Abstract
The invention relates to a pressure sensor for an electric pressure cooker, which comprises a cylinder barrel with a lower opening, a piston, a pressure spring and an a potentiometer, wherein the piston and the cylinder barrel are in sliding fit with each other and subjected to liquid-gas sealing; one end of the pressure spring is matched with the piston, and the other end of the pressure spring is matched with a top plate of the cylinder barrel; and the potentiometer is driven by the piston, and a limit pressure relief hole is formed on the cylinder barrel wall between the piston and the top plate of the cylinder barrel. Due to the adoption of the structure, when the pressure in the cooker ascends, the piston moves upwards, an electrical signal of a resistor is transmitted to a control device of the electric pressure cooker; and when the set pressure requirement is met, the control device is subjected to outage to stop heating and save energy, so even if the potentiometer is damaged and the limit pressure relief hole relieves pressure, the phenomenon of cooker explosion does not occur, and potential safety hazards are eliminated.
Description
Technical field
The present invention relates to the device that a kind of electric pressure cooking saucepan is used, the pressure sensor that especially a kind of electric pressure cooking saucepan is used.
Background technology
Present prior art, a kind of pressure cooker is provided with pressure limiting valve at pot cover, and when reaching certain pressure in the pot, pressure limiting valve prevents the generation of quick-fried pot phenomenon with pressure release, the pressure signal in the pot can not be sent to control device.
Summary of the invention
The objective of the invention is: the pressure sensor that provides a kind of electric pressure cooking saucepan to use, it can to control device, prevent quick-fried pot by electrical signal transfer with the pressure in the pot, eliminates safe hidden trouble.
The present invention is achieved in that the pressure sensor that a kind of electric pressure cooking saucepan is used, and it comprises having under shed cylinder barrel, piston, compression spring and potentiometer;
Piston and cylinder barrel are slidingly matched and the liquid hermetic seal, and compression spring one end cooperates with piston, the other end cooperates with the top board of cylinder barrel; The piston actuated potentiometer, the cylinder barrel wall between piston and the cylinder barrel top board has limit relief hole.
The pressure sensor that described a kind of electric pressure cooking saucepan is used, its special character is: described potentiometer comprises two resistor disc, two resistor discs are in line and be arranged in parallel, the axis that two resistor discs are parallel to cylinder barrel is arranged in the cylinder barrel, resistor disc and cylinder barrel insulation, piston is as the connecting line of two resistor discs.
The pressure sensor that described a kind of electric pressure cooking saucepan is used, its special character is: described potentiometer comprises a resistor disc, the axis that resistor disc is parallel to cylinder barrel is arranged in the cylinder barrel, resistor disc and cylinder barrel insulation, piston and cylinder barrel are as conductor.
The pressure sensor that described a kind of electric pressure cooking saucepan is used, its special character is: top land is provided with on the top cover of spring base, cylinder barrel spring base is set, and compression spring one end is provided with on the spring base of piston, the other end is arranged on the spring base of cylinder barrel.
The pressure sensor that a kind of electric pressure cooking saucepan of the present invention is used, owing to adopt such structure, the pressure in pot rises, then piston moves up, and the resistor electrical signal transfer is to the control device of electric pressure cooking saucepan, when the pressure that reaches setting requires, the control device outage stops heating, energy savings; Even if potentiometer damages, quick-fried pot phenomenon can not appear in the pressure release of limit relief hole yet, eliminates safe hidden trouble.
