Steaming Head Internal Chamber Design to Prevent Water Droplet Stains
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Steam steamers often project or capture water droplets through steam outlet holes, causing stains on garments due to capillary action, which existing designs fail to effectively prevent.
Innovation Solution
A steaming head with a steam distribution circuit featuring an inlet duct with a tangential outlet orifice into an internal chamber, containing steam expulsion channels that extend transversely to the front wall, promoting steam flow around the channels and separating water droplets from the steam before they can penetrate the outlet holes, thus reducing condensation and capillary capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If steam flows freely through outlet holes to treat garments, then steaming effectiveness is improved, but water droplets are projected or captured causing stains
Solution Approach 1:
The patent applies preliminary action by heating the steam expulsion channels before steam flow reaches them. The inlet channel directs steam to first heat the internal chamber and expulsion channels, raising their temperature above the dew point before steam exits through outlet holes. This preliminary heating prevents condensation of water droplets during the steaming process, allowing effective steam treatment without staining.
2Productivity
If steam velocity is increased to improve steam distribution, then steaming performance is improved, but water droplet projection increases
Solution Approach 1:
The patent changes the temperature parameter of the steam expulsion channels from ambient or cool temperatures to heated temperatures above the dew point. This parameter change allows high-velocity steam flow to pass through without condensing into water droplets, thereby maintaining effective steam distribution while preventing water droplet projection and capillary absorption that would cause stains.
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 design significantly limits the risk of water droplets being projected or captured on garments, maintaining a simple and economical structure while ensuring effective steam distribution and minimizing water stains.
Implementation Method 1
This configuration of the steamer head, and more specifically of the steam expulsion channels and the outlet, generates a flow of steam entering the internal chamber around the steam expulsion channels, thus heating them, before the steam escapes from the steamer head via the steam expulsion channels
Implementation Method 2
the outlet orifice opens into an internal chamber tangential to the front wall so that the steam exiting the outlet orifice flows along the front wall... promotes vapor circulation in the internal chamber before it can enter the vapor expulsion channels, which allows separation of at least some of the water droplets carried by the vapor from the vapor flow

AI summary
The steaming head (6) includes a steam distribution circuit (16) comprising an inlet channel (17) including an inlet orifice (18) intended to be connected to a steam conduit; and a front wall (10) provided with a treatment face (12) including at least one steam outlet hole (13) and intended to come into contact with a garment to be steamed. The inlet channel (17) has an outlet orifice (19) opening into an internal chamber (21) tangentially to the front wall (10) such that the steam exiting the outlet orifice (19) flows along the front wall (10), the internal chamber (21) having steam expulsion channels (29) extending transversely to the front wall (10) and communicating with at least one steam outlet hole (13) so that the steam present in the internal chamber (21) escapes through the steam expulsion channels (29) and towards at least one steam outlet hole (13).
