Abstract
The utility model discloses a heating pipe for an instant water heater, which comprises a heating pipe body and an electric heating layer attached to the outer wall of the heating pipe body, and a high-temperature-resistance insulation layer is covered outside the electric heating layer. The insulation layer arranged outside the electric heating layer realizes the insulation and sound isolation effects, the current friction sound caused by a magnetic filed generated through current movement in the electric heating layer is effectively isolated only through using the simple and low-cost insulation layer structure, and no noise basically exists when the heating pipe body works.
Description
Technical field
The utility model relates to immediately heating water heater, especially the heat-generating pipe of immediately heating water heater.
Background technology
Immediately heating water heater adopts and in a less enclosure space high-power heater is set, and cold water flows into enclosure space, flows out after the heater heating.Only need the heating of several seconds, the suitable hot water service of temperature just can be arranged, very efficient and convenient, satisfy the allegro living needs of modern at present.
The heat-generating pipe that is applied at present in the immediately heating water heater mainly adopts the quartz glass tube that adheres to conductive layer, be provided with electrode at the body two ends, current pass through in quartz glass tube, whole quartz glass tube just is equivalent to a bare electric conductor, its shortcoming is: use dangerous, the decline of heat-generating pipe power is fast, the heat energy utilization rate is low, the electromagnetic noise that produces in particularly working makes us irritated, general user does not understand the cause of noise, its reason can only be attributed to the electrical equipment sole mass does not pass a test, cause the user to require to return goods to enterprise, enterprise's after-sales service is frequent, not only influence the economic interests of enterprise, the brand names image is suffered damage.
Summary of the invention
Problem to be solved in the utility model just provides a kind of heat-generating pipe of immediately heating water heater, effectively reduces or eliminate the noise that causes because of the current field friction, have simultaneously safe, heat-energy losses is little, the characteristics of long service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of heat-generating pipe of immediately heating water heater, comprise the heating body and attached to the heating tube wall electrothermal layer, it is characterized in that: described electrothermal layer is wrapped with resistant to elevated temperatures insulating barrier.
Further, described insulating barrier is soft insulating barrier, avoids causing magnetic resonance.
Further, described thickness of insulating layer is 1～3mm.
Further, described insulating barrier is to be wrapped in electrothermal layer by insulating tape to form outward.
Further, described insulating barrier is the flexible insulation sleeve pipe that is located on the heating tube wall.
Further, described insulating sleeve adopts heat-shrinkable T bush.Heat-shrinkable T bush has that low temperature shrinks, the function of soft fire-retardant, insulation corrosion protection; Heat-shrinkable T bush be heated after-contraction hold tightly the heating body on, convenient processing and manufacture.
Further, described heating body is a quartz glass tube.
Further, described electrothermal layer is the resistive film attached to the heating tube wall.
The beneficial effects of the utility model:
1, in the prior art for solving the electromagnetic noise problem of immediately heating water heater heat-generating pipe, often adopt sound-absorbing material to coat or the circuit control section of immediately heating water heater improved; Sound-absorbing material is to have stronger absorption acoustic energy, the material of reducing noise performance, but material price is higher; Improvement at the circuit control section has higher professional technique requirement, and actual noise reduction effect is also undesirable.The utility model only utilizes simply and cheaply, and insulation layer structure has just effectively completely cut off the caused electromagnetic noise in magnetic field that produces because of the electric current motion in the electrothermal layer, heat-generating pipe basic noiselessness of when work, good solution the electromagnetic noise problem of immediately heating water heater heat-generating pipe;
2, the heating body that adheres to electrothermal layer itself is equivalent to a bare electric conductor, can improve safety in utilization greatly behind the wrap insulate layer;
3, the electrothermal layer on the existing heating body directly contacts with extraneous air, and thermal loss is big, significantly reduces the loss of heat behind the wrap insulate layer, has improved the electric heating utilance, has improved the efficiency of heating surface of immediately heating water heater heating arrangements to a certain extent;
4, the power attenuation that can slow down heat-generating pipe behind the wrap insulate layer prolongs its useful life.
Description of drawings
Fig. 1 is the structural representation of immediately heating water heater heating arrangements;
Fig. 2 is a structural representation of the present utility model;
Fig. 3 is the A-A profile of Fig. 2.
Embodiment
With reference to Fig. 1, existing immediately heating water heater heating arrangements mainly comprise water-supply line plate 1, sewer plate 2 and be inserted into water-supply line plate 1 and sewer plate 2 between some heat-generating pipes, heating body 3 outer walls adhere to electrothermal layer 31, heating body 3 is a quartz glass tube, this electrothermal layer 31 is attached to the resistive film on heating body 3 outer walls, the so-called forms such as generally being meant high temperature sintering, normal temperature are smeared, printed, plating of adhering to; Two ends at heating body 3 are provided with electrode 32, cold water in heating body 3 by the time absorb heat and become hot water.It more than is the prior art scheme, during heat-generating pipe work, irritated electric current grating was made us in generation when the electric current motion caused generating heat body 3 work in the electrothermal layer 31, and present solution mainly is the circuit control section at heating arrangements, cost height not only, and actual effect is undesirable.
With reference to Fig. 2,3, preferred version of the present utility model is: wrap up the resistant to elevated temperatures insulating barrier 4 of 1～3mm on the electrothermal layer 31 of original heating body 3 again, this insulating barrier 4 is soft insulating barrier 4, avoids causing magnetic resonance; This insulating barrier 4 can be that to be wrapped in electrothermal layer 31 by insulating tape outer and form, and also can adopt the flexible insulation sleeve pipe, and the flexible insulation sleeve pipe generally adopts heat-shrinkable T bush, and heat-shrinkable T bush has that low temperature shrinks, the function of soft fire-retardant, insulation corrosion protection; The heat-shrinkable T bush after-contraction of being heated is held tightly on heating body 3, convenient processing and manufacture, use lighter, heat gun or spray gun all can, compare the insulating tape winding arrangement, use heat-shrinkable T bush not only convenient, and insulation, soundproof effect are better.
In addition, meaning of the present utility model not only is to eliminate current noise, behind the external wrap insulate layer of heat-generating pipe, the safety in utilization of heat-generating pipe is improved greatly, reduce simultaneously heat loss, improved the electric heating utilance, this is exactly the efficiency of heating surface that improves the immediately heating water heater heating arrangements to a certain extent, and the power attenuation that can slow down heat-generating pipe behind the wrap insulate layer, prolong its useful life.
