Description

The intelligent temperature control pressure electric cooker that declines

Technical field

The utility model relates to a kind of household electrical appliance, particularly a kind of intelligent temperature control that is used for boiling automatically pressure electric cooker that declines.

Background technology

Electric cooker is a kind of household electrical appliance of having popularized, and common electric cooker does not have pressure when cooking, and it is second-rate to boil, and function ratio is less; Though electric pressure rice cooker has improved cooking quality, its control circuit complex structure, pressure is bigger when boiling, and has brought unsafe factor, and cost cost height; The computer-shape electric pressure rice cooker utilizes computer chip and fuzzy technology control, has optimized the combination property of electric cooker, has both improved reliability, the stability of work, improved the quality that boils again, but significantly increase product cost simultaneously, the selling price costliness is difficult to popularization and application.Also have some patents, proposed improvement project from aspects such as energy-conservation, function, structures, but failed synthetically to resolve the problems referred to above all the time about the electric cooker aspect.My patent application 02227330.1 utilizes amount slow-release to finish automatically and boils, boil and finish at the minute-pressure state, it is simple to operate easy to use, reached intelligent control effect, energy-saving effect is remarkable, but it only relies on the temperature controller of control circuit to control automatically, just in case temperature controller control is malfunctioning, the meeting build-up of pressure is too high, has certain potential safety hazard.

Summary of the invention

The purpose of this utility model is that a kind of improved intelligent temperature control pressure electric cooker that declines is provided for the shortcoming that overcomes above-mentioned prior art, optimizes product structure, and realizes intelligent control, improves boil quality and security performance.

The purpose of this utility model can realize by following technical measures: this minute-pressure electric cooker has pot shell, pot inner casing, pot courage, pot lid, easing valve, pressure hammer, heat-generating disc, control circuit, pot courage is packed in pot inner casing, pot covers spiral-lock at pot inner casing, the sealing of pot courage, the easing valve that pot covers, pressure hammer plays safety, the pressure limiting effect, heat-generating disc is contained in pot inner casing and directly contacts with pot courage, the temperature controller with manual reset of control circuit is installed on the interior shell side wall of pot, contact with pot courage, the reset key of temperature controller with manual reset directly is attached to pot case surface, can directly reset from outer button, pressure sensitive switch, thermostat, little heating board is installed in pot inner casing bottom surface, temperature controller with manual reset, pressure sensitive switch, heat-generating disc is composed in series heating control circuit, thermostat and little heating board are composed in series constant-temperature circuit, heating control circuit is in parallel with constant-temperature circuit, heat-generating disc is a slowly-releasing heat heat-generating disc, indicator lamp and resistance are composed in series indicating circuit, insulation indicating circuit temperature controller with manual reset in parallel, pressure indicating circuit one end connects between the indicator lamp and resistance of insulation indicating circuit, and the other end connects the pressure sensitive switch power connection.During application, buckle well pot lid, button makes temperature controller with manual reset connect the heat-generating disc power supply, and heat-generating disc is to the heating of pot courage, and pot courage temperature rises, when temperature arrives the temperature controller with manual reset temperature control point, the temperature controller with manual reset auto power off, the insulation indicator lamp is bright, continues the release heat heating by slowly-releasing heat heat-generating disc and boils, when in pot courage pressure being arranged, pot courage is to pressing down pot inner casing, and pressure sensitive switch disconnects, and the insulation indicator lamp extinguishes, pressure indicator light is bright, reduce to no pressure when pot courage internal pressure, pressure sensitive switch is connected, and pressure indicator light extinguishes, the insulation indicator lamp is bright, and can uncap edible this moment.

The utility model utilizes amount slow-release to finish automatically and boils, heat slowly, pressurization and maturing process, improved quality of food greatly, it is reasonable in design, control circuit, pot body structure simple, the pressure that boils is low, security is good, and the product integrated cost is lower, uses processing ease, having reached intelligent control effect, is a kind of intelligent household appliances of Nover practical.
