Technical Field

[0001] The utility model relates to the technical field of drying ovens, in particular to an electrically controlled constant temperature drying oven. Background Art

[0002] Drying ovens are divided into two categories: electric blast drying ovens and vacuum drying ovens, depending on the dry material. Constant temperature drying ovens are used to test and determine the parameters and performance of electrical, electronic and other products and materials after temperature environment changes during high temperature tests due to their outstanding temperature self-control function. Therefore, they are also essential testing equipment in the fields of aviation, automobiles, home appliances, scientific research, food, and chemical products. The drying oven consists of a box body, an operating screen, a switch, an exhaust pipe, a box door, an electric heating wire, a blower and a temperature sensor, and a fixed table. When drying food, open the box door on the box body, place the food on the fixed table, then close the box door, turn on the switch, set the drying time and temperature through the operating screen, so that the blower and heating wire work to dry the food in the box, exhaust the air through the exhaust pipe, and measure the temperature in the box through the temperature sensor. When the temperature rises and drops, the power of the heating wire is controlled to maintain the temperature in the box.
