Integrated ozone generator for washing machine {INTEGRAL SHAPE OZONE GENERATOR FOR WASHING MACHINE}

The present invention relates to a washing machine, and more particularly, to an integrated ozone generator for a washing machine incorporating an air bubble generator and an ozone generator.

Most washing machines use the pulsator's mechanical strength and the surface activity of chemical detergents to wash the laundry.

This improves the ability of the pulsator to agitate the laundry to improve the washing effect, or extends the operating time and water flow time of the motor, and in addition improves the quality of the detergent used in the washing machine or increases the amount of the detergent. You have to.

However, there is a limit to increase the washing efficiency by the above method for the following reasons.

In other words, the method of using the increased mechanical force to improve the washing efficiency damages the laundry, the method of using the increased amount of detergent discharges a large amount of detergent that does not react with the laundry, causing environmental pollution Detergents stick to the laundry to prevent the laundry from being washed effectively.

On the other hand, U.S. Patent No. 5,653,129, issued to Aug. 5, 1997, discloses an air bubble washing machine having an air bubble generator and an ozone generator connected in parallel.

Ozone (O ₃ ) is a three-atomic allotrope of oxygen, while a typical oxygen molecule (O ₂ ) has two oxygen atoms, while the ozone molecule consists of three oxygen atoms.

Such ozone can be generated by passing air or oxygen through a high intensity electric field, and some of the oxygen molecules are energized and separated into two individual atoms. These individual oxygen atoms will then weakly bond with other oxygen atoms.

The ozone molecule is highly reactive oxygen, and the ozone molecule tends to discard its extra oxygen atoms to obtain electrons. This molecular structure gives ozone a high oxidizing power so that ozone can react quickly with various compounds.

Ozone is a well-known second strong oxidizer and thus is used in the beverage and water treatment industries, and because of this fact, ozone is widely used in the control, odor removal, and laundry industries of contaminants such as microbial fungicides.

The main role of the ozone is to remove the dirt from the fabric by the positive action in the laundry process, ozone also dissolves and rapidly precipitates the oxidation.

In addition, ozone has the strongest gaseous form in the washing process and reacts rapidly with the dirt to remove the dirt, thus reducing the washing time, and for this reason, 1/2 ozone of the amount of surfactant commonly used is Excellent results can be obtained by using.
