Oven with temperature-controlled opening function and control method of oven

Abstract

The invention provides an oven with a temperature-controlled opening function, which comprises a temperature controller and a temperature display device, wherein the temperature controller is composed of a temperature sensor, at least one temperature setting button, and a microprocessor MCU; the temperature sensor is in interacted connection with the microprocessor MCU, and transmits temperature information inside the oven to the microprocessor MCU for processing; the microprocessor MCU displays the processed temperature data through the temperature display device, and is further connected with an oven magnetic door coil and a beeper; an oven magnetic door coil circuit switch used for controlling the power on / off of the oven magnetic door coil is connected between the microprocessor MCU and the oven magnetic door coil; a beeper circuit switch used for controlling the work of the beeper is connected between the microprocessor MCU and the beeper. As the temperature controller is adopted to control the opening of the oven door, product function invalidation due to expansion and contraction of the product can be avoided.

Description

technical field [0001] The invention relates to a temperature-controlled oven, in particular to an oven with a temperature-controlled door opening function suitable for drying electronic components and a control method thereof. Background technique [0002] The temperature controller used in traditional ovens for baking electronic components is only used to control the baking process to maintain a constant temperature for baking. After the high-temperature baking is over, stop heating. If the oven door is opened to cool down at this time, in the case of a large temperature difference between inside and outside, it will cause the electronic components to fail due to rapid thermal expansion and contraction due to the rapid temperature drop. The phenomenon. Usually, the baked electronic component product is first cooled naturally with the oven door closed. After cooling to a certain level, the temperature difference between inside and outside is small, and the cooling speed s...

Problems solved by technology

In the above process, if the cooling process is artificially controlled, it is difficult to grasp the opening time, and the manual opening of the oven door is often difficult to control due to temperature changes, resulting in product function failure as mentioned above
