Abstract

The invention relates to an induction cooker capable of measuring temperature. The induction cooker comprises a panel, an electromagnetic heating coil and a control circuit and is characterized in that at least one positive temperature coefficient temperature sensor pattern is printed on the upper surface of the panel so as to realize contact with a heated pot, a first coil is printed on the panel by conductive slurry, the first coil is electrically connected with the positive temperature coefficient temperature sensor, and the induction cooker further comprises a second coil magnetically coupled to the first coil and a processing circuit electrically connected between the second coil and the control circuit.

Description

technical field [0001] The invention belongs to a cooking utensil, and relates to a kitchen utensil classified in A47J; a coffee mill; a spice mill; and a beverage preparation device. Background technique [0002] The induction cooker uses the coil plate to generate an alternating magnetic field under the action of the control circuit, and generates a large amount of dense pot current through the magnetically conductive (iron) pot. The eddy current makes the iron atoms of the pot move at high speed and irregularly, and the atoms collide and rub against each other to generate heat. Extremely energy efficient. [0003] Using the induction cooker to heat pots and utensils for cooking and boiling water can complete most of the cooking tasks in the family, and it has more and more penetrated into people's lives. [0004] The temperature detection of the existing induction cooker is mostly contact temperature detection, relying on the thermistor installed in the center of the inn...
