How to choose the principle of electric kettle with high cost performance

Everyone will consider the price/performance problem when selecting products, and it is no exception when buying electric kettles. How should we choose a cost-effective electric kettle? What are the special things to pay attention to? Let's take a look at it with Xiaobian.

How to choose a cost-effective electric kettle

Temperature controller

The thermostats used in electric kettles on the market mainly include imported and domestic.

Imported thermostats are mainly Otter and Strix brands, both of which are from the UK. Among them, Otter thermostat is the earliest temperature controller brand for producing household appliances. It is mainly used for high-end brand electric kettles. It can provide six-fold safety protection. Its temperature control products have been widely used in famous brands such as Mercedes-Benz and BMW. use.

Selected capacity

According to the usage habits and actual needs, the capacity of the electric kettle can be selected. For example, a family of 3 to 4 people can choose a 1.5L electric kettle.

Material selection

In general, the current electric kettle body on the market has two materials: stainless steel and PP. The material used in the electric kettle can only be regarded as a “healthy material” if it is inspected and certified by an authoritative organization and meets these two inspection standards. In addition, it can also be judged by the method of "seeing" and "smelling". Food grade stainless steel generally has a good gloss and does not smell strong metallic rust. Food grade PP materials generally look smooth, shiny, evenly textured, and smell no plastic odor.

Purchase details

Details 1. Base winding groove: The electric kettle with the winding groove on the base can adjust the length of the power cable according to actual needs, avoiding the messy situation of the kitchen or living room power cord.

Details 2, non-slip base: When the kettle is boiled, the kettle will cause serious consequences. Therefore, if the countertop or coffee table where the electric kettle is placed is relatively smooth, consumers should carefully check whether the base has anti-slip. Designed to avoid danger when the electric kettle is dumped.

Detail 3, the spout anti-scratch hand: Since the inside of the electric kettle needs to be cleaned frequently, if the edge of the stainless steel electric kettle is too sharp, it is easy to scratch the hand when cleaning, so consumers should carefully check the mouth when selecting. Whether to shave.

Details 4, opening method: There are two main ways to open the electric kettle. One-button opening and manual opening, consumers can choose a more convenient opening method according to personal habits.

Since electric kettles are used more frequently in daily life, when purchasing an electric kettle, it is also necessary to consider the details of the use to ensure the convenience of future use.

Introduction to the principle of electric kettle

The working principle of the electric kettle is: using the water vapor generated when the water boils to deform the bimetal of the steam sensing element, and using the principle of the lever to push the power switch, so that the electric kettle is automatically powered off after the water is boiled. The power failure is not self-resetting, so the kettle will not automatically reheat after the power is turned off.

The use of a PTC heating element instead of a heat pipe can effectively prevent the risk of fire due to dry burning. The dry burning temperature of the PTC heating element can be set at any temperature between 150 ° C and 250 ° C. When the temperature reaches the set temperature, the resistance of the PTC element increases rapidly, and the heating power drops sharply, keeping the temperature at the set. The temperature does not continue to rise. The PTC heating element's automatic temperature control is absolutely reliable. It relies on the resistance change in the PTC body to control the temperature, rather than relying on any contact control. Therefore, many high-grade electric kettles use PTC heating elements. However, because many electric kettle designers are not accustomed to using PTC heating elements, coupled with the relatively high price and relatively large size of PTC, its application is limited.

The PTC heating element has a great advantage for the insulation of the electric kettle. The insulation power of the electric kettle is relatively small, and the use of the PTC heating element does not increase the cost. The PTC heating element has an anti-dry function, and its dry burning power is about one tenth of the boiling water power. In the case of failure of the temperature control element, the PTC's own temperature is kept at a lower temperature without danger.

After reading the introduction of Xiaobian, now everyone knows how to choose a cost-effective electric kettle. Xiao Bian also introduces the principle of electric kettle to everyone, I hope that through the introduction of Xiaobian, you can have a deeper understanding of the electric kettle. It is also possible to better purchase products with higher cost performance.
