Efficient heat-conversion cooking pot with bottom surface being covered by stainless steel and manufacture method of cooking pot

Abstract

The invention relates to kitchen utensils and discloses an efficient heat-conversion cooking pot with the bottom surface being covered by stainless steel and a manufacture method of the cooking pot. The efficient heat-conversion cooking pot comprises a single-layer pot body, an aluminum plate covering the bottom of the pot and a covering stainless steel pot bottom, wherein the aluminum plate is placed at the bottom of the single-layer pot body; the bottom of the single-layer pot body and the aluminum plate are covered through the covering stainless steel pot bottom; a plurality of rings of grooves are arranged at the covering stainless steel pot bottom, the cross sections of the grooves are sine-wave-shaped; and a mock black coating subjected to sand blasting is arranged on the external surface of the covering stainless steel pot bottom. The manufacture method comprises the following steps of: manufacturing the plurality of rings of grooves with the sine-wave-shaped cross sections on the covering stainless steel pot bottom; integrally connecting the single-layer pot body, the aluminum plate and the covering stainless steel pot bottom by welding at high frequency; and softening the aluminum plate at a high temperature, and pressurizing the aluminum plate to be formed under the pressurization of the plurality of rings of grooves, thus forming the bottom-covering pot with the plurality of grooves with the sine-wave-shaped cross sections. The efficient heat-conversion cooking pot has high heat conversion efficiency and large surface area for heating, is uniform in heating and convenient to clean, and can absorb heat.

Description

technical field [0001] The invention relates to a kitchen utensil. In particular, it relates to a high-efficiency heat energy conversion cooking stainless steel bottomed pot. The invention also relates to a manufacturing method of a stainless steel bottom-coated cooking pot with high-efficiency heat energy conversion. Background technique [0002] In the existing pots, one is that the bottom is flat, and the heating surface is the bottom area, and the heating surface is limited. The second is that although there are some uniform grooves on the bottom of some pots, the depth is very shallow, and the increase of the surface area of ​​the bottom is far from enough. The cross-section of the grooves is mostly rectangular or triangular, and the heating is not uniform enough, which affects the conversion of heat energy. . Rectangular or triangular grooves are also prone to dead corners where dust can be hidden, which is difficult to clean. Moreover, the bottom of this pot is the...

[0002] In the existing pots, one is that the bottom is flat, and the heating surface is the bottom area, and the heating surface is limited

The second is that although there are some uniform grooves on the bottom of some pots, the depth is very shallow, and the increase of the surface area of ​​the bottom is far from enough. The cross-section of the grooves is mostly rectangular or triangular, and the heating is not uniform enough, which affects the conversion of heat energy.

Rectangular or triangular grooves are also prone to dead corners where dust can be hidden, which is difficult to clean. Moreover, the bottom of this pot is the true color of metal, and with the polishing process, it has a strong reflective effect, especially for use on infrared and heat radiation stoves At this time, the heat that can be absorbed is very little, a large amount of heat energy is reflected, and the energy loss is very large, which affects the conversion of heat energy
