Description
Technical field
What the present invention relates to is a kind of household electric blower, and particularly a kind of high electrothermal efficiency hair dryer that has the ceramic metal oxide thin film heater belongs to household electrical appliance and electric-heating technology field.
Background technology
Electric heater on the common household electric blower is to be made of the nichrome resistance heating wire, this heating element heater and technology exist unsurmountable shortcoming, the heater element resistance silk, oxidation takes place and ruptures in meeting after a period of time is used in energising, and in use can be red-hot luminous.The approach of heating mainly is by this approach of thermal convection current heat exchange, and the efficient that electric heating transforms is not high.This technology is widely used on mostly traditional electric heater product, find by literature search, Fred M.Slingo is in U.S.'s patent of invention of application in 2002, patent name is: Hair dryer employing far-infrared radiation, (using the dry hair dryer of hair of far infrared radiation), number of patent application is: 6,378,225, this patent has adopted a kind of ceramic body of loose structure of pane minor, this ceramic body is placed in this hair dryer body, near the gas transmission exit.Ceramic body generates heat after the air heat by electrical heating wire heating, and the heat that sends is to be that 1.0 μ m～25 μ m infrared lights are main by optical wavelength.It is obvious especially that this infrared band adds thermal effect.The not high problem of efficient that the electric heating of original so traditional electrical heating hair dryer transforms makes moderate progress.But what this patent still adopted is the resistance wire heating, the shortcoming that still unresolved service life is short.
Summary of the invention
The present invention is directed to the defective and the deficiency of existing household electric blower product technology, having proposed a kind of transparent conductive metal oxide ceramic membrane that adopts is the ceramic membrane heater hair dryer of the high electrothermal efficiency of heater element, makes it overcome deficiency in existing household electric blower product and the technology.
The present invention is achieved by the following technical solutions, hair dryer integral body of the present invention is divided into body and handle two parts, be filled with heat-barrier material in the wall around the body, body has an air inlet and air outlet, electric fan is fixed in the body, near the air inlet place, its effect is to force to drive air to enter air inlet, and force air in body, to flow, blow out from air outlet at last, be fixed with the electric heater that inside and outside wall is coated with the transparent conductive metal oxide ceramic membrane between electric fan and air outlet, handle is provided with power switch, the external power supply input port includes power line in the handle.
Electric heater comprises two or more tubular earthenware electric heaters, tubular earthenware electric heater is the cylinder earthenware that inside and outside wall is coated with transparent conductive metal oxide ceramic membrane coating, the thickness of control metal-oxide film makes the metal-oxide film thickness of each tubular earthenware electric heater suitable when preparation transparent conductive metal oxide ceramic membrane, can guarantee in the face heating power density of each tubular earthenware electric heater suitable.Because electrical power and radius are in direct ratio on each tubular earthenware electric heater, and the last external surface area of tube is inversely proportional with radius.
Since silica and aluminium oxide ceramics when being heated, can launch add thermal effect especially significantly, have an infrared light that wavelength is 1.0 μ m～25 μ m.During this infra-red radiation wave band belongs to, far infrared.Use this ceramic material to make drum as base material, again at its surface-coated layer of metal oxide conducting ceramic membrane, constitute the tubular ceramic electric heater, after the energising, the transparent conductive metal oxide ceramic membrane is heating earlier, to cylindric ceramic base material heating, cylindric pottery is launched infrared ray again, to heating through near the air it, heated gas carries out the air outlet that forced convertion blows out hair dryer by fan, can improve the conversion efficiency of electric heating so significantly.
The transparent conductive metal oxide ceramic membrane is the heating coating, and transparent conductive metal oxide ceramic membrane commonly used adopts indium tin oxide or doping stannic oxide film.Spray metal oxidic transparent conductivity ceramics film adopts ultrasonic atomizatio spraying chemical vapor deposition transparent conductive film technology, the heavy knot technology of preferable alloy oxidic transparent conductive film, and this technology can guarantee the uniformity of rete.Transparent conductive metal oxide ceramic membrane thickness is 200～2000nm, usually used material is indium tin oxide or doping stannic oxide film, square resistance on the electricity of this coating can be regulated within a large range, usually, decide the value of square resistance according to needed heating power, as 20 Ω/.The spraying coating process of transparent conductive metal oxide film needs 400 ℃～600 ℃ usually.
The two ends of each tubular earthenware electric heater sinter metallized electrode into silver slurry sintering process, with silver soldering it are connected in parallel each other, use silver soldering, source of welding current line on the conductive paste electrode again.
The two ends of tubular earthenware electric heater are fixing with pottery disc holder (), (two), and two pottery disc holders are fixed in the body.Pottery disc holder (one) (two) is made of pottery, all comprises two annulus, and four potsherds that two annulus are linked together, and is carved with groove respectively on two annulus, and tubular earthenware electric heater inserts groove and fixes; The conductive silver slurry printing of the bottom of groove constitutes the short circuit cross-line between groove with conductive silver slurry, with the high temperature sintering that metallizes.Two pottery disc holder differences are, fixedly pottery disc holder () as the close air outlet of heating film element substrate is the ceramic body with honeycomb porous structure, being shaped as of each honeycomb hole round or polygonal (as positive four limit types), the heat by honeycomb porous structure wherein to fixing pottery disc holder efficiently, heating fully.
The present invention has substantive distinguishing features and marked improvement, and the present invention causes the heating technology with efficient oxidation thing thin-film electro and combines with high-efficiency ceramic infrared light lift-off technology, successfully overcomes the shortcoming in the background technology.The present invention adopts film as heating element heater, being about to the transparent conductive metal oxide ceramic membrane is deposited on the non-conductive ceramic substrate surface, conductive film is that the electrical heating power surface density of technology of heating unit is low, the surface area that contacts with media is big, make this heating unit fully to dispel the heat, belong to the far infrared radiation heat radiation.So the present invention flows through to heating and the air on contact membrane surface is very effective.Safe and reliable, there is not the red-hot part of high temperature, anticorrosive.Limited and in use can be red-hot luminous with the method heating area of resistance wire heating element, not high with the efficient of sending a telegraph heating, the height of heating efficiency is to launch the share of infrared phonon and determined by being converted into the lattice excited vibration in the gross energy, the transparent conductive metal oxide ceramic membrane as the wavelength of the overwhelming majority of the infrared phonon of pyrotoxin emission in 2～20 micron dimension scopes, the heating wave band that this is best just.
