The ironing plate body of the iron unit has a preheating channel surrounded by electric heating tubes on the left and right, two heating channels communicating with the rear end of the preheating channel, and a steam channel communicating with the front end of the heating channel. The preheating channel can drain water close to the electric heating tubes. The heating channels are respectively located directly above the electric heating tubes and surround the preheating channel on the left and right. By matching the shape of the electric heating tubes, the spatial structure design of the preheating channel, the heating channel and the steam channel is correspondingly arranged on the ironing plate body, so that water can be quickly heated to boiling and vaporized, greatly shortening the heating and vaporization time and quickly generating a large amount of steam. However, the steam iron of this technical solution is only equipped with one electric heating tube. When continuous use of a large amount of steam is required, the single electric heating tube cannot ensure the vaporization effect, resulting in the risk that the ironing steam may be accompanied by dripping water.
