Description

I type tubular gas furnace core of couple type

Technical Field

The utility model relates to a gas stove core, in particular to a I-shaped tubular gas stove core of a hook type, which belongs to the technical field of gas stoves.

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 furnace adaptive furnace cores, the utility model provides a hook type I-shaped tubular gas furnace core which is one of a series of furnace cores.

The utility model adopts the technical proposal that: the utility model provides a I tubular gas furnace core of couple type, by the furnace core body, burner port and combustion-supporting wind gap constitute, the furnace core body is for making the couple type structure including long limit and minor face and divide into the blind end and cup joint the end by metal tubular product, the blind end is at the end of minor face and for directly suppressing by tubular product closed platykurtic structure, cup joint the end on long limit and for the port of suit gas source pipeline, the structure of isolation mounting plane is suppressed by tubular product to the cup joint end, the end of cup joint end still is connected with the gas nozzle, the burner port is tiny round hole structure and by following a plurality of constitutions of couple type curve evenly distributed on the furnace core body, combustion-supporting wind gap is for being connected with the through mouth of insect-proof net and by distributing and serving two constitutions at the cup joint.

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.

Drawings

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 combustion-supporting air port, 4, a closed end, 5, a sleeve joint end, 6, a gas nozzle, 7 and an insect-proof net.

Detailed Description

In the embodiment of fig. 1, a hook type i-shaped tubular gas furnace core is composed of a furnace core body 1, combustion holes 2 and combustion-supporting air ports 3, wherein the furnace core body 1 is a hook type structure made of metal pipes and including long sides and short sides and is divided into a closed end 4 and a sleeving end 5, the end of the closed end 4 at the short side is directly pressed into a closed flat structure by the pipes, the end of the sleeving end 5 at the long side is a port for sleeving a gas source pipeline, the sleeving end is a structure pressed by the pipes into an isolation mounting plane, the combustion holes 2 are fine round hole structures and are composed of a plurality of pipes which are uniformly distributed on the furnace core body 1 along a hook type curve, and the combustion-supporting air ports 3 are through ports connected with insect-proof nets 7 and are composed of two pipes which are distributed on the upper side and the lower side of the sleeving end 5.

Example 1: the series of gas furnace cores comprise various specifications, and the optimal proportion of a gas nozzle and a combustion-supporting air port 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 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, the negative pressure region plays adsorption to the air outside the combustion-supporting wind gap, the air flows into the furnace core chamber from the combustion-supporting wind gap and fully mixes with the gas, both reached the combustion-supporting effect of soft beautiful flame, prevent again that the gas from leaking from the combustion-supporting wind gap.

Example 2: the hook type I-shaped tubular gas furnace core is adapted to an outdoor heating barbecue oven with a special-shaped simple furnace bottom. After the gas connecting pipe is clamped to the fixture of the furnace body, the gas source pipeline is connected to the sleeve joint end 5 on the long edge of the hook shape through the gas switch, and finally the positioning igniter is connected and adjusted, so that the outdoor gas heating barbecue oven with the special shape and the simple furnace bottom can be used.

Claims (1)
