As shown in fig. 2-9, the heat generating component 1102 includes a heat transfer plate 100, a carrier plate 200, and a fastener 300. The tray 200 is substantially bowl-shaped for holding food material, and the tray 200 is disposed above the heat transfer plate 100. The heat transfer tray 100 is provided with a heating member 110, the heat transfer tray 100 is used for transferring heat generated by the heating member 110 to the object carrying tray 200, and the temperature of the object carrying tray 200 is increased to heat the food material carried on the object carrying tray 200. The fastening member 300 is mounted to the carrier tray 200 and the heat transfer tray 100, and fastens the carrier tray 200 and the heat transfer tray 100.

The tray 200 is made of a different material from the heat transfer tray 100. In this embodiment, the material of the carrying tray 200 is steel, and the carrying tray 200 made of steel material has high strength and is not easy to react with food materials, thereby being beneficial to the edible safety of users. The heat transfer plate 100 is made of aluminum, and the aluminum material has good heat conductivity, so that the heat transfer plate 100 can transfer heat to the object carrying plate 200 to increase the temperature of the object carrying plate 200.

The thermal expansion coefficients of the object carrying tray 200 and the heat transfer tray 100 made of different materials are different, so that when the food processor heats food, the temperature of the object carrying tray 200 and the heat transfer tray 100 rises, and the object carrying tray 200 and the heat transfer tray 100 are deformed relatively, so that the object carrying tray 200 and the heat transfer tray 100 are easily separated and cracked due to the tensile force between the object carrying tray 200 and the heat transfer tray 100. By providing the fastening member 300, the fastening member 300 applies a force to the carrier tray 200 toward the heat transfer tray 100, so that the connection of the carrier tray 200 and the heat transfer tray 100 is more stable. When the temperatures of the heat transfer tray 100 and the tray 200 are increased, the heat transfer tray 100 and the tray 200 are not easily separated and cracked due to the fastening of the fastening members 300, so that the heat on the heat transfer tray 100 can be effectively transferred to the tray 200, and the food materials carried on the tray 200 can be heated. Meanwhile, by means of the arrangement, the service life of the heating component 1102 is prolonged.

In this embodiment, the fastener 300 is a bolt or stud and the fitting 700 is a nut.

Of course, in other embodiments, the fastening member 300 may be a screw, and in this case, the fitting member 700 is not required to be disposed, and the screw is only required to be inserted into the carrier tray 200 and the heat transfer tray 100 to fasten the two. Alternatively, the fastener 300 is not either a screw or a bolt, and the fitting 700 does not need to be provided. The fastener 300 may have two opposite abutting portions and a fastening portion connecting the two abutting portions, and the fastening portion may be configured to drive the two abutting portions to move towards each other. The two abutting parts are respectively arranged on the outer surfaces of the object carrying tray 200 and the heat transfer tray 100, and the fastening parts apply opposite acting forces to the two abutting parts, so that the fastening parts clamp the object carrying tray 200 and the heat transfer tray 100, and the object carrying tray 200 and the heat transfer tray 100 are fastened.
