Abstract

The invention discloses a dryer control device, relating to the technical field of manufacturing of electric equipment. The dryer control device comprises a control box; a first contactor and a second contactor are installed in the control box; a shift switch, buttons and a PLC (Programmable Logic Controller) are installed on a door of the control box; the shift switch and the buttons are respectively connected with corresponding ports of the PLC; one end of a first contactor coil is connected with a port of the PLC, one end of a second contactor coil is connected with a port of the PLC, the other end of the first contactor coil is connected with the other end of the second contactor coil and then connected with another port of the PLC. The dryer control device can solve the problems of complex circuits and poor control precision.

Description

technical field [0001] The invention relates to the technical field of electrical equipment manufacturing; in particular, it is a control device used to control a dryer. Background technique [0002] The dryer is a special equipment for drying items. When drying items, in order to ensure the drying quality of the items and reduce the loss of dryer parts, in addition to requiring automatic temperature control, intermittent ventilation is also required. The existing dryer control Circuits are mostly controlled by contactors and relays. The problem with this control method is that the circuit is complex and the control accuracy is poor. Contents of the invention [0003] The object of the present invention is to provide a dryer control device, which can solve the problems of complicated circuit and poor control precision. [0004] In order to solve the above problems, the technical solution adopted by the present invention is: the dryer control device includes a control box,...
