Electric kettle

Abstract

The invention provides an electric kettle. The electric kettle comprises a liner, a heat-conduction plate and a heating device, wherein the liner comprises a bottom plate and a lateral enclosing plate; the bottom plate is connected with the lateral enclosing plate to form an accommodating cavity for containing liquid; a plurality of projections are arranged on the bottom plate and are positioned in the accommodating cavity; the heat-conduction plate is arranged below the bottom plate; and the heating device is arranged on the heat-conduction plate. The projections are arranged on the bottom plate of the electric kettle and are positioned in the accommodating cavity, on the one hand, the structural strength of the bottom plate is improved by the projections, the reliability of the product is improved, on the other hand, heat transfer of liquid and convection of the liquid are affected by the projections, generation and aggregation of air bubbles are accelerated, therefore, a plurality of small air bubbles are aggregated into a large air bubble, the problem that a large number of small single air bubbles are changed into a large air bubble which is exploded to cause large noises is avoided, the number of the exploded air bubbles is reduced, sound produced by exploding of the air bubbles is suppressed, noises produced when liquid is heated in the electric kettle are reduced, and the use comfort of the product is improved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an electric kettle. Background technique [0002] At present, the existing electric kettles generally have the problem that a large number of air bubbles are generated at the bottom of the inner tank cavity during the boiling process, and the noise is generated as the air bubbles rise and become larger and then disappear. The speed of production is getting faster and faster, and the number is also increasing, resulting in greater noise and reducing the comfort of the product. Contents of the invention [0003] In order to solve at least one of the above technical problems, the object of the present invention is to provide an electric kettle with good noise reduction effect and low noise. [0004] In view of this, an embodiment of the present invention provides an electric kettle, comprising: an inner tank, including a bottom plate and a side wall, the bottom plate is connec...
