Description

Electric kettle and lid for the electric kettle The present invention relates to an electric kettle and a lid for an electric kettle. Generally, an electric kettle is a device that heats water contained within a main body using a heating means, such as a heater, via an electric power supply. Furthermore, electric kettles are configured so that the main body is detachably attached to a power-supplied base; they heat up while seated on the base and can be used by lifting the main body by the handle and separating it from the base. Electric kettles of this type are commonly referred to by various names, such as cordless electric kettles, cordless electric pots, and coffee pots. Electric kettles of this type are sometimes made of plastic material to facilitate the complex shape of the main body and the arrangement of internal components. However, when used for a long time, harmful components of plastic or microplastics can dissolve in high-temperature water, and there is a problem that the product is susceptible to scratches and other damage, which can lead to internal contamination. In addition, if the main body is formed from glass, it offers excellent hygiene and a superior appearance, but there is a risk of breakage due to impact, it is heavy and inconvenient to use, and there are issues with the difficulty of molding. Korean Utility Model Registration No. 20-0406420 discloses a cordless electric kettle in which the open upper surface of the main body is shielded by a lid, and the main body is made of stainless steel and capable of heating water contained inside. In such a structure, the main body is formed of stainless steel, which has the advantages of being highly hygienic and having excellent durability. However, in such a structure, a restraining structure between the lid and the main body is not provided, so there is a problem in that the lid may open arbitrarily due to pressure when the water boils, or the lid may open arbitrarily when the cup pot is tilted to pour water. In addition, Korean Patent Publication No. 10-2011-0134241 discloses an electric kettle having a structure in which a lid is provided on the open upper surface of the container of the main body, and the lid is rotatably mounted to the main body to prevent unauthorized opening. However, in this structure, the lid cannot be detached, which causes inconvenience in use and cleaning, and since there is no restraining structure between the container and the lid, the problem of the lid opening unintentionally still persists.
