Electric kettle capable of automatically shutting off steam channel

Abstract

The invention discloses an electric kettle capable of automatically shutting off steam channel, which comprises a kettle body and a switch button communicated with the inside of the kettle body through a steam channel component. The steam channel component comprises a steam pipe and a steam box; the two ends of the steam pipe are respectively communicated with the inside of the kettle body and the inside of the steam box; a steam sensing switch crosses in the steam box; a bimetallic strip is arranged at one side of the steam sensing switch, and a movable rod and a pair of electric contacts are arranged at the other side of the steam sensing switch; the movable rod is connected with the tail end of the switch button; the middle of the switch button is hinged on the steam box; a piston device is arranged joint between the steam pipe and the steam box; a connection rod is connected on the piston device; the tail end of the connection rod is hinged on the steam box, and the middle of the connection rod is sleeved on the switch button. The invention can power off and shut off the steam channel at the same time; and the steam sensing switch has high reset speed and is convenient to clean as the steam only forms a small amount of condensed water to overflow after condensed.

Description

technical field [0001] The invention relates to an electric heating device, in particular to an electric kettle which automatically shuts off a steam channel. Background technique [0002] Most of the current electric kettles have a heating automatic shutdown function. When the water or other liquids in the kettle are heated to boiling, the circuit of the electric kettle will be automatically turned off, making the electric kettle more convenient to use. At present, most products use thermosensitive elements such as bimetal strips or memory alloy elements to realize the above-mentioned automatic shutdown function. [0003] Most of the products realized by using the bimetal element will use the steam channel to guide the steam to the position of the bimetal, so that the bimetal can sense the temperature change in the pot in time, and ensure that the bimetal can be used immediately when the liquid in the pot boils. The sensor switch acts to turn off the power supply. However...

Problems solved by technology

However, the current problem with this product is that when the power of the electric kettle is automatically disconnected, the steam in the kettle will continue to enter the position of the bimetal sheet, and the bimetal sheet will continue to sense high temperature, and the induction switch resets slowly. It is inconvenient for the user to reheat the liquid in the pot. In addition, the steam condenses continuously on the steam channel, and the steam condensed water will further overflow out of the pot, giving the user the illusion of water leakage and causing trouble in cleaning.
