In this embodiment, when placing the pan on the electromagnetism stove, if pan and electromagnetism stove match, then the pan detects and can form the route between piece, the electromagnetism stove detects the piece and the control panel, therefore can produce the signal of telecommunication in this route, and then can confirm pan and electromagnetism stove whether match according to the size of the signal of telecommunication.
Specifically, acquire the pan and detect the signal of telecommunication that piece, electromagnetism stove detected the piece and the control panel formed the route, if the value of this signal of telecommunication is higher than when predetermineeing the numerical value, confirm pan and electromagnetism stove and match, if the value of this signal of telecommunication is less than or equal to when predetermineeing the numerical value, confirm that pan and electromagnetism stove are unmatched.
In this embodiment, the preset value is the minimum value when the cooker preset in the control board of the induction cooker is matched with the induction cooker, and when the value of the electrical signal is greater than the preset value, it can be considered that the cooker detection piece, the induction cooker detection piece and the control board form a normal conduction path, that is, the cooker is matched with the induction cooker.
Step 72: acquiring a pot temperature signal detected by the first temperature measuring element.
When pan and electromagnetism stove match, the pan detects a contact with the electromagnetism stove and is connected, and the pan temperature signal that first temperature element detected on the pan can detect a control panel that a transmission to the electromagnetism stove in can detecting a transmission with the electromagnetism stove through the pan, consequently, in this embodiment, when pan and electromagnetism stove match, can detect a pan temperature signal that first temperature element detected through the pan and acquire with the electromagnetism stove detects a piece to use the pan temperature signal that first temperature element measured on the pan as the standard.
Step 73: and acquiring a pot temperature signal detected by a second temperature measuring element at the bottom of the panel of the induction cooker.
When the pan is not matched with the induction cooker, the pan temperature signal that first temperature measurement component detected can't directly transmit the control panel in the induction cooker, perhaps first temperature measurement component records that pan temperature signal error is bigger, and the pan temperature signal that the control panel can't acquire that first temperature measurement component detected or the pan temperature signal that obtains this moment is inaccurate promptly. The second temperature measuring element is arranged at the bottom of the panel of the induction cooker, and the control panel can directly acquire a cooker temperature signal from the second temperature measuring element so as to control the working state of the induction cooker.
Step 74: and controlling the working state of the induction cooker according to the cookware temperature signal.
In this embodiment, according to the above step 72 and step 73, when the pot is matched with the induction cooker, the control board can acquire the pot temperature signal detected by the first temperature measurement element through the pot detection element and the induction cooker detection element, and when the pot is not matched with the induction cooker, the control board can acquire the pot temperature signal detected by the second temperature measurement element at the bottom of the induction cooker panel. The temperature of the cooker can be known at any time when the induction cooker works, and then the working state of the induction cooker is accurately controlled according to the cooker temperature signal, so that a foundation is laid for improving the heat efficiency of the induction cooker.
The cooking temperature control method provided by the embodiment of the invention comprises the steps of firstly detecting whether a cooker is matched with an induction cooker by using a cooker detection piece and an induction cooker detection piece, secondly acquiring a cooker temperature signal detected by a first temperature measurement element when the cooker is matched with the induction cooker, and acquiring a cooker temperature signal detected by a second temperature measurement element at the bottom of a panel of the induction cooker when the cooker is not matched with the induction cooker, and finally controlling the working state of the induction cooker according to the cooker temperature signal. In the technical scheme, the pot temperature signals are respectively acquired according to the matching condition of the pot and the induction cooker, and the problem of high cost caused by the use of a special communication chip is avoided on the basis of ensuring the accuracy of control.
