Description
Technical field
The utility model belongs to gas kitchen ranges, relates in particular to a kind of air intake gas kitchen ranges of going up.
Background technology
Modern kitchen requires installing and using of built-in type cooker must guarantee that all the needed air of burning is from obtaining more than the panel, the existing on the market air intake kitchen range of going up comprise burner base, induction tunnel, external ring fire cover and middle internal heat lid, induction tunnel is connected with burner base, but induction tunnel inlet and burner base distance are bigger, because last air intake requires all air to enter from panel top, the position of present induction tunnel is lower, air enters the induction tunnel inlet from panel top distance is far away, cause the ejector capacity of existing induction tunnel poor, the air capacity that enters in the induction tunnel is little, combustion gas and primary air undercompounding, cause the thermal efficiency generally lower, only about 51%, energy loss is serious, wastes energy.Because ejector capacity is poor, cause the power of gas kitchen ranges to be difficult to do greatly simultaneously, do not meet the custom that Chinese's cooking needs the big fire quick-fried.Simultaneously more so-called on the market upward air intake kitchen range are not to go up air intake completely, but perforate comes the required air of aftercombustion on panel, soup juice or culinary art foreign material easily enter into kitchen range housing the inside from the sky on panel top, not easy-clear and cleaning, time is meeting breed bacteria and peculiar smell for a long time, thus harm consumer's health.
Summary of the invention
The utility model provides a kind of air intake gas kitchen ranges of going up, and it is insufficient because of the burning that the ejector capacity difference is caused to solve existing gas kitchen ranges, and efficient is low, and the problem that power is little is to reach national energy-conserving and environment-protective standard.
A kind of air intake gas kitchen ranges of going up of the present utility model comprises burner base, induction tunnel, external ring fire cover and middle internal heat lid, it is characterized in that:
Described burner base is the annular with center induction tunnel, the annulus upper surface has cannelure, burner base side symmetry has two tonifying Qi holes, be communicated with the annular through-hole between annulus and the center induction tunnel respectively, the burner base bottom surface has equally distributed leg along the edge, the burner base bottom surface is the tangential direction symmetry with described annulus and is connected two side induction tunnels, and two side induction tunnels are communicated with described cannelure respectively;
Described external ring fire cover is an annular, its lower surface has the circular circuit corresponding with described burner base cannelure, the fire hole that the external ring fire cover excircle has even distribution, is communicated with circular circuit, described external ring fire cover places described burner base upper surface, and the circular circuit of external ring fire cover and burner base cannelure constitute mixing chamber; The internal heat lid is set up in external ring fire cover annular central authorities in described, is positioned at directly over the induction tunnel of center;
Combustion gas injection pedestal is a box-like, its bottom centre is equiped with center gas nozzle and center combustion gas interface, combustion gas injection pedestal upper surface diagonally opposing corner is equipped with two jet pipes, described burner base leg is connected with combustion gas injection pedestal by screw, and described two jet pipes are aimed at two side induction tunnel inlets respectively; Described center induction tunnel is positioned at directly over the gas nozzle of center.
The described air intake gas kitchen ranges of going up is characterized in that:
Distance between described side induction tunnel inlet central horizontal face and the burner base tonifying Qi hole lower surface is 20～24mm.
The described air intake gas kitchen ranges of going up is characterized in that:
The fire hole that the annular inner periphery of described external ring fire cover has even distribution, is communicated with circular circuit, external ring fire cover inner periphery fire hole number is less than excircle fire hole number.
Generally speaking, the size of external ring fire cover with and top fire hole number and position determined the degree that firepower is concentrated and the situation of burning.If fuel difference, gas-cooker power difference, then the condition of the formation of its CO and NOx is different with the position, then the parameters such as number of external ring fire cover and fire hole are just different, by adjusting its relative dimensions, make fuel in suitable zonal combustion, both helped burning fully, can suppress the generation of NOx again, to reach the high-efficiency cleaning burning.
During the utility model work, burner base places on the panel, need not out fresh air inlet above the panel, fuel is by two jet pipes and the ejection of center gas nozzle, injection portion of air (primary air) enters mixing chamber by the side induction tunnel under certain pressure, and enter middle internal heat lid by the center induction tunnel, fuel under certain pressure respectively by two jet pipes on the combustion gas injection pedestal and the ejection of center gas nozzle, then the external ring fire cover of installing from mixing chamber top and internal heat cover the fire hole ejection of face, auxiliary air can be replenished by burner base top air admission hole, the auxiliary air demand is not high, makes the size of external ring fire cover suitably to reduce, and has increased the time of contact of high-temperature flue gas and pot face, reduce energy loss, make heating more even, heat absorption efficiency is higher, and CO and NOx discharger are very low.
Distance between the utility model side induction tunnel inlet central horizontal face and the burner base tonifying Qi hole lower surface shortens to 20～24mm, make the distance that enters the mouth from the air approaching side induction tunnel on panel top shorten, two jet pipe diagonally opposing corners are arranged, near induction tunnel, played gather qi together, strengthen the effect of induction tunnel ejector capacity, under the identical situation of gas quantity, strengthened the air intake ability, make that the air content in the gaseous mixture increases behind the injection.Induction tunnel rear portion bending makes combustion gas and air further spread mixing simultaneously, and it is more even to make that the mist that enters mixing chamber mixes, and it is more abundant to burn, and gas-cooker power increases, and meets the requirement of compatriots' cooking needs vigorous fire.
Owing to need not out fresh air inlet above the panel, the enclosure interior that can not enter into easy-clear not or cleaning of soup juice and foreign material or small insect and so on can breed bacteria or peculiar smell, helps consumer's health.
Proof adopts gas-cooker of the present utility model by experiment, and the heat absorption efficiency of pot face has reached 55%, and the CO discharge capacity is below 400ppm simultaneously, and the NOx discharge capacity requires index far below national energy-conserving and environment-protective below 300ppm.
