The inductance of the resonant inductance L1 of detection judges whether the inductance value of resonant inductance L1 changes.When main control chip 13 judges resonance
When the inductance value of inductance L1 does not change, can determine that and not shelve apparatus body 20 on pedestal 10, when main control chip 13 judge it is humorous
When the inductance value of inductance L1 of shaking changes, it can determine that and apparatus body 20 is shelved on pedestal 10.
According to the Split cooking apparatus of the utility model embodiment, by setting including resonant inductance in the base
One resonant element, and pass through and sense control unit the first resonant element of control progress resonant operational to detect the inductance of resonant inductance
Amount, so that whether main control chip changes judge whether shelve apparatus body on pedestal according to the inductance value of resonant inductance,
Thereby, it is possible to easily and effectively detect whether shelve apparatus body on pedestal.
It should be appreciated that in the above-described embodiments, main control chip 13 can be according to the resonance electricity that sensing control unit 12 detects
The inductance value of sense L1 is compared with benchmark inductance value, to judge whether the inductance value of resonant inductance L1 changes.In this reality
With simultaneously Memory Reference inductance value in novel one embodiment, can be preset, so that main control chip 13 is judging resonant inductance
Whether the inductance value of L1 calls when changing.In another embodiment of the utility model, to further improve judgement
Accuracy can set in pedestal 10 and obtain benchmark inductance value with the similar structure of the first resonant element 11.
Specifically, as shown in Fig. 2, the Split cooking apparatus of the utility model embodiment may also include with reference to resonant element
14。
Wherein, it is arranged in pedestal 10 with reference to resonant element 14, is connected with reference to resonant element 14 with sensing control unit 12.
It may include that reference capacitance Cr with reference to inductance Lr with being connected in parallel with structure with reference to inductance Lr and reference capacitance Cr with reference to resonant element 14
Into LC resonance circuit, resonant operational is carried out under the control of sensing control unit 12 with reference to resonant element 14, senses control unit
12 can calculate to obtain the inductance value with reference to inductance Lr according to the resonant frequency with reference to resonant element 14.
In the embodiment of the utility model, it may include another resonance coil and another sheet metal with reference to inductance Lr, wherein,
When shelving apparatus body 20 on pedestal 10, do not deformed upon with reference to the sheet metal of inductance Lr.And the non-device capable of placing on pedestal 10
When having ontology 20, i.e. when sheet metal in resonant inductance L1 does not deform upon, in resonant inductance L1 sheet metal and resonance coil it
Between distance d1 it is equal with reference to the distance between sheet metal and resonance coil dr in inductance Lr.Also, the appearance of reference capacitance Cr
Value is arranged to equal with the capacitance of resonant capacitance C1.Therefore, no matter apparatus body 20 whether is shelved on pedestal 10, with reference to resonance
The inductance value of reference inductance Lr in unit 14 remains unchanged, and resonance electricity during with not shelving apparatus body 20 on pedestal 10
The inductance value for feeling L1 is equal.It therefore, can be using the inductance value with reference to inductance Lr as benchmark inductance value, that is to say, that main control chip
13 can be compared the electricity to judge resonant inductance L1 by the inductance value of the inductance value to resonant inductance L1 and reference inductance Lr
Whether sensibility reciprocal changes.
In a specific embodiment of the utility model, as shown in figure 3, program can be set in main control chip, and make
Program performs following steps to judge whether shelve apparatus body on pedestal：
S1 successively obtains the inductance value b of the inductance value a and resonant inductance L1 with reference to inductance Lr.
S2 judges whether there is b≤a+x.In above-described embodiment of the utility model, when resonant inductance L1 sheet metal with
The distance between resonance coil becomes hour, and the inductance value of resonant inductance L1 reduces.To further improve sensitivity, threshold doseag can be set
X when the inductance value b of resonant inductance L1 is less than or equal to reference to the sum of inductance value a and threshold doseag x of inductance Lr, enters step S3, no
Then enter step S4.In one embodiment of the utility model, x can use the value more than or equal to 0.1a.
S3 judges to shelve apparatus body on pedestal.After apparatus body having been shelved on judgement pedestal, Split cooking apparatus
Pedestal culinary art power supply or culinary art heat source can be provided for apparatus body, to carry out normal culinary art control, so as to fulfill split type
The cooking function of cooking apparatus.
S4 judges not shelve apparatus body on pedestal.After not shelving apparatus body on judgement pedestal, pedestal institute can be cut off
The culinary art power supply of offer or culinary art heat source, to ensure the safety of Split cooking apparatus.
As a result, by the first resonant element 11 that is structure is similar and being in same application environment with referring to resonant element
14 are compared, and can more accurately judge whether the inductance value of resonant inductance changes, so as to more accurately sentence
Break and on pedestal whether shelve apparatus body.
