Technical Field
The invention relates to the technical field of electric heating tubes, in particular to an electric heating tube structure with spiral water inlet.
Background
The spiral water pipe on the market at present has a structure shown in fig. 1, and an electric heating tube 1 and a spiral water pipe 2 are connected by welding. The defects are as follows: 1. the heat is transmitted to the pipe wall of the spiral water pipe 2 through the electric heating pipe 1 and then transmitted to the water; therefore, this structure is inefficient in heat transfer. 2. The problem of scale blockage of the spiral water pipe 2 often occurs during heating, and because the electric heating pipe 1 and the spiral water pipe 2 are welded, the welding temperature is too high; therefore, a method of preventing scale by surface treatment such as teflon spray cannot be used.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a spiral water inlet electric heating tube structure.
The object of the present invention is achieved by the following technical means. A spiral water inlet electric heating tube structure mainly comprises an electric heating tube and a spiral water pipe, wherein the electric heating tube comprises a leading-out rod, a pipe body, magnesium oxide powder and a resistance wire; the water pipe body is sleeved on the pipe body, the surface of the pipe body is provided with an anti-scaling coating, and water in the spiral groove is in direct contact with the surface of the pipe body.
The water pipe body be integrated into one piece structure, perhaps the water pipe body include water pipe body A and water pipe body B, it has half helicla flute to open on water pipe body A and the water pipe body B, forms the helicla flute after water pipe body A and water pipe body B amalgamate together.
The water pipe body is provided with a temperature control device, or the temperature control device is arranged in the electric heating pipe.
The invention has the beneficial effects that: after the structure of the invention is adopted, the surface treatment modes of Teflon and the like can be sprayed on the surface of the electric heating tube to prevent scale deposition, thus solving the problem of scale deposition.

Description of reference numerals: the electric heating tube comprises an electric heating tube 1, a leading-out rod 1-1, a tube body 1-2, magnesium oxide powder 1-3, a resistance wire 1-4, a spiral water tube 2, a spiral groove 2-1, a water tube body 2-2, a water tube body A2-3, a water tube body B2-4, a water inlet tube 3 and a water outlet tube 4.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
example 1: as shown in figures 2-6, the spiral water inlet electric heating pipe structure mainly comprises an electric heating pipe 1 and a spiral water pipe 2, wherein the electric heating pipe 1 comprises a leading-out rod 1-1, a pipe body 1-2, magnesium oxide powder 1-3 and a resistance wire 1-4, the spiral water pipe 2 mainly comprises a cylindrical water pipe body 2-2, and the water pipe body 2-2 is of an integrally formed structure and is manufactured by adopting methods such as water expansion forming and 3D printing. The inner wall of the water pipe body 2-2 is provided with a spiral groove 2-1, and two ends of the water pipe body 2-2 are respectively communicated with a water inlet pipe 3 and a water outlet pipe 4; the water pipe body 2-2 is sleeved on the pipe body 1-2, the surface of the pipe body 1-2 is provided with an anti-scaling coating, and water in the spiral groove 2-1 is directly contacted with the surface of the pipe body 1-2.
The spiral water pipe 2 is assembled with the electric heating pipe 1 in an integral structure, clearance fit is achieved, the phenomenon that a clearance cannot be avoided, and when heating is conducted, the electric heating pipe generates heat and expands, and the spiral water pipe needs interference fit. The spiral water pipe 2 can be integrally structured, a temperature controller and a fuse isothermal control device can be arranged on the water pipe body 2-2, and a temperature control device can be arranged in the electrothermal pipe 1, so that the installation of the temperature control device on the water pipe is simpler. Water enters the spiral groove 2-1 from the water inlet pipe 3, heat is transferred to the spiral water pipe 2 through the electric heating pipe 1, the integrated structure heats water, the temperature control device controls temperature in a dry heating mode, and water is discharged from the water outlet pipe 4.
Example 2: as shown in fig. 7 to 8, the difference from embodiment 1 is that: the water pipe body 2-2 comprises two stamping parts, namely a water pipe body A2-3 and a water pipe body B2-4, wherein the water pipe body A2-3 and the water pipe body B2-4 are provided with half spiral grooves, and the water pipe body A2-3 and the water pipe body B2-4 are spliced together through welding to form the spiral groove 2-1.
