The utility model discloses a whether the next differentiation of level fluctuation number at measuring resonance circuit both ends is placed interior pot and is correctly placed, weak point consuming time, and when the user action product, but product short -term test pan to bring better experience for the user.
Description
Technical field
This utility model relates to culinary cuisine fixture fields, is specifically related to the inspection Pot devices of a kind of electromagnetic heating electric rice cooker.
Background technology
Electromagnetic heating electric rice cooker in the market is when choosing function and entering culinary art, first each functional module of product is detected, just began to warm up after needing the several seconds, if user forgets interior pot is put in electric cooker and cannot be pinpointed the problems in time, lose time, life is brought inconvenience, affects Consumer's Experience.
Summary of the invention
This utility model proposes for solving prior art Problems existing, its objective is to provide the inspection Pot devices of a kind of electromagnetic heating electric rice cooker.
The technical solution of the utility model is: the inspection Pot devices of a kind of electromagnetic heating electric rice cooker, including EMC suppression circuit, current rectifying and wave filtering circuit, resonance circuit, on-off circuit, drive circuit, first testing circuit, second testing circuit, control chip and external signal testing circuit, and it is sequentially connected with current rectifying and wave filtering circuit after power supply input EMC suppression circuit, resonance circuit, control chip connects external signal testing circuit respectively, drive circuit, first testing circuit, second testing circuit, drive circuit is sequentially connected with on-off circuit and resonance circuit, first testing circuit and the second testing circuit connect the two ends of resonance circuit respectively.
By detecting the level change frequency at resonance circuit two ends, this utility model distinguishes whether pot in placement is correctly placed, consuming time short, when user operation product, product can quickly detect pan, thus bringing better experience to user.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein:
1EMC suppression circuit 2 current rectifying and wave filtering circuit
3 resonance circuit 4 on-off circuits
5 drive circuit 6 first testing circuits
7 second testing circuit 8 control chips
9 external signal testing circuits.
Detailed description of the invention
Hereinafter, with reference to drawings and Examples, this utility model is described in detail:
As shown in Figure 1, a kind of inspection Pot devices of electromagnetic heating electric rice cooker, including EMC suppression circuit 1, current rectifying and wave filtering circuit 2, resonance circuit 3, on-off circuit 4, drive circuit 5, first testing circuit 6, second testing circuit 7, control chip 8 and external signal testing circuit 9, it is characterized in that: after power supply input EMC suppression circuit 1, be sequentially connected with current rectifying and wave filtering circuit 2, resonance circuit 3, control chip 8 connects external signal testing circuit 9 respectively, drive circuit 5, first testing circuit 6, second testing circuit 7, drive circuit 5 is sequentially connected with on-off circuit 4 and resonance circuit 3, first testing circuit 6 and the second testing circuit 7 connect the two ends of resonance circuit 3 respectively.
Described control chip 8 adopts 8 single-chip microcomputers or ARM kernel series.
Described on-off circuit 4 is IGBT.
When control chip 8 detects the entrance mode of operation that external signal 9 provides, control chip 8 exports 2-10uS and is pulsed into drive circuit 5, and the pulse that control chip 8 exports is converted into VCC Automatic level control IGBT and is turned on and off by drive circuit 5.IGBT closes resonance circuit 3 of having no progeny and produces LC vibration, whether whether resonant tank 3 both end voltage is detected by control chip 8 by the first testing circuit 6 and the second testing circuit 7, distinguish have pan or pan correct in electric cooker by comparing the magnitude of voltage of the first testing circuit 6 and the second testing circuit 7.When coil panel has pot in correctly, the energy of resonance circuit 3 is quickly absorbed by pan, and the level change frequency that now control chip 8 detects is less；When on coil panel without interior pot or interior pot incorrect time, the energy of resonant tank 3 can not quickly be absorbed by pan, and the level change frequency that now control chip 8 detects is more, by level change frequency distinguish placement in pot whether correctly place.This kind of detection method is consuming time short, and when user operation product, product can quickly detect pan, thus bringing better experience to user.
