Embodiment 1

[0046] The cooking pot includes the bottom wall of the stainless steel pot body made of 430 stainless steel and the outer end surface of the bottom wall of the stainless steel pot body, which are successively sprayed with a ferromagnetic coating as the middle layer to form a magnetic conductive coating 2 and an outer layer of 304 stainless steel anti-corrosion coating. The antirust and wear-resistant layer 3 made of rust coating, the thickness of the magnetically conductive coating 2 is 200 μm, and the porosity is 12%, and the antirust and wear-resistant layer 3 is 30 μm. The double-coated stainless steel pot body can effectively reduce the The noise produced in the electromagnetic heating process can ensure that the surface of the pot has good rust resistance and wear resistance; this embodiment 1 cooking pot and 430 stainless steel soup pot without ferromagnetic coating and non-ferromagnetic coating The noise test results of the 430 stainless steel soup pot with double-layer ...

Abstract

The invention relates to a cooking pot and a manufacturing method thereof. The cooking pot comprises a stainless steel pot body, a magnetic conduction coating layer and an anti-rusting wear-proof layer, wherein the magnetic conduction coating layer is located on the outer side surface of the bottom wall of the stainless steel pot body, and the porosity of the magnetic conduction coating layer is 10%-15%; and the anti-rusting wear-proof layer adheres to the magnetic conduction coating layer. According to the cooking pot, the magnetic conduction coating layer with the porosity of 10%-15% is arranged on the bottom wall of the stainless steel pot body, and energy of partial noise can be absorbed and consumed through vibration of air in internal pores of the magnetic conduction coating layer, so that the noise in an electromagnetic heating process of the pot can be remarkably reduced; and furthermore, the anti-rusting wear-proof layer is arranged outside the magnetic conduction coating layer, so that the stainless steel pot body protected by the anti-rusting wear-proof layer does not rusted for a long time (1-2 years).

Description

technical field [0001] The invention relates to a cooking pot and a method for manufacturing the cooking pot, belonging to the field of kitchen cooking utensils. Background technique [0002] In the kitchen cooker in the prior art, the relatively large noise that the stainless steel pan will generate on the electromagnetic heating equipment causes troubles to people. Chinese patent 201520555609.5 discloses a cooking utensil, including a stainless steel pot body, a pot cover, and a sound-absorbing sound box arranged on the pot cover for releasing steam. The sound-absorbing sound box includes: a box seat, which is set close to the stainless steel pot body; On the box base and away from the stainless steel pot body; the sound-absorbing layer is set between the box base and the box cover and is made of flexible sound-absorbing materials. The sound-absorbing layer includes a partition wall, which together with the box base or / and the box cover encloses steam channel, this struct...
