Preset Outage Timer of Electric Cooker Remote_Control

The figure illustrates a preset outage timer circuit designed for an electric cooker. The timing range of the circuit extends from 1 hour to 12 hours, adjustable via a potentiometer (PR). The timing mode operates on a counting basis, and the control method is preset outage timing. The circuit utilizes a BT33 component to generate trigger signals for the thyristor (VS). When the BT33 ceases to operate, the thyristor (VS) will turn off.

The electric cooker preset outage timer circuit is engineered to provide a reliable timing mechanism for cooking applications. The core of the circuit is the BT33, a device that functions as an oscillator or timer, producing a series of trigger pulses. These pulses are essential for controlling the thyristor (VS), which acts as a switch to manage the power supply to the electric cooker.

The adjustable potentiometer (PR) allows the user to set the desired cooking duration between 1 and 12 hours. This flexibility is crucial for various cooking needs, enabling the user to select the appropriate time based on the type of food being prepared. The counting mechanism ensures that the timer accurately tracks the elapsed time, providing a straightforward and efficient user experience.

When the BT33 is operational, it continuously emits trigger signals at a defined frequency. These signals are fed into the gate of the thyristor (VS), which remains in the 'on' state, allowing current to flow and power the electric cooker. Once the preset time elapses, the BT33 stops generating signals, leading to the thyristor turning off. This action effectively cuts off the power supply to the cooker, preventing overcooking or burning of food.

The circuit design may also include additional components such as resistors, capacitors, and diodes to support stable operation and prevent voltage spikes that could damage sensitive components. Proper layout and thermal management are crucial to ensure the longevity and reliability of the circuit, especially in high-temperature cooking environments.

In summary, this preset outage timer circuit for electric cookers combines functionality and ease of use, allowing users to set precise cooking times while ensuring safety through automatic power disconnection.As shown in the figure is a preset outage timer of electric cooker circuit.
