1. An intelligent electronic system for previously sensing the dryness condition of a textile clothes load, applicable to an automatic electronic clothes dryer machine, comprising a main body or cabinet; a rotatory drum arranged in the center of the dryer machine; heating means located preferably on the lower portion of the drum; a first motor located on the lower portion of the dryer machine for rotating said drum; a propeller fan located on the lower portion of the dryer machine; an outlet conduit arranged on the lower portion of the dryer machine; a control panel located on the outside on the upper section of the front wall of the dryer machine; said main body or cabinet shape includes on its front wall an opening with a hinged door arranged thereon, which allows or prevents access to the inside of the drum of said dryer machine, allowing to place objects or textiles inside said drum; wherein the dryer machine further comprises:
i. an electronic integrated circuit of the microcontroller type, located integrally on the mainboard of a dryer machine, preferably located on the control panel, said microcontroller further comprises a memory to store preloaded conditions and parameters, in order to make decisions based on a verification; ii. temperature sensing means for sensing temperature and sending signals of said sensed temperature to the microcontroller, located preferably at the drum's air outlet and inlet; iii. humidity sensing means for sensing humidity and sending signals of said sensed temperature to the microcontroller, located preferably at the drum's air outlet and inlet; wherein the intelligent electronic system for previously sensing the dryness condition of a textile clothes load of the dryer machine, further comprises the steps of: (a) Collecting information on the air temperature of the drum's outlet and inlet by using temperature sensing means, which send pulses or signals to the microcontroller, similarly pulses or signals of the humidity condition of the textiles clothes load are sent to the microcontroller by using humidity sensing means; the microcontroller having said signals or pulses received, then determines the initial conditions of the dryer machine prior to starting up the motor of said dryer machine; (b) Determining, with the information obtained in the step a) above, whether the dryer machine is cold or warm and comparing said information with parameters previously programmed; (c) Letting a first period of time to elapse during which pulses or signals of air temperature conditions of the drum's outlet and inlet will continue being received via the temperature sensing means, as well as the humidity conditions via the humidity sensing means of said textile clothes load; (d) Check whether or not said conduit is obstructed; (e) Letting a second period of time to elapse during which measuring of air temperature conditions of the drum's outlet and inlet, as well as humidity conditions of said textile clothes load continues; (f) Determining whether the textile clothes load is large or small by calculating a second heating slope as well as a third heating slope by using incoming data from the outlet and inlet temperature sensors, respectively; wherein the absolute value of the arithmetic difference of both slopes are compared with a preset parameter; if said difference between slopes is lower than the preset value, then the load is considered to be small; otherwise the load is considered to be large. (g) Determining humidity conditions of the textile clothes load; if the load is small the load checked for humidity or dryness, this is done via the humidity sensing means by comparison of the actual value against a reference preset value; if the load is dry, then the microcontroller instructs to stop the drying cycle, otherwise it instructs to continue with the normal drying cycle. (h) Letting a third period of time to elapse during which the microcontroller continues to read and store data from both the drum's outlet and inlet temperature sensors, as well as to get readings from the humidity sensing means. (i) Determining humidity conditions of the textile clothes load; if said load is large, this is realized by means of the drum's outlet temperature sensors, which values are compared with a reference preset value; if the load is dry, then the microcontroller instructs to stop the drying cycle, otherwise it instructs to continue with the normal drying cycle. (j) Reviewing humidity by zones, this is performed by means of the humidity sensing means, in order to calculate a humidity condition, once the microcontroller has calculated said data, it compares it with a humidity preset parameter for large loads; if the microcontroller determines the absence of humidity zones, then it instructs to stop the drying cycle, otherwise it instructs to continue with the normal drying cycle. |
