Outer container of meal stove

Abstract

An outer container of a meal stove comprises an outer container body and a laying bottom. The laying bottom is located in the center of the bottom of the outer container body, and the bottom of the outer container body is provided with a plurality of protrusions which are arranged around the laying bottom and evenly arranged around the center. The outer container of the meal stove is characterized that annular protrusions are arranged between the laying bottom and the protrusions which are arranged on the bottom of the outer container body. The outer container of the meal stove has the advantages of being capable of reducing the heat expansion and cold contraction difference of the laying bottom structure in all the directions in the using process and reducing heat deformation.

Description

technical field [0001] The invention relates to a cooking stove outer vessel, more precisely, it relates to a technical structure of a dining stove outer vessel. Background technique [0002] The dining stove mainly includes an inner tank and an outer tank. The outer tank of the dining furnace is filled with water, the inner tank is filled with food, and the inner tank is placed in the outer tank to contact with water. Heating the bottom of the outer tank raises the temperature of the water in the outer tank, indirectly heating and keeping the food in the inner tank warm. At present, more and more electromagnetic cookers are used for heating in the market. If the material of the outer tank is non-magnetic stainless steel, it is necessary to apply a bottom of magnetic material on the bottom of the outer tank. Most of the cooker heads of electromagnetic cookers are round. The shape of the bottom of the outer pot is also mostly round to match the round stove head, but when the...

Problems solved by technology

At present, more and more electromagnetic cookers are used for heating in the market. If the material of the outer tank is non-magnetic stainless steel, it is necessary to apply a bottom of magnetic material on the bottom of the outer tank. The shape of the bottom of the outer pot is also mostly round to match the round stove, but when the dining stove and the outer pot are rectangular, it is unsightly to put a round bottom on the bottom of the outer pot, and it is very unsightly to put it on a flat table. Stablize

Although the patent No. CN201520012457.4 solves the above problems, if figure 1 In the manufacturing process, due to the high temperature generated at the bottom 2` during the bottom coating process, it is transmitted to the raised part 3`, and the temperature of the ring area 1` on the edge of the bottom 2` is also very high, and the shape of the ring area 1` is irregular and Complicated, resulting in inconsistent thermal expansion and contraction in all directions. If the cooling rate is too fast, it will easily deform the bottom of the outer tank, affecting production efficiency and product quality
