1. Working Principle of a Cooker Thermostat:
A cooker thermostat operates on a simple yet ingenious principle. It consists of a temperature-sensing element, such as a bimetallic strip or a temperature probe, and a control unit. The temperature-sensing element expands or contracts in response to changes in temperature. This action is then transmitted to the control unit, which adjusts the heat output accordingly to maintain the set temperature.
The temperature-sensing element in a cooker thermostat can have different designs, including a bimetallic strip. A bimetallic strip is composed of two dissimilar metals bonded together, each having different coefficients of expansion. When heated, these metals expand at different rates, causing the strip to bend. This bending action is utilized to activate or deactivate the heating element in the cooker.
Another type of temperature-sensing element is a temperature probe, which directly measures the temperature inside the cooking chamber. This probe is usually located in a strategic position, such as near the heating element or in the center of the cooking area. The probe sends signals to the control unit based on the measured temperature, allowing it to modulate the heat output effectively.
