Integrated Soleplate Steam Distribution for Condensation Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing steam irons with external steam distribution modules are bulky, expensive, and prone to steam condensation, leading to water droplet emission during use.
Innovation Solution
A steam iron with a steam distribution device that includes a sealable steam distribution chamber integrated into the soleplate, allowing for steam flow concentration towards specific outlet holes, using a deformable seal operated from outside the iron to block or reduce steam flow to secondary outlet holes, thereby reducing condensation risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an external steam distribution module is used to concentrate steam flow, then steam flow can be concentrated towards specific outlet holes, but the device becomes bulky and expensive
Solution Approach 1:
The patent merges the steam distribution device with the soleplate by integrating the distribution chamber directly into the soleplate structure. The bottom of the distribution chamber is formed by the soleplate itself, eliminating the need for separate external modules. This integration maintains the steam concentration function while simplifying the overall device structure.
Solution Approach 2:
The soleplate serves multiple functions: it acts as both the heating element support and the bottom wall of the steam distribution chamber. The cover of the soleplate forms part of the distribution chamber structure, combining structural support and steam distribution functions in a single component system.
2Ease of operation
If an external steam distribution module is used, then steam flow can be controlled, but steam condensation occurs in the cold area causing water droplet emission
Solution Approach 1:
The distribution chamber is positioned within the heated zone of the soleplate, so steam is distributed while still hot, before it has a chance to cool and condense. The integration ensures steam remains in the warm environment of the soleplate throughout the distribution process.
Solution Approach 2:
The deformable seal acts as a controlled intermediary that can be positioned to block or allow steam flow to different outlet groups. This seal provides precise control over steam distribution without requiring complex external mechanisms, maintaining steam temperature and preventing condensation.
3Adaptability or versatility
If a deformable seal is used to block steam flow, then steam can be concentrated to specific areas, but the seal must be operated from outside the iron
Solution Approach 1:
The seal is designed to be deformable rather than fixed, allowing it to change position dynamically. An actuating element can press against the seal to deform it and block steam flow to specific outlets, providing flexible control. When the actuating force is removed, the seal returns to its original position, automatically resetting the steam distribution without complex mechanical linkages.
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 solution provides a compact, economical, and efficient steam distribution system that maintains steam heating and reduces condensation, allowing for concentrated steam flow to specific areas for improved ironing performance.
Implementation Method 1
the seal being elastically brought into a rest position in which the steam can travel freely from the inlet orifice to the outlet orifice and being able to be deformed, under the pressure of an actuating element
Implementation Method 2
a steam distribution chamber the bottom of which is formed by a closing cover attached to the soleplate, the distribution chamber including at least one supply orifice, provided in the cover, opening into a conduit connected to a steam inlet channel

AI summary
The iron (1) has an ironing plate (2) comprising a set of groups of steam outlet holes (20). A distribution chamber (6) has a feed orifice (42) formed in a cover that is opened in a main duct connected to a steam inlet channel. The inlet channel is integrated into a sole (3). An outlet is formed in the cover resulting in a network of vapor diffusion in a direction of one of the groups of the steam outlet holes. A joint (7) is provided on the cover for reducing or blocking vapor supply.
