The surface of the internal frame 3 is provided with stacked drying trays 2. The inner wall of the drying chamber 1 is fixedly connected with the hot air drying assembly 4. The hot air drying assembly 4 includes a heating chamber 6, a fan 7, and an exhaust duct 8. A plurality of electric heating wires 9 are fixedly connected inside the heating chamber 6. The fan 7 is fixedly installed at one end of the heating chamber 6. The other end of the heating chamber 6 is connected to the exhaust duct 8. The exhaust duct 8 is fixedly installed on the inner wall of the drying chamber 1.

[0021] In a further improvement, the built-in frame 3 includes a fixing rod 10, a tray 11, and a locking handle 12. The fixing rod 10 is vertically fixedly connected to the inside of the drying chamber 1. The tray 11 is located on the surface of the fixing rod 10 and is slidably connected to the fixing rod 10. The side wall of the tray 11 is provided with a threaded locking handle 12. By providing an adjustable tray 11 on the surface of the fixing rod 10, it is convenient to adjust the longitudinal height and to stack the drying trays 2.

[0022] In a further improvement, the side wall of the support plate 11 is provided with a locking hole 13, and the locking handle 12 is embedded in the locking hole 13 and threadedly connected to the locking hole 13. By providing a locking hole 13 on the side wall of the support plate 11 that is threadedly connected to the locking handle 12, it is convenient to adjust the position of the support plate 11 on the surface of the fixing rod 10, and at the same time improve the stability of the connection between the support plate 11 and the fixing rod 10.
