CN202334930U - Electric heating cloth having suspended electrode - Google Patents

Abstract

The utility model provides an electric heating cloth having a suspended electrode. A polymer composite coating having PTC (Positive Temperature Coefficient) is adopted as an electric heating layer. A metal lead, a metal foil or a conductive coating is adopted as the electrode. The electrode and the electric heating layer are separated with a mini pad and are kept in a certain distance, or the electrode and the electric heating layer can be disposed on different layers. When under pressure, the electrode contacts with the electric heating layer closely and the electric heating cloth generates heat quickly. And when under no pressure, the electrode and the electric heating layer separate with each other automatically and currents are cut off. The electric heating cloth having the suspended electrode in the utility model can be used as the electric heating layer of an electric heating blanket, an electric heating cushion, an electric heating waistband, an electric heating kneelet, an electric heating shoe-pad or an electric carpet.

Description

The electric heating cloth that electrode suspends

Technical field: the utility model belongs to the thermo electric material field, specifically belongs to energy-saving electric heating cloth.

Background technology

Electric heating has advantages such as cleaning no discharging, environmental friendliness, investment be little, is a kind of low-carbon (LC) heating system.Though still there is a large amount of carbon emissions in thermal power generation, it is fast-developing that water power, wind-powered electricity generation, solar power generation etc. do not have the discharging new technology, and the discharge capacity of electric energy is reduced day by day.With compared with techniques such as fire coal, combustion gas, the heating mode of the beyond doubt environmental protection of electroheat technology.Convert heat energy to by electric energy multiple mode is arranged: like infrared lamp, heating wire etc.Infrared lamp also can produce visible light when sending infrared light, reduced electric conversion efficiency, and produces light pollution.Produce electromagnetic pollution during the heating wire energising; Conduct heat with cross-ventilated mode by air blast, also can produce dust pollution; The motor of blast apparatus high speed rotating also can produce electromagnetic pollution.Need temperature-adjusting circuit to guarantee user security in addition, cost is higher.

The electrothermal method different with above-mentioned technology is semiconducting polymer's electroheat technology; Semiconducting polymer's material produces heat through electric current the time, all convert electric energy to heat energy, does not produce visible light; Electric conversion efficiency is nearly 100%, is a kind of energy-efficient heating system; Its face heating system is more even than traditional heating mode.Simultaneously, it to the human body heat supply, snugness and efficient are high with the infrared radiation mode.This type electroheat technology such as Electric radiant Heating Film or electric heating cloth have been used for indoor confession heating, electric blanket, electric pad etc.

The present invention is a new technology that on the technological basis of face heating at present, proposes, and method simply but more energy-conservation, safety and intelligence.According to the literature search result that the applicant did, the mode that all so far Electric radiant Heating Film, electric heating cloth all adopt electrode to contact with the electrothermal layer fixing compact.The characteristics of this traditional approach are that the energising rear electrode conducts the current to electrothermal layer immediately; When cutting off the electric current of electrode, also cut off the electric current of electrothermal layer.Therefore need switch and control circuit that control is carried out in the work of electrothermal layer.If an electric heating cloth or film are carried out the heating of regioselectivity, must need a plurality of temperature sensors by plurality of small blocks splicing and subregion control, add temperature control circuit, microcomputer, cost is higher.Different with conventional art is; The present invention is through changing structure; Make electric heating cloth self become pressure sensitive switch, under the situation of not assembly sensor and self controlled element, zones of different is wherein carried out optionally heating; With the implemented with low cost automatic switch with from the dual intelligence of temperature control, to reach energy-conservation and purpose of safety.

Summary of the invention

In order to overcome the high deficiency of electric heating expense, the utility model proposes the electric heating cloth that a kind of electrode suspends.This electric heating cloth can optionally heat as required, is used for the zone of heating of energy saving type electric heating blanket, electric heating ground cushion, electric heating cushion, electric heating shoe-pad, electric heating waistband, electric heating knee protector, electric heat mat, can save electric energy, can also play on-off action.

The technical scheme of the utility model is that the electric heating cloth that the utility model patent electrode suspends is made up of electrothermal layer and electrode.Electrothermal layer is semiconducting polymer's composite material, have ptc characteristics.Used macromolecular material is polyethylene or poly copolymer EVA, VAE or silicon rubber; Active component has graphite, acetylene black, metal oxide and other auxiliary agent; Electrothermal layer by electric-heating coatings coating, be printed onto on the base material and form.Also can pass through mixing, the extrusion molding of raw material.Base material is cloth or polyester film or polyethylene film.Electrode is two groups of parallel maintenance numbers centimetre leads to tens of cm distance, the printed circuit that optional Copper Foil of electrode material or single face copper foil tape or plain conductor (copper cash, stainless steel wire) or electrically-conducting paint form.Each electrode and electrothermal layer keep millimetre-sized distance, can be arranged on the heat-conducting layer top, or be arranged on another aspect.Electrode closely contacted with electro-thermal coatings when this structure was under pressure electric heating cloth, electric current heating rapidly through electro-thermal coatings; Circuit automatic disconnection when pressure solutions is removed is to save electric energy.

The beneficial effect of patent art: 1, save electric energy, 2, automatic switch, 3, simplified structure.
