[0031] In the embodiment, the front end face of the drying box 1 is hinged with a reversible box door 18 at the left and right ends, and the outer wall of the box door 18 is fixed with a handle 180. The box door 18 is designed to be reversible, so that it is more convenient to open and close the box door, and it is convenient to put in and take out the articles to be dried.
