l electric kettle why noise

Electric kettles tend to produce loud noises in the process of boiling water. In the process of heating, mainly due to uneven heating vibration and bubble burst noise. Conventional heating disc assembly is composed of stainless steel chassis, thermal conductive aluminum plate and heating tube welding, welding process has a great impact on the production of heating disc assembly, and the three heat transfer efficiency is limited, especially after the water temperature reaches more than 60 ℃, the corresponding heat conduction area above the heating tube is easy to gather formed bubbles. Among them, large bubbles are easy to escape from the chassis when heated, and a large number of small bubbles are generated and the noise formed by the rupture is very loud. This noise is unavoidable, but can it be reduced by improving the production process?

l  the electric kettle on market at present is how to reduce the noise?

At present, most electric kettles on the market are treated to reduce noise by coating the heating layer with hydrophobic coating or adding the corresponding structure, but the noise reduction or sound insulation effect of this way is limited.

What silent electric kettle are out there? Rossell Hobbis, Argos,Sunbeam and other brands have silent electric kettles.

l what is the noise standard electric kettle?

The maximum allowable noise level is 70 decibels, and above 70 decibels, human hearing is affected. Long term strong noise, people will be unstable blood pressure, loss of appetite, and cause neurasthenia, weight loss, etc.

l how to reduce the noise of household electric kettle

1. Use electric kettles scientifically. The electric kettle should be at least 1 meter away from the rest and work place of human body when used. Electric kettles and other household appliances should not be placed too close to each other, the closer the distance is, the greater the noise. The electric kettle should not be placed against the wet wall, but should be placed smoothly.

2. Use electric kettles correctly. Use citric acid in time to clean the residual scale in the electric hot water kettle, and do the daily maintenance of the electric kettle.

3. The accessories on the electric kettle should be fastened well, all kinds of screws should be tightened in time, and the fault should be repaired in time.

l electric kettle is it necessary to have a silent feature or the -quiet boil feature?

1. The price of silent electric kettle on the market is generally relatively high, much higher than that of ordinary electric kettle.

2. It takes a short time for an electric kettle to boil a pot of water. Let's take the boiling time of a 1.7L electric kettle as an example. 1.7L electric kettle works under the high power of 1850-2200W, and it only takes about 5 minutes to boil a pot of water. If it is 2500-3000W, it takes even less time to boil water, about 3 minutes. For such a short time, and with most kettles operating at a noise level of around 70DB, the noise has little effect on hearing. In such a short period of time, the noise may have died down before users even noticed it.

l silent electric kettle really silent?

Noise is unavoidable, and almost everything in the world that moves, electric kettles are no exception. By adding heating coating or metal structure, most brands of Silent electric kettle can reduce the noise by 25%-30% to some extent, but this cannot achieve a good effect of silent boil. If the noise is reduced by 25% to 30%, the boiling water business will still be about 50 decibels, equivalent to the sound of a heavy rain.
