Connection, i.e.,：Air blast motor will must be opened also when heating module is opened, and air blast motor is opened then heating module and can be opened also not
It opens, two opening sequences loaded and switch have necessary logical relation, and circuit damage otherwise can be caused even to endanger
Danger.
Traditional wind as shown in Figure 1 warms up type heater, and it is individually only to load 1 (air blast motor) and 2 (heating modules) of load
Vertical work, if if not having any contact independent operating between two loads, it is not have that tradition wind shown in FIG. 1, which warms up type heater,
Problem.But 1 (air blast motor) of load and 2 (heating modules) of load are relating operations, corrrect usage is elder generation when work
1 (air blast motor) of load is opened, load 2 (heating module) is then turned on, just can guarantee the temperature control in warmer box in this way
In certain range, to ensure the safety and reliability of heater.Otherwise the heat band that heating module generates does not go out outside machine
Savings can be such that built-in temperature steeply rises in machine, serious or even draw to influence the reliability and stability of entire product
The accident of rising.Product on the market is mostly to use control mode as shown in Figure 1, and this problem and defect are：1, installation personnel
Wrong line can not be found, cause to increase after sale；2, user only opens heating module and is not turned on air blast motor, leads to not normal
Use and damage machine.
