Description

Sectional heater

Technical Field

The utility model belongs to an electric heating pipe, a sectional heater.

Background

At present, most of domestic electric heating equipment is designed by adopting electric heating rods with uniformly distributed temperatures, the design cannot meet the control of a non-heating area, so that redundant heat is generated, the requirements on the temperatures of different areas are different, and the electric heating equipment cannot be effectively heated, so that the energy consumption is increased. Refer to utility model patent CN 204145780U.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to the problem that exists among the prior art, a sectional heater is provided.

For solving the problem that exists among the prior art, the utility model discloses a realize through following technical scheme:

the sectional heater comprises a heating tube shell, wherein a heating wire is arranged in the heating tube shell, and two ends of the heating tube shell are provided with leading-out rods; two ends of the heating wire are connected with the leading-out rod, and insulating materials are filled between the heating tube shell and the heating wire; the inner wall of the heating tube shell is provided with an insulating layer, the heating wire is divided into a plurality of sections, each section of heating wire is wound into a spiral shape, and the plurality of sections of heating wires are connected in series through the connecting rod and are finally connected to the leading-out rod.

As an improvement, each section of heating wire has different winding density and length.

As an improvement, the port of the heating pipe shell is provided with a sealing layer and an insulating bead.

The utility model discloses well connective bar can adopt the structure of drawing forth the stick, does not need the position of heating in arranging the connective bar in the heating pipe body, and heater heating in-process connective bar itself does not generate heat, reduction energy consumption that can furthest.

Compared with the prior art, the beneficial effects of the utility model are that:

the sectional heating structure is adopted to realize different temperatures of different areas of the integral heating pipe, the defrosting efficiency is ensured to be consistent with that of the prior heating pipe while the integral energy consumption is reduced, the temperature of the heating pipe is fully utilized to achieve the optimal defrosting effect, the energy is saved, the same defrosting effect as the prior design can be achieved, the latest standard requirement that the surface temperature of the heating pipe is lower than 360 ℃ is met, and the heating pipe is fully heated only in the area needing to be heated.

FIG. 2 is a schematic view of the structure of the heating tube of the present invention;

fig. 3 is a schematic view of the U-shaped structure of the heating pipe of the present invention.

The attached drawings are as follows: 1-heating tube shell, 2-heating wire, 3-leading-out rod, 4-connecting rod, 5-insulating layer, 6-sealing layer and 7-insulating bead.

Detailed Description

The present invention will be described in detail below with reference to specific embodiments with reference to the attached drawings.

Referring to fig. 1 and 2, a sectional heater includes a heating tube housing 1, a heating wire 2 disposed in the heating tube housing 1, and a drawing rod 3 disposed at two ends of the heating tube housing 1. The end of the heating tube shell 1 is provided with a sealing layer 6 and an insulating bead 7. Two ends of the heating wire 2 are connected with the leading-out rod 3, and insulating materials are filled between the heating tube shell 1 and the heating wire 2; the inner wall of the heating tube shell 1 is provided with an insulating layer 5, the heating wire 2 is divided into a plurality of sections, each section of heating wire 2 is wound into a spiral shape, and the plurality of sections of heating wires 2 are connected in series through a connecting rod 4 and finally connected to a leading-out rod 3.

Different density of different lengths of heater 2 are twined through connective bar 4, then twine to drawing forth stick 3, and each section heater 2 can provide different heating temperature. Through setting up the parameter of the heater 2, the connective bar 4 in different heating areas, can make the heating pipe have high temperature control ability, be favorable to the high-efficient work of heating pipe, eliminate unnecessary loss, greatly reduced the energy consumption of heating pipe.

As shown in FIG. 3, the present invention is not limited to straight pipes, and can be used for bent pipes, spiral pipes, etc. The connecting rod in the bending area can ensure that the heating wire is centered, prevent the heating wire from being eccentric, and is very suitable for popularization and use.

Finally, it is to be noted that the above list is only a specific example of the present invention. Obviously, the present invention is not limited to the above embodiments, and many variations are possible. All modifications which can be derived or suggested by a person skilled in the art from the disclosure of the invention should be considered as within the scope of the invention.
