Energy-saving electric kettle

Abstract

The invention provides an energy-saving electric kettle. The energy-saving electric kettle comprises a kettle body and a kettle lid; an electric heating tube is installed at the lower portion of an inner cavity of the kettle body; conical surface transition is adopted for the bottom of the kettle body and the side wall of the kettle body, so that the lower portion of the kettle body is of a big-end-up structure; the electric heating tube is spiral, one connecting end is led from the lower end of the spiral electric heating tube, another connecting end is led from the upper end of the spiral electric heating tube, and the spiral electric heating tube is in matched connection with a socket arranged on the outer wall of the kettle body; the spiral electric heating tube is of an encircling structure formed by three layers of circular electric heating tube bodies. According to the energy-saving electric kettle, a traditional electric heating tube is changed into the three-layer spiral heating tube, so that the contact area of the heating tube and water is increased in the heating process, the energy consumption is reduced, the heat loss is prevented, and the heat efficiency is improved;conical surface transition is designed at the bottom of the kettle body, it is guranateed that the volume of water at the upper portion in the kettle body is larger than that of water at the lower portion in the kettle body, water at the bottom can rise easily, water at the upper portion can fall easily, and thus thermal circulation is promoted.

Description

technical field [0001] The invention belongs to the technical field of electric heating and relates to an electric kettle used for boiling water in daily life. Background technique [0002] At present, a commonly used electric kettle with a simple structure includes a pot body and a pot cover. A circle of electric heating tubes is installed at the lower part of the inner cavity of the kettle body. The inner cavity of the kettle body has a structure with a large lower area and a small upper area; When heating, the volume of cold water in the upper part of the kettle body is small, and the cold water in the upper part is not easy to drop, and the thermal cycle effect is not good, resulting in long heating time, large heat loss, and low heating efficiency. Contents of the invention [0003] In order to improve heating efficiency, make full use of heat, and reduce heating time, the present invention proposes an energy-saving electric kettle. [0004] For this reason, the tech...
