Description
Technical field
The utility model relates to a kind of temperature controller, specifically is a kind of heter temperature controller that is used for.Be specially adapted to food heater tool such as buffet furnace and do electron temperature control; Automatically the control firing equipment heats buffet furnace.
Background technology
Traditional buffet furnace does not generally have heating function.The mostly employing alcohol heater heating of band heating function is arranged, or solid alcohol heats.Heating-up temperature can't be accurately controlled in these heating measures, and the temperature of food also can't measure and show, therefore can't control; Thereby the temperature of food can't be controlled at optimum condition.In recent years; some also having occurred uses electric heating plate to heat; but this electric heating plate has just adopted a thermal protector to protect basically, and the heat protection that so only reaches setting the time can disconnect electric heater, thereby can't carry out accurate temperature controlling.Also can't measure and control middle temperature.
Summary of the invention
Unresolved the problems referred to above, the utility model provide a kind of heter temperature controller.Can show the temperature that keeps in the current meal stove in real time, this temperature controller is positioned temperature for five set points simultaneously.By one button being set simply changes.The temperature that sets is clearly indicated by the pilot lamp of representing each set point.Temperature control is accurate, simple to operate, practical, and is with low cost, energy savings.
The utility model is realized by following scheme: a kind of heter temperature controller comprises:
-microcontroller,
-reset circuit is connected with micro-control circuit, is used for microcontroller and resets;
-temperature sampling circuit is connected with micro-control circuit, is used to gather current heating-up temperature;
-power supply stabilization circuit is connected with micro-control circuit, provides stabilized voltage supply to temperature controller;
-display output circuit is connected with micro-control circuit, is used for display setting temperature and Current Temperatures;
-button inputting circuits is connected with micro-control circuit, is used to import each parameter of adjusting setting;
-output control circuit is connected with micro-control circuit, is used for control output.
Temperature sampling circuit is gathered the well heater Current Temperatures and is imported microcontroller, shows Current Temperatures by display output circuit, and according to the temperature value heating of setting.When needs change design temperature, change by the temperature setting key in the button inputting circuits.Make the state of temperature that food remains on to be needed.
The beneficial effects of the utility model are: at the design of self-service heating meal stove, temperature control is accurate, simple to operate, practical, and is with low cost.Energy savings.

Embodiment
As shown in Figure 1, the heter temperature controller is made up of microcontroller, temperature reset circuit, temperature sampling circuit, power conversion and mu balanced circuit, display output circuit, button inputting circuits and output control circuit.
As Fig. 2, shown in Figure 3, PART6 is microcontroller MCU, employing be the HT46F49E single-chip microcomputer of HOLTEK company; PART1 is the MCU reset circuit; PART2 is a sample circuit; PART3 is a controlling output circuit; PART4 is a power supply stabilization circuit; PART5 is the MCU oscillatory circuit, and PART7 is a button inputting circuits, and PART8 is a display circuit.Sample circuit adopts temperature sensor, and what present embodiment adopted is that thermistor is made temperature sensor.
Major part of the present utility model is that PART7 and PART8 realize, remainder is other application circuit of present embodiment, will not describe in detail, describes button inputting circuits PART7 of the present utility model and display circuit PART8 below in detail.Display circuit PART8 adopts charactron and light emitting diode.
In button inputting circuits PART7, be provided with temperature setting key S1 and power key S2, when temperature setting key S1 and power key S2 all do not have when pressing, microcontroller PART6 is in normal operating conditions, at this moment, what the charactron in the display circuit PART8 showed is when the measured temperature of front sensor, the lumination of light emitting diode of current design temperature correspondence in LED1～LED5.When temperature is lower than design temperature, the heating relay closes, heater block begins heating.When temperature rises to design temperature and adds the temperature difference of a regulation, add electrothermal relay and disconnect, heater block stops heating.When heater block heated, pilot lamp LED 7 was luminous.
When temperature setting key S1 is pressed, what charactron showed is the Current Temperatures setting value, light emitting diode among the corresponding D1～D5 of design temperature also rises bright, when in official hour T1, pressing once more, whenever adjust according to the temperature spot of setting by a design temperature, charactron also and then shows adjusted setting value, and the light emitting diode of design temperature correspondence also and then refreshes among D1～D5.During no actuation of keys, charactron returns the temperature that shows that probe records in official hour T1, and controller is according to new design temperature control operation.
In working order down, press the S2 key and surpass official hour T2, controller cuts out, and except that pilot lamp LED 6 was luminous, all the other did not show that all pilot relay disconnects.
Under the controller closed condition, press the S2 key, controller is opened and is moved according to the expectant control mode.
In working order down, press S1 and the S2 T3 that exceeds schedule time simultaneously, then button is pinned, at this moment, all can not carry out temperature setting and controller start-stop operation controller by function key and power key.
The foregoing description shows by temperature sampling circuit measurement target temperature and in the charactron zone, and makes corresponding to corresponding lumination of light emitting diode indication according to the value of design temperature.When carrying out the design temperature change, when pressing the adjustment key, charactron shows current set temperature value.Whenever by once adjusting key, design temperature is adjusted one in five design temperature point cocycles of presetting.The also corresponding change of corresponding light emitting diode.After pinning power key and exceeding schedule time, can the closing temperature controller, under the closed condition, after pinning power key and exceeding schedule time, can open temperature controller.Under the normal boot-strap state, press power key simultaneously and can pin and open keypress function above official hour with the adjustment key, under the state that keypress function pins, can not change set temperature value.
