Cooking appliance and its magnetostrictive actuator

Abstract

The invention discloses a cooking utensil, and a magnetostriction excitation device thereof. The cooking utensil comprises a pot body main body; the magnetostriction excitation device is arranged in corresponding to the pot body main body, and comprises a magnetic body, a magnetostriction member, an excitation coil, and a coil excitation source; the magnetic body is provided with an inner cavity;the inner cavity is provided with an opening facing the pot body main body; the magnetostriction member is arranged in the inner cavity, and is pressed against the pot body main body through the opening; the excitation coil is arranged in the inner cavity around the magnetostriction member; the coil excitation source is used for electric current excitation of the excitation coil, so that the excitation coil is capable of providing a magnetic field with variable amplitude; superposition of the magnetic field onto a single direction magnetic field formed in the inner cavity is capable of forminga total magnetic field; the magnetostriction member is capable of driving the pot body main body to vibrate under the effect of the total magnetic field, so that material extraction, emulsification,and water absorption in cooking process are promoted, material nutritional component deep extraction is achieved, and mouthfeel is improved.

Description

technical field [0001] The invention belongs to the technical field of living appliances, and in particular, the invention relates to a magnetostrictive excitation device for a cooking utensil and the cooking utensil. Background technique [0002] In a conventional rice cooker, after the user puts in the rice and water, press Start or make an appointment to start. The rice cooker starts to preheat and cook rice. During the cooking process, only the water itself absorbs the nutrition of rice grains or other ingredients, but because most of the water Time is in a state of slow motion, so the ability of water to absorb nutrients from ingredients is also poor, resulting in poor taste of cooked food. [0003] Therefore, existing electric cooker needs further improvement. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the first object of the present invention...
