Abstract

The utility model relates to a novel microwave clothes dryer; a resonant cavity is enclosed from three round platforms and is similar to an ellipsoidal combined hollow cavity; and three magnetron feed ports arranged on the resonant cavity are designed into certain degrees and form identification directions which are mutually vertical. The design is characterized in that the average microwave power density in the resonant cavity is quite high and the peak power density is quite low; when the load is quite large, two spherical energy-rich regions with quite large sizes are arranged in a vertical direction; and the positions of the spherical energy-rich regions comply with the lining positions of suspended clothing, and energy is enriched in a cavity edge transition area. When the load is very small, excessive energy is reflected or absorbed by a stove wall so that an antenna cap is not ignited. Simultaneously, three single delay relays are used for respectively controlling three magnetrons, and a double-delay relay is used for controlling a lumped circuit. When in drying, the three magnetrons are adopted for supplying heat simultaneously by means of interrupted and sequential closing, stopping and the like, can be freely combined and set on a panel according to the number of wet and dry levels according to clothing dried at one step, control the microwave heating time intervals through the double-delay relay, thereby ensuring that the load temperature can be maintained appropriate and preventing the phenomena of clothing overheat and body dry-burning.

Description

A kind of novel microwave dryer

Technical field:

The utility model relates to the mechanical device that utilizes the microwave energy dried material, especially adopts the dryer of heating using microwave.

Background technology:

Can realize during microwave clothes drying being heated internally, the rate of drying height, quality is good, and the effect of cold sterilization is arranged, but microwave is to accept electric energy by magnetron to produce microwave power, a kind of high frequency that radiate by waveguide then, when being used for drying machine, the structure of hothouse, radiation length, the direction of waveguide emission and radiation space structure have a significant impact the utilization of drying effect and energy.The mechanical device that utilizes the microwave energy dried material that can see on the market at present, especially the common shortcoming of microwave clothes drier is, microwave energy skewness in the microwave cavity, there is the highdensity peak region of radiant energy, not only clothing is heated inhomogeneous, influence the clothing quality, and spark phenomenon can occur when running into highdensity peak region, energy consumption height and rate of drying is low such as metal objects such as metal buttons when having ordered on the clothing.For example be the relevant patent of some dryers (related application number has: 01128307.6,02244108.5,01280465.7 etc.) of mode of heating with the microwave, the cavity geometry design be simple cube or cylinder.Because the convenience of processing, great majority have adopted cube (as number of patent application 01128307.6).No matter be cylinder or cube, in the resonant cavity when unloaded the S parameter be enriched between 0.88 to 0.96, and all concentrate on first quartile, a large amount of electromagnetic waves are reflected back toward the magnetrons antennae cap place.Less in load, i.e. oven dry is a small amount of, during the smallclothes clothing, can cause the magnetrons antennae cap sparking, and when load was big, electromagnetic field was periodic distribution at carrier surface, and energy is enriched in the narrow and small FX of several volumes, can not realize even heating.

Another shortcoming that adopts the dryer of heating using microwave at present is the top of microwave generator design at drying machine, clothing is suspended in the below of waveguide, the upper end of clothing is nearest apart from the microwave emitter like this, part topmost is inevitable dry earlier, dry speed is to go up soon down slowly, and be suspended in clothing in the hothouse, because the effect of gravity, moisture content but is high down low, so also can cause uneven drying, because most of moisture (away from launch point) position evaporation in the bottom has widened radiation length virtually, certainly will cause the available energy utilization ratio to reduce simultaneously.In order to solve the cloth drying problem of non-uniform, the microwave clothes drier that has is designed to roll form to hothouse, has brought the wrinkling problem of clothing so again.

Summary of the invention:

For solve existing microwave clothes drier energy utilize unreasonable, uneven drying, of poor quality, the energy consumption height, the defective in wrinkling all problems of clothing and the design of radiation space cavity body structure, the present utility model a kind of novel microwave dryer.

The purpose of this utility model is realized by following technical scheme:

The utility model by air blast 1, housing 2, magnetron a3, down courage 4, magnetron b5, resonator 6, gate 7, middle courage 8, go up courage 9, clothes hanger 10, ammeter a11, ammeter b12, rotating disk 13, ammeter c14, steam vent 15, relay a16, relay b17, relay c18, magnetron c19, doorframe 20, panel 21, cabinet rear panel 22, installing hole 23, box side 24, exhausting duct 25, dual-delay relay 26 etc. and constitute, resonator 6 is by courage 4, middle courage 8 down, goes up 9 three round platforms of courage and surround and be similar to axiolitic combination hollow shape chamber.Resonator, air blast, exhaust outlet, electric current Displaying Meter, relay etc. are installed on the panel 21, and magnetron a and magnetron b are installed on the wall of following courage 4 of resonator and alternate certain angle is arranged the top of courage 8 during magnetron c is installed in.Air blast 1 is installed in the bottom of housing 2, steam vent 15 is opened on the top of housing 2, and the end face of housing 2 has the installing hole 23 of the drive motors of rotating disk 13, and rotating disk 13 is installed in the top of courage 9, clothes hanger 10 is articulated on the rotating disk 13, and dry run turntable 13 is subjected to Motor Drive and rotates.

Microwave cavity 6 designs of the present utility model are by following courage 4, middle courage 8, the hollow cavity that 9 three round platforms of last courage surround, and be similar to axiolitic combination shape chamber, this cavity body structure design, radiant energy can not occur and concentrate on a phenomenon on the focus, the distribution of magnetron simultaneously is again that magnetron c19 is installed on last courage 9, magnetron a3 and magnetron b5 are installed on the following courage 4, three magnetron feedback mouths are mutually certain angle, the orthogonal direction that intensifies is set, this design is when load is big, the cavity edge energy is less, in vertical direction two spherical energy enrichment regions that volume is bigger are arranged, its position conforms to the arrangement position of suspention clothing, and the microwave average power density is higher and power peak density is less, does not have the energy enrichment in cavity edge transition zone.When load was very little, excess energy was reflected or absorbs by the furnace wall and can not cause antenna cap to strike sparks.Homogeneous heating, metal sparking risk is low to be one of advantage of this kind cavity design.

In addition, the mode that the utility model heat supply can be taked three magnetrons whiles or be interrupted, closes down is successively controlled three magnetrons respectively with three single time-delay relays, by a dual-delay relay control way circuit.Because in three magnetrons of this design, any two magnetrons combination the phenomenon that energy seriously is enriched in narrow and small zone can not occur, thereby in heating initial stage, higher stage of clothing moisture content, three magnetrons can be opened simultaneously, improves power density.In the heating later stage, along with the clothing moisture reduces, at interval by dual-delay relay control microwave heating time, simultaneously, utilize single time-delay relay that three magnetrons are started successively or close down, the proof load temperature can maintain preference temperature, can avoid the overheated and body dry combustion method phenomenon of clothing.
