Description

Barbecue machine capable of heating double-sided infrared gas simultaneously

Technical Field

The invention relates to the field of barbecue machines, in particular to a barbecue machine capable of heating double-sided infrared gas simultaneously.

Background

Barbecued food is a very favorite food for people. Among the barbecue machines used in the prior art for grilling food, there are charcoal barbecue machines, electric barbecue machines, and infrared gas barbecue machines. However, these grilling machines share a common feature: when the food is heated, the heat source always faces one side of the food, and the food to be roasted needs to be repeatedly turned over when the food is roasted. Otherwise the food would be cooked on one side, raw on the other side or burnt on one side. On the other hand, the conventional barbecue mode always faces one surface of the food except the heat source, and the heat source is generally arranged below the food, so that the following problems are necessarily caused: firstly, the repeated rolling and roasting of food needs additional power consumption, if a set of rolling mechanism is not installed, the food needs to be continuously rolled by hands, the time and the energy are consumed, the labor consumption structure is complex, and the cost is high; secondly, in the process of repeatedly rolling and roasting the food, heat is conducted from the surface of the food to the interior of the food, so that when the heat on the surface of the food is transferred to a certain depth in the food, the surface of the heated food is transferred to a heat source, the surface of the heated food, which is opposite to the heat source, can release heat to the outside air without fail according to the heat transfer rule, and the speed of the heat conducted to the interior absorbed in the food can be slowed down. This makes the energy not utilized effectively, and the barbecue speed is slow and long; third, most of the existing various barbecue machines are arranged below food, and a layer of metal mesh is arranged between the food and the heat source, so that water and oil stains in the food are dripped down onto the heat source to generate smoke and oil smoke which can be attached to the food for smoking and baking, and the smoke flies to pollute the air in all the days, which is not environment-friendly, so that the baked food is easy to cause cancer after being eaten for a long time, and the food sanitation and the human health are seriously affected, which is proved by the modern medical science; fourthly, the barbecue machine using electric barbecue often causes a lot of street stall owners to be difficult because the power connection of the street stall is very inconvenient. How to solve the above problems of the prior art is a main subject of the present invention.

Disclosure of Invention
