Abstract

A cordless ironing apparatus includes an iron and an ironing board adapted to be used with the iron. The iron includes a soleplate. The ironing board includes an ironing surface on which fabric is placed and an electromagnetic generator. The electromagnetic generator is adapted to generate an electromagnetic field which generates heat in the soleplate of the iron. Alternatively, the ironing apparatus includes an iron and an induction device which is removable or separate from an ironing board. The induction device includes an electromagnetic generator which is adapted to generate an electromagnetic filed which generates heat in the soleplate of the iron.

Claims

1. An ironing apparatus comprising:

an iron comprising;

a soleplate having a first axis oriented along a major dimension of the soleplate, a second axis perpendicular to the first axis and oriented along a minor dimension of the soleplate, wherein the soleplate is symmetrical along both the first and second axes, and a first tip and a second tip located at opposite ends of the soleplate along the first axis;

a water tank;

a symmetrical handle oriented and aligned in a direction along the first axis of the soleplate, a first steam activating button and a first spray nozzle located proximate to a first tip of the soleplate; and

a second steam activating button and a second steam spray nozzle located proximate to a second tip of the soleplate;

an electromagnetic generator in displaceable electromagnetic communication with the soleplate, adapted to induce an electromagnetic field that heats the soleplate;

wherein said soleplate is heated when said soleplate is placed in electromagnetic communication with said generator; and

wherein said soleplate is not heated when said soleplate is not placed in electromagnetic communication with said generator.

2. The ironing apparatus of claim 1, wherein the electromagnetic generator is retained in a docking station with a docking port sized to releasably receive the soleplate.

3. The ironing apparatus of claim 1, wherein said soleplate is releasably attached to the iron.

4. The ironing apparatus of claim 1, further comprising a set of steam holes located on the soleplate for delivering a burst of normal steam.

5. The ironing apparatus of claim 1, wherein the electromagnetic generator comprises a high-frequency electromagnet.

6. The ironing apparatus of claim 1, further comprising an ironing surface, wherein the electromagnetic generator is disposed under the ironing surface.

7. The ironing apparatus of claim 1, wherein the electromagnetic generator comprises a thermal sensor.

8. The ironing apparatus of claim 1, wherein the electromagnetic generator comprises a controller coupled to a thermal sensor adapted to control the temperature of the soleplate.

9. The ironing apparatus of claim 1, wherein the electromagnetic generator comprises one or more of a power cord or a rechargeable battery.

10. The ironing apparatus of claim 1, wherein the iron is cordless.

11. An ironing system, comprising:

an ironing board attached to a docking station;

an iron comprising;

a soleplate having a first axis oriented along a major dimension of the soleplate, a second axis perpendicular to the first axis and oriented along a minor dimension of the soleplate, wherein the soleplate is symmetrical along both the first and second axes, and a first tip and a second tip located at opposite ends of the soleplate along the first axis;

a water tank;

a symmetrical handle oriented and aligned in a direction along the first axis of the soleplate;

a first steam activating button and a first spray nozzle located proximate to a first tip of the soleplate; and

a second steam activating button and a second steam spray nozzle located proximate to a second tip of the soleplate;

an electromagnetic generator retained in said docking station with a docking port sized to receive the soleplate and in displaceable electromagnetic communication with said soleplate;

wherein said soleplate is heated when said soleplate is placed in electromagnetic communication with said generator; and

wherein said soleplate is not heated when said soleplate is not placed in electromagnetic communication with said generator.

12. The ironing system of claim 11, wherein the docking station is releasably attached to the ironing board.

13. The ironing system of claim 11, wherein the electromagnetic generator comprises one or more of a power cord or a rechargeable battery.

14. The ironing system of claim 11, wherein the iron is cordless.

15. A method of operating an ironing system, comprising:

generating an oscillating electromagnetic field;

placing a soleplate of an iron in proximity to the electromagnetic field, wherein the iron comprises a soleplate having a first axis oriented along a major dimension of the soleplate, a second axis perpendicular to the first axis and oriented along a minor dimension of the soleplate, wherein the soleplate is symmetrical along both the first and second axes, and a first tip and a second tip located at opposite ends of the soleplate along the first axis;

a water tank;

a symmetrical handle oriented and aligned in a direction along the first axis of the soleplate, a first steam activating button and a first spray nozzle located proximate to a first tip of the soleplate; and

a second steam activating button and a second steam spray nozzle located proximate to a second tip of the soleplate;

inducing heat in the soleplate until a desired temperature is achieved; and

moving said soleplate along a surface in electromagnetic communication with said electromagnetic field.

16. The method according to claim 15, further comprising the step of removing the soleplate from said electromagnetic communication with the oscillating electromagnetic field.
