Steam Drum Laundry Control for Allergen Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry machines are inefficient in removing allergens such as house dust mites, animal hair, and pollens from laundry, which can exacerbate atopic dermatitis, and existing methods require excessive energy and time to achieve effective sterilization.
Innovation Solution
A laundry machine controlling method that uses steam to create a hot environment above 55°C for a predetermined duration to kill allergens, combined with rinsing and spin-drying steps, utilizing steam's higher heat capacity and direct heat transfer for efficient allergen removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If conventional hot water washing is used to remove allergens, then washing function is provided, but energy consumption is excessive and processing time is long
Solution Approach 1:
The patent utilizes the phase transition of water from liquid to steam to generate high-temperature steam for allergen removal. The steam generator heats water to produce steam at temperatures above 100°C, which then contacts the laundry to kill allergens efficiently, reducing both energy consumption and processing time compared to conventional hot water washing.
Solution Approach 2:
The patent changes the temperature parameter by using steam at temperatures above 100°C instead of conventional hot water at lower temperatures. This parameter change enables faster and more efficient allergen removal, as the higher temperature steam can kill mites and remove allergens more quickly than hot water washing.
2Productivity
If conventional hot water washing is used for allergen removal, then washing is performed, but processing time is excessive
Solution Approach 1:
The patent utilizes the phase transition of water from liquid to steam to generate high-temperature steam for allergen removal. The steam generator heats water to produce steam at temperatures above 100°C, which then contacts the laundry to kill allergens efficiently, reducing both energy consumption and processing time compared to conventional hot water washing.
Solution Approach 2:
The patent changes the temperature parameter by using steam at temperatures above 100°C instead of conventional hot water at lower temperatures. This parameter change enables faster and more efficient allergen removal, as the higher temperature steam can kill mites and remove allergens more quickly than hot water washing.
3Reliability
If steam is supplied only enough for soaking or sterilization, then conventional washing functions are performed, but allergen removal is inefficient
Solution Approach 1:
The patent changes the temperature parameter by using steam at temperatures above 100°C instead of conventional hot water at lower temperatures. This parameter change enables faster and more efficient allergen removal, as the higher temperature steam can kill mites and remove allergens more quickly than hot water washing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Achieves nearly 100% allergen killing with reduced energy consumption and faster processing compared to hot water methods, ensuring effective removal of mites, animal hair, and pollens while maintaining energy efficiency.
Implementation Method 1
The steam generator evaporates water into high temperature hot steam and supplies the hot steam to the drum 130
Implementation Method 2
The heating part 210 evaporates water into high temperature steam
Implementation Method 3
The spray nozzle 230 is nozzle-shaped to spray the steam smoothly and an outlet end of the nozzle 230 is toward an inside of the drum 130

AI summary
The present invention relates to a laundry machine and a controlling method, which can remove allergens on the laundry. A controlling method of a laundry machine includes a mite-killing step of supplying seam to a drum to make laundry exposed to a hot environment at or over a temperature and for or over a duration of time, wherein the temperature and the duration are predetermined enough to kill house dust mites on the laundry; a rinsing step of rinsing the laundry; and a spin-drying step of spin-drying the rinsed laundry. The present invention has an advantageous effect of removing allergens including house dust mites, animal hair and pollens efficiently. In addition, if the house dust mites are killed by using steam, energy efficiency is high and an effect of mite-killing is great.
