Description
Technical field
The invention belongs to a kind of day electricity consumption cooking apparatus, particularly a kind of electric pressure cooking appliance that can change adjusting heater break-make or heating power size according to pot inner pressure.
Background technology
China ZL91100026.7 patent, provided a kind of full seal automatic multifunctional electric cooker, it adopts " Contraband " formula structure and pot cover, sealing ring, the pot body, electric hot plate, flash switch is formed the pressure automatic control mechanism of electric cooker jointly, realized that electric pressure cooking appliance pressure controls automatically, but because pressure sensing component is arranged at the utensil bottom, the pressure of institute's sensing has comprised the pot body, electric hot plate, the pressure that weight produced of pot cover and food, and the weight of food is often to change in the pot, therefore the deviation of pressure-sensing is bigger, influences the culinary art effect of pressure controling precision and food.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, providing a kind of can change the electric pressure cooking appliance of regulating heater break-make or heating power size automatically according to interior pot inner pressure.
Purpose of the present invention is realized by following technical proposals.
The present invention includes a pot body, pot cover component, interior pot, pressure control mechanism, be provided with inner pot cover in the pot cover component, be provided with sealing ring between interior pot and inner pot cover, pressure control mechanism is arranged on the pot cover component, pressure control mechanism comprises forced induction valve, displacement detector, wherein forced induction valve comprises that the cavity valve body that is arranged on the inner pot cover, the spool, the valve body lower end that are arranged in the valve cavity movingly are provided with the diaphragm seal that makes realization sealing between spool and the interior pot, the corresponding spool setting of displacement detector.
In order in the pot enough culinary art pressure to be arranged in guaranteeing, between spool and valve body, be provided with elastic mechanism;
Above-mentioned valve body can be made one with inner pot cover, also can be installed on the inner pot cover;
Above-mentioned elastic mechanism can be cylindrical spring or other elastomer;
Above-mentioned displacement detector can be the bimetal leaf pressure switch, or microswitch, or the bimetal leaf flash switch;
Above-mentioned displacement detector can direct corresponding spool be installed in the top of spool, the displacement of spool directly driven move checkout gear to produce the signal of telecommunication, thus the break-make of regulation voltage pressure cooking apparatus heater or the size of heating power automatically.
Also transmission levers can be installed between above-mentioned displacement detector and the spool, make the displacement of spool produce the signal of telecommunication by transmission levers transmission and drive displacement checkout gear, thus the break-make of automatic regulation voltage pressure cooking apparatus heater or the size of heating power.
Product based on said structure comprises safety relief valve, the anti-cap-opening mechanism of pressure state, air bleeding valve, computer or Electronic Control display system etc. toward contact, because of belonging to prior art, no longer describes in detail.
When the present invention uses, place food to be cooked in the interior pot, cover inner pot cover, inner pot cover and interior pot are realized sealing by sealing ring; When utensil does not heat, in the interior pot is atmospheric pressure state, and after the utensil energising started, heater began heating, interior kettle temperature rises, have water vapour to produce gradually, interior pot inner pressure progressively increases, when pressure during greater than valve core movement resistance and elastic construction elastic force sum, spool moves upward, directly or through transmission levers touch flash switch or microswitch or displacement transducer indirectly, produce the signal of telecommunication, thereby heater outage or heating power are reduced; The valve core movement resistance has comprised the gravity of spool, the frictional force of valve core movement etc.; Along with the outage or the heating power of heater reduces, pressure in the interior pot progressively reduces, when pressure during less than valve core movement resistance and elastic construction elastic force sum, spool moves downward, leave flash switch or microswitch or displacement transducer, produce the signal of telecommunication, thereby the energising again of heater or heating power are increased; Move in circles like this, food reaches the culinary art requirement in pot.
The present invention compared with prior art its beneficial effect is: because pressure control mechanism is arranged on the pot cover component, the pressure of institute's sensing is irrelevant with the weight of the interior food of pot, so the deviation of pressure-sensing is less, the pressure controling precision height, and the culinary art of food is effective; Simultaneously, thereby directly convert pressure signal to displacement signal and drive flash switch or the break-make of microswitch control and regulation electric pressure cooking appliance heater or the size of heating power by spool, so reliable in structure, be easy to realize, and stable performance.
