In a first aspect of the invention, a cooking vessel is presented. According to an embodiment of the present invention, referring to fig. 1 to 5, a magnetostrictive member 200 is disposed on the cooking container 100, and the magnetostrictive member 200 is adapted to generate vibration in an alternating magnetic field.
According to the embodiment of the invention, the magnetostrictive member of the cooking container can generate stretching vibration in the alternating magnetic field, and the food is caused to generate ultrasonic vibration by the vibration, so that the water absorption and/or the taste of the food are promoted in the cooking process.
According to an embodiment of the present invention, a specific material forming the magnetostrictive member is not particularly limited as long as it is formed of a magnetostrictive material. In embodiments of the invention, the magnetostrictive material may be selected from: (1) metal and alloy magnetostrictive materials such as nickel (Ni) -based alloys (Ni, Ni-Co alloys, Ni-Co-Cr alloys), iron-based alloys (e.g., Fe-Ni alloys, Fe-Al alloys, Fe-Co-V alloys, etc.), and ferrite magnetostrictive materials such as Ni-Co and Ni-Co-Cu ferrite materials; (2) rare earth intermetallic magnetostrictive materials, e.g. with (Tb, Dy) Fe2The compound is an alloy of the matrix. Therefore, the material source is wide, and the magnetostrictive effect is good.
According to an embodiment of the present invention, the shape of the magnetostrictive member is not particularly limited, and may be selected by a person skilled in the art according to actual needs, and according to a specific embodiment of the present invention, the magnetostrictive member may be a magnetostrictive sheet, and the thickness of the magnetostrictive sheet may be 0.3 to 3 mm. Therefore, the magnetostrictive pieces can be conveniently arranged at different positions of the cooking container, and the thickness of the magnetostrictive pieces is in the range, so that the magnetostrictive rate of the magnetostrictive pieces is high, the magnetostrictive pieces can react in time through the change of a magnetic field, the deformation resistance is strong, the fatigue resistance is good, the stability is good, and the service life is long; when the thickness of the magnetostrictive sheet is less than 0.3mm, the magnetostrictive sheet is easy to deform or damage due to the fact that the magnetostrictive sheet is too thin and vibrates for a long time, and when the thickness of the magnetostrictive sheet is more than 3mm, the magnetostrictive sheet cannot make a corresponding telescopic reaction according to the change of a magnetic field in time and cannot reach the amplitude of preset vibration, so that noise reduction waves cannot be generated accurately in time.
According to an embodiment of the present invention, the magnetostrictive sheets may have a circular or square shape, whereby it may be further convenient to dispose the magnetostrictive sheets at different positions of the cooking container, thereby increasing the applicable range of the magnetostrictive sheets.
According to an embodiment of the present invention, the position where the magnetostrictive member is provided on the cooking container is not particularly limited.
According to an embodiment of the present invention, referring to fig. 2 to 3, the magnetostrictive members 200 may include two magnetostrictive members, and the two magnetostrictive members may be oppositely disposed on the sidewall of the cooking container. Thereby, the vibration intensity of the magnetostrictive member can be further improved, and the effect of the cooking container for promoting the water absorption and/or the taste of the food can be further improved.
According to an embodiment of the present invention, the magnetostrictive member 200 is disposed on the sidewall of the cooking container 100. Therefore, the magnetostrictive member can be prevented from influencing the heat transfer of the bottom of the cooking container.
In accordance with an embodiment of the present invention, and with reference to fig. 4-5, the magnetostrictive member 200 can also be disposed on the bottom wall of the cooking vessel. Thereby, the vibration intensity of the magnetostrictive member can be further improved, and the effect of the cooking container for promoting the water absorption and/or the taste of the food can be further improved. In addition, by arranging the magnetostrictive member on the bottom wall of the cooking container, the van der Waals force between the food and the cooking container can be weakened by utilizing the vibration of the magnetostrictive member, thereby achieving the effect of preventing the food from sticking to the pot.
