         4 . The system according to  claim 1 , further comprising:
 at least one structure cooperating with the at least one panel, wherein the structure comprises at least one support element cooperating with the at least one abutment surface.   
     
     
         5 . The system according to  claim 4 , wherein the at least one structure comprises a drip reservoir. 
     
     
         6 . The system according to  claim 4 , wherein the at least one structure comprises a drawer. 
     
     
         7 . The system according to  claim 4  or  5  wherein the at least one structure comprises at least one gap cooperating with the at least one diffuser. 
     
     
         8 . The system according to  claim 1 , further comprising:
 at least one mass metering device cooperating with the at least one panel.   
     
     
         9 . The system according to  claim 1 , further comprising:
 at least one temperature metering device cooperating with the at least one internal compartment.   
     
     
         10 . The system according to  claim 1 , wherein the system cooperates with at least one controller board which cooperates with at least one user interface. 
     
     
         11 . The system according to  claim 10 , wherein the at least one user interface cooperates with an electronic device. 
     
     
         12 . The system according to  claim 1 , further comprising:
 a device configured to provide information about a total time estimated for defrosting, remaining processing time for ending the process, or about an end of the process, wherein the device comprises at least one user interface cooperating with at least one controller board, and at least one electronic device cooperating with the at least one user interface.   
     
     
         13 . A method for freezing and defrosting at least one food product in an electrical household appliance device comprising doors which allows access to at least one internal compartment for at least one of refrigerating or freezing the at least one food product, wherein the method comprises the steps of:
 informing the device of a product type to be processed;   positioning the food product inside of the device;   actuating the device via pre-inserted information related to the food product to be processed, wherein the device has a controller board which automatically calculates an estimated time necessary for defrosting;   selecting between a total time of defrosting and other information provided by the controller board;   at the end of the necessary time for defrosting, actuating a system that maintains refrigeration of the at least one internal compartment, presents the information of complete defrost, and starts a timing from the end of the defrosting;   monitoring an opening of the device door, wherein such opening indicates that the processed product has been at least one of accessed or removed from an interior of the device,   wherein, if the door is opened before a predetermined time interval, the system is restarted, and if the door is not opened during the predetermined time interval, the defrosting is reactivated and the food product is refreezed.   
     
     
         14 . An electrical household appliance device comprising a convertible system for freezing and defrosting at least one food product comprising at least one door that allows access to internal compartments for at least one of refrigeration or freezing of at least one food product, wherein the convertible system comprises:
 at least one compartment with external access and cooperating with the at least one door, wherein the at least one compartment comprises:
 at least one heater cooperating with a bottom region of the at least one compartment;
