Change the value that result is very little, i.e. v1(or v2 or v3) less than minimum setting value.
If t1+, t1-(or t2+, t2-, or t3+, t3-) between do not have kitchen range access, then ad1(or ad2, or
Person ad3) transformation result is very big value, i.e. v1(or v2 or v3) it is more than maximum set value.
If t1+, t1-(or t2+, t2-, or t3+, t3-) between access and have the power component of kitchen range, then ad1(or
Person ad2, or ad3) transformation result is certain value middle, that is, minimum setting value < v1(v2 or v3) < maximum set value.
In the present embodiment, minimum setting value is more than 0, and maximum set value is less than the simulation numeral input pin of single-chip microcomputer
Maximum input level max.That is, 0 ＜ minimum setting value ＜ maximum set value ＜ max.In the present embodiment, minimum setting value is chosen as
Max*5%, maximum set value is chosen as max*80%.
For the ease of reminding whether user's kitchen range are placed properly, multipair led is additionally provided with platform, multipair led and many
Power supply contact is corresponded.Each pair led includes a ruddiness led, a green glow led, and main control unit controls the bright of each pair led
Go out.Between a pair of power supply contact during the power component of access kitchen range, main control unit controls corresponding green glow led bright, otherwise controls
Make corresponding red led bright.
The kitchen range structure of the present embodiment, it is achieved that platform separates with kitchen range, can place multiple kitchen range on a platform,
One control panel can control electricity on the power component of multiple kitchen range to run, it is to avoid this internal design electric control part in each kitchen range
Point, decrease the wasting of resources；And the design of kitchen range and platform is simpler, reduce further cost；And using more square
Just, there is the stronger market competitiveness.
Certainly, described above is not to restriction of the present utility model, and the utility model is also not limited to the example above,
Change, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model,
Also protection domain of the present utility model should be belonged to.
