The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As shown in the figure, the electric pressure cooker pressure-detecting device of this directly accurate detected pressures, pot 5 in mainly comprising, outer pot 7, chassis 6, heat-generating disc 8 and pot cover 10, interior pot 5 is located in the outer pot 7, the bottom of outer pot 7 is provided with chassis 6, the top of outer pot 7 and interior pot 5 is provided with pot cover 10, the bottom of outer pot 7 is provided with heat-generating disc 8, heat-generating disc 8 contacts with the bottom outer surface of interior pot 5, pot cover 10 is provided with filter 4, filter 4 is provided with fixture 3, pot cover 10 is provided with pressure sensor 1, and pressure sensor 1 links to each other with fixture 3, is communicated with by conduction pipe 2 between pressure sensor 1 and the fixture 3, because the temperature in the pot is higher, to reduce the influence of temperature to pressure sensor 1, if pressure sensor 1 has enough heatproofs, pressure sensor 1 is also directly on the fixing device for installing 3 or in the embedding fixture 3 by conduction pipe 2, pot cover 10 is provided with a plurality of pressure sensors 1, and each pressure-detecting device all is electrically connected with central controller 9.Electricity pressure cooker inside is provided with central controller 9, and central controller 9 is located at outer pot 7 sidewalls, or on the pot cover 10, or electric pressure cooker bottom.Interior pot 5 peripheries or pot cover 10 inner surfaces are provided with temperature sensor, temperature sensor is electrically connected with central controller 9, be used to detect kettle temperature, pot cover 10 is provided with steam electromagnetic valve, dynamically control steam in the pot, thereby, make central controller 9 implement control and detection from several aspects such as pressure, temperature to the culinary art situation of pressure cooker.Between pressure sensor 1 and the central controller 9, by being electrically connected, central controller 9 is connected with the remote controllers signal as signals such as computer controlling center, remote controller, household intelligent control modules and is electrically connected between central controller 9 and the display device.
The utility model mainly adopts the pressure sensor 1 that can directly detect pot inner pressure as detection means, more accurately and fast, reliably, and can detection effect in the absolute pressure of foodstuff surface, also can detect relative pressure.Pressure sensor 1 inside is packaged with a standard pressure value, by the detected pressure of pressure inside detection chip, compare conversion with the standard pressure value, thereby the absolute pressure of obtaining, the pressure detecting chip is to utilize the Wheatstone bridge principle, change pressure into the chip manageable signal of telecommunication, this signal of telecommunication installs inner packaged integrated circuits through this to carry out forming the stable detection signal of telecommunication after signal is handled.This Device Testing method is: when electric pressure cooker does not heat, pressure sensor 1 detects external atmospheric pressure, and pass to central controller 9, so that regulate the pot inner pressure control point, when pot inner pressure raises, produce steam, form relative pressure, pressure sensor 1 detects the superposition value---absolute pressure of the relative pressure that produces in atmospheric pressure and the pot, when pot inner pressure reduces, detect the interior absolute pressure size variation of pot by pressure sensor 1 equally, pressure directly acts on the pressure sensor 1 pressure detecting chip by conduction pipe 2 and converts the signal of telecommunication to, after inner packaged integrated circuits processing, pass to central controller 9 and carry out computing, output control signal and demonstration signal.
Because pressure sensor 1 can continuous detecting and is exported the corresponding signal of telecommunication, thereby make central controller 9 implement monitoring pot inner pressure and ambient pressure continuously, cut off the electricity supply as implementing, adjust pressure control point, open steam electromagnetic valve etc., central controller 9 also can help intuitively to show pot inner pressure.If central controller 9 is connected with the remote controllers signal, can also realize remote monitoring function, thereby intelligent residence is managed, design is provided convenience.Simultaneously, because this device can detect absolute pressure, when external atmosphere pressure changed, central controller 9 can the automatic pressure regulation control point, makes the absolute pressure that acts on foodstuff surface keep balance, reaches the best effect of cooking.
In addition to the implementation, all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
