Description
Technical field:
The invention belongs to hot electric pressing pressure cooking apparatus for kitchen use, is electromagnetic heating technique application product patent.
Background technology:
In China, the electric pressure cooking saucepan product based on the architectural feature of Chinese ZL91100026.7 patent of invention has begun to enter common people family. the mode of heating that the patented product adopted, continued to use the aluminium electric hot tray that electric cooker is used.Because the thermal inertia of aluminium electric hot tray is bigger, the pressure overshoot after causing cutting off the power supply makes the accuracy of pot inner pressure control be subjected to very big influence.And the electromagnetism mode of heating has characteristics such as thermal efficiency height, thermal inertia are little, therefore substitutes aluminium electric hot tray mode of heating of the prior art with the electromagnetism mode of heating, can improve the performance and the energy savings of product greatly.
Summary of the invention:
At the deficiencies in the prior art, the present invention proposes to substitute electric hot tray of the prior art with electromagnetic heater, one can solve the big pressure overshoot that causes of thermal inertia owing to electric hot tray, influence the problem of pot inner pressure control accuracy, two because mode of heating and heat the different of principle, the heat conduction efficiency of electromagnetic heater is higher tens percentage points than electric hot tray, therefore the consumption that can save the energy greatly.
The present invention is made up of pot cover, interior pot, outer pot, sealing ring, elastic arm, switch etc.Wherein, pot cover and outer pot are rigidly connected, and are connected by sealing ring between pot cover and the interior pot, and elastic arm is arranged between the outer pot bottom and the interior the bottom of a pan, switch is arranged on the displacement drive that outer pot bottom is accepted elastic arm, and electromagnetic heater is arranged on the interior the bottom of a pan and connects into power supply with switch series.Operation principle of the present invention is: behind the switch connection power supply, and water and food in electromagnetic heater begins to heat in the pot.Pressure begins to rise after entering sealing state in the pot. and pot inner pressure acts on pot cover and the interior pot simultaneously, because pot cover and being connected to of outer pot be rigidly connected, so pot cover can not be to top offset.Pressure in acting on the pot is delivered on the elastic arm from interior pot bottom, elastic arm just produces downward displacement (deformation) based on its elastic characteristic, this displacement drive switch cuts off the power supply of electromagnetic heater. afterwards, pot inner pressure descends because of natural heat dissipation, along with the elastic arm that reduces of pressure upwards restores gradually, the driving force that acts on the switch is also reduced thereupon, power to be driven be reduced to switch reset again the energising after, interior pot is reheated, pot inner pressure also transfers rising to from decline ... in this process that moves in circles, and the force value in the pot is controlled on switch and the determined force value of pressure displacement parameter all the time.Electromagnetic heater among the present invention is made up of panel, coil, electromagnetism circuit etc., and it is the device that converts electric energy to magnetic energy.Pot cover and outer pot are rigidly connected under the safe pressure effect in scope of design of being meant, being connected between pot cover and the outer pot is regarded as that strain or elastic deformation amount can not be taken place and can ignores, the connected mode of the two can be the revolving type as the revolving type pressure cooker, also can be the buckle closure formula as the Contiuum type electric cooker.Elastic arm refers to possess the structure of elastic characteristic, and its function is that its version can have multiple with the break-make of the strain gauge tap that produces under the pot inner pressure effect, as: the spring assembly that one or several disk springs are combined into; The spring assembly of forming with a plurality of cylindroid helical-coil compression springs or with steel plate make with elastomer of various reinforcement structures or the like.
The present invention proposes, elastic arm can also be made one with the outer the bottom of a pan, be bellows-shaped or disk spring is tabular, if the bucket wall of outer pot is proper with the transition arc design in the outer the bottom of a pan, also can obtain required elastic displacement, can therefore save all the other ripples on the outer the bottom of a pan. between the elastic arm (the outer the bottom of a pan) and the interior the bottom of a pan power transmission part is set, its function is that the pressure that will act on the interior the bottom of a pan passes to elastic arm.
The present invention proposes, and an electronic controller can be set on circuit, and it comprises timer, master switch etc., when first time that electronic controller receives switch after the break signal, just starts timer and begins to control cooking time.During the concluding time, timer cuts off master switch to predetermined culinary art, thoroughly stops the heating power supply of electromagnetic heater.
The present invention proposes, and shell and pot cover part can be taked the insulation measure, and purpose is the temperature retention time energy savings that increases after cutting off the power supply.
Employed cast aluminium electric hot tray in the prior art has following shortcoming: the one, its internally pot what add thermal recovery is the contact heat exchange pattern.This mode of heating is earlier with behind the electric hot tray heat temperature raising, by the temperature difference that forms between the electric hot tray and the interior the bottom of a pan inwardly pot carry heat energy. heat-conductive characteristic between the two is proportional with the high power of temperature gap between the two, usually electric hot tray need be heated to more than 200 ℃, the temperature of pot reaches or maintains (about 100 ℃～120 ℃) on the required cooking temp in just making, remaining energy then consumes in the process of heating electric hot tray and heat transmission, not only cause waste of electric energy, form a hot environment near also making electric hot tray, make the heatproof of product correlated parts require to improve, the thing followed is that cost strengthens, disadvantages such as damage probability increase.The 2nd, after pot inner pressure reached the control point, and the displacement drive switch of elastic arm cuts off the power supply, the remaining high temperature of electric hot tray continued to pass to interior pot, and the pressure of pot described pressure overshoot phenomenon occurs at pressure control point still continuation rising later in making.This phenomenon can make pot inner pressure control temporarily be in runaway condition, directly influences the accuracy of pot inner pressure control, also has certain harmfulness on product safety, therefore can not ignore and disregards.Three are based on the contact heat conduction of electric hot tray and the double action of the interior the bottom of a pan of carrying pressure, prior art has quite strict requirement to the contact condition in the electric hot tray and the interior the bottom of a pan, though product can both reach requirement when dispatching from the factory, but the unavoidable distortion that occurs in various degree of pot bottom in daily use, after distortion reaches to a certain degree, will make the loose contact of the two, cause properties of product to descend even can not use fully.And the electromagnetic heater that the present invention adopts according to pot in the heating of electromagnetism heating principle, because of himself not needing heat temperature raising, so there is not waste heat to exist after the outage, just the pressure overshoot phenomenon can not occur yet, can improve pressure controlled accuracy effectively.In addition, because the interior the bottom of a pan that the magnetic line of force that electromagnetic heater produces directly heats magnetic conduction, so the thermal efficiency exceeds tens percentage points than the mode of heating of electric hot tray, except that saving energy, the thermal environment bottom the product also improves.Have again, because the electromagnetism mode of heating belongs to contactless heat transfer, the pressure in the bottom of a pan in electromagnetic heater need not carry again, so it and the requirement that does not have strictness cooperating of the interior the bottom of a pan, not only simplified production technology, product had in use both made the distortion of the generation the bottom of a pan also can not influence result of use.
Though used for reference the Contraband formula structure of Chinese invention patent ZL91100026.7 in the present invention, but the present invention is not the simple combination of electromagnetic oven and Contraband formula structure, need in force to make the two form an overall structure, to adapt to new mode of heating by Electromechanical Design.Antimagnetic design of the mechanics design of the form fit design of stressed design, coil and the interior pot in the magnetic conduction design in the pot the bottom of a pan in Electromechanical Design comprises, the interior pot the bottom of a pan, the shaped design of panel, power transmission part and the design of non-magnetic conduction, elastic arm or the like.On structural design, because electromagnetism is heated to be untouchable heating, so contacting between the pot in panel and the magnetic conduction only needs press electromagnetic oven and get final product with the standard design that contacts in the bottom of a pan, design the requirement that strictness is arranged and need not as prior art the contact heat of electric hot tray conducted.Also can be according to the shape and the area of the bottom of a pan heating surface in the Demand Design magnetic conduction of culinary art, power distribution situation with pot bottom in controlling, this not only can improve the cooking quality of rice, when big capacity cooking rice, also can significantly reduce the sallow phenomenon of pot bottom rice, to sum up state visible enforcement of the present invention and have vast market prospect.
