Improved ease of de-calcification in a steam iron

In conventional steam iron, water from the tank is feed into the steam chamber to generate steam for effective wrinkle removal during ironing. However, evaporating water results in left over residue in the steam chamber since most household taps supply hard water. In time, the build-up of residue, mainly calcium, will eventually affect the efficiency of steam generation. In extreme case, calcium build up may prevent heat transfer to the water, thus preventing the evaporation, which can result in leaking of dirty water onto the clean washed garment during ironing. Therefore, it is essential to perform de-calcification periodically in the life of a steam iron to maintain its performance.

However, the de-calcification feature in all steam irons require user to continually holding onto the calcclean button during the whole process. This creates stress on the finger and results in tiredness & frustration.

This invention eliminates the need for holding onto the de-calcification button during the process. It is made possible by a mechanical locking system that locks the de-calcification button in position. The locking system eliminates the need to hold onto the button and enables user to have a firm grip on iron while shaking. A good shake provides an effective flushing of calcium, which may leads to fewer de-calcification needed. Moreover, there is no stress on the thumb since there is no need to hold onto...
