Abstract
The utility model relates to an electric heater, which comprises an electro-thermal converting element which is formed by coating a basal body with insulation material of quartz, glass, ceramics, mica, etc. with a metal oxide electric heating film. The basal body forms a tubular shape or a banding shape, and both ends of the basal body are made into electrodes using conductive adhesive. The electrode is fixed onto a metal bus-bar, and the bus-bar is connected with a power source. Each electrothermal film thermal conversion element forms a shunt circuit after switching on, and then heat is given out. The electric heating appliance has the advantages of high electric heating conversion efficiency, uniform radiation, no flame and long service life, and the utility model is ideal heating equipment for modern families, offices, hotels, etc.
Description
The utility model relates to a kind of electric heater, and particularly a kind of is the electric heater of electrothermal conversioning element with the Electric radiant Heating Film thermal element.
Traditional electrically heated warmer all adopts heating wire as heating element heater.This electrothermal conversioning element exists the life-span short, naked light is arranged, the low shortcomings such as (being generally 60%) of electric conversion efficiency.For the oil immersed type electric heater, though can eliminate naked light, improve the thermal efficiency to a certain extent, but it is big volume to occur, cost is than problems such as height.
The purpose of this utility model is to develop a kind of Electric radiant Heating Film electric heater, and it is long that it should have the life-span, the thermal conversion efficiency height, and volume is little, and characteristics such as the flames of anger are convenient to make.
Technical solution of the present utility model is: a kind of Electric radiant Heating Film electric heater, it is by electrothermal conversioning element, control circuit system and shell are formed, feature of the present utility model is that this electrothermal conversioning element is to be matrix with tubulose or slab insulant, be coated with the metal oxide Electric radiant Heating Film on it, and make electrode at the matrix two ends with conducting resinl and constitute.
The insulating materials matrix can be quartz, glass, pottery or mica.
The length of every tubulose electrothermal conversioning element is 20～40cm, and external diameter is 8～15mm, and power is 50～400W.
The length of each tabular electrothermal conversioning element is 10～40cm, and width is 1～10cm, and power is 50～400W.
The metal oxide Electric radiant Heating Film is the tin ash semiconductor thermoelectric film.
Every electric heater heating system can be assembled 4～20 of Electric radiant Heating Film thermal conversion elements.The electrode area of each element is separately fixed on two busbars, and busbar connects with power supply, and each Electric radiant Heating Film thermal element of energising back constitutes the shunt circuit and generates heat, and also can need adopt the controllable silicon diode to regulate power by temperature adjustment.
Control circuit of the present utility model system is divided into two and joint groups with the Electric radiant Heating Film thermal element, and each and joint group indicator lamp in parallel are controlled by switch.
Shell of the present utility model is made through punching press and welding processing with sheet metal.Front and back and both sides stamp out the shutter shape or the bar shaped heat radiation crack of right quantity.The bottom is equipped with two pairs of universal wheels, so that move, perhaps is equipped with four supporting legs.
Effect of the present utility model is, by the Electric radiant Heating Film electrothermal conversioning element, the Electric radiant Heating Film electric heater that control circuit system and shell are formed, owing to adopted the Electric radiant Heating Film electrothermal conversioning element, improve electric conversion efficiency, prolonged service life, eliminated naked light, and volume is reduced, be convenient to daily use.
