Description

The present invention relates to the field of steam generators, and more particularly to multi-passage steam generators.

A steam atomizing iron uses a heating element to vaporize water into steam during operation, thereby achieving the purpose of ironing clothes. Due to structural and spatial constraints, the steam generators currently used for irons on the market basically have a single steam generation passage, which tends to generate limescale during operation and causes mist. If the degree of atomization was insufficient, water droplets were likely to form and clog the steam passage, and the clogging caused by steam atomization affected the life of the iron.

For example, a handheld pressure steam iron disclosed in Patent Document 1 includes a housing and a bottom plate having at least one steam outlet installed at the lower end of the housing, and the bottom plate includes a bottom plate electric heating tube, a bottom plate temperature controller. is installed, the bottom plate heating tube and bottom plate temperature controller are electrically connected, a boiler is installed inside the casing, the boiler heating tube is installed at the bottom of the boiler, and separate heating is applied to the boiler and bottom plate. This allows the bottom plate to be ironed at a low temperature of 100 to 130 degrees, preventing damage to clothing. A water inlet is provided on the boiler, a boiler safety valve is installed on the water inlet, and a steam pipe is further installed on the boiler to transport steam to the bottom plate.

As can be seen from the structure of the above-mentioned disclosed patent, a single steam flow path used for circulating steam is formed by a steam pipe, a vaporization chamber, and a steam outlet, and there is no possibility of clogging during operation. This can easily affect the lifespan of the product.
