Embodiment Construction

[0013] From figure 1 It can be seen that the convection tube of the energy-saving kettle connects the inner pot 3 and the outer pot 4, the inner pot 3 includes the inner pot bottom 6, and there are two convection tubes, which are respectively convection tube 1 and convection tube 2, and the distance between convection tube 1 and convection tube 2 is The height at the bottom of the inner pot 6 has a height difference.

[0014] The convection tube 1, the convection tube 2 have a height difference from the height of the inner kettle bottom 6, that is, the distances between the convection tube 1, the convection tube 2 and the inner kettle bottom 6 are not equal. Water has the characteristics of thermal expansion and cold contraction, high-temperature water with light specific gravity and low specific gravity, floating upward, and low-temperature water with large specific gravity and heavy specific gravity to sink. When heating, there is a temperature difference between the water i...

Abstract

The invention discloses a convection tube of an energy-saving kettle. The convection tube connects an inner kettle and an outer kettle, wherein the inner kettle comprises an inner kettle bottom. The convection tube comprises a convection tube (1) and a convection tube (2) which have a difference of the heights to the inner kettle bottom. The invention utilizes the characteristics that water expands with heat and contracts with cold, high-temperature water has light specific gravity and floats upwards, and low-temperature water has heavy specific gravity and sinks downwards to ensure that water in the inner kettle and water in the outer kettle automatically convect and are synchronously heated up through the difference of the heights of the two convection tubes to the inner kettle bottom, has simple structure and convenient processing and ensures that the energy-saving kettle is safe and firm.

Description

technical field [0001] The invention relates to a convection tube of an energy-saving kettle. Background technique [0002] In the Chinese Utility Model Patent Specification whose application number is 94238615.9, a kind of energy-saving kettle is disclosed, which is made up of an outer kettle, an inner kettle and a connecting pipe, and the connecting pipe connects the inner and outer kettles. The heating of the water in the outer pot and the water in the inner pot by the fire is mostly asynchronous. Either the water temperature in the outer pot is higher than the water temperature in the inner pot, or the water temperature in the inner pot is higher than that in the outer pot. Although there are one or more connecting pipes to connect the inner and outer pots of water, since the height of the connecting pipes from the bottom of the pot is the same, the specific gravity of water at the same height is the same, and there is no flow between the inner pot water and the outer po...
