Description
Technical field
The present invention relates to a kind of temperature control baking box, especially relate to a kind of baking box and the control method thereof with temperature control door opening function being applicable to electronic component and drying.
Background technology
The temperature controller that the baking box being conventionally used to baking electronic component adopts only is used to control in bake process, keep steady temperature to toast.After high-temperature baking terminates, stop heating, make it lower the temperature if now open oven door, can cause when internal-external temperature difference is larger because temperature reducing rate is too fast and produce electronic element products because of the phenomenon acutely causing disabler of expanding with heat and contract with cold.Usually the electronic element products Temperature fall under oven door closed condition first will be baked.Cool to a certain degree, internal-external temperature difference is less, and cooling rate slows down, and now door can be opened, and is circulated with extraneous in baking box inside, accelerates cooling further, save the time of toasting electronic element products.In above process, if manual control temperature-fall period, opening time is difficult to hold, and manually opened oven door usually causes foregoing product function failure phenomenon because variations in temperature is difficult to control.
Summary of the invention
The object of this invention is to provide a kind of baking box with temperature control door opening function solved the problem.
Object of the present invention is achieved through the following technical solutions:
A kind of baking box with temperature control door opening function, comprise temperature controller and temperature indicating device, described temperature controller sets button by temperature sensor, at least one temperature and Micro-processor MCV forms, described temperature sensor is connected alternately with Micro-processor MCV, temperature information in baking box is passed to described Micro-processor MCV process, described Micro-processor MCV is connected with described temperature indicating device, shown processing the temperature data obtained by temperature indicating device, described Micro-processor MCV is also connected with a baking box magnetic gate coil and a buzzer; Be connected with between described Micro-processor MCV and described baking box magnetic gate coil and obtain/baking box magnetic gate coil circuit the switch of power-off for controlling described baking box magnetic gate coil; The buzzer circuit switch for controlling described buzzer work is connected with between described Micro-processor MCV and buzzer.Micro-processor MCV sets button or the 3rd temperature and sets by processing the temperature data that obtains and described second temperature and compare by the temperature data of key assignments, result is relatively processed, further to Micro-processor MCV control baking box magnetic gate coil circuit switch or buzzer circuit switch send instruction.
Further, during described baking box magnetic gate coil circuit switch open, baking box magnetic gate coil losing electricity, baking box magnetic gate is in open mode.Baking box is inner to circulate with the external world, accelerates cooling further, saves the time of baking electronic element products.
Further, when buzzer circuit switch cuts out, buzzer warning.
Further, the temperature setting button of described baking box has the first temperature setting button, the second temperature setting button, the 3rd temperature setting button, three temperature setting buttons are respectively used to set different temperature, and the control method of baking box of the present invention comprises the steps
Step one, intensification and constant temperature stage, close baking box magnetic gate, open baking box inner heating device, make the temperature in baking box rise to described first temperature setting by the temperature of key assignments, constant temperature drying is carried out to the product in baking box;
Step 2, temperature-fall period, after the product in baking box is dried, stop heating up, close heater, baking box magnetic gate is still closed, and roasting the temperature inside the box is slowly declined, and causes disabler to prevent product because expanding with heat and contract with cold, when roasting the temperature inside the box is less than described second temperature of temperature setting by key assignments, baking box magnetic gate coil circuit switch open, baking box magnetic gate coil losing electricity, baking box magnetic gate is in open mode, in baking box, gas circulates with extraneous, lowers the temperature further;
Step 3, toast complete, when roasting the temperature inside the box equals described 3rd temperature of temperature setting by key assignments, buzzer circuit switch cuts out, buzzer warning, and the baking of prompting product is complete.
Beneficial effect of the present invention is mainly reflected in: the unlatching being controlled oven door by temperature controller, avoids and is caused merit product function to lose efficacy by oven dry electronic element products because expanding with heat and contract with cold.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1 is the structural representation with the baking box of temperature control door opening function of the present invention.
Detailed description of the invention
Refer to Fig. 1, a kind of baking box with temperature control door opening function of the present invention, comprise temperature controller and temperature indicating device, temperature controller sets button by temperature sensor, the first temperature, the second temperature sets button, the 3rd temperature sets button and Micro-processor MCV forms, and also comprises the baking box magnetic gate coil and buzzer that are connected with Micro-processor MCV.Be connected with between Micro-processor MCV and baking box magnetic gate coil and obtain/baking box magnetic gate coil circuit the switch of power-off for controlling described baking box magnetic gate coil, between Micro-processor MCV and buzzer, be connected with the buzzer circuit switch for controlling described buzzer work.
Temperature sensor is connected alternately with Micro-processor MCV, temperature information in baking box is passed to Micro-processor MCV process, Micro-processor MCV is connected with temperature indicating device, shown processing the temperature data obtained by temperature indicating device, Micro-processor MCV also sets button or the 3rd temperature and sets by processing the temperature data that obtains and described second temperature and compare by the temperature data of key assignments simultaneously, result is relatively processed, further to Micro-processor MCV control baking box magnetic gate coil circuit switch or buzzer circuit switch send instruction.
The job step of the present embodiment is as follows:
Heat up and the constant temperature stage, drying product is placed in baking box, close baking box magnetic gate, needed the temperature 175 degree of drying by key assignments by the first temperature setting, opening heater makes the temperature in baking box rise to described first temperature setting by the temperature of key assignments, carries out constant temperature drying to the product in baking box.
Temperature-fall period, after the product in baking box is dried, close heater, by the second temperature setting button design temperature 150 degree, expand with heat and contract with cold because temperature reducing rate is too fast to prevent product, cause disabler further, now baking box magnetic gate is still closed, roasting the temperature inside the box is slowly declined in its natural state, when roasting the temperature inside the box is less than described second temperature of temperature setting by key assignments, baking box magnetic gate coil circuit switch open, baking box magnetic gate coil losing electricity, baking box magnetic gate place opens automatically, baking box inner bulk circulates with extraneous, further cooling.
