Description

Technical Field

[0001] This utility model relates to the field of steam irons, and in particular to a soleplate structure for an electric iron with a large steam capacity. Background Technology

[0002] As a household appliance, the electric iron has been an essential tool for ironing clothes since its invention. With technological advancements and improved living standards, the design and function of electric irons have continuously evolved, especially the structure of the soleplate, which directly affects ironing efficiency and garment care. Traditional electric iron soleplate structures are mainly divided into two types: single-cavity and multi-hole steam jet, but these designs have certain limitations and drawbacks.

[0003] Steam irons work by heating water into steam on the soleplate and then releasing the steam through the soleplate for ironing. However, because the water is heated internally and then directly released, water droplets remain in the steam, affecting the ironing results.

[0004] Currently, most improvements to the soleplate of steam irons address the above issues by increasing the heating temperature of the water and improving heating efficiency, so that the water in the base can be vaporized into steam more efficiently. However, if the heating temperature is increased, the excessively high temperature inside the soleplate can easily affect the temperature sensing element inside the soleplate, causing abnormal temperature detection by the temperature sensing element and affecting the ironing effect.

[0026] The vaporization cover 2 is provided with a cold water inlet 7 for cold water to enter. The cold water inlet 7 is connected to one end of the first vaporization channel 4, and the first end of the diversion channel is connected to the end of the first vaporization channel 4 away from the cold water inlet 7. Specifically, a number of baffles 8 are evenly distributed in the first vaporization channel 4 to increase the residence time of water in the base plate body 1 and to allow it to fully absorb heat. The baffles 8 are arranged perpendicular to the bottom surface of the base plate body 1 and extend upward to a certain height.
