Description

High-efficiency high-energy-saving heating structure for pot

Technical Field

The utility model relates to the technical field of electric heating stewing tools, in particular to a high-efficiency high-energy-saving pot heating structure.

Background

At present, a large amount of food materials are stewed in restaurants or restaurants by using an iron pot or a stainless steel pot with an enlarged capacity on a gas stove or a natural gas stove, and when the stewing pot is stewed in summer, the temperature of a kitchen is overhigh due to the use of the gas stove or the natural gas stove, so that the comfort level of the kitchen is influenced. On the other hand, the existing electric food warmer using electricity has the problems of low heat efficiency and large heat energy waste, which causes electricity and time waste; the key factor for causing the problems is that the traditional stewing pot is of a single-layer structure and is heated at the bottom, the bottom of the pot is heated to raise the temperature and transfer heat, food is cooked, and the traditional energy sources such as coal, wood fire, gas, an induction cooker, an electric heating stove and the like are heated, raised in temperature and stewed from the bottom of the pot. It is also a common, customary, and long-established thinking structural design in the industry. However, the same problems exist in the heating and stewing from the bottom: firstly, the heating area is small, the heat exchange area is small, and the heat efficiency is slow, and the stewing time is long; secondly, the heat exchange is only on one plane at the bottom, which causes a heat generating source, such as a flame, most of the area is exposed to the outside, the heat loss is large, and the heat energy conversion efficiency is low; thirdly, the bottom of the pot is heated in a concentrated manner, the whole pot is heated unevenly, and the heat of a local concentrated hot spot is too high, so that the food materials falling to the bottom are easy to paste, the heat conduction is slow, and particularly the food materials which are easy to paste like soybean milk are easy to paste. When the stewing amount is too large, the heating is concentrated, the conversion efficiency is low, the heat energy is wasted greatly, the stewing time is long, and the energy is wasted.

SUMMERY OF THE UTILITY MODEL

Aiming at the problems and defects in various aspects in the prior art, the inventor provides an advanced heating structure with high heat transfer, energy conservation and efficiency through experience, research and creation of decades, overcomes the defects and defects in the prior art, and achieves the effects of comprehensive conversion of heat efficiency, no energy waste and high-efficiency stewing.
