AI Technical Summary

Technical Problem

Existing garment care devices face issues with inefficient steam vaporization and temperature control in handheld units, leading to spitting and potential damage to fabrics due to condensation and limited power supply, as well as slow temperature adjustments for different fabric types.

Method used

The handheld unit incorporates a cyclonic chamber system with multiple cyclonic chambers and a steam engine to separate and reheat steam, ensuring efficient vaporization and temperature control, using cyclonic chambers to redirect steam flow smoothly and a labyrinth pathway for heating, along with a steam channel and distribution chamber to maintain ironing plate temperature.

Benefits of technology

This design minimizes spitting on garments and allows quick adaptability to various fabric types by ensuring efficient steam generation and temperature control, enhancing ironing performance.

Abstract

The invention relates to a steam generator (SG) comprising an ironing plate (IP) comprising at least one steam vent (SV). The ironing plate defines a planar ironing surface (xy). The steam generator comprises a steam input (IN) for receiving an input steam flow (F1), and an optional first cyclonic chamber. The steam generator also comprises a second cyclonic chamber (CC2) comprising at least one steam inlet (CC2_I) and at least one steam outlet (CC2_O1, CC2_O2). The at least one steam inlet of the second cyclonic chamber is fluidly connected to the steam input. The second cyclonic chamber acts as a fluid separator. The second cyclonic chamber has a second axis of cyclonic rotation being substantially parallel to the planar ironing surface (xy). The at least one steam outlet of the second cyclonic chamber is fluidly connected to the at least one steam vent.
