Description

A kind of primary air regulating device of upper inlet wind type burner

Technical field

It adjusts and fills the utility model relates to the primary air of a kind of kitchen range component more particularly to a kind of upper inlet wind type burner It sets.

Background technique

The burner of present household cooker is mostly pre-mixing type combustion apapratus, its working principle is that: combustion gas under a certain pressure, It is flowed out with certain flow velocity from nozzle, attracts surrounding a certain amount of by the ejector action of combustion gas energy itself into ejector pipe Air, this partial air are known as " primary air ", primary air and combustion gas and mix in ejector pipe and burner mixing chamber, then It flows out, burns through fire hole, attract air-breathing from flame periphery in combustion process, this partial air is known as " secondary sky Gas ".It is easy to generate in the use process of burner from flame, from flame Producing reason, usually primary air surplus, fire hole The problems such as calorific intensity is excessive.The soakage for controlling primary air is the best method solved the problems, such as from flame.Since primary air is inhaled Enter amount to be difficult to control, so there is a problem of mostly in present upper inlet wind type burner insufficient from flame and fuel gas buring.As in State's patent: " a kind of high-power air inlet burner (CN207378824U) ", including pedestal and bracket are connected with air inlet on pedestal Head, air inlet head are equipped with the first suction nozzle, the second suction nozzle and air feeding in center mouth, and pedestal draws equipped with the first ejector pipe, second Penetrate pipe and intermediate ejector pipe, the first ejector pipe and the second ejector pipe extend to form outward respectively the first inlet channel lower part and Second inlet channel lower part, bracket are equipped with the first inlet channel top and the second inlet channel top, when bracket fixation is set When being placed on pedestal, the first inlet channel top and the first inlet channel lower part cooperatively form the first inlet channel, the second air inlet Upper part of channel and the second inlet channel lower part cooperatively form the second inlet channel, the first inlet channel and the cooperation of the second inlet channel Outer annular inlet channel is formed, the intermediate gas outlet with intermediate ejector pipe cooperation is additionally provided among bracket.

Summary of the invention

It is simple that the utility model provides a kind of structure, can effectively prevent in the one kind for from flame, controlling primary air surplus Enter the wind the primary air regulating device of burner；It solves upper inlet wind type burner existing in the prior art not and can control primary sky Gas inlet is easy to produce from flame, the bad technical problem of combustion efficiency.

The above-mentioned technical problem of the utility model is solved by following technical proposals: the one of a kind of upper inlet wind type burner Secondary conditioner, it is characterised in that: including being mounted on burner intracavitary nozzle arrangement and adjustment means open at one end, nozzle One end of component connects with the air inlet on burner, and the other end of nozzle arrangement connects with the ejector pipe on burner, in nozzle structure Part and ejector pipe joint are equipped with adjustment means.Nozzle arrangement connects with air inlet, controls gas inlet amount, benefit by nozzle arrangement Air inlet amount is adjusted with adjustment means, to achieve the purpose that prevent from flame.It is primary empty by opening up atrium on burner Gas control device is arranged in atrium, can effectively utilize space, compact-sized, completes to adjust.Atrium it is opening up, Distributor seat is located above burner, and distributor seat spacing leaves the opening in oral cavity, and there are also certain distances, to allow air to flow into out In oral cavity, atrium provides an accommodating chamber to air, and the air capacity of entrance is then controlled by adjustment means.

Preferably, the nozzle arrangement includes nozzle body, nozzle is equipped on nozzle body.

Preferably, the adjustment means packet air flap, the air flap are located at one end of nozzle body, by adjusting The distance between air flap and primary air import control primary air inlet.Shifting of the air flap on the axial direction of nozzle It is dynamic, the injection volume of primary air is adjusted by control the distance between air flap and primary air import, to reach control Purpose from flame.

Preferably, being socketed with spring on the nozzle body of nozzle arrangement, one end of spring is connected to nozzle arrangement On nozzle, the other end of spring is connected on the air flap of adjustment means.Using elastic force the resisting air flap of spring, thus Air flap will not be loosened in the axial direction, high control precision is mentioned.

Preferably, the upper end opening of the atrium, atrium includes the cavity wall of annular, the cavity wall of annular with draw It penetrates the pipe side that connects and offers primary air import, primary air import connects with ejector pipe；In annular cavity wall and air inlet phase Side is connect equipped with fuel gas inlet, fuel gas inlet connects with air inlet.After inlet charge, led by two vertical with air inlet Combustion gas is introduced into nozzle arrangement by pipe, and nozzle arrangement jet is mixed with the primary air in atrium, by primary air Import enters in ejector pipe.Primary air import is directly provided in cavity wall, facilitates the adjustment of adjustment means.

Preferably, the shape of primary air import opened up on the shape of the air flap and atrium is identical.Wind Door piece axially moves to the end of nozzle body, primary air import is blocked completely, primary air amount is zero, when air flap edge When axially moving to nozzle direction, primary air import is opened wide completely, and primary air air inflow is maximum.

The primary air regulating device of burner has following advantages: structure is simple, and atrium is arranged in burner, rationally cures With the space in burner, primary air regulating device is placed in atrium, effectively adjusts primary air inlet, thus Control the efficiency of combustion that kitchen range are turned up from flame；The air door chip architecture of primary air inlet conditioner is simple, can be effectively controlled The adjusting section of primary air inlet, intake is big.
