For the ease of understanding the present invention, the present invention is described more fully below with reference to relevant drawings.In accompanying drawing
Give the better embodiment of the present invention.But the present invention can realize in many different forms, however it is not limited to herein
Described embodiment.On the contrary, the purpose for providing these embodiments is to make to understand more the disclosure
Add thorough and comprehensive.
It should be noted that when an element is considered as " connection " another element, it can be directly to separately
One element may be simultaneously present centering elements.Heretofore described " first ", " second ", " the 3rd ", " the 4th " not generation
The specific quantity of table and order, are only used for the differentiation of title.
With reference to Fig. 1 and Fig. 2, a kind of control method of PTC heating dryer, comprise the following steps：
S10：The first PTC heater elements group 200 in body 100 is electrically connected with controller 400.
S20：The 2nd PTC heater elements group 300 in body 100 is electrically connected with controller 400.
S30：Controller 400 controls the startup of the first PTC heater elements group 200 and the 2nd PTC heater elements group 300 suitable
Sequence.
The control method of PTC heating dryer of the present invention, beneficial effect caused by compared with background technology：It is logical
Cross and set the first separate PTC heater elements group 200 and the 2nd PTC heater elements group 300, controller 400 to control
The boot sequence of first PTC heater elements group 200 and the 2nd PTC heater elements group 300 so that the first PTC heater elements group 200
Full load starts when different with the 2nd PTC heater elements group 300, according to PTC resistor characteristic, can avoid producing in start-up course
Raw large impact electric current and large impact power.Therefore, above-mentioned PTC heating dryer can avoid damaging electrical equipment and improve first device
The part life-span.Wherein, controller 400 controls the boot sequence of the first PTC heater elements group 200 and the 2nd PTC heater elements group 300
Including：First PTC heater elements group 200 successively starts with the 2nd PTC heater elements group 300, the first PTC heater elements group 200
In internal heating element and the internal heating element in the 2nd PTC heater elements group 300 boot sequence.
Specifically, the first PTC heater elements group 200 and the 2nd PTC heater elements group 300 are separate.Controller 400 is logical
The power-up sequence of the first PTC heater elements group 200 of control and the 2nd PTC heater elements group 300 is crossed, realizes control the first PTC hairs
The boot sequence of the PTC heater elements group 300 of thermal element group 200 and the 2nd.
If the heating power of PTC heating dryers is 1800W, when using 1800W PTC heater elements, due to PTC
Resistance characteristic, percussion power is 1.5-2 times of rated power when 1800W PTC heater elements start, i.e. percussion power highest can
Up to 3600W, fragile component is with reducing the component life-span.
By the control method of PTC of the present invention heating dryers, the PTC heating members that two groups of power are 900W are employed
Part group, avoid using the too high PTC heater elements of power, and in start-up course, carry out the control of boot sequence, also avoid
Produce too high percussion power.
