Description

Micro computer seal integral-type electric frying pan
Technical field
Micro computer seal integral-type electric frying pan belongs to domestic electric heating cooker field.
Background technology
Present electric frying pan, mainly contain integral type and split type two kinds, split type i.e. pot, heating temperature control partly constitute, for the ease of cooking, fall dish, clean a pot, general electrical heating temperature control partly is placed in the base, the subject matter that this split type electric frying pan exists is by heat conduction heating, owing to have pot body and electric heating plate contact gap problem, the thermal efficiency is low, and the cooking effect is undesirable, therefore is difficult for being accepted by people.Design the integral type electric frying pan in order to address this problem the someone, mainly constitute,, make because of interior outer pan body is metal material although the integral type electrical heating elements is fixed between interior outer pan body by inside and outside pot body, electric heating tube, inside and outside heat radiation is still very fast, and the thermal efficiency is not high.Through " Chinese patent " retrieval, existing people is in insulation, heat insulation aspect is studied, but still there are many defectives, the applicant is defective and the problem that exists at prior art, comprise the patented product that self designs, as disclosed utility model title in " Chinese patent " on February 23rd, 2000: compound pot body insulation electric frying pan of the multiple end, the applying date: on April 10th, 1999, this compound pot body insulation electric frying pan of the multiple end, comprise: inner pan body 1, electrothermal tube 3, heat-insulation layer 4, outer pan body 5, electrothermal tube 3, outer pan body 5 intervolves at the place, pot edge and is one, have thermal efficiency height, reach more than 90%, advantages such as insulation, but still exist the whole cooker body heavy, face shaping, be incubated not ideal enoughly, temperature control protection is difficult to realize; Removing the problems referred to above external power (duration and degree of heating) adjusting also is that present electric frying pan manufactures and designs comparison stubborn problem in the process.Existing electric frying pan power (duration and degree of heating) is regulated and is mainly contained dual mode: the one, and adopt a plurality of switches to control a plurality of heating element heaters of electric heating plate respectively, by closing or the opening section heating element heater is controlled electric frying pan power, but there is the uneven problem of kettle temperature; The 2nd, adopt the temperature adjustment of temperature control element temperature control, because the particularity of cooking process, a cooking process temperature alters a great deal, to put the dish amount also inequality at every turn, thereby be difficult to reach desirable cooking effect.
Summary of the invention
The technical problems to be solved in the utility model is to overcome existing electric frying pan and have deficiency, the micro computer seal integral-type electric frying pan that provide a kind of pot of light, not water funk, the high-power very hot oven of body, conveniently uses.
The technical scheme that its technical problem that solves the utility model adopts is: micro computer seal integral-type electric frying pan, comprise: frying pan main body 1, microcomputer controller 2, it is characterized in that, frying pan main body 1 is a seal integral-type structure, microcomputer controller 2 places outside the frying pan main body 1, the control signal of microcomputer controller 2 outputs links to each other with the electric heater unit of frying pan main body 1 by the power line that is connected with frying pan main body 1 Top carry handle, external input power supply links to each other with microcomputer controller 2, the electric power feeding time at intermittence of electrical heating elements by the control electric heater unit carries out power (duration and degree of heating) adjustment, and realizes that many grades are regularly adjusted.Micro computer seal integral-type electric frying pan of the present utility model, the course of work and operation principle are: the input plug of microcomputer controller 2 is inserted supply socket, output plug inserts frying pan main body 1 handgrip socket, button 14 is adjusted in the timing of adjusting on microcomputer controller 2 panels, initial default is 15 minutes, corresponding LED light is bright to be shown, the duration and degree of heating of adjusting again on microcomputer controller 2 panels is adjusted button 13, corresponding LED light is bright to be shown, then by releasing the button the electric heating tube RF of frying pan main body 1 inside 1-RF 3Pot body 3 is heated, can adjust the size of the cooking duration and degree of heating in the cooking process as requested at any time again, microcomputer controller 2 is according to the duration and degree of heating signal controlling electric heating tube RF that is imported 1-RF 3The electric power feeding time at intermittence, thereby carry out power adjustment and duration and degree of heating adjustment.Timing means by the back microcomputer controller 2 of releasing the button picks up counting, increase along with the frying pan working time, LED light is bright accordingly on microcomputer controller 2 panels extinguishes one by one, up to turning off the frying pan power supply automatically, can readjust the time again if will continue cooking.
The beneficial effects of the utility model are: microcomputerized control realizes that many grades are regularly adjusted and many grades of mean power adjustment of 350W--2100W, and power is easy to adjust reliable, homogeneous heating; Adopt frying pan pot body and electric heater unit integral structure simultaneously, be equipped with temperature controller and heat-insulation layer below the electric heater unit, both solved prior art pot body heaviness, be incubated dissatisfactory problem, increased the temperature control defencive function again, external seal is equipped with the integral type plastic casing, makes good looking appearance; External owing to microcomputer controller simultaneously, thereby electric frying pan has high-power very hot oven, dish, the waterproof characteristics that clean a pot are fallen in the pot cooking of running, the convenient use.The insulation material that is provided with had both made the heat of pot body not distribute preferably, can guarantee that again plastic casing is indeformable.Thereby the electric frying pan main body light, attractive in appearance, clean a pot not water funk, the convenient use.
