TECHNICAL FIELD

[0001] The application belongs to the technical field of drying, and particularly relates to an electrical engineering automation drying device. BACKGROUND

[0002] Electrical engineering teaching involves learning, modification or expansion of a PLC control board in the process of experiment, DIY design (do it yourself) based on a disclosed substrate. The PLC control board mainly comprises a processing chip, an internal memory, a communication module, an input / output interface and a functional expansion module, etc. In the expansion process, a basic architecture is generally designed. When the function is implemented, the operator basically installs or welds components in a certain area of the control board according to the experiment or the to-be-verified demand, to realize the expansion of the function. Therefore, in the expansion process, the entire control board does not need to be cleaned and dried, and it is best to perform the related processing operation on the expansion area.

[0003] However, the existing drying treatment of the PLC control board (or the control board) adopts manual cleaning and handheld drying with a hair dryer. The drying is easy to be uneven, and the welding slag and dust generated in the welding operation process cannot be collected, which affects the tabletop environment. Some professional designed drying devices are used for drying treatment. However, the device is closed for drying the entire PLC control board, and has the defects of long processing time and low energy efficiency. The other areas of the control board are easy to be damaged, such as the processing chip and the memory area. SUMMARY

[0034] In fact, a side panel 103 is installed at the opening, which can be opened and closed. Specifically, a hinge seat 108 is installed at the bottom of the housing 100, and the bottom of the side panel 103 is inserted into the hinge seat 108 via a hinge shaft or hinge axis; a locking buckle is installed at the top of the side panel 103 for fastening.

The drive shaft 202 is inserted into the hinge hole between the two hinge rods 203 on the bottom left side and is fixed to the left hinge rod 203. It can drive the left hinge rod 203 to rotate, thereby causing the right and top hinge rods 203 to rotate. This drives the worktable 205 to move to the outside of the housing 100 and lay flat, or to move into the housing 100 and be located below the drying structure 300.

The small opening end of the first air passing shell 308 away from the air net 309 is provided with a third interface 307. When the side plate 103 closes the opening, the second interface 112 is connected with the third interface 307.

[0042] One end of the connecting branch pipe 313 is connected with the air outlet pipe 306 through the first three-way valve. The other end of the connecting branch pipe 313 is connected with a fifth interface 312. The fifth interface 312 is connected with a control valve. The control valve is connected with the second air passing shell 310 through a hose. Specifically, one end of the hose is connected with a first interface 109 connected with the control valve.
