Vacuum heat insulation basin

Abstract

The invention discloses a vacuum heat insulation basin which comprises a food containing basin comprising a food containing basin edge and a food containing basin body; and the vacuum heat insulation basin is characterized by also comprising a vacuum basin consisting of a vacuum outer shell and a vacuum inner shell. A vacuum chamber is formed between the vacuum outer shell and vacuum inner shell which are completely sealed; the food containing basin is put in the vacuum basin; a water containing cavity for containing water is formed between the food containing basin body and the vacuum inner shell; more than one group of clip holders with clips are evenly fixed on the side wall and at the bottom of the food containing basin body; and an annular heating body is clipped in each group of clips. More than one inner groove for discharging water or vapor is processed at the bottom of the food containing basin edge. The edge of the food containing basin is larger than that of the vacuum basin. The invention has the advantages that the vacuum heat insulation basin can heat and insulate heat for food within a certain period of time to enable people to eat delicious hot food, has no carbon black, is clean and sanitary, can be washed, moved and carried conveniently, has high utilization ratio, safety, reliability and simple manufacture and assembly, and is a novel field cooker.

Description

technical field [0001] The invention relates to cooking utensils, in particular to a vacuum heat-preserving pot which can keep food warm for a certain period of time. Background technique [0002] In spring, autumn or winter when the weather is colder, many employees in departments such as geology, petroleum, roads and railways carry out undetermined exploration operations in the field all year round or people who travel to the field cannot carry stoves and have no electricity when they have meals. Unable to eat delicious hot dishes and meals, they can only eat cold dry food (such as steamed buns, buns or bread) or instant noodles, and drink cold water to satisfy their hunger. This is the case all year round, and the proportion of stomach problems is very high. Some carry iron pans on their backs, and heat the iron pans with dead branches and leaves before eating to heat the food. Although this solves the problem of eating, a large amount of carbon black will be produced at ...

AI Technical Summary

Problems solved by technology

Some carry iron pans on their backs, and heat the iron pans with dead branches and leaves before eating to heat the food. Although this solves the problem of eating, a large amount of carbon black will be produced at the bottom of the iron pans, which is very dirty, not only cannot be cleaned at all, but also If you are not careful, you will pile up other items, increasing unnecessary workload
