Example Embodiment

[0034] According to a preferred embodiment of the present invention, the pot body 1 at least includes a straight portion with a maximum outer diameter and a downwardly reduced diameter portion located below the straight portion and connected to the straight portion. In this preferred embodiment, the magnetic permeable layer 3 is formed on the outer wall of the pot below the straight part. Further preferably, the magnetically permeable layer 3 makes a smooth transition between the straight portion and the downwardly reduced diameter portion, thereby displaying an aesthetically pleasing appearance. Still further preferably, on the outer wall of the pot of the downwardly reduced diameter portion connected to the straight cylinder portion, the thickness of the magnetic permeable layer 3 gradually decreases from bottom to top.

[0035] For the inner pot of the above-mentioned preferred embodiment, in the pot body 1, an upwardly reduced diameter part can be arranged on the upper par...

Example Embodiment

[0056] Example 1

[0057] The 3003 aluminum plate is stretched and stamped to obtain a pot body with a straight part at the top and a bottom part at the bottom. The diameter of the straight part is 220 mm, and the diameter of the bottom of the pot is 180 mm. The height of the straight part and the bottom part is The ratio is 3:1, the outer diameter of the bottom part of the pot gradually decreases from top to bottom, the side wall of the bottom part of the pot is arc-shaped, and the included angle between the tangent line of the arc and the vertical direction is 0-45°. Afterwards, the outer surface of the pot body is degreased and degreased. Then the pot body is fixed on the rotation tooling, the manipulator is set, the spraying range is from the center of the bottom of the inner pot to the maximum radius of the side wall of the pot body, and the cold spraying is carried out under the conditions of the parameters shown in Table 2 below while the inner pot is rotating. Thus, t...

[0058] Example 2

[0059] The 3003 aluminum plate is stretched and stamped to obtain a pot body with a straight part at the top and a bottom part at the bottom. The diameter of the straight part is 217 mm, and the diameter of the bottom of the pot is 160 mm. The height of the straight part and the bottom part is The ratio is 3.5:1, the outer diameter of the bottom part of the pot gradually decreases from top to bottom, the side wall of the bottom part of the pot is arc-shaped, and the included angle between the tangent line of the arc and the vertical direction is 0-45°. Afterwards, the outer surface of the pot body is degreased and degreased. Then the pot body is fixed on the rotation tooling, the manipulator is set, the spraying range is from the center of the bottom of the inner pot to the maximum radius of the side wall of the pot body, and the cold spraying is carried out under the conditions of the parameters shown in Table 2 below while the inner pot is rotating.

Abstract

The invention relates to the field of household appliances, and discloses an inner pot suitable for electromagnetic heating, a manufacturing method of the inner pot, and a cooking utensil. The inner pot comprises a pot body, the pot body is in the shape with unequal outer diameters, and a magnetic conductive layer is formed on the outer surfaces of the position with the maximal outer diameter andpart below the position with the maximal outer diameter of the pot body. For the inner pot provided by the invention, the bonding strength between the metal magnetic conductive layer and the pot bodyis high, meanwhile, the boundary between the magnetic conductive layer and the upper pot body is clear, and the magnetic conductive layer and the pot body can form smooth transition, so that the appearance is attractive.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to an inner pot suitable for electromagnetic heating, a manufacturing method thereof, and a cooking utensil. Background technique [0002] Electromagnetic heating relies on the magnetic field lines to penetrate the pot body for heating, without passing through the heating medium, and the heat energy loss is small. Therefore, using electromagnetic heating to heat pots has become a conventional heating method in kitchen cooking utensils. However, the inner pots of existing electromagnetic heating appliances (such as electric rice cookers, electric pressure cookers, etc.) are generally processed by stretching composite plate materials, and such pots are expensive. [0003] In order to reduce the manufacturing cost of the inner pot suitable for electromagnetic heating, in the prior art, attempts have been made to prepare a layer of magnetically conductive metal layer on the bottom of...
