Heating Apparatus of Hot Drink Machine

Abstract

The present invention provides a heating apparatus of a hot drink machine comprising a conduit pipe extended from a reservoir and connected to an internal heating assembly, a conduit pipe connected between an outlet of the internal heating assembly and a sprinkler outlet on an entrance of a brewing container, a gate for controlling hot water provided on conduit pipe adjacent to sprinkler outlet; characterized in that: said internal heating assembly comprises an electric heating liner surrounding an outer circumference of a stainless steel pipe, and an aluminum material die casted to encompass the electric heating liner on the outer circumference of the stainless steel pipe; whereby heat from said electric heating liner is uniformly distributed on the stainless steel pipe via said aluminum material encompassed said outer circumference thereof such that heat is uniformly transmitted to raw water in said internal heating assembly to increase a heating efficiency thereof.

What is claimed is: 
     
         1 . A heating apparatus of a hot drink machine, said hot drink machine comprising a reservoir for containing a raw water, a conduit pipe extended from a bottom of said reservoir and connected to an internal heating assembly, a conduit pipe connected between an outlet of said internal heating assembly and a sprinkler outlet provided on a top of an entrance of a brewing container, a gate for controlling opening or closing of hot water provided on a section of said conduit pipe adjacent to said sprinkler outlet;
 characterized in that: said internal heating assembly comprises an electric heating liner externally surrounding an outer circumference of a stainless steel pipe of a predetermined diameter, and an aluminum material die casted to encompass said electric heating liner on said outer circumference of said stainless steel pipe; whereby during a heating process of said raw water entering said internal heating assembly, heat from said electric heating liner is uniformly distributed on said stainless steel pipe containing said raw water via said aluminum material encompassed said outer circumference thereof such that said heat is uniformly transmitted to said raw water entering said internal heating assembly to increase a heating efficiency of said internal heating assembly.   
     
     
         2 . A heating apparatus of a hot drink machine, said hot drink machine comprising a reservoir for containing a raw water, a conduit pipe extended from a bottom of said reservoir and connected to an internal heating assembly, a conduit pipe connected to an outlet of said internal heating assembly to a sprinkler outlet provided on a top of a brewing container, a gate for controlling opening or closing of hot water is provided on a section of said conduit pipe adjacent to said sprinkler outlet;
 characterized in that: said conduit pipe connected between said reservoir and said internal heating assembly is provided with a receiving space adjacent to said bottom of said reservoir;   at least two water-level sensors are provided in said receiving space whereby when a water level in said reservoir is lower than said sensors, electricity to said internal heating assembly is shut off by a sensor signal transmitted from a circuit board connected to said sensors such that heating of said internal heating assembly is stopped to prevent any idle heating.
