Abstract
The utility model discloses a gas kitchen range head with secondary air inlet duct and dual spray distributor, this gas kitchen range head's characteristic is: be equipped with the secondary air inlet duct rather than the inner chamber intercommunication at distributor base, the downside is equipped with a plurality of bar air channels in outer distributor, air channel outside-in, slope from bottom to top, become 25~30 jiaos with outer distributor horizontal plane, become 40~45 jiaos with outer distributor plane central line, be equipped with an annular frustum shape bead on outer distributor surface, evenly open the air vent that has a plurality of and distributor base annular air channel intercommunication on annular frustum shape bead, the air vent slope from inside to outside top-down, become 30~35 jiaos with outer distributor axial lead, become 40~45 jiaos with outer distributor plane central line. The gas cooking range can reduce the temperature of a gas ascending pipeline, avoid the tempering phenomenon caused by overhigh gas temperature, realize stable combustion, lead flame to intensively heat the bottom of an appliance, reduce heat loss and improve heat efficiency.
Description
Technical field
The utility model design gas-cooker, particularly a kind of gas burner that is provided with secondary air road and two spray distributor.
Background technology
Embedded gas-cooker more and more receives consumers in general's favor as a kind of high-grade stove and accessory.The auxiliary air air intake mode of present embedded gas-cooker mainly contains three kinds: full upward air intake, following air intake and complete up and down air intake; Wherein adopt the kitchen range ubiquity technological deficiency of air inlet structure down; Must on cabinet, open fresh air inlet during use; And the combustion stability influence to kitchen range is strong when the switch cupboard door, and the kitchen range of the type structure have been in progressively to be eliminated the stage.Full upward air intake is compared with following air inlet structure with full air inlet structure up and down has bigger improvement; But their last air intake mode all adopts horizontal direction directly to replenish auxiliary air to burner, because cooker burner has outer ring fire and middle internal heat to constitute mostly, if directly horizontal direction is replenished auxiliary air to burner; Outer ring fire is the most directly beneficiary that head ought be wherein naturally; And middle internal heat adds that the fresh air passage of distributor below is isolated by the kitchen range panel because most of fresh air " is snatched away " by outer ring fire, and the internal heat oxygen supply is not enough in making; It is insufficient to burn, defectives such as the smoked pot of the kitchen range discharge amount of exhaust gas yellow flame of too high, easy generation.
There is dual mode in general of combustion gas discharge port on the kitchen range distributor in addition: the one, directly on distributor with the saw blade mode saw out bar shaped fire groove; The 2nd, with drill bit on the distributor finished surface with parallel perpendicular to distributor machined surface direction or angled when outward-dipping with horizontal plane; Because fire hole is perpendicular, flame and the bottom of a pan contact area that combustion gas is lighted back formation from the fire hole ejection are bigger, and heating is not concentrated; Thereby cause serious heat loss, it is not energy-conservation to take gas.
The utility model content
The purpose of the utility model is to overcome the gas burner that is provided with secondary air road and two spray distributor that the existing above-mentioned defective of gas-cooker provides a kind of efficient, smooth combustion.
Above-mentioned task realizes by this way: a kind of gas burner that is provided with secondary air road and two spray distributor; Include down air intake burner, center distributor, outer fire seperating device and distributor base; Its improvements are: be provided with the secondary air road that is communicated with its inner chamber at the distributor base, the distributor inner underside is provided with some bar shaped air channels outside, described air channel ecto-entad; Tilt from bottom to top; Become 25 ~ 30 ° of angles with outer fire seperating device horizontal plane, become 40 ~ 45 with outer fire seperating device plane centreline, the distributor surface is provided with the taper type fin of an annular outside; On annular taper type fin, evenly have the passage that several are communicated with distributor base ring-shaped ventilation groove; Described passage tilts from inside to outside from top to bottom, becomes 30 ~ 35 ° of angles with outer fire seperating device axial line, becomes 40 ~ 45 with outer fire seperating device plane centreline.
Through test, technique scheme can be made following further perfect of improving:
Described air channel is 45, becomes 28 ° of angles with outer fire seperating device horizontal plane, becomes 30 ° of angles with outer fire seperating device plane centreline.
Described passage is 80, becomes 33 ° of angles with outer fire seperating device axial line, becomes 43 ° of angles with outer fire seperating device plane centreline.
The utility model is work like this: during burning; Premix good combustion gas get into center distributor and distributor base intracavity from following air intake burner central passage, spray burning through the outer fire seperating device outward with air channel and the passage that distributor base ring-shaped ventilation groove is communicated with again.Meanwhile, the back that is heated, the formula of the concealing secondary air road that is arranged at the distributor base causes the distributor base intracavity with outside air to replenish fresh air combustion-supporting, normal combustion under suction function.
The beneficial effect of the utility model is following:
From the structure of the utility model with and operation principle can learn that owing to be provided with the secondary-air passage that is communicated with its inner chamber at the distributor base, cool ambient air can be taken away a part of heat of distributor base; Reduce combustion gas up-hill line temperature; Fuel gas temperature can not risen so high with kitchen range long temperature burning time, and burning velocity can be not too fast, reduced the possibility that the too high generation tempering phenomenon of fuel gas temperature takes place; Realize the supply of auxiliary air low temperature, make burning more stable.In addition; After distributor has been offered air channel and passage outside, formed two coil vortex formula burning ring behind the fuel gas buring that the outer fire seperating device is sprayed, firepower is more concentrated; Especially passage is to be tilted to setting from outside to inside; Make flame concentrate on the heating appliances bottom, reduced thermal loss, improved the thermal efficiency.Because the utility model combustion gas is fully burnt, and realizes the environmental protection standard emission request of sulfur monoxide more easily.
