Abstract
The utility model discloses a heating pipe for an electric water heater, which comprises a first straight pipe, a second straight pipe, a first bent pipe, a second bent pipe, a third straight pipe, a fourth straight pipe and a spiral part, wherein the spiral part comprises a first spiral pipe and a second spiral pipe, one end of the first spiral pipe is connected with one end of the second spiral pipe, the first spiral pipe and the second spiral pipe are arranged in parallel; the other end of the first spiral pipe is respectively connected with the third straight pipe, the first bent pipe and the first straight pipe; the other end of the second spiral pipe is respectively connected with the fourth straight pipe, the second bent pipe and the second straight pipe; the third straight pipe and the fourth straight pipe are in parallel, the first bent pipe and the second bent pipe are in parallel, and the first straight pipe and the second straight pipe are in parallel. The heating pipe is simple in structure, extremely convenient to process and not high on accuracy requirement of a mould, and greatly reduces the defective rate.
Description
Technical field
The utility model relates to a kind of electric heater and uses heating tube.
Background technology
At present; Heating tube that electric heater uses is general to be adopted the heating body of a populated magnesia powder to carry out one enclose and be bent to form, and very high to the requirement of body spacing, and needs the very high bending die of precision to accomplish; In addition; Because heating tube need be crooked through repeatedly, be prone to cause the loose and resistance wire fracture of electrothermal tube magnesium powder, fraction defective is high.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of electric heater to use heating tube, and this heating-pipe structure is simple, processing and convenient, and less demanding to mould and die accuracy, fraction defective reduces greatly.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of electric heater is used heating tube; Said heating tube comprises first straight tube, second straight tube, first bend pipe, second bend pipe, the 3rd straight tube, the 4th straight tube and spire; Said spire comprises first helix tube and second helix tube; Said first helix tube is connected with second helix tube, one end, and this first and second helix tube is arranged in parallel; The other end of said first helix tube connects the 3rd straight tube, first bend pipe and first straight tube respectively; The other end of said second helix tube connects the 4th straight tube, second bend pipe and second straight tube respectively; And said the 3rd straight tube is parallel with the 4th straight tube; Said first bend pipe is parallel with second bend pipe, and said first straight tube is parallel with second straight tube.
Preferably, said first and second bend is " S " type.
Further improvement as the utility model is filled with magnesia powder in said heating tube.
Further improvement as the utility model is provided with resistance wire in said heating tube.
As the further improvement of the utility model, be provided with terminal and eduction rod away from a port of said first and second bend at said first and second straight tube.
Preferably, said heating tube is formed as one.
The beneficial effect of the utility model is: this heating tube adopts the double spiral tube structure, and it is not only simple in structure, and easy to make, and less demanding to mould and die accuracy, can effectively avoid the generation of fraction defective, thereby enhance productivity.
