Why the kettle is noisy during operation?
Source:Kettle during operation tends to make noise.
Have you Noticed ever that an electric kettle is very while working? Of course I notice, because to ignore it is impossible. It is possible that you even wondered why this happens. When the water is almost boiling, the sound becomes quieter than a few seconds after switching on. There's a very logical explanation as to why the kettle on the stove works differently and the noise starts only when the water is almost boiling.
First, let's define what an electric kettle is different from the usual that even our grandparents boiled water on a gas stove.
At the heart of the kettle heating element lies. It is located at the bottom of the kettle and is heated through . At the dawn of the appearance of electric kettles heating element had a different form. For a long time was used, similar to a boiler. It had the form of a spiral and coping with their tasks. Then it's time flat heating element, and a lot has changed.
The Design is simplified, and the water began to heat up faster. Here lies the first and main cause of the noise during boiling.
Why kettle noise?
Modern kettles have a capacity of several kilowatts, to the time we want a Cup of hot tea, to the moment we receive it, it took as little time as possible. It was said above that the heating element is at the bottom, and this means that water heating is uneven. That is, when the water in the lower part of the tank already came into contact with the hot surface, the top still stays cold.
At this point, the gas in the water begins to expand and turn into air bubbles. These bubbles begins to rise up. When they reach the cold layer, they begin to collapse by reducing the gas temperature in the colder a liquid medium.
At this point, the vial and . When these bubbles a lot, barely audible cotton turns into a hiss, then the hum that accompanies a boiling kettle. Later the sound becomes more loud bangs, which is a lot, but at the same time, they become quieter.
At this point the water begins to boil and bubbles reach from the bottom to the surface, causing the water to boil. After some time the kettle off and we can use the boiling water.
a kettle for the stove is quieter electric.
Theoretically, to avoid hissing during operation of the kettle is possible. For this it is necessary to stir the water so it heated more evenly and was not the most bubbles that collapse, rising to the top. Only if you want to try it, be careful. Steam is very hot and the appliance connected to the socket.
Another way to get rid of the noise will be the choice of a less powerful kettle or select a weaker heating mode, if your model allows it.
You may Also notice that the kettle is on so not much noise and the main sound starts at the moment when the water is boiling. At the same time because it starts to sound a whistle, located on the body (if any). It is connected with the fact that the water in the kettle on the stove heats up slower. And does not produce situations where some of the water already boiling, and some still remains cold.
Personally, I'm boiling the kettle only annoying in the moment when I turn it on later in the evening. The rest of the time to endure the noise for a couple minutes does not cause me any discomfort. I choose a more rapid boiling, with greater noise, and not Vice versa.
Bother you the noise of the kettle or it can fail if the water boils fast?
