The kettle doesn t ring, and it s not good to fix it

The reason for not ringing: the newly bought kettle, while it is sound after boiling water, but after a long time, the lid of the kettle is a little loose, and the whistle parts inside are misplaced, and the position picked at the factory has changed, and there will generally be no sound or not loud situation.

How to repair it? It is divided into the following steps:

1. Disassemble the internal and external components of the kettle lid, friends who are not familiar with the structure must remember the original position of each component, such as the whistle structure of the kettle can also be drawn.

Second, then open the component, clean the dirt around the spring piece, generally there is scale to block the air hole!

3. After cleaning, adjust the position of the three spring blades of the whistle so that the side with rivets is facing the inside of the pot, and then the horizontal direction of the three spring blades is parallel to the three exhaust holes of the small cover outside the pot lid to keep the air flow through.

Fourth, finally tighten the screws, at this time, do not make the original adjusted components misaligned because of screwing. In this way, the sound will generally be normal, if it still does not sound, its relative position should be fine-tuned according to the above method and position.

See if the lid is clogged.

"The secret of the whistle is on the lid of the kettle. On the inside of the lid, a disc with several reeds on it (right, similar to a reed in a harmonica), and then this disc with reeds is placed on the inside of the lid directly opposite the handle of the lid, and several slits are made around the handle of the lid so that the air can flow through the reed and rush out of the slit.

When water boils, a large amount of water vapor is generated, and this high-pressure water vapor passes through the reed inside the lid and then rushes out through the slit around the lid, causing the reed to vibrate and make sound as it passes through the reed. Since the reed is certain, all, regardless of the amount of water in the pot, after boiling, the tone of the whistle is the same. In addition, in order to allow the steam to flow through the reed slit as much as possible, there is also a lid at the spout that can be used to cover the spout when boiling water.

There are several possible reasons why the kettle does not sound its horn:

1. The lid of the pot is not covered properly, resulting in air leakage, and the air pressure in the pot is insufficient, resulting in the whistle not sounding;

2. The water in the pot is too high, and there is not enough space to generate water vapor pressure, resulting in no whistle.

If there are no of the above two cases, consider the problem of the horn itself

1. See if the horn is deformed, and if it is deformed, it should be restored;

2. The distortion of the phoenix film will also cause the whistle to not sound, so you can correct it.

Before boiling water, pay attention to press the lid on the spout with your hand to make sure the lid is tight. Then check the reeds on the lid of the pot to see if there are any problems with the reeds being stuck, rusting, or breaking. If the air hole is blocked, clean it up.

If the reed is broken, it needs to be replaced. Finally, look to see if the screws on the reed are tightened. When you're done, boil another pot of water and try it.

The kettle should ring this time. If it still doesn't work, then it's better to find a professional master to repair it.

Do you troubleshoot it, dear?

1. The electric kettle is broken but the power switch is normal: if the power switch is normal, the fault mostly occurs in the insulation switch. First of all, see whether the reed of the bimetal sheet is pressed against the switch contact rod, if it is pressed too tightly, you can use tweezers to bend it upwards until the distance between the two.

If the distance between the bimetal sheet and the switch lever is normal, the switch box should be disassembled, and the contacts and reeds of the insulation switch should be cleaned and repaired.

2. It is not heated after power-on, but the indicator light is on: the indicator light is on, indicating that the power supply has been added to the indicator circuit, and the fault is in the electric heating pipe or its connecting part, and the electric heating pipe is damaged and the contact is poor. Remove the electric heating pipe and measure its resistance value.

The electric heating pipe is damaged and can generally only be replaced. The poor contact is mainly due to the serious corrosion or deformation of the contact reed in the power plug assembly, which can be disassembled and repaired by the switch box, and it is best to replace it with a new one if the damage is serious.

3. Water can not boil, can not cut off electricity: mainly caused by the failure of the reset switch. Common reasons are severe deformation of the thermostat or obstruction of the operation of the switch linkage.

For the former, the convex angle of the small tongue of the thermostat can be rebent to make it push the switch connecting rod normally. For the latter, it is necessary to find the obstructed part or foreign body, which can generally be restored to normal by removing the foreign body and correcting the position.

4. Slow heating speed: The common reason is that the power supply voltage is too low, and the indoor power supply line or plug socket is not in good contact, which should be eliminated first. Then check whether the electric heating pipe is seriously fouled, whether the contact between the base and the power plug holder of the pot body is seriously bad, etc.

If the electric heating pipe is fouled, you can scrape it with a knife first, and then polish it with fine sandpaper.

If the contact between the base and the power plug holder of the pot body is seriously poor, you can first remove the oxide layer and dirt of the contact piece and contact of the plug holder, and then correct its shape to make the contact between the two close and good.

When the water begins to heat, the bottom of the kettle produces some small bubbles, these small bubbles are mainly formed by the air adsorbed at the bottom of the kettle and dissolved in the water In addition to the air in the bubble, it also contains the water vapor produced by heating, with the increase of temperature, the water vapor evaporated into the bubble gradually increases, its volume and pressure will increase, and it rises from the bottom under the action of buoyancy When the bubble rises to a lower temperature, part of the water vapor in the bubble condenses into water, and the pressure outside is stronger than the pressure in the bubble, at this time, the volume of the bubble gradually decreases

In the process of continuing to heat, the bubbles are produced and expanded more and more, and they are getting bigger and bigger, but when the bubbles rise to a lower temperature, the water vapor in the bubbles will condense into water, and the volume will gradually decrease In such a process, as the temperature rises, the volume of the bubbles expands and shrinks for a while, and constantly floats, which will produce a kind of vibration If the frequency of this vibration is the same as the natural frequency of the kettle, it will resonate and make a sound In addition, there are still bubbles running out of the water. If the pressure of the gas in the space where there is no water in the pot increases, a part of the gas will be squeezed out of the gap between the lid and the body of the pot, and a sound will also be generated, and as the temperature rises, the bubbles running out of the water surface will increase, and the air pressure will continue to increase, and the sound will become louder and louder

For these two reasons, we hear the sound of water, and the sound of water is getting louder and louder, which is made when the water is not yet boiling, and it is generally "hum, hum, hum......Voice

When the water at the bottom layer is heated to 100 degrees, the water vaporizes into water vapor, forming bubbles to rise, and when the water temperature in the upper layer is low, the bubbles cool, liquefy, and quickly condense into liquid water, and the bubbles will make a sound when they shrink sharply. This is the reason why the water makes a sound before it boils. When the water is boiled, the bubbles can rise all the way to the top without liquefiing, and only the sound of boiling water can be heard.

This one has nothing to do with the electric kettle. When the temperature of water rises, the friction of water molecules will gradually increase, a large number of water molecule friction produces friction noise, the spout of the kettle is generally smaller, plus the space above the water surface in the kettle, the sound is amplified, and once the water temperature reaches 100 degrees, that is, the water is boiled, the water changes from liquid to gaseous, generating water vapor, and the sound is naturally small without friction.

After the electric hot water pot is connected to the power supply and heated, the water temperature gradually rises to 100 degrees, the water begins to boil, and the steam hits the bimetal sheet on the steam switch. If the steam switch fails, the water in the pot will continue to boil until the water is boiled dry, and the temperature of the heating element rises sharply. Therefore, the safety protection device of the electric kettle is:

The design is very scientific and reliable. This is the principle of triple safety protection of electric kettles.

The working principle of the electric kettle is as follows: the bimetal sheet of the steam temperature sensing element is deformed by using the water vapor generated when the water is boiling, and the power switch is pushed by the principle of the bar through the deformation, so that the electric kettle will automatically power off after the water is boiled. It is not self-resetting when it is powered off, so the kettle will not automatically reheat after the power is off.

If your kettle keeps ringing, it means that the water is in the process of boiling! In other words, the process of boiling water is gradual, of course, until it boils.

The reason why the kettle keeps ringing is because when the water is about to boil, there is gas hitting the whistle-like thing on the top of the kettle, and it will make a sound, which is caused by the air current.

Generally, the kettle keeps ringing, indicating that there may be a problem with some parts of the kettle, which will cause an air flow to pass through and make a sound.

It's a design problem at all, only the electric kettle is particularly loud! As soon as it was lit, it started to ring, and it should be that the heating process of the coil affected the gas in the water. But ordinary natural gas, the sound of boiling water over an open fire is very small, and it is nonsense to say that the sound is the same.

Is the water too full, or too little water, see if the power is normal, check more.

The whistle of the kettle does not sound, the general situation is because there is too much scale condensed on the reed of the flute, soak the reed with vinegar, or soak it with diluted oxalic acid and other cleaning agents, and clean the scale on the reed to return to normal.

Check that the lid of the kettle is tightly closed. If the water is not covered tightly, the kettle will not ring. Check the reed on the lid of the pot for any problems with the reed being stuck, rusting, or breaking, clean it if the air hole is blocked, and replace it if the reed is broken.

When the water is boiled, a large amount of water vapor is generated, and these high-pressure water vapors pass through the reeds in the lid and rush out through the slits around the lid, causing the reeds to vibrate and make sound as they pass through the reeds. Since the reed is certain, the tone of the whistle is the same after boiling, regardless of the amount of water in the pot. In addition, in order to allow the steam to flow through the reed slit as much as possible, there is also a lid at the spout that can be used to cover the spout when boiling water.
