Description

Portable prefab oven }

The present invention relates to a portable prefabricated fire pit, and more particularly, it consists of an outer furnace and an inner furnace that is fitted into the outer furnace, and provides a hot air guide space between the outer furnace and the inner furnace so that the heat stays in the hot air guide space for a certain period of time. By doing so, it is possible to increase the warming effect and improve the heating efficiency, and it has a structure in which fuel is injected from the outside, so that fuel can be easily injected in the process of cooking food.

Due to the recent five-day workweek, many office workers are trying to make use of their spare time. As part of these efforts, they study for personal development and exercise for health, but above all, they tend to spend leisure time with their family to offset the time they cannot spend together during the week. Therefore, to spend the weekend with family, camping culture in quiet and secluded places is gradually spreading. Unlike the old concept of simply eating and sleeping outdoors, the current camping culture temporarily forms a new residential space outdoors to rest comfortably.

Therefore, with the spread of this camping culture, various camping tools such as tents, cooking utensils, and outdoor bedding have been developed and sold. Among them, unlike the past in which the cooking utensils consist of only a burner and a koppel, various burner devices, tableware other than the koppel, and various cooking utensils have been developed. In particular, there is a tendency to cook various types of grilling, that is, roasting or smoking pork, beef, chicken, etc., rather than just having a simple meal outdoors.

An example of such an oven is shown in Registered Utility Model No. 394357. The registered utility model consists of a leg part and a cradle in a separate or foldable manner.
