Description

Technical Field

[0001] The utility model relates to the technical field of drying ovens, in particular to a high-efficiency electric heating drying oven. Background Art

[0002] The electric drying oven is an indispensable and important equipment in modern industrial production. Its working principle mainly relies on heating by electric heating tubes. The electric heating tubes generate heat energy through power supply, and the blower inside the oven forms circulating wind to ensure that the heat is evenly distributed in the oven, thereby achieving a fast and uniform drying effect. However, during the operation of the electric drying oven, a large amount of water vapor will be generated in the oven due to the evaporation of water inside the object. If these water vapors are not discharged in time, they will accumulate in the oven, affecting the drying efficiency and may even cause the object to become damp or damaged. Most of the existing electric drying ovens use exhaust ducts to discharge water vapor. Although this method can solve the problem of water vapor accumulation to a certain extent, it also brings obvious disadvantages. While dissipating water vapor, the exhaust duct will inevitably take away the heat in the oven, causing the temperature inside the oven to drop, thereby affecting the drying efficiency. In addition, the loss of heat also increases energy consumption, which is contrary to the concept of energy saving and environmental protection. Utility Model Content
