[0001] The utility model relates to the technical field of irons, in particular to a bottom plate flow channel structure of a steam iron. Background Art
[0002] A steam iron is a household appliance, and its main function is to remove wrinkles on clothes and fabrics. Using an iron can make clothes look smoother and neater. In addition, the steam of the steam iron can sterilize and disinfect, which helps to maintain the hygiene of clothes. Compared with an ordinary iron, a steam iron can iron large areas of clothes more conveniently, without leaving obvious marks, and a steam iron can iron heavy items more easily, and can also better reduce the risk of local overheating and scalding.
[0003] However, in existing steam irons, a heating structure is generally arranged inside the steam iron to vaporize water, so as to generate steam for ironing. However, the heating path of the existing steam iron is too short, resulting in the sprayed steam not being dense enough, and water droplets being carried in the steam, thus affecting the ironing effect.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0028] It should be understood that although terms such as upper, middle, lower, top, one end, etc. appear in this text to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish elements from each other for easy understanding, rather than to define any directional or sequential limitations.
[0029] As Figure 1-6 shown, a bottom plate flow channel structure of a steam iron includes an ironing main body 1, a water pumping component 2 arranged in the ironing main body 1, and an ironing board component 3 arranged at the bottom of the ironing main body 1. The ironing board component 3 includes an ironing soleplate 101 and a heating plate 102 arranged on the ironing soleplate 101.

An air outlet cavity 105 is formed on the outer periphery of the second heating area. A plurality of air outlet holes 106 are formed at the bottom of the ironing soleplate 101, and the air outlet holes 106 communicate with the air outlet cavity 105.
[0031] Furthermore, a first heating channel 107 and a second heating channel 108 are formed on the first heating area 103, and the second heating area 104 forms a return channel 109 and an air outlet channel 110. The output end of the first heating channel 107 communicates with the input end of the return channel 109, the output end of the return channel 109 communicates with the input end of the second heating channel 108, the output end of the second heating channel 108 is connected to the input end of the air outlet channel 110, and the output end of the air outlet channel 110 communicates with the air outlet cavity 105.
[0032] During the entire vaporization process, water is first placed into the first heating channel 107 through the water pumping assembly 2 for the first heating, then enters the return channel 109 for the second heating, then returns to the second heating channel 108 for the third heating, and finally flows into the air outlet cavity 105 through the air outlet channel 110 and is discharged from the air outlet holes 106. This greatly increases the vaporization path and distance of water, enables water to be fully vaporized, makes the ejected steam more dense, and does not entrain water droplets, thereby greatly enhancing the ironing effect.

[0045] Among them, the water-guiding rib 401 on the top of the heating plate 102 is covered with a cover plate, thereby enclosing a first heating area 103, and the water-guiding rib 401 at the bottom of the heating plate 102 is in contact with the ironing base plate to enclose a second heating area 104, so that water is heated and vaporized into water vapor multiple times in the first heating area 103 and the second heating area 104, which greatly increases the vaporization stroke and makes the ejected steam denser.
[0046] A positioning groove 404 for the water-guiding rib 401 to be placed is formed on the ironing sole plate 101 , thereby increasing the stability of the connection between the ironing sole plate 101 and the heating plate 102 and increasing the sealing performance of the second heating area 104 .
