Abstract

The invention relates to a pressure displacement measure and control device of an electrothermal pressure kitchenware and a pressure measure and control method thereof. The pressure displacement measuThe invention relates to a pressure displacement measure and control device of an electrothermal pressure kitchenware and a pressure measure and control method thereof. The pressure displacement measure and control device of the electrothermal pressure kitchenware comprises a support plate, a raster mechanism, a pair of photrons, a transmission mechanism and a control circuit, wherein the surfacere and control device of the electrothermal pressure kitchenware comprises a support plate, a raster mechanism, a pair of photrons, a transmission mechanism and a control circuit, wherein the surfaceof the support plate is concavely provided with a caulking groove, the lateral edge of the caulking groove is vertically provided with a support frame; the raster mechanism is arranged in the caulkingof the support plate is concavely provided with a caulking groove, the lateral edge of the caulking groove is vertically provided with a support frame; the raster mechanism is arranged in the caulkinggroove; the photrons are symmetrically arranged at a position of the raster mechanism, which corresponds to the support plate and can induce reflection rays; one end of the transmission mechanism is groove; the photrons are symmetrically arranged at a position of the raster mechanism, which corresponds to the support plate and can induce reflection rays; one end of the transmission mechanism isconnected with the raster mechanism, and the other end is connected with a transmission component contacted with a displacement sensing part inside a pan of the electrothermal pressure kitchenware; thconnected with the raster mechanism, and the other end is connected with a transmission component contacted with a displacement sensing part inside a pan of the electrothermal pressure kitchenware; the control circuit is used for transforming the displacement of the pan inside the electrothermal pressure kitchenware into a raster signal and then processing the raster signal and sending the rastere control circuit is used for transforming the displacement of the pan inside the electrothermal pressure kitchenware into a raster signal and then processing the raster signal and sending the rastersignal to a singlechip to obtain pressure real-time information; the transmission component of the transmission mechanism amplifies the displacement amount which is generated in such a way that the pasignal to a singlechip to obtain pressure real-time information; the transmission component of the transmission mechanism amplifies the displacement amount which is generated in such a way that the pan inside the resilient sealing electrothermal pressure kitchenware is pressed, and transforms the displacement into rotating displacement to enable the raster mechanism to obtain a displacement signaln inside the resilient sealing electrothermal pressure kitchenware is pressed, and transforms the displacement into rotating displacement to enable the raster mechanism to obtain a displacement signal of the pan inside the electrothermal pressure kitchenware; the control circuit processes the displacement signal and sends the displacement signal to the singlechip, and the singlechip controls a heaof the pan inside the electrothermal pressure kitchenware; the control circuit processes the displacement signal and sends the displacement signal to the singlechip, and the singlechip controls a heating system of the electrothermal pressure kitchenware according to pressure.ting system of the electrothermal pressure kitchenware according to pressure.

Description

technical field [0001] The invention relates to a pressure displacement measurement and control device and a pressure measurement and control method for an electric heating pressure cooker. Background technique [0002] CN200510100475.9 discloses "a pressure detection method and detection device for an electric pressure cooker". Its purpose is to provide a method and device for continuously and accurately detecting and controlling the internal pressure of the electric pressure cooker by continuously measuring the deformation of the inner pot of the pressure cooker. Its technical composition: the pressure detection method of the electric pressure cooker uses a strain gauge as a detection device, places the strain gauge at an appropriate position in the space between the outer shell of the pressure cooker and the inner pot, and uses a transmission arm to sense the expansion of the inner pot When the inner pot expands due to high pressure, the transmission arm converts the exp...
