00:00Unexpectedly, this seemingly simple electric kettle contains exquisite physical design.

00:08Today we will explore its internal structure and working principle.

00:11There are two main parts of the kettle.

00:13One is the switch on the top, which is also called the temperature control.

00:17The other is the heating component located at the bottom of the kettle or the steam switch,

00:22which is also the core part of the kettle.

00:25Resistance coils are usually used to convert electrical energy into heat energy.

00:29These resistance coils are usually made of high-temperature materials such as iron or

00:34nickel-chromium alloy.

00:36In addition, the kettle is also equipped with another key switch called the anti-dry switch.

00:42Its principle is similar to the steam switch on the top.

00:45Let's first take a look at the steam switch on the top.

00:47Its core part is a dish-shaped metal sheet.

00:50Here is a key knowledge point.

00:52This sheet is actually made of two different metals, usually iron and copper.

00:56The thermal expansion rates of these two metals are very different, but they have similar

01:01mechanical elasticity, which means that they will stretch and bend to varying degrees during

01:07the process of thermal expansion and contraction.

01:10When these two metals are laminated together and the temperature reaches a certain level,

01:14the metal piece with a high coefficient of thermal expansion will bend more than the

01:18one with a low coefficient of thermal expansion, causing the overall bending toward the lower

01:23side.

01:24With this in mind, let's go back to the kettle switch.

01:27When the water in the hot water kettle boils, a large amount of water vapor is generated.

01:32It enters the disk-shaped bimetal piece through the small hole at the bottom.

01:36The arrival of the steam causes the temperature of the metal piece to rise rapidly.

01:41Once it exceeds a certain value, the metal piece will bend and deform.

01:45There is a gap above the metal piece.

01:48There is another cylinder at the rear wire contact point of the cylinder.

01:52When the metal sheet is bent, the front cylinder will rise.

01:55Under the action of the lever, the rear cylinder will press down, causing the circuit wire

02:00contact point to disconnect, thereby stopping heating.

02:03The principle of the bottom anti-dry boil switch is similar to this but slightly different

02:09in structure and triggering temperature.

02:11The triggering temperature of the steam switch is usually around 100°C, while the triggering

02:16temperature of the anti-dry switch is higher.

02:19Circuit is usually triggered when the bottom is overheated.

02:22As shown in the picture, there is a piece of metal connected to the metal sheet.

02:26Once the cylinder overheats, the metal sheet begins to deform and bend downward, thus pushing

02:31down the wire contact piece under the cylinder and disconnecting the circuit.

02:36This means that the kettle's protection mechanism is successfully executed.

02:40In addition, the bottom of the kettle is also equipped with a small LED indicator light,

02:45which is connected to the main circuit connection.

02:47When heating, the indicator light lights up.

02:50When the circuit is interrupted, it goes out.

02:52Finally, let's take a look at the lid of the hot water kettle.

02:55The lid will open with just a slight press.

02:58This is because there is a special device inside the lid.

03:01The front end is stuck in the mouth of the pot.

03:03The rear end is connected to a spring.

03:05When the lid is buckled, the spring remains released.

03:08When the button is pressed, the spring is compressed.

03:11The front buckle is released to open the lid.

03:14In fact, the structure and working principle of the hot water kettle are not complicated.

03:18But it is not easy to design a tool that can benefit millions of families with such a clever

03:23combination.
