It has beautiful and novel appearance, adopts microcomputer temperature controller with temperature control protection and digital display, and has timing function, and the temperature control is accurate and reliable.

[0003] In actual use, when the position of the storage tray in the existing drying oven needs to be adjusted, the operator has to open the door panel and use heat-insulating gloves to manually adjust it. Each time the door panel is opened, a large amount of hot air in the drying oven will rush out, and the cold air from the outside will enter the oven, causing the temperature in the drying oven to drop rapidly. When opening the door panel to adjust the storage tray, the operator needs to wear heat-insulating gloves to operate, which increases the complexity and danger of the operation. If the gloves are damaged or the operation is improper, it may cause burns to the hands. Utility Model Content
