Electric kettle and working method thereof

Abstract

The invention discloses an electric kettle. The electric kettle comprises a body which is provided with an upper coupler, a base component which is provided with a lower coupler, a control circuit which is arranged in the base component, and a user operation device, wherein the body and the base component are connected through the upper coupler and the lower coupler, and a heating circuit is formed between the body and the base component; the body comprises a container which forms a liquid accommodation cavity; the bottom of the container is provided with an electric heating component; a bimetallic strip temperature controller is arranged on the lower surface of a bottom wall of the container; the bimetallic strip temperature controller and the electric heating component are connected in series in the heating circuit; a current detection unit is arranged in the control circuit; a relay which is communicated with the control circuit is also arranged in the heating circuit; and the control circuit controls the connection or disconnection of the relay according to detected on/off electric signals of the heating circuit.

Description

technical field [0001] The invention relates to a small household appliance, in particular to a household electric kettle and a working method thereof. Background technique [0002] Consumers are very familiar with electric kettles, and technicians in the field of electric kettle industry are also very familiar with the structure of electric kettles. Most ordinary electric kettles control the power off of electric kettles through the steam generated after boiling water in electric kettles. The use of steam to control the power off of the electric kettle is defective; the first defect is that the steam generated by the electric kettle equipped with a steam conduit enters the steam conduit after the boiling water is boiled, and the steam in the steam pipe will form condensed water after cooling, and this Condensed water will flow to the electric control part at the bottom. Such a structure is actually a safety hazard. The second defect is that at higher altitudes, even if the ...

[0002] Consumers are very familiar with electric kettles, and technicians in the field of electric kettle industry are also very familiar with the structure of electric kettles. Most ordinary electric kettles control the power off of electric kettles through the steam generated after boiling water in electric kettles. The use of steam to control the power off of the electric kettle is defective; the first defect is that the steam generated by the electric kettle equipped with a steam conduit enters the steam conduit after the boiling water is boiled, and the steam in the steam pipe will form condensed water after cooling, and the Condensed water will flow to the electric control part at the bottom. Such a structure is actually a safety hazard. The second defect is that at a higher altitude, even if the water boils, it will not reach the set boiling temperature because there is no sufficient heat generated. If there is a large amount of steam, the heating power supply continues to heat, and the power supply cannot be cut off immediately, which has hidden dangers of safety accidents; the third defect is that the steam conduit is placed in the kettle, or the steam switch is placed on the handle of the electric kettle. These structures are not conducive to cleaning, and they cannot be placed. It is washed directly in water and this structure affects the appearance

The above-mentioned technical solutions, or there are technical defects that cannot be waterproofed, inconvenient to clean, or there is a situation of repeated heating, which needs to be improved
