Electric kettle connected to the power supply heating, the water temperature gradually rose to 100 degrees, the water began to boil, the steam impact steam switch above the bimetal, due to thermal expansion and contraction of the role of the bimetal expansion and deformation, the top switch contacts to disconnect the power supply. If the steam switch fails, the pot of water will continue to burn down until the water is burned dry, the temperature of the heating element rises sharply, located in the bottom of the heating plate has two bimetal, because of the role of heat conduction temperature rises sharply, expansion and deformation, disconnect the power supply. Therefore, the electric kettle safety protection device is designed to be very scientific and reliable. This is the electric kettle triple safety protection principle.

1, what is the working principle of the electric kettle, why the water can automatically disconnect?

      The working principle of the electric kettle: the use of water vapor produced when the water boils to make the steam-sensing element of the bimetal deformation, and the use of deformation through the leverage principle to promote the power switch, so that the electric kettle in the water boiled automatically power off. Its power failure is not self-resetting, so the kettle will not automatically reheat after power failure.

2, what is the electric kettle triple safety protection device?

       The first: steam switch, when the water boils steam switch will act to disconnect the kettle; Second: dry burning protection, such as the steam switch does not act, the water will keep burning and constantly reduced, when the water is below the minimum water level or dry, another temperature control on the bimetallic sheet will act to disconnect the kettle; Third, such as the above have lost their role, as the temperature rises, the thermostat within a plastic pusher will be melted to disconnect the kettle. Power off.

3, the electric kettle according to the shape of the structure of those classified?

      According to the structure is divided into straight and rotary. Directly inserted is the kettle body and base can not be rotated, with the heater directly heated; rotary is the kettle body and base can be rotated 360 degrees, with the heating disk heating. Most of the common products on the market for the rotary type.

4, why some electric kettles have fragrance, fragrance is not high-grade?

      Scented electric kettle is in the sealing silicone with fragrant substances, so open the lid will smell a fragrance, scented surface feel good, but in fact, human health is not good, so there is a scented electric kettle is just a number of small brands to lure consumers to buy the surface. Good kettle should not have any flavor, including plastic flavor. The plastic part of the water must be food-grade plastic, and food-grade plastic is no flavor.

5, why is the electric kettle used for a period of time after the heating will be noisy? Is it a problem with the product?

      Boiling water noise is because the electric kettle produces more scale, heating will produce a large number of bubbles, bubbles in the process of rising burst and sound. This phenomenon is not only not a product problem, on the contrary, it is a reminder of the cleaning and descaling. Consumers can be cleaned in accordance with the instructions to eliminate the phenomenon of descaling.

6, the electric kettle power line is designed too short, inconvenient to use, is not the manufacturer in order to save costs ah?

      Electric kettle belongs to the larger power products, if the power cord is too long will be unsafe. Regular manufacturers of power cord length are in strict accordance with national standards. Out of consumer safety considerations, the regular manufacturers will not be easy to follow the convenience of consumers and arbitrarily unlimited length of the power cord, so as not to bring hidden safety hazards to consumers. Of course, too short also not. Therefore, the power cord short decision may not be to save costs.

7, electric kettle can cook noodles in the north?

      Although the principle of cooking noodles and boiling water is almost the same principle, but the electric kettle can never cook noodles. Because cooking noodles is a long time to open the lid, it is easy to make the water vapor through the lid backflow to the temperature sensor, so that the thermostat can not automatically trip and accidents.

8, why the same stainless steel kettle on the market, the price is very different?

      In fact, consumers say “the same” stainless steel is only the same on the surface, in fact, the same stainless steel products are very different in nature: 1. stainless steel parts are imported excellent material, imported and domestic prices vary greatly; 2. even with the same stainless steel materials, processing procedures are not the same, the cost is much higher! Even with the same stainless steel materials, processing procedures are not the same, the cost is much higher, such as near light, mirror light is a big difference; 3. thermostat is imported or not, the cost price difference of twenty or thirty dollars. Therefore, you roughly see the so-called same stainless steel body, in fact, take a closer look, there is a big difference, a penny a penny.

Nine, some electric kettle with insulation, insulation principle is what, insulation when power consumption?

      Kettle with thermal insulation, most of the two heating tubes, there is a thermal insulation heating tube is controlled separately through the thermal insulation switch, which allows the user to control the choice of whether or not to continue to keep warm in order to achieve a certain amount of time, but still keep the water temperature at the right temperature can be brewed tea, soak noodles and so on. Thermal insulation is generally below 100W, an hour usually consumes no more than 0.1 degrees of electricity.

10, what is the key component of the electric kettle?

      The key component of the electric kettle is the thermostat, the thermostat's good or bad and service life determines the kettle's good or bad and service life.
