Bella Cucina Mini Cupcake Maker 13465 Disassembly

简介

Use this guide to systematically disassemble the Bella Cucina Cupcake Maker 13465, manufactured by SENSIO INC. The main components such as the heat fuse, heating elements, LEDs, and wires that make the device function can be observed after the disassembly. Moreover, an electric schematic diagram for the device can be created based on the observations.

The heating elements can become quite hot. Therefore, make sure to unplug the device from the power supply and allow it to sufficiently cool down, before starting the disassembly. Also wear hand gloves, because the metal alloy surfaces can be greasy.

步骤 7

The device does not have any switch. It turns on automatically when the power cable is connected to a 120 volt AC supply. It has a power rating of 710 Watts.
The current passes through the heat switch before going through the two heating elements.
Both the green and orange LED light up when the device is working. However, the heat switch opens if the temperature becomes very high (exceeds 165 degree Celsius).
Therefore, current stops flowing through the heating elements to prevent any accident.
When the fuse melts, only the orange LED will remain on , indicating that the heating elements have been shut off.
