The electric heater is characterized in that the outer layer of the rotary clothes drying cage is provided with a circle of air duct inner girth sheet, a plurality circles of double-flow air ducts are distributed on the circumference of the air duct inner girth sheet, the outlet of each double-flow air duct is communicated with an outlet on the air duct inner girth sheet, a layer of arc heating plate is arranged on the outer side of each double-flow air duct, each arc heating plate is provided with an opening communicated with the inlet of each double-flow air duct, a heat insulation layer is fixedly connected on each arc heating plate, an induction coil is arranged on the outer side face of each heat insulation layer, an air duct outer girth sheet is arranged outside the heat insulation layer, and a gap is formed between each heat insulation layer and the air duct outer ring girth sheet. The utility model has the advantages that the heater is heated by induction current with rapid heating and high energy efficiency, the temperature of the heater is uniform temperature and not high (approaching a steam type), thereby the thermal inertia is low and the temperature is easy to control, and the heater has simple structure and is easy to realize.
Description
Technical field
The utility model relates to a kind of electric heater of dryer, particularly a kind of electric heater that adopts electromagnetic induction heating technology.
Background technology
Dryer claims dryer again.The mode of heating of present known dryer mainly contains two kinds of steam and electrical heating.Adopt the dryer of steam heater to have characteristics such as thermal power is big, the easy control of bake out temperature, therefore obtain wider application.But its weak point is, needs the external steam source, and under the background of national environmental protection, low-carbon (LC) policy, has a coal-burning boiler to produce low-cost steam, will more and more become a kind of extravagant hope.Therefore, the vapor heating type dryer will more and more be subjected to the restriction in market.This piece market space has just in time been filled up in the production of electric heating type dryer, yet this electric heater adopts tradition (resistance wire) electrothermal tube heating mostly, has that heating-up temperature is inhomogeneous, thermal inertia makes shortcomings such as temperature control difficulty greatly.Therefore, demand inventing a kind of novel dryer electric heater urgently.
Summary of the invention
The purpose of this utility model is to solve the existing the problems referred to above of dryer traditional electrical heat pipe heater of the prior art, a kind of dryer electric heater that adopts electromagnetic induction heating technology is provided, a kind of dryer electric heater that adopts electromagnetic induction heater of the utility model design, comprise dryer, the drying rotating cage, it is characterized in that: the skin of drying rotating cage has girth sheets in the circle air channel, circle distribution along girth sheets in the air channel has the double-current Cheng Fengdao of some circles, the outlet of double fluid Cheng Fengdao is communicated with the opening on the girth sheets in the air channel, in the double-current Cheng Fengdao outside one deck arc heating plate is arranged, the inlet that open communication double fluid Cheng Fengdao is arranged on the arc heating plate, on the arc heating plate, be fixedly connected with one deck heat-insulation layer, on the heat-insulation layer lateral surface, induction coil is installed, in the heat-insulation layer outside girth sheets outside the air channel is arranged, outside heat-insulation layer and air channel, between the girth sheets space is arranged.It is characterized in that: double-current Cheng Fengdao is made up of two folded mutually air channels, is connected at two air channel ends, at two air channel head ends outlet and inlet is arranged.The utility model has the advantages that heater is heated by induced-current, heating is rapid, energy efficiency is high; Even and the temperature not high (near steam type) of heter temperature, so thermal inertia is little, easy control of temperature; Heater structure is simple, realizes easily.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the left view of the utility model Fig. 1,
Fig. 3 is the partial enlarged drawing at Fig. 2 II place.
Below in conjunction with drawings and Examples the utility model is elaborated,
The specific embodiment
Comprise dryer (not drawing) among the figure, drying rotating cage 7, it is characterized in that: the skin of drying rotating cage 7 has girth sheets 4 in the circle air channel, circle distribution along girth sheets in the air channel 4 has the double-current Cheng Fengdao 6 of some circles, the outlet 8 of double fluid Cheng Fengdao 6 is communicated with the opening 11 on the girth sheets 4 in the air channel, in double-current Cheng Fengdao 6 outsides one deck arc heating plate 3 is arranged, there is opening 9 to be communicated with the inlet 10 of double-current Cheng Fengdao 6 on the arc heating plate 3, on arc heating plate 3, be fixedly connected with one deck heat-insulation layer 2, on heat-insulation layer 2 lateral surfaces, induction coil 1 is installed, in heat-insulation layer 2 outsides girth sheets 5 outside the air channel is arranged, outside heat-insulation layer 2 and air channel, between the girth sheets 5 space is arranged.It is characterized in that: double-current Cheng Fengdao 6 is made up of two folded mutually air channels, is connected at two air channel ends, at two air channel head ends outlet 8 and inlet 10 is arranged.During work, the space of air-flow (under the effect of blower fan (not drawing)) outside the heater both sides enter heat-insulation layer and air channel between the girth sheets, the i.e. first pass in outer air channel, enter the inlet 10 of double-current Cheng Fengdao again from the opening 9 at arc heating plate top, second flow process in air channel promptly, air-flow obtains heating successively in above-mentioned flowing, temperature progressively improves, and obtains heated air stream and is entered in the surperficial meshed drying rotating cage 7 by the opening 11 on the girth sheets 4 in the outlet 8 connection air channels of double-current Cheng Fengdao.
Place the high frequency electric source in the cabinet power frequency supply can be converted to the high frequency electric source of frequency up to 20-40kHz.Produce high frequency magnetic field when flowing through induction coil 1 from the high frequency electric source electric current, produce the rotatory current (eddy current) of many closures at induction arc lower heating plate 3 walls of high frequency magnetic field, this electric current is (being equivalent to short circuit current) greatly, and embody in the mode of heating.
The utility model has the advantages that heater is heated by induced-current, heating is rapid, energy efficiency is high; Even and the temperature not high (near steam type) of heter temperature, so thermal inertia is little, easy control of temperature; Heater structure is simple, realizes easily.
