So, the simple in construction of unit 20 is detected, it is possible to decrease the cost of electromagnetic oven 100.Such as, detecting element 22 can be placed in the receiving space formed in the middle of heating unit 10, as shown in Figure 3.
Specifically, electric capacity C and inductance L composes in parallel resonance circuit.In one example of embodiment of the present invention, detection chip 24 can adopt inductance digital converter (LDC).
When being placed with pan 50 on heating unit 10, detection chip 24 detects that the inductance L inductance value exported is the first value, and when not being placed with pan 50 on heating unit 10, detection chip 24 detects that the inductance L inductance value exported is the second value.
Processing unit 30 is by judging the difference between the first value and the second value, it is possible to judge whether to be placed with on heating unit 10 pan 50.Processing unit 30 and then can control to be placed with the work of the heating unit 10 of pan 50, and the connection of switch element 40 disconnection detection element 22 and detection chip 24 is controlled when heating unit 10 works.

Such as, in the first case, single pan 50 is different from the distance of multiple detecting elements 22 of detection unit 20, multiple detection signals that detection chip 24 exports are made to there is also difference, this species diversity when electromagnetic oven 100 designs, can be set as yes single pan 50 and cover the situation of multiple heating unit 10.Recognizable first situation of processing unit 30.
In a second situation, each detecting element 22 is roughly the same with the distance of pan 50, making multiple detection signals that detection chip 24 exports, identical (can there is nuance in multiple detection signals, but this nuance differs greatly with above-mentioned first situation, it is believed that multiple detection signal is identical in second situation), recognizable second situation of processing unit 30.
In some embodiments, display floater 70 is used for receiving user's input, and user inputs transmission to processing unit 30.Processing unit 30 for inputting the duty controlling heating unit 10 according to user.
Specifically, display floater 70 has touch-control input function.When display floater 70 shows that pan 50 is when the position of heating region 110, user can pass through display floater 70 and select such as parameters such as power gear and functions, after selection is determined, these users input is sent to processing unit 30 by display floater 70 again, processing unit 30 input, according to user, the heating unit 10 controlling to be placed with pan 50 and work.
