Abstract

A barbecue grill having an airway comprises an inner wall (1), an outer wall (2) disposed above the inner wall (1), an airway (6) provided between the inner wall (1) and the outer wall (2), an air outlet (201) provided on the inner wall (1), and an air inlet (202) provided on the outer wall (2). The air outlet (201) and the air inlet (202) are in mutual communication with the airway (6), and a fan (4) is mounted at the air inlet (202). The barbecue grill having an airway utilizes the air inlet (202), the fan (4), and the airway (6) together to form a heated airflow containing energy by absorbing heat in the airway (6), thus facilitating complete combustion of charcoals with excellent efficiency. A heated air vortex is formed inside the airway (6) to effectively lower the temperature of the outer wall (2), thus achieving environmental friendliness, preventing heat loss, and also increasing the energy contained in the heated airflow by heat reuse and secondary air heating. In addition, convection of the heated airflow formed inside the inner wall (1) can uniformly heat food, and charcoals can be randomly distributed in a charcoal tray without using an additional chimney starter or container, thus preventing ash and smoke, and providing easy and convenient operation for users.

Description

Air duct type barbecue grill

Technical field

The invention relates to the technical field of barbecue grills, in particular to a duct type barbecue grill.

Background technique

At present, the traditional barbecue stove 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, and also generates a large amount of smoke and incidental harmful gases, such as carbon monoxide, which damages people's health to a certain extent and causes many undesirable factors to the environment.

In addition, the traditional structure can not control the size of the fire, the loss of heat is large and energy saving and environmental protection.

Later, there were some improved grills, the structure of which included an outer casing, a receiving bowl disposed in the casing at intervals on each side from the outer casing, a charcoal chamber in the receiving bowl, and a barbecue disposed above the charcoal chamber. A rack and an air supply device that produces a flow of air from the underside of the bowl to the charcoal chamber. This type of grill has the inadequacies: by adding a fan below, it directly blows carbon to play a role in combustion. Although there is some progress in this way, directly blowing the carbon into the natural wind directly blows in the low-energy wind outside, which will lead to the loss of some heat, the poor effect and the inconvenience of carbon removal.

Although oxygen can be supplied for charcoal combustion, the lower part of the device is cooled by cold air, which has a large loss of heat, and the charcoal is placed in a designated box, which is inconvenient to use, resulting in a low utilization rate of the grill and a low utilization rate of charcoal.
