The utility model content
The utility model provides the electric pressure cooking saucepan that a kind of pressure control is accurate, cost is low, the thermal efficiency is high at the shortcoming of above prior art.
For realizing the utility model purpose, adopt following technical scheme:
A kind of efficient heating voltage power pot, comprise pot cover, interior pot, stay-warm case, electrical heating elements and control device, described control device comprises displacement detector, be provided with sealing ring between pot cover and the interior pot, it is characterized in that in the pot with stay-warm case between be provided with the elastic component that both elasticity are connected, elastic component comprises support portion and elastic portion, and displacement detector is fixed on the below that stay-warm case is positioned at elastic portion, and electrical heating elements is fixedlyed connected with interior pot bottom.Inner pot pressure evenly is passed to displacement detector triggering pressure control device by elastic component and controls the purpose that heater circuit is realized accurate pressure control.
Described elastic component is for flat board, corrugated plating or have the resilient metal member of bending shape.The intensity height that bear the elastic component both sides of this structure, the elastic deformation of central plane part is good, the Linearity height that displacement changes in pressure.The pressure control precision improves.
The support portion of described elastic component is fixed on the stay-warm case, and interior pot places on the elastic portion.
Described electrical heating elements welds or is crimped on interior pot bottom.Can improve the thermal efficiency.
Described electrical heating elements is electrothermal tube, electric hot tray or Electric radiant Heating Film.
Described electrical heating elements is an electric hot tray, and disk center makes hollow cavity, and the elastic portion of elastic component is positioned at hollow cavity, touches interior pot bottom.
Described displacement detector changes or/and the device of switching signal break-make for detect resistance, electric capacity, inductance value by interior pot change in displacement.
The pressure control structure of electric pressure cooking saucepan compared to existing technology, the utility model beneficial effect is:
(1) because elastic component is an absolute construction with respect to stay-warm case or outer pot, the material that does not influence outer pot is selected and processing, only needs processing elastic component separately, therefore processes simple installation, and coefficient of elasticity and deformation quantity are easy to control, the deformation good linearity,
(2) electrical heating element need not to bear excessive pressure, also can ignore the thermal deformation of its generation and the pressure control that causes is inaccurate; The variation of pressure directly reacts on elastic component, comes pressure sensor by its change in displacement, the control accuracy height, and cost is low.
(3) pot adopts the mode of welding or crimping to be connected with electrical heating element in, and the thermal efficiency improves.
