Abstract
The invention discloses an electromagnetic oven with an atmospheric pressure intensity sensor. According to the electromagnetic oven, the atmospheric pressure intensity sensor is mounted at a heat radiating fan in an oven body, a heat radiating fin is mounted on the surface of the atmospheric pressure intensity sensor and is connected with a singlechip control circuit, and a liquid crystal screen is mounted on a panel of the electromagnetic oven. When the electromagnetic oven is placed in a service environment, the sensor can detect an atmospheric pressure intensity signal value of the geographical location in which the electromagnetic oven is located, transmit the signal value to the singlechip control circuit, compare the signal value with a preset atmospheric pressure value (stored in a singlechip) under which the normal work of the electromagnetic oven can be carried out, and simultaneously automatically calculate the height above the sea level of the geographical location. If the detected signal value is smaller than the preset value, a switch of the electromagnetic oven is automatically switched off, and an error code is displayed on the liquid crystal screen; and if the detected signal value is greater than or equal to the preset value, the electromagnetic oven normally works. According to the electromagnetic oven with the atmospheric pressure intensity sensor, the atmospheric pressure of a workplace of the electromagnetic oven is intelligently judged, so that the situation that the electromagnetic oven is used when the atmospheric pressure is too low is avoided, and the timely power cutoff is carried out, thereby avoiding the energy source waste. As the height above the sea level of the service environment is known, an environmental parameter is provided for scientific research.
Description
Technical field
The present invention relates to a kind of electromagnetic oven, particularly a kind of electromagnetic oven with the atmospheric pressure sensor.
Background technology
Electromagnetic oven has become one of the most frequently used Portable cookware, and it is also more and more extensive that conveniently performance makes the field of its use, is not confined to family, all brings into use electromagnetic oven in enterprise, industry spot and various operations place.Under the varying environment, atmospheric pressure affects the boiling point of water, directly affects cooking quality, and pressure is crossed the low situation that uncooked rice also may occur boiling.For the resident, local air pressure is in basicly stable state, and need to use electromagnetic oven when varying environment is cooked when all kinds of researchers test outside, just can not judge accurately whether location air pressure satisfies the condition that boils water, cooks, cause drinking unboiled water, the situation of eating living meal occurs, and affects people's health.For solving this difficulty, the atmospheric pressure sensor is installed in electromagnetic oven, is judged in use whether the atmospheric pressure of working environment satisfies the requirement of cooking of heating up water, do not require outage to quit work if reach, avoid the people to drink unboiled water and eaten living meal, also reduced unnecessary power consumption.Also can learn the height above sea level of working environment by atmospheric pressure sensor in the electromagnetic oven, provide ambient parameter to scientific research research.
Existing atmospheric pressure sensor, multiplex at aspects such as navigation, weather forecast, height above sea level measurements, present electromagnetic oven on the market is all without judging the atmospheric function in workplace.
Summary of the invention
The object of the present invention is to provide a kind of electromagnetic oven with the atmospheric pressure sensor, whether the atmospheric pressure of judging the electromagnetic oven field of employment is enough to water boiled, meal is boiled, if can not then cut off the power supply, avoid unnecessary power consumption, can learn simultaneously the height above sea level of working environment by atmospheric pressure sensor in the electromagnetic oven, provide ambient parameter to scientific research research.
To achieve these goals, technical scheme of the present invention is:
The present invention includes electromagnetic oven; To electromagnetic oven body of heater inner bottom part and away from the radiator fan place of heating disk of electromagnetic oven, the atmospheric pressure sensor surface is equipped with fin with the atmospheric pressure installation of sensors, and fin is connected with the single chip machine controlling circuit of electromagnetic oven, and liquid crystal display is housed on the electromagnetic oven panel.
Described atmospheric pressure sensor model number is: BMP085, pressure limit: 300 ~ 1100hpa supply voltage scope: the high 1.2mm of 1.8 ~ 3.6V package size: length and width 5*5mm all meets the parameters of present market electromagnetic oven.
Described fin is heat-conducting silica gel sheet, heat-stable ceramic, heat-resisting mica or not chalybeate heat-resisting or heat-barrier material.
The beneficial effect that the present invention has is:
The present invention is under the prerequisite that does not affect the existing all functions structure of electromagnetic oven, added the atmospheric pressure inducing function, can whether be enough to boil food by intelligent decision electromagnetic oven workplace atmospheric pressure, avoid the user to cross in the low and unwitting situation at atmospheric pressure and use electromagnetic oven, the situation that appearance is drunk unboiled water, eaten living meal, unnecessary energy waste has been avoided in time outage.Also can learn the height above sea level of working environment by atmospheric pressure sensor in the electromagnetic oven, provide ambient parameter to scientific research research.

Fig. 2 is the broken away view in the electromagnetic oven stove of the present invention.
Fig. 3 is the top view that the present invention removes shell.
Among the figure: 1, atmospheric pressure sensor, 2, fin, 3, body of heater, 4, liquid crystal display, 5 heating disk of electromagnetic ovens, 6, single chip machine controlling circuit, 7, radiator fan, 8, electromagnetic oven panel.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described further.
Such as Fig. 2, shown in Figure 3, the present invention includes electromagnetic oven; Atmospheric pressure sensor 1 is installed to electromagnetic oven body of heater 3 inner bottom parts and away from radiator fan 7 places of heating disk of electromagnetic oven 5, atmospheric pressure sensor 1 surface is equipped with fin 2, fin 2 is connected with the single chip machine controlling circuit 6 of electromagnetic oven, and liquid crystal display 4 is housed on the electromagnetic oven panel 8.
Described atmospheric pressure sensor model number is: BMP085, and pressure limit: 300 ~ 1100hpa(+9000m ~-the 500m height above sea level) the supply voltage scope: 1.8 ~ 3.6V package size: length and width 5*5mm, high 1.2mm all meets the parameters of present market electromagnetic oven.
Described fin 2 is heat-conducting silica gel sheet, heat-stable ceramic, heat-resisting mica or not chalybeate heat-resisting or heat-barrier material.
As shown in Figure 1, when placing the present invention in the middle of the employed environment, BMP085 atmospheric pressure sensor can detect the atmospheric pressure value of a geographic location of the present invention, this signal is sent to now existing electromagnetic oven single chip machine controlling circuit, the atmospheric pressure that the default electromagnetic oven of storing in the signal value of this moment and the single-chip microcomputer can work
Value compares, the height above sea level of simultaneously automatic calculating book invention geographic location.If the signal value that detects is less than setting value
, the switch of automatic disconnection electromagnetic oven then, and in liquid crystal screen display error code; If the signal value that detects is more than or equal to setting value
, then electromagnetic oven normal operation.
