Wireless power transmission receiving circuit, communication method, and wireless power transmission system

A heating control device for controlling a food processor is disclosed. During a heating process of the food processor, a temperature in a cup of the food processor is obtained at a predefined time interval. Whenever the obtained temperature in the cup reaches a current preset temperature threshold, the food processor starts a stirring operation for a first preset time period and stops after that, until the obtained temperature in the cup is greater than an upper limit of the preset temperature threshold. The preset temperature threshold is adjusted and defined as the current preset temperature threshold every time before the food processor starts the stirring operation. The heating control device for controlling the food processor solves a problem of a low accuracy in heating control that is caused by an unbalanced temperature in the cup of the food processor during the heating process.
