflow part is provided with a suction power by a blowing force of a fan driven by a control signal of an outflow part, a closing operation or a washing process. It is installed with a suction means for forcibly drawing out the product removed.
