Dryer Steam And Additive Control Without External Water Supply
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dryers do not effectively remove wrinkles and bad smells from laundry, requiring additional ironing and fragrance application, and often require external water supply facilities, limiting their usability.
Innovation Solution
A drum-type dryer with integrated steam and additive supply systems that use steam generators and additive pumps to provide steam and fragrance directly to the laundry, along with an air supply system to enhance moisture absorption and reduce static electricity, allowing for detachable water and additive holding parts for convenience and reduced water usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external water supply facilities are required for dryer operation, then steam generation function is enabled, but installation complexity and safety risks increase
Solution Approach 1:
The water supply system is segmented into a removable water tank that can be detached from the main dryer body. This allows the dryer to be installed without permanent water supply connections, as the tank can be manually filled and attached. The segmentation separates the water storage function from the steam generation function, enabling flexible installation.
Solution Approach 2:
The dryer employs a self-service water supply mechanism where the user manually fills the removable water tank rather than requiring automated connection to external water facilities. This eliminates the need for complex water supply infrastructure while maintaining steam generation capability.
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
The dryer effectively removes wrinkles and bad smells, adds fragrance, and can operate without additional water supply facilities, enhancing user convenience and reducing the need for ironing, while optimizing functions beyond basic drying.
Implementation Method 1
a steam generation device to supply steam to the drum
Implementation Method 2
a steam generator that generates steam
Implementation Method 3
a pump that pumps the additive held in the additive holding part to generate a hydraulic pressure

AI summary
A laundry machine, more particularly, a dryer and a control method of a dryer may be disclosed. A control method of a dryer includes (a) of supplying an additive to a drum in an initial part of a drying cycle for drying a drying object; and (b) of supplying an additive to the drum in a last part of the drying cycle.
