Embodiment Construction

[0036] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0037] The preparation method of the following double-layer soaking pot of the present invention: step 1, adopt the 403 stainless steel thin plate that thickness is 1mm, press molding in mold, make outer pot, the thickness is the 304 stainless steel thin plate of 1mm, in the same shape and ratio The outer pot mold is stamped and formed in a mold with a small size to make an inner pot, and the top edges of the inner pot and the outer pot have an extended platform-like structure;

[0038] Step 2, coating the inner surface of the outer pot and the outer surface of the inner pot with a copper powder adhesive layer made of pure copper powder containing a binder and an average particle size of about 60-80 μm. The copper po...

Abstract

The invention relates to a method for preparing a double-layer heat-uniformizing pot. The method comprises the steps that an inner pot and an outer pot are prepared; the outer side of the inner pot and/or the inner side of the outer pot are/is coated with a metal powder glue layer, and pressing, baking and sintering are performed; the inner pot is sleeved with the outer pot, the tops of the inner pot and the outer pot are sealed and fixedly connected, and a heat conduction cavity is formed between the inner pot and the outer pot; air in the heat conduction cavity is extracted from a vacuumizing hole formed in the outer pot, so that the heat conduction cavity is in a negative pressure state, a liquid phase change working medium is injected through the vacuumizing hole, and the vacuumizing hole is sealed. A porous metal layer is manufactured through the method. The porous copper layer can ensure that after the liquid phase change working medium is volatized into gas, the gas is passed to the condensed end at the top of the heat conduction cavity to be diffused, cooled liquid flows along the porous copper layer to the bottom of the heat conduction cavity and is heated again and evaporates, the heating process is repeated, and it is ensured that the temperature field at each part of the whole inner pot is basically kept consistent.

Description

technical field [0001] The invention relates to a double-layer soaking pot and a preparation method, belonging to the field of double-layer soaking pots. Background technique [0002] At present, the inner tank of electric rice cooker or pressure cooker that can be heated by electromagnetic is generally made of aluminum-stainless steel composite plate or aluminum-stainless steel double-bottomed steel plate, which is usually achieved by spraying non-stick coatings such as PTFE (Teflon) on the inner aluminum surface. The non-stick effect of its surface during cooking. However, these non-stick coatings have poor wear resistance and are relatively easy to fall off. After being absorbed by the human body, they may cause safety hazards to the health of consumers. How to achieve a pan body that does not need to spray PTFE to achieve uniform heating and prevent sticking is an art in the art Problems that technicians urgently need to solve. Contents of the invention [0003] The ...
