Description

Technical Field

[0001] The utility model provides a side-fire modular metal fire grate barbecue oven, belonging to the technical field of barbecue ovens. Background Art

[0002] A barbecue grill is a cooking device designed specifically for grilling food. It is widely used in outdoor gatherings, family backyard barbecues, restaurants, street food stalls and other occasions. It can generate high temperatures through different heat sources such as charcoal, gas, electricity, solar energy, etc., thereby grilling a variety of delicacies such as lamb kebabs, barbecue, grilled vegetables, grilled fish, etc.

[0003] There are mainly two types of gas barbecue grills commonly used in the market. One is a barbecue grill with a ceramic plate infrared fire grate side heating device, and the other is a barbecue grill with a metal tube matrix fire grate bottom fire heating device.

[0004] The main structure of the ceramic plate infrared side heating barbecue oven is: 4 ceramic plate infrared fire grills are symmetrically arranged on the same horizontal plane, with the heating surfaces of the fire grills facing each other vertically, two DC 12V heat-averaging small fans installed on the inner sides of the left and right sides of the oven respectively, two gas valves installed on both sides of the front of the oven to control the fire grills on both sides of the heating surfaces, and an oil and water tank set under the fire grill. At present, the barbecue ovens with ceramic plate infrared fire grille side heating devices have the following disadvantages when in use: 1. The ceramic plate infrared fire grille is easy to get water and oil under high temperature and thus break; 2. The ceramic plate infrared The outer net of the wire grate is very easy to burn out and usually has a lifespan of only three to four months; third, it is difficult to balance the temperature of the grill mouth. The main reason is that one gas valve is divided into two gas nozzles to supply gas to a pair of grates. The amount of gas obtained by the two grates is difficult to be uniform, so the heat generated by the grates is different, resulting in uneven temperature at the furnace mouth and uneven fire; fourth, the existing gas grills with ceramic plate infrared grates, no matter how long the oven specifications are, the grates are divided into four groups controlled, and the length of the oven is different. When a gas valve is opened, half of the oven is working. When there are not many grilled items, it is too wasteful of energy and not energy-saving.

[0005] The main structure of the metal tube matrix type fire grate bottom fire barbecue oven is: a number of groups of metal tube matrix fire grates are set on the same horizontal plane just below the grilling port, according to the length of the barbecue oven, the heating surface of the fire grate is just below the grilled food, two DC 12V heat-averaging small fans are installed on the inside of the right side of the oven, and a number of gas valves corresponding to the matrix fire grate are installed on the front of the oven. An oil and water tank is set below the fire grate. At present, the metal tube matrix type fire grate bottom fire barbecue oven has the following disadvantages when in use: 1. The matrix fire grate combustion cover plate directly below the grilled food is easily corroded by seasoning, oil, water, and salt, and its service life is usually Six to eight months; Second, when oil drips on the combustion cover of the matrix fire grate that is at high temperature, when there is seasoning carbide on the surface of the combustion cover, black smoke and black particles are generated before the ignition point of the oil and carbide is reached, which are directly attached to the surface of the grilled food above, not only affecting the appearance of the grilled food, but also affecting personal health when eating such grilled food; Third, when oil drips on the combustion cover of the matrix fire grate that is at high temperature, when there is seasoning carbide on the surface of the combustion cover, when the ignition point of the oil and carbide is reached, a small flame is directly started, and when the flaming carbide falls into the oil collecting tank below, it is very easy to cause the oil in the oil collecting tank to burn, causing a big fire, posing a fire hazard.
