Background

The traditional barbecue oven is a barbecue device, and is a stove for barbecue of materials such as mutton shashlik, vegetables and barbecue. The barbecue grill is carried to the field by the trolley on weekends, chats and drinks smoothly while enjoying the fun of barbecue, on one hand, the barbecue grill can fly to relieve the mental state to relieve the pungency of working at ordinary times, on the other hand, a new bright spot is newly added for urban life, and the barbecue grill is a novel leisure catering mode capable of improving the life quality of people. Barbecue ovens can be divided into charcoal, gas, electric, microwave and solar ovens, with gas and electric ovens being popular for their smoke and smoke free, non-polluting qualities. However, the electric oven is difficult to adapt to field use due to the limitation of power supply, and the electric oven is also a gas oven which is most widely applied. The basic principle of the gas barbecue oven is that gas is ignited into flame through an oven core to generate heat, and then the combustion heat is used for barbecue and decoction of materials. Along with the improvement of living standard and the continuous update of consumption concept, the shape, the structure and the function of the barbecue oven are also continuously updated along with wider adaptability, especially in European and American markets, even the barbecue oven is integrated into landscape elements, so that the barbecue oven has a brand-new conceptual structure integrating barbecue, decoction, heating and landscape, and simultaneously, various structural forms including wall hanging, fireplaces, table tables and the like are evolved due to the need of adapting to different environments and occasions. The stove core which is used as a core component is a traditional functional stove for barbecue and decoction or a modern concept stove integrating multiple functions, and the reasonable design of the structural form, the power and the combustion-supporting air-fuel ratio is very important.

Disclosure of Invention

In order to solve the technical problems of different structural forms and different power gas furnaces adapting to the furnace core, the utility model provides an H-shaped tubular gas furnace core which is one of a series of furnace cores.

The utility model adopts the technical proposal that: an H-shaped tubular gas furnace core comprises a furnace core body, combustion holes, a gas connecting pipe and a combustion-supporting air port, wherein the furnace core body is a plane H-shaped structure which is made of metal pipes and comprises a horizontal pipe connected between two vertical pipes, two ends of each vertical pipe are respectively a closed end and a fixed end, the closed end is positioned at the end head of the lower end of each vertical pipe and is directly pressed into a closed flat structure, the fixed end is positioned at the upper end of each vertical pipe and is directly pressed into a flat surface and forms a corner with an H-shaped upper plane, the corner surface is provided with a fixed hole, the combustion holes are fine round holes and are composed of a plurality of pipes which are uniformly distributed along an H-shaped line on the furnace core body, the gas connecting pipe is a tubular structure comprising a connecting end and a sleeve connecting end, the connecting end is communicated and connected with the middle below the horizontal pipe, the sleeve connecting end is a port for sleeving a gas, the combustion-supporting tuyere is a through opening connected with an insect-proof net and consists of two parts distributed on two sides of the sleeving end.

The utility model has the advantages that: the utility model relates to one of the furnace cores of an outdoor heating gas furnace series. Firstly, the series of gas stove cores have the characteristics of small volume, high power, soft and beautiful flame color and the like; secondly, the furnace cores of various specifications achieve the optimal proportion of a gas nozzle and a combustion-supporting air port through repeated tests in a laboratory; the furnace core of the series is designed strictly according to the principle of a Venturi tube, and outside air is adsorbed by negative pressure in a combustion-supporting air port to flow into a furnace core cavity to be fully mixed with gas, so that the combustion-supporting effect of soft and beautiful flame is achieved, and the gas is prevented from leaking from the combustion-supporting air port.

The present invention will be further explained with reference to the accompanying drawings:

fig. 1 is a schematic perspective view of the present invention.

In the figure, 1, a furnace core body, 2, combustion holes, 3, a gas connecting pipe, 4, a combustion-supporting air port, 5, a closed end, 6, a fixed end, 7, a connecting end, 8, a sleeve joint end, 9, a gas nozzle, 10 and an insect-proof net.

Detailed Description

In the embodiment of fig. 1, an H-shaped tubular gas furnace core is composed of a furnace core body 1, combustion holes 2, gas connecting pipes 3 and combustion-supporting air ports 4, wherein the furnace core body 1 is a planar H-shaped structure made of metal pipes and connected between two vertical pipes, two ends of each vertical pipe are respectively a closed end 5 and a fixed end 6, the closed end 5 is positioned at the end head of the lower end of each vertical pipe and directly pressed into a closed flat structure, the fixed end 6 is positioned at the upper end of each vertical pipe and directly pressed into a flat surface and forms a corner with an H-shaped upper plane, the corner surface is provided with a fixed hole, the combustion holes 2 are fine round holes and are composed of a plurality of pipes uniformly distributed along an H-shaped line on the furnace core body 1, the gas connecting pipes 3 are tubular structures including a connecting end 7 and a sleeving end 8, the connecting end 7 is communicated and connected to the middle of the lower surface of the horizontal pipe, the, an isolation mounting plate is arranged on the port of the sleeve connection end 8, a gas nozzle 9 is connected onto the isolation mounting plate, and the combustion-supporting air port 4 is a through port connected with an insect-proof net 10 and consists of two parts distributed on two sides of the sleeve connection end 8.

Example 1: the series of gas furnace cores comprise various specifications, and the optimal proportion of the gas nozzle 9 and the combustion-supporting air port 4 is achieved after the furnace cores with various specifications are repeatedly tested in a laboratory; the flue gas emission of the furnace cores with various specifications is lower than the CSA certification index of 2000ppm through the flue gas test of a laboratory, and the standard of entering the European and American markets is achieved; this series of gas furnace core still because design according to the venturi principle strictly, can produce the low pressure near according to "fluid that flows at a high speed", thereby produce the venturi effect of adsorption, when the gas passes through the gas nozzle 9 that the sectional area diminishes, produce higher velocity of flow under the effect of pressure, just form the negative pressure in the combustion-supporting wind gap 4, the negative pressure region plays the adsorption to the air outside combustion-supporting wind gap 4, the air flows into the furnace core chamber from combustion-supporting wind gap 4 and fully mixes with the gas, both reached the combustion-supporting effect of soft beautiful flame, prevent again that the gas from leaking from combustion-supporting wind gap 4.

Example 2: the hook-type H-shaped tubular gas furnace core is adapted to an outdoor heating barbecue oven with a special-shaped switch plate at the simple furnace bottom at one end of the oven body. At first with the anchor clamps of box end 5 centre gripping to the furnace body and with stiff end 6 back in being connected to the furnace body, be connected to box end 5 with the air supply pipeline through the gas switch again, connect and adjust the locating firer at last, the outdoor gas heating oven that a simple and easy stove bottom of dysmorphism can use.
