An ironing roller includes a first annular chamber in communication with an inlet and an outlet arranged to rotate about a longitudinal axis, where the first annular chamber forms a passage through which a heat carrying fluid heated by heating device located inside the ironing roller circulates, a circuit external to the annular chamber being arranged to lead the heat carrying fluid from the outlet to the inlet of the chamber. A second annular chamber adjacent and coaxial to the first annular chamber is provided, the two annular chambers being intercommunicated for the circulation of the heat carrying fluid from one of the annular chambers to the other, and where one of the annular chambers carries out a heat uptake function and the other one carries out a heat transfer function.

1. An ironing roller comprising: a heater disposed therein,at least one first cylindrical wall and one second cylindrical wall, which are concentric and arranged to rotate together about a common longitudinal axis,a first annular chamber being formed between said first and second cylindrical walls in communication with at least one inlet and at least one outlet, said first annular chamber forming a passage through which a heat carrying fluid heated by the heater circulates, andat least one second annular chamber adjacent and coaxial to said first annular chamber, said first and second annular chambers being intercommunicated such that the heat carrying fluid can be circulated from one to the other, said second annular chamber forming a circuit external to said first annual chamber through which the heat carrying fluid is lead from the outlet to the inlet of the first annular chamber,wherein one of said first and second annular chambers performs a heat uptake function for uptaking heat from the heater located inside the roller and the other of said first and second annular chambers performs a heat transfer function for transferring heat to articles to be ironed. 2. An ironing roller having a heater disposed therein, the ironing roller comprising: at least one first cylindrical wall and one second cylindrical wall, which are concentric and arranged to rotate together about a common longitudinal axis,a first annular chamber being formed between said first and second cylindrical walls and in communication with at least one inlet and at least one outlet, where said first annular chamber forms a passage through which a heat carrying fluid heated by the heater circulates,a circuit external to said first annular chamber being arranged to lead the heat carrying fluid from the outlet to the inlet of the first annular chamber, andat least one second annular chamber adjacent and coaxial to said first annular chamber, said first and second annular chambers being intercommunicated such that the heat carrying fluid can be circulated from one to the other, said circuit external to said first annual chamber being carried out through the second chamber and where one of said first and second annular chambers performs a heat uptake function and the other of said first and second annular chambers performs a heat transfer function,wherein the ironing roller comprises a third concentric external cylindrical wall with a larger diameter than a diameter of the second cylindrical wall, said third cylindrical wall being arranged to rotate together with the first and second cylindrical walls about said longitudinal axis, the second annular chamber in communication with the inlet and the outlet of the first chamber being formed between said second and third cylindrical walls, said second annular chamber forming the circuit external to the first chamber for the heat carrying fluid, where the first annular chamber carries out said heat uptake function and the second annular chamber carries out said heat transfer function. 3. A roller according to claim 2, wherein the third cylindrical wall is heated by contact with the heat carrying fluid circulating through the second annular chamber from the outlet to the inlet and provides an external ironing surface suitable for making contact with articles to be ironed. 4. An ironing roller according to claim 3, wherein in at least one of the first annular chamber and/or in the second annular chamber blades inclined with respect to said longitudinal axis are arranged to propel the heat carrying fluid inside the first annular chamber from said inlet to said outlet and inside the second annular chamber from the outlet to the inlet due to the effect of the rotation of the ironing roller. 5. A roller according to claim 4, wherein said blades are arranged inside the first annular chamber. 6. A roller according to claim 4, wherein said blades are arranged inside the second annular chamber. 7. A roller according to claim 4, wherein several first blades of said blades are arranged inside the first annular chamber and several second blades of said blades are arranged inside the second annular chamber, the first and second blades having opposite inclinations with respect to the longitudinal axis. 8. A roller according to claim 3, wherein the inlet of the first annular chamber is connected to one end of the second annular chamber by a first conduit and the outlet of the first annular chamber is connected to another end of the second annular chamber by a second conduit, a pump being connected to one of said first or second conduits to propel the fluid through the first and second chambers, the first and second conduits and said pump being arranged to rotate together with the first, second and third cylindrical walls about the longitudinal axis. 9. An ironing roller having a heater disposed therein, the ironing roller comprising: at least one first cylindrical wall and one second cylindrical wall, which are concentric and arranged to rotate together about a common longitudinal axis,a first annular chamber being formed between said first and second cylindrical walls and in communication with at least one inlet and at least one outlet, where said first annular chamber forming a passage through which a heat carrying fluid heated by the heater circulates,a circuit external to said first annular chamber being arranged to lead the heat carrying fluid from the outlet to the inlet of the first annular chamber, andat least one second annular chamber adjacent and coaxial to said first annular chamber, said first and second annular chambers being intercommunicated such that the heat carrying fluid can be circulated from one to the other, said circuit external to said first annual chamber being carried out through the second chamber and where one of said first and second annular chambers performs a heat uptake function and the other of said first and second annular chambers performs a heat transfer function,wherein the second annular chamber adopts the form of at least one coil located inside the first annular chamber and arranged to rotate together with the first and second cylindrical walls about said longitudinal axis, where the second annular chamber in the form of a coil carries out said heat uptake function and the first annular chamber carries out said heat transfer function, and where the second annular chamber in the form of a coil further carries out the function of propelling the heat carrying fluid inside the first annular chamber from said inlet to said outlet and inside the second annular chamber from the outlet to the inlet due to the effect of the rotation of the ironing roller. 10. A roller according to claim 9, wherein the mentioned coil forming the second annular chamber has the shape of a helical tube with ends connected to the inlet and to the outlet of the first chamber, respectively, where the second cylindrical wall provides an external ironing surface suitable for making contact with the articles to be ironed. 11. A roller according to claim 1, wherein said at least one inlet is located in or adjacent to a first end of the first annular chamber and in communication with an outlet arranged in or adjacent to a first end of the second annular chambers, and said at least one outlet is located in or adjacent to a second end of the first annular chamber opposite to the first end thereof and in communication with an inlet arranged in or adjacent to a second end of the second annular chamber opposite to the first end thereof. 12.
