Induction cooker temperature-sensitive package failure detection method and failure detection device

The invention discloses an induction cooker temperature-sensitive package failure detection method and a failure detection device. The method comprises steps that, when a work power of an induction cooker is greater than or equal to a preset power, and the quantity of recorded values of an induction cooker temperature-sensitive package is greater than or equal to a preset number, temperature-sensitive package change amount of the induction cooker temperature-sensitive package within a first preset time segment is acquired; if the temperature-sensitive package change amount of the induction cooker temperature-sensitive package within the first preset time segment is smaller than a preset threshold, the induction cooker temperature-sensitive package is determined to be in a preliminary failure state, and the induction cooker is controlled for stopping power output; temperature-sensitive package change amount of the induction cooker temperature-sensitive package within a second preset time segment is acquired, the second preset time segment is smaller than the first preset time segment, if the temperature-sensitive package change amount within the second preset time segment is not smaller than the preset threshold, the induction cooker temperature-sensitive package is determined to be in a failure state. Through the method, a technical problem of relatively low detection accuracy rate existing in induction cooker temperature-sensitive package failure detection in the prior art can be solved.
