Embodiment Construction

[0033] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some embodiments of the present invention, not all of them. Based on the implementation manners in the present invention, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention. In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as there is no conflict with each other.

[0034] It should be noted that in the automatic start control circuit of the electric kettle, the prior art generally uses a sensor for start control. For example, when the user puts the kettle on the base, the sensor detects a pressure signal, the heating circuit is turned on, and the kettle Start boili...

Abstract

The invention relates to the technical field of electric kettle and in particular provides a control circuit of an electric kettle and the electric kettle. The control circuit includes: a signal detection unit, with an input end thereof being connected to an input power supply through a second switch and used for detecting and outputting a starting signal of the electric kettle; a heating controlunit with an input end thereof being connected to an output end of the signal detection unit and an output end thereof being connected to a heating device of the electric kettle, wherein the heating control unit controls the heating device to work according to the starting signal output by the signal detection unit; and a feedback control unit with a first input end thereof being connected to thesignal detection unit, a second input end thereof being connected to the heating device and an output end thereof connected to the second switch, wherein the feedback control unit generates a feedbacksignal according to the starting signal detected by the signal detection unit and a working state signal of the heating device, and cuts off the second switch according to the feedback signal. The control circuit of the invention avoids the problem of automatically starting water boiling of the kettle repeatedly, thereby achieving higher security.

Description

technical field [0001] The invention relates to the technical field of electric kettles, in particular to a control circuit of the electric kettle and the electric kettle. Background technique [0002] Electric kettle is a kind of commonly used household appliances, which has the advantages of convenience, speed, energy saving, beauty, etc., and meets the requirements of modern fast-paced life. Existing electric kettles generally include a kettle and a base. When boiling water, the kettle filled with water needs to be placed on the base, and then the switch set on the handle or body of the kettle is pressed to start boiling water. Open to break the circuit. The disadvantage of this push-button switch is that it is easily damaged and difficult to repair after frequent use. Once the push-button switch is damaged, the kettle cannot be used normally. At the same time, the push-button switch needs to be manually operated by the user. Difference. [0003] In order to solve the ...
