Abstract

A drying method in a dryer machine which involves sending a pulse according to a pulse pattern formed by: energizing each of a plurality of actuators of a heater for a first determined set time; de-energizing one actuator of the heater for a second determined set time; de-energizing another actuator of the heater for a third determined period of time; compare, during the previous steps, the temperature detected by a temperature detector versus a target value; in case the temperature detected is higher than the target value, interrupting a drive signal to drivers for the heater; in case the temperature detected is lower than the target value, uninterrupting the signal to the drivers; and repeat the previous steps at least one time.

Claims

1. A drying method in a dryer machine comprising a drum, at least one electric control, one pulse generator, at least one temperature detector, one interface for the operator and at least one heater with a plurality of actuators, at least one driver per actuator, comprising sending a pulse to the drivers from the electric control, according to a pulse pattern received from the pulse generator, where a generating of the pulse pattern comprises:

a. energizing each of the plurality of actuators of said at least one heater for a first determined set time;

b. de-energizing one actuator of aid at least one heater for a second determined set time;

c. de-energizing another actuator of said at least one heater for a third determined set time;

d. concurrently with the foregoing steps, comparing an air temperature entering or exiting the drum detected by a first temperature detector relative to a target value varying between approximately 5°

C. to 25°

C. above a temperature threshold that varies between 37.77°

C. to 65.55°

C.;

e. when the detected temperature is higher than the target value, interrupting a drive signal to the drivers;

f. when the detected temperature is lower than the target value, uninterrupting the drive signal to the drivers; and

g. repeating steps (a) through (d) at least one time.

2. The method according to claim 1, prior to energizing each of the plurality of actuators further comprising determining if an energy savings setting was selected on the operator interface, and, if the energy savings setting was selected, modifying a temperature threshold of said at least one heater to a lower threshold varying between approximately 37.77°

C. to 65.55°

C. by means of the control.

3. The method according to claim 1, further comprising selecting the pulse generator from the group consisting of a microcontroller, an electro-mechanic generator and a digital pulse generator.

4. The method according to claim 1, where the first determined set of time varies in a range from 10 seconds to 3 minutes, where the second determined set of time varies in a range from 10 seconds to 4 minutes and where the third determined set of time varies in a range from 30 seconds and 4 minutes.
