Air duct type barbecue grill

Abstract

The invention particularly relates to an air duct type barbecue grill, comprising an inner lining. The inner lining is provided with an outer lining. An air duct is disposed between the inner lining and the outer lining. The inner lining is provided with an air outlet. The outer lining is provided with an air inlet. The air outlet and the air inlet are communicated separately with the air duct. The air inlet is provided with a fan. The air duct type barbecue grill has the advantages that the combination of the air inlet, fan and air duct is used to absorb heat in the air duct, forming energized hot air that helps carbon to fully burn efficiently with high energy; rotary hot air formed in the air duct is effective in lowering the temperature of the outer lining, thus giving energy saving and environment protection and blocking heat loss, and also reuses the heat and secondarily heats the air, thus increasing the energy of the hot air; in addition, the hot air convection formed in the inner lining also evenly heats food; charcoal is distributed freely below a charcoal tray, the need for specially storing the charcoal in a flame guide tray or box is avoided, simplicity, no ash and no smoke occur, and a user's operation is facilitated.

Description

technical field [0001] The invention relates to the technical field of a barbecue oven, in particular to an air duct type barbecue oven. Background technique [0002] At present, the traditional barbecue grill adopts the traditional natural air convection method to provide air or oxygen combustion for the combustion of charcoal. However, this method has insufficient oxygen supply, difficulty in ignition, and insufficient combustion. It also produces a large amount of smoke and accompanying harmful gases, such as carbon monoxide, which damages people's health to a certain extent and also produces many adverse factors to the environment. [0003] In addition, the traditional structural method can not control the size of the fire, the loss of heat is large, and it is not energy-saving and environmentally friendly. [0004] There are also some improved grills later, the structure of which includes a shell, a receiving bowl arranged in the shell at intervals from the shell on ea...

AI Technical Summary

Problems solved by technology

This kind of barbecue grill has disadvantages: through adding a fan at the bottom, blowing charcoal directly to play a combustion-supporting role

Although this method has made some progress, but directly blowing the charcoal with natural wind and directly blowing in the low-energy wind from the outside will lead to the loss of part of the heat, poor effect and inconvenient charcoal release.

[0005] Although it can provide oxygen for charcoal to burn, the lower part of the device enters the cold air, which causes a large loss of heat, and the charcoal is placed in a designated box, which is inconvenient to use, resulting in low space utilization and charcoal utilization of the barbecue grill.
