Shell 4 of the present utility model is a stainless steel casing, has a form 81 on the described pot cover, and this form mainly makes things convenient for user's visual effect, can be the very clear very natural reaction that is interrupted when seeing in the pot each clearly.Form 81 just can make grease and sewage discharge smoothly for being obliquely installed, and keeps the limpid of form for a long time.Be provided with fried basket 23 in the oil cauldron 7, be provided with a plastic rubber bracket 6 between described shell 4 and oil cauldron 7, this plastic rubber bracket 6 is a Collapsible rack, two rotary arms 22 and a head handle 20.During use when handle when being folded down, fried basket is also vertically fallen thereupon, on the contrary fried basket also rises with the direction of handle when handle is up mentioned, and has formed a vertical angle between them.On described pot cover 8, be provided with sealing ring 11 and flanging 13, can guarantee that lid periphery seals fully, sealing advise 11 and flanging 13 be rubber seal.The high temperature of pot the inside and gas can not have injury to the people with regard to can not exclusively not spilling because of its sealing yet like this.High temperature and gas are just discharged from the special device screen pack of top.In the utility model, also on described pot cover 8, be provided with a detachable screen pack 9.After the utility model was through long the use, screen pack 9 many dirts that amass down and grease just can be disposed after pulling down easily like this.As shown in Figure 3,1 is magnetic support bonnet, and 2 is the magnetic support, and 3 is the magnetic electric wire; 5 is handle casing, can select stainless steel to make; 10 is fryer loam cake handle; Be provided with eyeglass at

pot cover

8,12 is lens supports; 14 is the bottom part of pot cover 8; 16 for being located at the button on the handle 20; 17 is the palm compressing tablet, and 18 is the handle upper casing; 19 is the mobile spring on the handle; 21 are fried basket support.Heater 31 of the present utility model is located at the bottom of the utility model shell, on described heater 31 and the main frame fore shell 30 of the present utility model, also is provided with pcb board and host backplane on described main frame fore shell 30.27 are circuit control face-piece, are provided with power knob 24, temperature knob 25, transparency cover 26 on described circuit control face-piece 27.32 is the electric wire wire casing, and 33 is footing.

As shown in accompanying drawing 4,5: control circuit of the present utility model is mainly by power supply, rectifying and voltage-stabilizing, and central processor CPU, by system control, LED is digital to be shown, temperature sense, and electronic switch, heating part is formed.Voltage is by the AC transformer transformation after inserting civil power, and rectifying and voltage-stabilizing exports DC12V respectively and DC5V voltage is supplied with relay and CPU, LED, and charactron shows; Central processor CPU adopts PIC16C57 to write the 4.0M crystal oscillation; When CPU obtains a burning voltage from power supply after, send of short duration piping from pulse voltage of 2 seconds of 25 pin output by 4.7K resistance Q12 conducting BELL, expression has been in holding state, lights the charactron demonstration when pressing the POWER key; Can adjust time and temperature respectively when pressing code switch, the code switch left-right rotation can freely be descended the height of adjusted temperature and the length of time; 7,8,9 pin of CPU compared by R30, C5 and the RT sensor time of discharging and recharging, as the RT sensor sensing to temperature when being lower than show value CPU the 6th pin export a low level at once and be added to the Q2B utmost point, this moment, the Q1B utmost point was high level Q1 conducting RELAY closure, and the AC electric current is flowed through RELAY to the work of heater upper heater.

The code switch left-right rotation can freely descend the adjusted temperature, two are drawn with charactron Q5.Q6 multiplexingly, change Q5.Q6 high-low level is shown by CPU the 11st pin-17 foot control system charactron.

Temperature sense RT should adopt unique zigzag stainless steel sensor, direct detection is in oil, guarantee accurately rapid with reaction speed of temperature, RT links to each other with 7 pin and 8 pin of CPU, cause the time speed of 0.1UF capacitor discharge by the change of RT resistance,, realize the break-make of relay J from 6 pin output high-low level by the comparison of CPU, realize the constant of temperature, disconnection of RT sensor or short circuit CPU all can detect and can be shown on the charactron and show by 6 and 7 pin.

Electronic switch mainly is made up of RELAY and diode of 2 triodes; relay J is after obtaining deriving from rectifying and voltage-stabilizing behind the power supply; to be added to Q1, the Q2 relay J of overturning closed and open-minded when CPU 6 pin are exported a high-low level; when the AC electric current relay J of flowing through; the relay J closure; heater 31 electric on, heater is started working, a relay J coil two ends diode in parallel is used for protection and improves relay J sensitivity.Heater is made up of the resistive assembly of 2000W electric heating.

13 pin of CPU insert VDD by 10K resistance and do not insert VDD and realize Fahrenheit and conversion Celsius respectively, make a central processor CPU have two kinds of different specifications.In this circuit, regularly adopt side's examination carrying out count-down of count-down to set, the time one is sent of short duration piping to be interrupted pulse voltage of 2 seconds of output from 25 pin by 4.7K resistance Q12 conducting buzzer, and the expression timing arrives, and charactron shows.
