Microwave is a kind of electromagnetic wave, and frequency range is 300MHz~300GHz.Household microwave oven generally adopts the operating frequency of 2450MHz, when field intensity reaches certain intensity, will make the violent friction of polar water molecules and the generation heat, and the object temperature that microwave is acted on raises, and reaches the purpose of cooking food.Also dry moisture material with microwave in the industry, as Chinese medicine medicinal material, pill according to this principle.
The someone proposes the imagination of coming drying clothes, making domestic microwave clothes drying machine with microwave successively in recent years, some patent applications (as application number being: 01128307.6,00122106.x, 02244108.5,01280465.7,00204206.1,98231217.2,95217354.9,95237847.7 application for a patent for invention and utility model patent) have also appearred, but up to now, do not see that as yet any domestic microwave clothes drying machine appears on the market.
Analyze its reason, mainly be:
Launch products and penetration and promotion except that production technology is feasible, also must have considering of economic angle.The high voltage source that is applied in the household microwave oven is a half-wave voltage doubler, behind the connection alternating current, boosts through band Filament Winding high-tension transformer 5, and positive half cycle charges to electric capacity by kenotron 13, and magnetron is not worked; Negative half period is connected to the magnetron power supply by band Filament Winding high-tension transformer 5 high pressure windings and capacitor, magnetron work, output microwave.Fig. 1 is the schematic diagram of half-wave voltage doubler, and Fig. 2 is the ac power waveform figure of half-wave voltage doubler, and Fig. 3 is a magnetron sun step voltage oscillogram in the half-wave voltage doubler, and Fig. 4 is the microwave output power oscillogram of half-wave voltage doubler.Adopt the power supply of this open-and-shut circuit, cost is low, and effect is good, is therefore generally adopted by household microwave oven.Taking cost into account, domestic microwave clothes drying machine need adopt the power supply identical with household microwave oven.But in principle, this low-cost power supply is a kind of broad pulse power supply, and the pulse microwave power output will be higher than mean power more than one times, that is to say, 800 watts micro-wave oven is meant 800 watts of mean powers, and pulse peak power is actual to reach 1700 watts.This working method does not have the influence of significant adverse to heated food, so can be applicable to micro-wave oven; But in drying clothes, this will cause the clothing part to burn out, if clothing also will produce tangible spark phenomenon with metallic article (as metal zip fastener, Metal buttons, metal decoration).Prior art does not address this problem.
In addition, mostly the existing design of microwave clothes drier is only to have adopted a microwave oven magnetic, and its microwave average power density is lower, and drying time is longer, dries inhomogeneously, and drying effect is bad; Individual program (be as application number 95217354.9 utility model patent) has adopted two microwave oven magnetic even many magnetrons combinations in the same way, because previous reasons, this will make the microwave pulse power peak value higher, and it is more serious to strike sparks, more serious to the damage of clothing.
In view of the defective or the deficiency of prior art, present patent application has proposed the design of new microwave clothes drier on a large amount of experimental basis.
Summary of the invention
The present invention is primarily aimed at the deficiencies in the prior art, circuit by transforming household microwave oven magnetron high voltage source, orthogonal microwave is set intensifies direction, adopt polygon cabinet or technological means such as cylindrical or drum-type reaction chamber, provide that a kind of microwave peak power density is low, average power density is higher, oven dry is even, drying time is shorter, can not burn out normal laundry, can not metallic spark phenomenon, and the design of low, the practical domestic microwave clothes drying machine of cost.
The existing design of microwave clothes drier has substantially all comprised structural framing, shell, cabinet door, reaction chamber, magnetron, excitation cavity, excitation cavity waveguide mouth, dehumidifier exhaust blower, and control device.In some scheme, magnetron and excitation cavity are positioned at the reaction chamber side, and in other schemes, magnetron and excitation cavity are positioned on the reaction chamber top.
Because cost reason, microwave clothes drier need adopt the magnetron that is widely used in the household microwave oven, but just as mentioned before, this will burn out clothing in the clothing drying course, and make metallic article accompanying on the clothing produce spark phenomenon, therefore, the present invention transforms the circuit of magnetron high voltage source.
The high-voltage power circuit of conventional microwave oven is a half-wave voltage doubler, the present invention transform it as contain power adjustment apparatus full-wave rectifying circuit, its working method is: the 220V AC power is divided into two-way, and one the tunnel is added on the filament transformer 15, is the magnetron heater power supply; Another road is added to high-tension transformer 11, boosts to about 4200V through high-tension transformer 11, and 4200V voltage is through behind the high-voltage capacitor 12, and piling 22 rectifications by the high-voltage rectifying bridge is the all-wave pulse dc high voltage, again by reactor filtering, for magnetron work.When alternating current was positive half cycle, high-tension transformer 11 output windings upper end was for just, and electric current to ground, passes through choke coil 20, magnetron 14, high-voltage diode C18 by high-voltage capacitor 12, high-voltage diode A16 again, gets back to high-tension transformer 11 and exports the winding lower ends; When alternating current was negative half period, high-tension transformer 11 output winding lower ends were for just, and electric current to ground, passes through choke coil 20, magnetron 14, high-voltage diode D19 by high-voltage capacitor 12, high-voltage diode B17 again, gets back on the high-tension transformer 11 output windings.At above-mentioned alternating current is that high-voltage dc voltage can both reach the rated operational voltage of magnetron, makes the magnetron operate as normal under two kinds of situations of positive and negative half cycle, the output microwave.Because alternating voltage is sinusoidal wave, if adopt half-wave rectifying circuit just can only utilize the half period of power supply, power output is discontinuous; And full-wave rectifying circuit can make the positive half cycle of power supply and negative half period all can be utilized, and makes power output continuous, and reduces the microwave pulse power peak value.
