Description

Steam electric iron TECHNICAL FIELD

[0001] The present application relates to the technical field of irons, in particular to a steam electric iron. BACKGROUND

[0002] The bottom plate of the electric iron on the market is directly pumped by the water pump to the bottom plate of the iron, and the water is heated in the bottom plate of the iron to generate steam, which is sprayed from the steam hole of the bottom plate of the iron to iron clothes. During the ironing process, due to insufficient heat exchange between the steam chamber of the bottom plate of the iron and the water, the water cannot be fully vaporized, resulting in low ironing efficiency, and even causing water droplets to be sprayed out of the iron during ironing, wetting the clothes.

[0003] A Chinese invention patent with authorization announcement No. CN217419091U discloses a base applied to a steam iron, which comprises an iron bottom plate, a surrounding plate arranged on the upper end face of the iron bottom plate and extending upward, and an inner cavity formed by the surrounding plate and the iron bottom plate, a partition plate arranged in the inner cavity, the partition plate separating the inner cavity into a gasification cavity and an exhaust passage, an air outlet arranged in the exhaust passage and penetrating through the lower end face of the iron bottom plate, a gasification passage arranged between the gasification cavity and the exhaust passage, and a heating element arranged on the iron bottom plate and used for heating the gasification cavity, the exhaust passage and the gasification passage. During operation, the water in the gasification cavity is heated and warmed by the heating element, and then vaporized into water vapor, which flows along the gasification passage and the exhaust passage to the air outlet and is released. The prior art prolongs the steam release path and continuously heats the steam flowing through the path by the heating element, so that the solid-liquidization is more sufficient, thereby effectively solving the problem of water droplets entrained in the steam. However, the prior art still has structural deficiencies, it cannot achieve sufficient separation of water vapor before steam is discharged, and because calcium, magnesium ions and other substances in the water will form solid white precipitates after being heated at high temperature, white precipitates will form in the steam release path, which will form stains on the clothes when ironing, dirtying the clothes.

[0004] Therefore, there is still room for improvement and development in the prior art. TECHNICAL SOLUTION
