Description
Technical field
The utility model relates to the kitchen range field, especially relates to the fire lid and has the gas-cooker that this fire covers.
Background technology
The thermal efficiency of kitchen range is core index of weighing the kitchen range properties of product, and the influence factor of this index has burner volume, flame distribution state, grate height, replenish air and mixability etc.
Burner on the market has the normal burner of infrared burner and minor diameter at present.Infrared burner adopts the complete pre-mixing type burning, namely improves burner structure combustion gas first and enough air before burning are mixed fully.The power of infrared burner is less, firing rate slow, flames of anger heating does not meet domestic culinary art situation, and the burner volume is bigger, and the heating board fire hole easily stops up, is difficult to cleaning.
The burner of minor diameter generally has only outer ring fire, and does not have interior ring fire, and thermic load is all less usually, fire hole dense arrangement simultaneously, and auxiliary air replenishes difficult, easily interferes between the flame and causes phenomenons such as Huang Yan and CO content in smoke height.
The utility model content
The utility model is intended to solve at least one of technical problem that exists in the prior art.
For this reason, a purpose of the present utility model is to propose a kind of fire lid that improves the thermal efficiency.
According to fiery lid the of the present utility model, comprising: interior ring, described interior ring have along being somebody's turn to do the interior a plurality of fiery groove that radially connects that encircles, and described a plurality of fiery grooves are along being somebody's turn to do interior encircle circumferentially spaced apart; And outer shroud, described outer shroud is set in outside the described interior ring, described outer shroud with described in limit the blast tube of the annular that is communicated with described fiery groove between the ring, the upper surface sealing of described annular fuel gas passage, described outer shroud has a plurality of fire holes, described a plurality of fire hole is circumferentially spaced apart along this outer shroud, and the inner of each described fire hole is communicated with described blast tube and extends upward obliquely outward from its inner.
According to fire lid of the present utility model, by ring and outer shroud in being provided with, make combustion gas from interior ring and outer shroud, to spray simultaneously and to be lighted, thereby increased the thermic load of gas-cooker, fire hole owing to outer shroud extends upward outward obliquely from its inner again, the bottom of a pan was more pressed close in the flame high-temperature region when thereby feasible combustion gas from the fire hole ejection was lighted, and then improved the thermal efficiency of gas-cooker, reduced energy loss.
In addition, also have following additional technical feature according to fire lid of the present utility model:
According to embodiment more of the present utility model, each described fiery groove comprises fiery groove section and the groove section of getting angry down, described get angry the groove section from the upper end of described down fiery groove section with described in the radius of ring become the mode of first predetermined angular inwardly to extend with being inclined upwardly, described under fiery groove section vertically extend.
Fire lid according to the utility model embodiment, because the fiery groove in the interior ring is divided into get angry groove section and following fiery groove section, the interior radius that encircles of the groove Duan Yiyu that gets angry becomes the mode of first predetermined angular inwardly to extend with being inclined upwardly, thereby make combustion gas spray in fiery groove to cover angled mode with fire, under the promotion of combustion gas kinetic energy, combustion gas forms swirling eddy in the bottom of a pan, after combustion gas is lighted, flame can rotate under the bottom of a pan, prolong the time of staying of flame, make the heat-exchange time of the bottom of a pan and air reduce, the thermal efficiency improves.Again since down fiery groove section vertically extend, thereby be convenient to the machine-shaping of fiery groove, can improve the flame transmission direction when being lighted by the combustion gas of fiery groove simultaneously, increase the contact area of combustion gas and air, avoid occurring phenomenons such as yellow flame and CO content height.
Particularly, described first predetermined angular is 30 degree～40 degree, and described fire hole extends upward obliquely in the mode that becomes second predetermined angular with horizontal plane and described second predetermined angular is more than 30 degree.
Preferably, described first predetermined angular is 35 degree.
