Abstract

A three-ring fire gas furnace comprises a furnace body (1), a furnace end (2), a burner (3), a control valve component (4) and an injection pipe (5), and is characterized in that the furnace end (2) is provided with an outer ring gas chamber (6), a middle ring gas chamber (7) and a center gas chamber (8), each gas chamber is respectively connected with the gas outlet of each control valve component (4) through the corresponding injection pipe (5) and a nozzle, and the burner (3) is provided with a tooth groove which forms a gas spray hole with the upper end of each gas chamber respectively, so that the three-ring fire burner is formed. The gas-liquid mixed type flame burner has the characteristics of large firepower, independently adjustable application ranges of big fire, middle fire and small fire (or small fire) in each ring, uniform mixing of air and gas, perfect combustion, difficult occurrence of backfire, fire channeling or flameout, difficult occurrence of yellow flame or black smoke, less pollution, safety, sanitation, convenient use and the like.

Description

Three-ring fire gas stove

The utility model relates to a kind of three ring fire gas furnaces, particularly a kind of three ring fire gas furnaces that have separately air chamber independently and induction tunnel thereof.

The gas furnace of atmospheric burning type of the prior art only has two ring fire flames, two rings burning simultaneously during big fire, ring burning in little fire only has the time, its structure is burner and the induction tunnel thereof that a ring-shaped air chamber is only arranged, and interior circle and cylindrical be provided with teeth groove can form with the air chamber upper end in the burner of ring and outer ring fire gas jet orifice, because it only has a ring-shaped air chamber, only be radially to aim at ring-shaped air chamber by induction tunnel, in in little when fire,, the air fuel gas mixture entered by its inertial flow near the ring spray hole and encircle in the ejection and burn, ring-shaped air chamber is full of the air fuel gas gaseous mixture when big fire, inner and outer ring sprays burning simultaneously, but because induction tunnel will be taken into account greatly when design, the instructions for use of little fire, therefore following problem often occurs: 1. big fire is used and is subjected to certain limitation, only can reach 2500～2800KCal/h; 2. little fire uses and must keep certain intensity of fire, and easily causes tempering, scurries fire or flame-out, can not satisfy instructions for use; 3. little when fire be because air capacity is excessive or the injection flow velocity is less, makes to mix inhomogeneously, and makes the burning imperfection; (4) during big fire because gas quantity is excessive, make the burning imperfection, be prone to yellow flame or black smoke.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of to have firepower and reach big fire, moderate heat and the little fiery scope of application greatly, every ring energy independent regulation, air fuel gas mixes, burns perfect, be difficult for causing tempering, scurry fire or flame-out, be not prone to yellow flame or black smoke, pollution less, safety, health, easy to use and reliable three ring fire gas furnaces.

The purpose of this utility model can reach by following measure: three ring fire gas furnaces such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, include body of heater (1), burner (2), burner (3), by-pass valve control assembly (4), induction tunnel (5), it is characterized in that: a. burner (2) has outer shroud air chamber (6), middle ring air chamber (7) and central air chamber (8), and each air chamber is connected with the gas outlet of separately by-pass valve control assembly (4) by each self-corresponding induction tunnel (5) and nozzle respectively.B. burner (3) has respectively with each air chamber upper end and constitutes the teeth groove of gas jet orifice, thereby constitutes three ring fire burners.

The purpose of this utility model can also reach by following measure: three ring fire gas furnaces such as Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, can directly adopt induction tunnel (5) to constitute central air chamber (8) for curved mouthful, to reduce the parts of central air chamber (8), and can guarantee that equally this central air chamber (8) is when big fire and the air feed burning simultaneously of outer shroud air chamber (6) and middle ring air chamber (7), during moderate heat and middle ring air chamber (7) air feed burning simultaneously, only depend on curved mouthful of central air chamber (a 8) air feed that constitutes burning of this induction tunnel (5) when little fire or low baking temperature.

The purpose of this utility model can also reach by following measure: three ring fire gas furnaces as depicted in figs. 1 and 2, its by-pass valve control assembly (4) can be a four-way interlock control valve, its air inlet and source of the gas join, and three gas outlets join with the induction tunnel (5) and the nozzle thereof of corresponding each air chamber respectively.This by-pass valve control assembly (4) can also be the four-way interlock control valve with piezoelectric ceramic ignitor or electronic impulse ignition apparatus.

Operation principle of the present utility model is: combustion gas enters by-pass valve control assembly (4) from air inlet pipe, after pushing its knob igniting, pass through to regulate the knob Position Control to each air chamber air feed and gas flow thereof, have the gas-flow of certain pressure through nozzle this moment, spurt into induction tunnel (5), suck air in certain amount and mixing, and enter into corresponding air chamber, gas jet orifice ejection burning from burner (3), the power of combusting firepower can be by adjusting control valve door assembly (4) with control outer shroud air chamber (6), the air demand of middle ring air chamber (7) and central air chamber (8) realizes, when knob in different angles, the blast tube of each ring fire is in corresponding break-make position, thereby realizes independent control.

The utility model is described in further detail to utilize accompanying drawing:

Fig. 1 is a kind of three ring fire gas furnace structural representations of the present utility model;

Fig. 2 is the plan structure schematic diagram of Fig. 1;

Fig. 3 is the structure for amplifying schematic diagram of the burner part of a kind of three ring gas gas furnaces of the present utility model;

In the three ring fire gas furnaces of the present utility model of Fig. 1, Fig. 2, (1) is body of heater, and (2) are burners, outer shroud air chamber (6), middle ring air chamber (7) and central air chamber (8) are wherein arranged, (3) be burner, (4) are the by-pass valve control assemblies, and (5) are induction tunnels.

In the burner (3) of the three ring fire gas furnaces of the present utility model of Fig. 3, Fig. 4, Fig. 5 and Fig. 6, outer shroud air chamber (6), middle ring air chamber (7) and central air chamber (8) are arranged, central air chamber (8) is the curved notch portion of induction tunnel (5), and (9) are the space between each ring air chamber.

The utility model compared with prior art has:

(1) firepower is big, can reach during big fire more than the 4000KCal/h, more is fit to the use of Chinese dishes " stir-fry ", and has big fire, moderate heat and little fire (or low baking temperature) scope of application that every ring can independently be regulated, and is suitable for various culinary art requirements;
