Cooking utensil and electronic control switch and control method thereof

Abstract

The invention discloses a cooking utensil as well as an electronic control switch and a control method thereof. The electronic control switch comprises a stepping motor, an opening button, a closing button and a controller, wherein the stepping motor is arranged at the position of a hinge cover between a cover and a pot body of the cooking utensil and replaces the hinge cover, the opening button and the closing button are arranged on a control panel of the cooking utensil, and the controller is electrically connected with the stepping motor, the opening button and the closing button. The cooking utensil comprises the electronic control switch. The control method comprises the steps that when the controller receives a signal that the opening button is triggered, the stepping motor is controlled to rotate in the direction of opening the cover; when the controller receives a signal that the closing button is triggered, the controller controls the stepping motor to rotate in the directionof closing the cover. According to the cooking utensil as well as the electronic control switch and the control method thereof, the cover of the cooking utensil is electronically controlled to be opened and closed through the stepping motor, the stepping motor can accurately control the position of the cover, uncontrollable factors of a common mechanical cover opening and closing mechanism at present are reduced, and the risk that hands of a user are scalded is reduced.

Description

technical field [0001] The invention relates to electronic switch technology, in particular to a cooking utensil, an electronic control switch and a control method thereof. Background technique [0002] In daily life, users open and close the lid of cooking utensils such as rice cookers mechanically. The specific situation is to press the button to open the lid of the rice cooker, and then the lid of the rice cooker bounces off with an uncontrollable acceleration. After the lid of the rice cooker is opened to the maximum limit of the hinge lid, due to the inertia of the spring force, the lid of the rice cooker will bounce too hard; Press the lid of the rice cooker back with all your strength. This action of closing the lid of the rice cooker not only requires a lot of strength, but the hand travels a long distance, and the arm may be scalded by high-temperature steam when it passes above the rice cooker. Based on this hidden danger, there is an urgent need for an electronic...
