This disclosure relates to the field of ironing in general, and more specifically to an automatic ironing apparatus and an associated method of automatic ironing.
The following discussion of the background art is intended to facilitate an understanding of the present disclosure only. The discussion is not an acknowledgement or admission that any of the material referred to is or was part of the common general knowledge as at the priority date of the application.
As is generally known in the art, ironing is the act of smoothing or pressing, typically with a heated iron, clothes, linens or similar fabrics or materials in order to remove wrinkles. As such, ironing typically involves the use of a small appliance, usually a heated tool (such as an iron), to remove wrinkles from fabric. A temperature of the heated iron typically depends on the material or fabric to be ironed, with common temperature around 180-220° Celsius (356-428 Fahrenheit).
Ironing generally works by loosening the bonds between the long-chain polymer molecules in the fibers of the material. While the molecules are hot, the fibers are straightened by the weight of the iron, and they hold their new shape as they cool. Some fabrics, such as cotton, require the addition of water to loosen the inter-molecular bonds. Similarly, other chemicals may be used to facilitate the ironing process.
While ironed clothes typically provide a neat, professional and well-groomed appearance to a wearer, the task or ironing is generally arduous and time-consuming. As a result, many people spend considerable time every day ironing clothes for work and social gatherings where a neat and professional appearance is desired.
The current disclosure was conceived with the goal in mind of automating ironing, or at least ameliorating conventional ironing practices.
