Description
Technical field
The utility model is related to electric cooker control technology, more particularly, to a kind of electric cooker with barometric pressure sensor
Control pressurer system.
Background technology
Existing luxurious electric cooker style is beautiful, and there are many function, but can not adjust pressure mostly and cause internal formation
High pressure.Current electric cooker Pressure Control Technology is controlled using differential pressure, this is resulted in when atmospheric pressure changes, pot
Interior pressure also changes therewith.And electric cooker internal temperature is limited to the temperature of water vapor, causes accessible maximum temperature in pot
Degree changes.When atmospheric pressure change increases, default requirement may be not achieved in kettle temperature, and cooking time is long, uses
Electricity is more, food quality is bad, even results in and cooks unsuccessfully.
Invention content
The technical problem to be solved by the utility model is to provide a kind of electric cooker pressure with barometric pressure sensor
Control system can ensure that absolute pressure is constant in pot, is ensured, electric meal with this according to use environment, automatic pressure regulation limit value
Kettle temperature can reach setting value during stewing meal.
Technical solution is used by the utility model solves above-mentioned technical problem：It is a kind of with barometric pressure sensor
Electric cooker control pressurer system including central processing unit, barometric pressure sensor, pressure limiting valve-driving circuit and is arranged on electric meal
Adjustable pressure limiting valve on pot, the central processing unit are connect with barometric pressure sensor, and the barometric pressure sensor is set
It puts and is used to detect atmospheric pressure on the surface of electric cooker and detection data is transferred to central processing unit, the central processing unit
It is connect with pressure limiting valve-driving circuit, the pressure limiting valve-driving circuit connect with adjustable pressure limiting valve and controls adjustable pressure limiting valve work
Make.
The further preferred embodiment of the utility model：The adjustable pressure limiting valve is mounted on the pot cover of electric cooker and itself
Voltage limiting value is adjustable.The pressure limiting valve of pressure limiting valve or the specified voltage limiting value of setting is not provided on traditional electric cooker.Specified pressure limiting valve
Voltage limiting value is smaller, when the variation of extraneous atmospheric pressure is excessive, does not have the effect for adjusting pot inner pressure value.The limit of specified pressure limiting valve
Pressure value is larger, and electric cooker is general just as pressure cooker, cooks the rice taken and is not very good eating.Therefore adjustable limit is installed on electric cooker
Pressure valve can control the absolute pressure value inside electric cooker constant, it is ensured that it is sweet and dilitious to cook the rice taken by system.
The further preferred embodiment of the utility model：The bottom that the barometric pressure sensor is mounted on electric cooker is real-time
Monitoring of environmental atmospheric pressure.Barometric pressure sensor is the important component in the utility model.Atmospheric pressure must be passed through
Sensor monitors the atmospheric pressure of electric cooker local environment in real time, thus could go to change according to the atmospheric pressure of environment adjustable
The voltage limiting value of pressure limiting valve, it is ensured that absolute pressure value is constant in electric cooker.
The further preferred embodiment of the utility model：The central processing unit includes the monolithic of model STC89C52RC
Machine and its peripheral circuit.
The further preferred embodiment of the utility model：The barometric pressure sensor uses the number of model BMP085
Pressure sensor.
The further preferred embodiment of the utility model：4th pin of the barometric pressure sensor and the of microcontroller
17 pins connect, and the 5th pin of barometric pressure sensor and the 16th pin of microcontroller connect.
The further preferred embodiment of the utility model：The pressure limiting valve-driving circuit includes operational amplifier and field-effect
Pipe, the signal of central processing unit output by field-effect tube are connected to adjustable pressure limiting valve after being amplified by operational amplifier.
Compared with prior art, the utility model has the advantage of be arranged on electric cooker so that no matter electric cooker is at what
Place uses, and can guarantee that the absolute pressure value in electric cooker is constant, and it is sweet and dilitious to cook the rice taken.The utility model is mounted on
After on electric cooker, influence of the use environment to electric cooker can be reduced, kettle temperature reaches design requirement, guarantor when ensureing to cook
Demonstrate,prove the quality of rice.
