[0019] See also Figure 1-Figure 3 A ceramic device that can be used for induction cooker heating includes a ceramic pot 1, which includes a ceramic layer 101, a magnetic conductive sheet 102 is fixedly connected to the bottom of the ceramic layer 101, and a metal layer 103 is fixedly connected to the surfaces of the ceramic layer 101 and the magnetic conductive sheet 102.

[0020] Furthermore, a card block is provided on the top of the magnetic conductive sheet 102 , and a card slot used in conjunction with the card block is provided on the bottom of the ceramic layer 101 .

[0021] When the ceramic layer 101 is fired to 1200°C and softened, the internal slot shrinks to fix the block, so that the magnetic sheet 102 and the ceramic layer 101 fit tightly together. In addition, the magnetic sheet 102 is located at the bottom of the ceramic layer 101 and can be supported during the softening process to achieve the effect of preventing deformation.

[0022] Furthermore, the metal layer 103 includes a bonding layer 104, which is fixedly connected to the surface of the ceramic layer 101, and a thermal conductive layer 105 is fixedly connected to the surface of the bonding layer 104. A plurality of thermal conductive channels 106 are provided inside the thermal conductive layer 105. A thermal insulation layer 107 is fixedly connected to the surface of the thermal insulation layer 107, and a heat-resistant and anti-corrosion layer 108 is fixedly connected to the surface of the thermal conductive layer 105.

[0023] Furthermore, the bonding layer 104 , the heat-conducting layer 105 and the heat-insulating layer 107 are fixedly connected to the surface of the magnetic conductive sheet 102 .

[0024] Furthermore, a heat conducting liquid is provided inside the heat conducting channel 106, and the material of the heat conducting liquid is silicone oil.

[0025] Furthermore, the bonding layer 104 is made of copper, and the thermal conductive layer 105 is made of aluminum.

[0026] Furthermore, the material of the thermal insulation layer 107 is steel, and the material of the heat-resistant and anti-corrosion layer 108 is metal ceramic coating.

[0027] Furthermore, a handle 2 is fixedly connected to the surface of the ceramic pot 1. By providing the handle 2, the ceramic pot 1 can be easily held.

[0028] The magnetic sheet 102 is located at the bottom of the ceramic layer 101. When placed on the induction cooker, the magnetic sheet 102 will be affected by the magnetic field generated by the induction cooker to generate eddy currents, thereby generating heat. The bonding layer 104 is made of copper. Copper has excellent thermal conductivity and can quickly conduct heat to the ceramic layer 101. In addition, copper has a low hardness and can fit tightly with the ceramic layer 101. The thermal conductive layer 105 is made of aluminum. Aluminum also has good thermal conductivity and is provided with a thermal conductive channel 106 inside. The silicone oil filled in the thermal conductive channel 106 can flow during heating, further helping to evenly distribute heat in the thermal conductive layer 105, and can quickly conduct the heat generated by the magnetic sheet 102 to the bonding layer 104.

[0029] The insulation layer 107 is made of steel. Steel has a certain heat capacity and can store heat and maintain a stable temperature in the pot for a short period of time. The existence of the insulation layer 107 reduces heat loss and improves heating efficiency. The heat-resistant and anti-corrosion layer 108 is made of metal ceramic coating, which can not only protect the internal structure from corrosion, but also improve the heat resistance of the surface, so that the entire device can still maintain a good working condition at high temperatures.
