         5 . The food cooking system according to  claim 4 , wherein the lower heating element comprises at least one “bake” resistance. 
     
     
         6 . The food cooking system according to  claim 4 , wherein the upper heating element comprises at least one “broil” resistance. 
     
     
         7 . The food cooking system according to  claim 4 , wherein the rear heating element comprises a convection fan, with a convection heater, a convection motor and a cover. 
     
     
         8 . The food cooking system according to  claim 1 , wherein the appliance comprises a folding door. 
     
     
         9 . The food cooking system according to  claim 1 , wherein the reflective coating comprises TEON. 
     
     
         10 . The food cooking system according to  claim 1 , wherein said at least one food temperature sensor is arranged on an upper surface of the stainless cavity. 
     
     
         11 . The food cooking system according to  claim 1 , wherein said at least one inlet temperature sensor is arranged on an upper surface of the stainless cavity. 
     
     
         12 . The food cooking system according to  claim 1 , wherein said at least one cavity temperature sensor is arranged on an upper surface of the stainless cavity. 
     
     
         13 . Dynamic cooking method in an appliance comprising:
 entering into an appliance user interface a cooking selection that includes a cooking temperature,   determining whether the temperature in a cavity of the appliance is lower than the selected temperature; if the temperature in the cavity of the appliance is lower than the selected temperature, at least one heating element within the cavity of the appliance is switched on,   wherein an appliance cavity temperature sensor measures the temperature at a certain frequency within said appliance cavity,   once the temperature of the appliance cavity has been determined, the previous steps are repeated until the selected temperature is reached;   if the temperature of the appliance cavity is lower than the selected temperature, a preheat work cycle is started, where the appliance cavity is preheated and a cooking process is started by which the heating element is switched on for a certain time;   once the preheat cycle is complete, it is determined again whether the temperature of the appliance cavity is lower than the selected temperature. If it is determined that the temperature of the appliance cavity is equal to or greater than the selected temperature, then a cooking work cycle is started, where the appliance will remain in this cooking state for a selected time;   once it is determined that the temperature of the appliance cavity is equal to or greater than the selected temperature, then the cooking mode selected in the user interface is started, where it is switched on and off for certain times,   the on and off cycle as many times as necessary,   the process ends when the series of conditions imposed when selecting the cycle in the user interface are met.   
     
     
         14 . Dynamic convection cooking method in an appliance comprising:
 entering into an appliance user interface a cooking selection that includes a temperature,   determining, using a temperature sensor, whether the temperature inside an appliance cavity is lower than the selected temperature   if the temperature inside the appliance cavity is lower than the selected temperature, at least one heating element inside the appliance cavity is switched on, wherein the appliance cavity temperature sensor measures the temperature with a certain frequency inside said appliance cavity;   switching on at least one convection element inside the cavity of the appliance;   repeating the two previous steps subsequently until the selected temperature is achieved   if the temperature inside the appliance cavity is lower than the selected temperature, a preheat work cycle is started, where the appliance cavity is preheated and a cooking process is started for a certain time   switching on a convection fan and a broil element for a certain time,   once the preheat cycle is complete, it is determined again whether the temperature inside the appliance cavity is lower than the selected temperature;   if the temperature inside the appliance cavity is determined to be equal to or greater than the selected temperature, then a cooking work cycle is initiated, where the appliance will remain in this cooking state for a selected time   if the temperature inside the appliance cavity is determined to be equal to or greater than the selected temperature, then the convection process is started for a certain period of time subsequently, a cooking mode is started for a certain time,   when the cooking mode is finished, a broil mode starts for a certain time,   once the broil mode is finished, a first adaptation period is allowed, where the first adaptation period lasts from 3 to 10 seconds;   once the adaptation time is finished, the convection fan is switched on for a certain time;   once the convection fan is switched off because its certain time has finished, a second adaptation period is initiated for a certain time,   the cooking work cycle is cycled as many times as necessary until the series of conditions imposed when selecting cooking in the user interface are met.
