Sterilizing Laundry Safely with Optical Plasma Technology
Here’s PatSnap Eureka !
Summary
Problems
Existing laundry treatment apparatuses face challenges in effectively sterilizing laundry without damaging temperature-sensitive materials and while minimizing harmful effects on humans, as methods like ultraviolet rays, silver ions, and ozone can be hazardous.
Innovation solutions
A laundry treatment apparatus incorporating an optical plasma generation unit with an air chamber, where external air is irradiated by a photoplasma tube to create a sterilizing gas that is circulated and blown into the laundry treatment barrel, utilizing UVC and UVD ultraviolet bands to efficiently sterilize without high temperatures or harmful byproducts.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If garments are tumbled in a conventional dryer, then drying is achieved, but wrinkles and distortion are created
Why choose this principle:
The drying process is segmented into multiple zones within the tumble dryer: a suspension zone where garments are lifted and suspended, and a separation zone where garments are deposited. This segmentation allows garments to be dried without excessive tumbling contact, reducing wrinkles while maintaining drying effectiveness.
Principle concept:
If garments are tumbled in a conventional dryer, then drying is achieved, but wrinkles and distortion are created
Why choose this principle:
The dryer uses dynamic control of the tumble motion, varying the drum rotation speed and direction to create optimal suspension and deposition cycles. The dynamic adjustment of tumbling intensity allows garments to be suspended in mid-air during critical drying phases, minimizing contact-induced wrinkles.

Abstract
A laundry treatment apparatus in the present application includes a laundry treatment barrel and a light plasma generation unit having an air chamber. The air chamber is internally provided with a photoplasma tube for irradiating air in the air chamber. An air inlet of the air chamber is in communication with the external air; and an air outlet of the air chamber is in communication with an interior of the laundry treatment barrel via an air outlet pipeline. In the present application, the external air in the air chamber irradiated by the photoplasma tube is generated a sterilizing gas which is blown into the laundry treatment barrel via the air outlet pipeline, thereby sterilizing and deodorizing the interior of the laundry treatment barrel and laundry inside to completely kill microorganisms and efficiently remove unpleasant odors, especially a sterilizing effect is better for laundry being no-resistant to high temperature.
