The Temperature Control Type multifunctional electric cooker

Technical field

The utility model relates to a kind of Domestic Electric Cooker, particularly a kind of Temperature Control Type multifunctional electric cooker that utilizes amount slow-release and multi-point temp control to boil.

Background technology

Electric cooker is a kind of household electrical appliance of having popularized, and product develops into electron temperature-control from mechanical temperature control, from the development of simple function electric cooker multifunctional electric cooker is arranged, and provides convenience for people boil.Electron temperature-control formula electric cooker has thoroughly changed the temperature control part-structure of electric cooker, utilizes electronic circuit temperature automatically controlled, has optimized the structure and the outward appearance of electric cooker, has expanded regularly function such as boil, cook congee automatically; Along with development in science and technology, the computer electric cooker has appearred again, utilize the control of computer chip and fuzzy technology, further optimized the combination property of electric cooker, improve reliability, the stability of electric cooker work, but increased the complexity of control circuit simultaneously, improved production cost, caused selling price significantly to rise.In order to address these problems, a lot of patents about the electric cooker aspect are arranged, from energy-conservation, function, aspects such as structure propose to improve technical scheme, I am also with regard to the electric cooker structure, electric heater, the application of control device aspect 10 patents, provide a kind of " intelligent temperature control declines and presses electric cooker " as patent 02271742.0, " the ceramic heat conduction electric heater " of patent 20226590.9, " Temperature Control Type intelligent electric cooker " of patent 02226589 or the like, though improving product structure, the aspect that reduces cost obtains effect, but also need further optimize and improve its structure, expanded function.

Summary of the invention

The purpose of this utility model is to provide a kind of improved Temperature Control Type multifunctional electric cooker for the shortcoming that overcomes above-mentioned prior art, utilizes the control of amount slow-release and multi-point temp to improve the quality that boils, and increases the function that boils, and reduces cost.

The purpose of this utility model can realize by following technical measures: this electric cooker has a pot body, the pot courage, pot cover, heat-generating disc, control circuit, the pot courage can adopt boccaro pot courage, heat-generating disc is the ceramic heat conduction electric heater of slowly-releasing heat, be provided with temperature controller with manual reset at control circuit, temperature controller automatically resets, postpone temperature controller, hand switch, the temperature controlling point ratio of the temperature controller with manual reset temperature controller that automatically resets, postpone temperature controller temperature controlling point height, the temperature controlling point that postpones temperature controller compares temperature controller with manual reset, the temperature controller temperature controlling point that automatically resets is low, the reset key of temperature controller with manual reset directly is attached to a pot body sidewall outer surface, directly button resets, hand switch is installed on pot body sidewall outer surface, can directly operate control; Connect with heat-generating disc behind the temperature controller that the automatically resets series connection temperature controller with manual reset, hand switch is provided with low level and off-normal contact, the low level contact of hand switch connects the temperature controller that automatically resets, and the off-normal contact of hand switch connects temperature controller with manual reset, contact between the temperature controller automatically resets.When hand switch was connected the low level contact, the temperature controller that automatically resets was connected with temperature controller with manual reset and is controlled heat-generating disc work; When hand switch is connected off-normal contact, has only the work of temperature controller with manual reset control heat-generating disc.In fact the off-normal contact of hand switch be higher temperatures, longer heat time heating time the control point; The low level contact of hand switch be lower temperature, shorter heat time heating time the control point.Postpone temperature controller and be composed in series thermal circuit with the insulation indicator lamp, resistance boils indicator lamp and is composed in series to stew and boils indicating circuit with stewing, and thermal circuit is connected heat-generating disc with stewed after boiling the indicating circuit parallel connection, in heating process, postponing temperature controller disconnects in advance than temperature controller with manual reset, the temperature controller that automatically resets, stew that to boil indicator lamp bright, it is low during to its temperature controlling point that heating finishes the back cooling, and its contact engages automatically, the insulation indicator lamp is bright, stew and to boil indicator lamp and extinguish, the end of at this moment boiling enters keeping warm mode.

The utility model is reasonable in design, utilize the slow heating and the maturing process of amount slow-release, improved quality of food greatly, the multi-functional requirement of boiling has been satisfied in its multiple spot temperature control, enlarged the adaptive surface and the purposes of product, and circuit, pan structure are simple, product cost is low, reliable operation, energy-conservation is a product inexpensive, that have promotional value.
