Further, the utility model can carry out the tune of gear or duration by above-mentioned first photoelectrical coupler 4 and switch member 2
Control：
Gear or duration increase and decrease control：By the control program setting on display board, each first electric coupler 4 often detects
Primary pulse signal clockwise just adds " 1 ", often detects that primary pulse signal counterclockwise just subtracts " 1 ".
Power gear adjusting control：Can be by software set, it is " 5 " that knob, which places original speed position up, if kitchen range totally 9
A gear then increases and decreases gear institute as above.But in clockwise adjust, when its value is " 9 ", Programmable detection to next up time
When needle pulse, its value is allowed directly to skip to " 1 grade " by " 9 grades ", can so carry out clockwise gear period step-less adjustment.Inverse
When hour hands are adjusted, when its value is " 1 ", Programmable detection directly skips to " 9 to when next pulse counterclockwise, allowing its value by " 1 grade "
Shelves ", can so carry out gear period step-less adjustment counterclockwise.
Timing length is adjusted：When user has selected timing function, when program is given tacit consent to a length of " 15min ", program often detects
To a pulse signal clockwise, be increased by 1min, preferably when a length of " 99min ", program often detects a pulse counterclockwise
Signal just reduces 1min, and timing function considers dry combustion method and safety problem, be designed as can not loop cycle adjust (industry is logical
It is often such).
Further, it is additionally provided with mounting disc 6 on above-mentioned inductive switch circuit board 3, the mounting disc 6 is in the form of annular discs, center
