Definitions
- the subject of the present invention is a drying process improved linen and a machine using it.
- the subject of the present invention is a method allowing improve the drying of laundry in a washer-dryer machine or drying, decreasing, at equal efficiency, the drying time, and this, as simply as possible.
- the present invention also relates to a machine implementing the method of the invention.
- the process of the invention consists, in the drying phase of the laundry, rotating the drum at an "improved drying" speed slightly lower than the centrifugation speed of its contents. In a way advantageous, this speed is between 65 and 70 revolutions / min approximately.
- the phase has several stages, during each of which the drum rotation speed is different from one step to the next, advantageously by alternating steps at higher speed, at high speed equal and at lower speed than the speed of "improved drying".
- the speed can vary, for example, by a speed minimum of about 35 to 50 rpm at a maximum speed of about 70 to 100 rpm.
- the present invention relates equally to machines washer-dryers than only drying machines, these machines can be front loading or top loading. For simplify, in the following description, they will be qualified only as machines.
- the machine 1 represented in FIGS. 1 and 2, comprises, between others, a drum 2 rotating around its axis 3 in a tank 4.
- the hot air circulation circuit of the machine 1 comprises a turbine 5 of which the air suction pipe 6 is connected to the upper part of the tank 4, and whose air injection pipe 7 is connected to the tank, coaxially with axis 3.
- the other parts of the mixing circuit hot air have not been shown.
- the "pipe” 9 has a diameter which depends on the speed of rotation of the drum, and which is equal or slightly greater than the diameter of the pipe 7.
- the laundry items near hose 9 are much less subject to centrifugal force than those which are further away from this pipe, and can move relative to others pieces of laundry, migrating from the axis to the periphery of the drum, ensuring thus a brewing of linen and improving the uniformity of drying.
- the speed drum rotation in drying mode is not maintained constant. It can vary in stages or gradually around the improved drying speed, between two limits which are for example 35 rpm and approximately 100 rpm, and can alternately increase and decrease between these two limits. It is advantageous to plan short breaks during the drying phase, allowing the laundry to fall to the bottom of the drum when it stops, and be distributed differently when the drum resumes rotation.
- the different speed steps or different drum rotation speeds can correspond to different stages of drying the laundry: start, middle and end of drying, and linen cooling. At each stop, the drum can change direction rotation, so as not to tangle the laundry, to promote uniformity drying and limit wrinkling of this laundry.

Claims (8)
- Procédé de séchage amélioré du linge dans une machine (1) lavante-séchante ou séchante, caractérisé en ce que pendant la phase de séchage du linge qui peut comporter plusieurs étapes, on fait tourner le tambour (2) à une vitesse dite de "séchage amélioré" inférieure à la vitesse de centrifugation de son contenu, cette vitesse de séchage amélioré étant comprise entre 65 et 70 t/min environ.
- Procédé selon la revendication 1, caractérisé en ce que pendant la phase de séchage on fait varier la vitesse de rotation du tambour (2) autour de la vitesse de séchage amélioré.
