Abstract
A burner comprises a base, an outer fire cover and an inner fire cover. The base is provided with the outer outlet and the inner outlet; openings of the outer outlet and the inner outlet are upward; the base is connected with an ejector pipe for fuel gas to enter into. The burner is characterized by also comprising an outer fuel gas base which is in an annular shape; the outer fuel gas base is arranged on the base and covers the outer outlet; the inner gas mixing chamber is formed between the inner side wall of the outer fuel gas base and the inner outlet; the outer fuel gas base comprises a vertical channel and a horizontal channel; the fuel gas of the outer outlet can be introduced into the gas mixing chamber through the vertical channel and the air can be introduced into the inner gas mixing chamber horizontally through the horizontal channel; the outer fire cover covers the upper end surface of the outer fuel gas base to form the gas mixing chamber. Compared with the prior art, horizontal ejecting is performed on the upper inlet air through an inner ring, long horizontal ejecting is still performed on the lower inlet air through an outer ring, and accordingly the problem of the flameout when a cabinet door is opened or closed can be thoroughly solved, the nozzle blocking by liquid spill can be effectively prevented, and meanwhile the overall load can be large and the efficiency can be high.
Description
Technical field
The present invention relates to a kind of burner, be applied to kitchen gas stove.
Background technology
From national policy and citizen requirement, low-carbon emission and low energy consumption, become a problem important in domestic gas tool.At present normal atmospheric formula burner has been accomplished ultimate attainmently to low emission and high efficiency, has realized and has accomplished thermal efficiency 60%(GB16410-2007) combustion technology.The advantage of upper inlet wind type burner is apparent, the impact safe, clean, embedded gas utensil is not subject to cupboard door switch etc.But upper inlet wind type burner also cannot reach thermal efficiency 60%(GB16410-2007 reliably).
Large load domestic gas tool, accomplishes efficient energy-saving, and the most important is the induction tunnel with certain length, wherein includes mixing tube, diffuser pipe, aditus laryngis etc.Although can singlely give up mixing tube, aditus laryngis or diffuser pipe angle are set to 0.But the length of induction tunnel is necessarily to need to guarantee.At present, fairly proper although the flaming system of burner is done, the structural limitations due to upper air inlet burning, causes burner induction tunnel generally partially short, has affected the injection of burner.
In prior art, upper inlet wind type burner has been done to a lot of improvement, referenced patent number is the gas stove burner > > (Granted publication number is CN200993364Y) of the Chinese utility model patent < < full upward air intake of ZL200620155563.9, this patent has adopted the induction tunnel of overlength, not only made complex structure a lot, and be only applicable to the kitchen range of even number kitchen range eye, apply more restricted.
Application number is the embedded burner of household gas cooker > > (publication number CN101446415A) of open < < multiinjector of Chinese invention patent application of 200810220263.8, large flow, full upward air intake, in this application, induction tunnel can only be confined in the diameter range at burner place, induction tunnel is still partially short, injection effect is not good enough, fills into air less.
The patent No. is Chinese utility model patent < < stove burner with complete upper air feeding > > (Granted publication number is CN201715507U) of ZL201020242405.3, more than this patent is placed in panel by burner, though realized well upper air inlet, but whole burner exposes with more than stove panel, affected the structure of burner, affect product design simultaneously, simultaneously to user's maintenance, sanitation in inconvenience.
The patent No. is Chinese invention patent < < Backfire-proof upside-entrainment air-adjustable gas cooker > > (Granted publication number is CN102147117B) of ZL201110112722.2, when installing and using, the gas kitchen ranges of this patent needs again perforate on panel or liquid-bearing pan, in order to enter air, visible installation is more loaded down with trivial details.
In sum, easily there is the folding cupboard door problem of stopping working in lower air intake, adds becoming better and better that present cabinet sealing property does, so occur that the flame-out problem of switch cupboard door kitchen range is more and more outstanding; Full upward air intake does not have the flame-out problem of folding cupboard door, but in diameter range effectively, thermic load is difficult to do greatly, efficiency is done high difficulty.Upper inlet wind type burner often adopts vertical injection in addition, and nozzle is easily stopped up by discharge.
Summary of the invention
Technical problem to be solved by this invention is for the above-mentioned state of the art, to provide a kind of flame-out and thermic load of folding cupboard door that can thoroughly solve can make high burner.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of burner, comprise pedestal, outer fire cover and inner fire cover, aforesaid pedestal is provided with outer delivery outlet and the interior delivery outlet that opening all makes progress, aforementioned pedestal is connected with the induction tunnel entering for combustion gas, characterized by further comprising an outer burned gas base in the form of a ring, this outer burned gas base is located on pedestal and is covered outer delivery outlet, and, mixed air cavity in forming between this outer burned gas base madial wall and interior delivery outlet, described outer burned gas base has can be guided to the combustion gas of outer delivery outlet the Vertical Channel of mixing chamber and air water level land can be incorporated into the horizontal channel of aforementioned interior mixed air cavity, described outer fire cover is covered on this outer burned gas base upper surface and forms mixing chamber.
Further, the interior delivery outlet of described pedestal is provided with interior burned gas base, and described inner fire cover is covered on interior burned gas base, and, between aforesaid interior burned gas base outer wall and outer burned gas base inwall, form the interior mixed air cavity of ring-type.
Further, described induction tunnel comprises the outer induction tunnel communicating with outer delivery outlet and the interior induction tunnel communicating with interior delivery outlet, and aforesaid outer induction tunnel has the introduction passage entering for air.
Further, the upper surface of described outer burned gas base is provided with a gasket ring, and the periphery wall of this gasket ring extends upward formation limiting section, described outer fire cover be positioned on this gasket ring and lateral wall and limiting section inside offset.
Compared with prior art, the invention has the advantages that: by special outer burned gas base, realized air intake under the horizontal injection upper air inlet of interior ring and the long horizontal injection of outer shroud employing simultaneously, can thoroughly solve the flame-out problem of folding cupboard door like this, can effectively prevent discharge plug nozzle again, and total load can be done greatly, is convenient to do high efficiency, compact overall structure is reasonable, practical.
