How does a cordless electric kettle work
The working mechanism is an integral part of the cordless electric kettle. An electric kettle has numerous integral elements that help it in the execution of its roles. You need to understand the different parts to comprehend its working principle and how the different parts relate.
Below is a breakdown of the different parts of cordless electric kettles.
A. The Heating Element
The heating element is the heart of a cordless electric kettle, responsible for heating the water to its boiling point. It is typically made of materials like stainless steel or ceramic, known for their excellent heat conductivity.
When you turn on the kettle, the heating element converts electrical energy into heat. This heat is then transferred to the water, rapidly raising its temperature. As the water reaches its boiling point (100°C or 212°F), bubbles form and rise to the surface, resulting in a rolling boil.
B. Water Reservoir and Capacity
The water reservoir is where you pour the water to be heated. It comes in various capacities, ranging from 1 liter to 1.7 liters, to accommodate different needs. It’s essential not to overfill the kettle, as doing so might cause spills and compromise safety. The heat from the metal coil is transferred to the water reservoir to the water.
Once the water reaches its boiling point, the boiling stops. The electric kettle has an auto shut-off function that prevents heat transfer to the water reservoir once the water is boiled. This saves on energy.
C. The Base and Power Supply
The base of the cordless electric kettle serves multiple functions. Firstly, it houses the heating element, which connects to the power supply. Secondly, the base provides a stable platform for the kettle to sit on while boiling the water.
When placed on top, the base has power contacts that connect to the kettle. These contacts facilitate the transfer of electrical energy from the base to the heating element in the kettle. The cordless design allows the kettle to be lifted easily, and the absence of a cord makes it more manageable and safer to use.
The below video illustrates how cordless electric kettle works with an elaboration of various components.
Cordless Kettle Design
The unique design of cordless electric kettles contributes to their portability and ease of use. This design revolves around the detachable feature differentiating them from corded electric kettles.
The kettle sits at the base, where the heating element is located. When boiling water, the kettle sits on the base and draws power from it. The base has a knob in the center. It also has a cord that you plug into an electrical outlet with a metal heating coil sealed inside the base.
The circuit is completed by placing the water reservoir on the base, and power is supplied to the base when you turn on the electrical outlet.
Once you have switched on the electrical power, you must flip the knob at the kettle’s base. This heats the metal coil inside the kettle. The heat is transferred to the water reservoir and into the water.
After the water is boiled, you can lift the kettle off the base for serving without being confined by a cord. This convenient feature makes cordless electric kettles ideal for various settings, such as offices, kitchens, dorms, and outdoor activities like camping.
The cordless electrical kettle’s water reservoir is not attached to anything. The implication is that you can conveniently pick it up from the base, walk to other parts of your house, and serve the hot beverage you have boiled.
You can set the kettle back to the base once you are finished. However, the base will not continue to produce like with the corded kettles, which makes it a safer unit coupled with energy efficiency.
Electric Kettle Temperature Control
Temperature control in an electric kettle is facilitated with various elements integrated into the kettle system. One such element is a temperature sensor. At the kettle’s base is a temperature sensor to measure the water temperature. This can be a simple bi-metallic strip or an advanced electric sensor, depending on the design of your kettle.
Besides, the kettle has a thermostat to sense the water temperature and control the output of the heating element. The thermostat helps you regulate the temperature to your desired level.
Once you have put water to the desired level in the reservoir, you need to turn on the kettle, and the heating element will heat the water. As the temperature of the water increases, the sensor detects this temperature rise.
The electric kettle’s temperature control system is pre-programmed with specific temperature settings. The settings may include the boiling point of water (100 (100°C or 212°F) or other temperature levels suitable for beverages like coffee or tea.
Once the temperature sensor detects that the water has reached the desired temperature, the thermostat cuts off the power to the heating element, preventing the water from boiling further, and maintains the water at the set temperature.
If the kettle has a “keep warm” feature, it will periodically turn on the heating element to maintain the water temperature at the desired level. The thermostat will monitor the water temperature and activate the heating element to keep the water warm.
Generally, the temperature control mechanism allows users to heat water to specific temperatures for various purposes, making it convenient to brew different types of beverages or perform other tasks requiring precise water temperatures.
