Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and more specifically, to an energy-saving drying oven. Background Technology

[0002] An oven is a drying device used in factories and research institutions for processes such as polymer material drying, resin curing, pharmaceutical manufacturing, paint baking, electronics, electroplating, printing baking, motor drying, transformer drying, industrial heat treatment, sterilization, heating, and heat preservation. For example, patent CN218722683U discloses an energy-saving oven, including a box body and a heater. A circulation box is fixedly connected to the top surface of the box body. The walls of the circulation box are filled with heat-insulating material. A circulation pump is installed inside the circulation box. The input end of the circulation pump is connected to the box body through an air inlet pipe, and the output end of the circulation pump is connected to the heater through a pipe. The output end of the heater is connected to the top surface of the box body through an air outlet pipe. The walls of the box body are hollow and connected to the interior of the box body. The circulation pump draws air out of the box body, heats it, and then introduces it back into the walls of the box body, and then back into the box body, thus circulating the heat carried by the air and making full use of it.

[0003] When the above-mentioned device is in use, the hot air discharged from the box is reused through the setting of the circulation box to improve the heat utilization rate. The installation box is set to collect and process the steam generated in the oven. However, after the steam is processed, the temperature will change significantly, and the circulating air needs to be reheated. At the same time, when the air flow rate is too fast, the steam cannot condense the internal water vapor, thereby reducing the drying efficiency of the items and resulting in high energy consumption of the heating equipment.
