Heating appliance structure

Abstract

A heating appliance structure is provided, including: a cylinder, provided with a heating area and a water storage area; a heat-isolating portion, defining the heating area having an opening in the water storage area and entirely located within the water storage area, the at least one gap being part of the water storage area and directly communicating with the heating area; a heating pipe, wherein the heating pipe extends into the heating area and is located entirely within the heating area; a water inlet pipe, wherein the water inlet pipe channels water into the water storage area within the cylinder from an exterior of the cylinder; a water outlet pipe, wherein the water outlet pipe channels out heated water from the cylinder to the exterior of the cylinder.

What is claimed is: 
     
         1 . A heating appliance structure, comprising:
 a cylinder, the cylinder is capable of water storing, which allows an input and output of water, an interior of the cylinder is provided with a heating area and a water storage area;   a heat-isolating portion, at least one end of the heat-isolating portion connected to the cylinder, the heat-isolating portion extending laterally inward, the heat-isolating portion itself bending concavedly and defining the heating area, the heating area having an opening in the water storage area, the heat-isolating portion being entirely surrounded by and entirely located within the water storage area, the heat-isolating portion and the cylinder forming at least one gap therebetween, the at least one gap being part of the water storage area and directly communicating with the heating area;   a heating pipe, wherein the heating pipe extends into the heating area and is located entirely within the heating area;   a water inlet pipe, wherein the water inlet pipe channels water into the water storage area within the cylinder from an exterior of the cylinder;   a water outlet pipe, wherein the water outlet pipe channels out heated water from the cylinder to the exterior of the cylinder.   
     
     
         2 . The heating appliance structure according to  claim 1 , wherein the opening of the heating area faces downwardly. 
     
     
         3 . The heating appliance structure according to  claim 1 , wherein the heat-isolating portion is substantially C-shaped. 
     
     
         4 . The heating appliance structure according to  claim 3 , wherein the heat-isolating portion arcuately extends for larger than 80 degrees. 
     
     
         5 . The heating appliance structure according to  claim 4 , wherein the heat-isolating portion arcuately extends for larger than 180 degrees relative to the heating pipe. 
     
     
         6 . The heating appliance structure according to  claim 1 , wherein the heat-isolating portion is hollow. 
     
     
         7 . The heating appliance structure according to  claim 1 , wherein the water inlet pipe does not protrude into the water storage area. 
     
     
         8 . The heating appliance structure according to  claim 1 , wherein the water outlet pipe does not protrude into the water storage area. 
     
     
         9 . The heating appliance structure according to  claim 1 , wherein the heat-isolating portion bends transitionally and has two transitional corner portions, and a distance between the heat-isolating portion and the heating pipe is smaller than a radial size of the heating pipe. 
     
     
         10 . The heating appliance structure according to  claim 1 , further including a heat flow conduit uprightly connected to the heat-isolating portion and communicating with the heating area, wherein along a longitudinal direction the heat flow conduit does not overlap the heating pipe.
