Heating control device, heating control method and cooking appliance

Abstract

The invention provides a heating control device, a heating control method and a cooking appliance. The heating control device comprises a DC power supply circuit, an AC power supply circuit, an AC/DC selection circuit and a detection control circuit, wherein the AC power supply circuit is connected with the AC/DC selection circuit; one end of the AC/DC selection circuit is connected with the detection control circuit, and the other end is connected with an object to be heated; and the detection control circuit is used for detecting a resistance value and/or a current value of the object to be heated, determining whether the object to be heated is a detachable heating plate according to a detection result, controlling the AC/DC selection circuit to be connected with the AC power supply circuit after determining that the object to be heated is a detachable heating plate according to the detection result, and controlling the AC/DC selection circuit to be connected with the DC power supply circuit when determining that the object to be heated is not a detachable heating plate according to the detection result, thus the detection control circuit cannot use an alternating current provided by the AC power supply circuit for heating the detachable heating plate normally. By adopting the heating control device, the heating control method and the cooking appliance, the safety of a user using the cooking appliance can be effectively ensured.

Description

technical field [0001] The present invention relates to the technical field of household appliances, and more specifically, to a heating control device, a heating control method and a cooking utensil. Background technique [0002] At present, after the detachable heating plate in the cooking appliance is used to heat the object to be heated, when the detachable heating plate is removed from the cooking appliance, at this time, the two terminals of the AC / DC selection circuit connected to the detachable heating plate or The movable contact electrode of the AC / DC selection circuit will be exposed on the outside, because the movable contact electrode is connected to the AC, and the voltage of the AC is very high, so if the user accidentally touches the movable contact electrode or the two terminals of the AC / DC selection circuit, Will get an electric shock, and pose a threat to the personal safety of the user, thereby reducing the user experience. [0003] Therefore, when the ...
