Specific embodiment
Below in conjunction with Figure of description and specific embodiment, this utility model is further described.
As shown in Figures 1 to 4, the present embodiment baking oven cooling auto-power-off device, wherein baking oven 1 include preheating section 11,
High temperature section 12 and cooling section 13, it is provided with laminar flow blower fan 14 in each section, the present embodiment baking oven cooling auto-power-off device includes
Control unit 2, temperature detection part 3 and switch module 4, temperature detection part 3 is installed in baking oven 1, and switch module 4 is series at baking
In the main power loop of case 1, temperature detection part 3 is connected with control unit 2, for the temperature that detects in baking oven 1 and believe temperature
Number send to control unit 2, control unit 2 is connected with switch module 4, for being less than default power-off temperature time control in temperature signal
The main power to close baking oven 1 for the disconnection of switch module 4 processed.Baking oven cooling auto-power-off device of the present utility model, by temperature
Degree detection piece 3 detects to the temperature in baking oven 1, and when temperature signal is less than default power-off temperature, by switch module 4
Power-off being carried out to the main power of baking oven 1, thus realizing automatically powering off, saving human resourcess；In addition structure is simple, easy and simple to handle
And be easily achieved.
In the present embodiment, switch module 4 includes main contactor 42（KM1 in Fig. 3）With auxiliary reclay 41（In Fig. 2
KA16）, auxiliary reclay 41 is connected with control unit 2, the normally opened contact string of the coil of main contactor 42 and auxiliary reclay 41
It is coupled in the same circuit, the normally opened contact of main contactor 42 is series in the main power loop of baking oven 1.As shown in Fig. 2 controlling single
Unit 2 receives temperature detection part 3（As thermocouple temperature sensor TC）Temperature signal, when temperature signal is more than default power-off temperature
When spending, control unit 2（As PLC）Output signal（Q0.7）, now the coil of auxiliary reclay 41 obtain electric adhesive, main contactor 42
Coil obtain electric, normal open switch in main power closure, circuit remains up；When temperature signal is less than default power-off temperature
When, PLC does not export, and the coil of auxiliary reclay 41 disconnects, and the coil losing electricity of main contactor 42 is normal in main power loop
