Thermal-insulation electric heating kettle

Abstract

The invention provides an insulating electric kettle. The kettle comprises a kettle body, heating elements, a water boiling heating circuit and an insulation heating circuit, wherein the heating elements are connected in the water boiling heating circuit in series; the insulation heating circuit comprises a kick type temperature controller and a PCB board for controlling power of the heating elements, which are connected in series; and the heating elements are simultaneously connected in the insulation heating circuit in series, so that heating elements simultaneously have functions of water boiling heating and insulating. The kettle reduces power when a heating tube works by utilizing the characteristic of the PCB board, or power reduction on the PCB board can be set into an adjustable mode, thereby realizing insulation of water in different capacities. The kick type temperature controller is an automatic reset temperature controller, and the operating temperature of the controller can be set according to requirement of different users so as to realize controllable water temperature. The insulating electric kettle has the advantages of simple and reasonable structure, high heat utilization rate, low cost, wide application range (such as households, hotels, tea houses and the like), and is applicable to mass production.

Description

technical field [0001] The invention relates to a thermal insulation electric kettle. Background technique [0002] Low-power thermal insulation kettle is a popular small household appliance. In the prior art, there are two main insulation methods: one is the double heating tube type, and the heating plate of the electric kettle is provided with two materials, the same structure or Similar but different power heating tubes, one is used for heating and boiling water, and the other is used for heat preservation. The heat pipe is combined with the PTC for heat preservation, the heat pipe is used for heating and boiling water, and the PTC is used for heat preservation. The PTC with this structure must be installed on the heating plate, which increases the volume of the kettle, cannot meet the customer's requirements for product appearance, and the production cost is high. [0003] Chinese Patent No. ZL200720050194.1 discloses a heat-insulating electric kettle, which includes a...

AI Technical Summary

Problems solved by technology

The electric kettle with this structure is heated by two heating elements, the heating chassis and the insulation sheet, which greatly increases the production cost, and the structure is complicated and the volume is large.
