Description

Technical Field

[0001] The utility model relates to the technical field of drying machines, in particular to a lunch box drying machine which is easy to adjust. Background Art

[0002] The lunch box dryer uses a specific drying method to quickly evaporate the moisture inside and outside the lunch box, thereby drying and cleaning the lunch box. This equipment is usually suitable for places such as the catering industry, schools, and factories where a large number of lunch boxes are used. The working principle of the lunch box dryer is mainly based on three methods: heat conduction, heat convection, and heat radiation. When the lunch box is placed in the dryer, hot air or other heat sources will be conducted to the surface of the lunch box, causing the surface temperature to rise. As time goes by, the moisture inside the lunch box gradually evaporates under the influence of heat conduction, convection, and radiation, thereby achieving the drying effect.

[0003] Most of the placement plates of existing lunch box dryers are fixedly connected to the inside of the dryer, and the position of the placement plates cannot be adjusted, which results in a fixed distance between adjacent placement plates. When users need to dry lunch boxes of different sizes, on the one hand, some lunch boxes with higher heights are easily blocked and are not easy to place on the placement plates. On the other hand, the space utilization of the dryer is unreasonable, which is not conducive to placing more lunch boxes for drying, causing unnecessary trouble to users, inconvenience to users, and reducing the practicality of the dryer.
