Abstract

A gas range with both convection heat transfer and radiation heat transfer features that on the basis of existing range, the diameter and arrangement of flame channels of porous ceramic radiation plate are changed to make the flame rise spirally and vertically. A secondary air inlet channel is additionally arranged on the plane of the perforated plate to form horizontal secondary air inlet; lifting the inner pipe at the head part of the burner, and reserving vertical secondary air to form a three-dimensional system; three small upright posts are additionally arranged at the head part of the fire fighting; the shape and the structure of the pot bracket are changed, and the heat transfer contact surface is reduced; the design of the double-fire switch is changed, so that the big fire and the small fire can be respectively combusted and overlapped.

Description

Efficiency energy saving gas range

The utility model relates to the gas-cooker field.

Known gas-cooker all is a burner process injection stream, produces negative pressure and sucks primary air, through injector, form gaseous mixture, spray from fire hole at a certain angle, after being lighted from the chrysanthemum head, carry out mixing the second time with air, make its normal combustion, yet this angle is in the heat of convection current is transmitted, refraction, many heats that scatter and disappear reduce the thermal efficiency.Kitchen range are of a specified duration more service life, and the thermal efficiency is low more, and thermal efficiency curve is bigger with the big minor swing of switch aperture.After infra-red radiator is used, brought new hope for the reform of gas kitchen ranges.At present, many producers are all actively developing porous ceramic plate infrared radiation gas-cooker.This gas-cooker has changed the thermaltransmission mode that certain refraction angle is arranged, and becomes vertical infrared radiation heat transfer type, its simple structure, cleaning, thermal efficiency height, and the thermal efficiency and kitchen range noncausal relationship service life change when big even rise to close rising degree, and the thermal efficiency curve fluctuation not quite.But this gas-cooker of developing at present, burner have been cancelled center secondary air passage, and area is all very big, uses little aluminum pot very inconvenient, therefore, and generally only as warming oneself by a fire stove.Because of not meeting people to the kitchen range shape, the traditional habit approval that the duration and degree of heating size had formed has already influenced its popularization.And if shine the approval of this custom, adopt the small size burner, the convection current and the width of cloth are penetrated the mode of heat transfer arranged side by side, the not only slightly inadequate CO content of porous plate core auxiliary air amount but also do not reach ideal standard.

This reality is made novel purpose: be exactly under the custom view prerequisite of people to the approval of traditional kitchen range shape size, change the spread geometry of porous ceramic plate flue, keep and dwindle the secondary air passage at burner center, increase horizontal secondary-air passage, change the shape of kitchen range coil support, change the structure of two fiery burnt gas switch etc., make flame vertical lifting in the shape of a spiral, and then improve the resultant effect of combustion gas tool.

The utility model is to realize like this.At first, be exactly that the vertical symmetry anyhow of porous ceramics plate hole is arranged, change the concavo-convex arrangement of helix into, and leave the horizontal secondary-air passage in three roads, compensation core burning required air quantity makes that flame rises in the shape of a spiral, firepower is concentrated fast, the hot transfer strength height of speed.Secondly, be exactly around fire-pan, evenly add three outstanding posts, support small-sized aluminum pot and use; Change the shape of kitchen range coil support simultaneously, minimizing and kitchen range and contact-making surface, reduce heat leakage, form kitchen range face and support certain clearance,, the part auxiliary air is flowed to the fire-pan horizontal direction through this gap, both cool off the reduction panel temperature, and made auxiliary air give heat again, helped promoting abundant burning.Once more, single exactly fire-pan center secondary air passage will dwindle, and center auxiliary air flow velocity is restricted; Two fire-pans change the design that rises the pass, large and small fire is burnt respectively, and (but big fire is when burning separately, should keep certain thermic load) during big fire burns, a little fiery injector suck air, secondary air passage in center when burning as porous ceramic plate, during little fire burns, big fire is on every side extinguished, thereby improves the combination property of gas-cooker.

The utility model is compared with former gas-cooker, and apparent size, shape do not have much changes, adapts to people's sanctioned by usage, and it is easy to be accepted by people.It improves the secondary air passage by changing the arrangement of porous plate hole, changes the shape of support and the structure of two fiery switches, optimizes the kitchen range performance.Its combustion system is warmed oneself by a fire between the stove between chrysanthemum head burner and infrared ray, and heat is transmitted existing atmospheric burning type convection heat transfer' heat-transfer by convection, has the flameless combustion width of cloth to penetrate heat transfer type again, and therefore, resultant effect is obvious, and people take like a shot.

Below in conjunction with accompanying drawing, the utility model is further described

Fig. 1-the 1st, the front view of porous ceramic plate

Fig. 1-2 is the vertical view of porous ceramic plate

Fig. 2 is the front view of single ignition combustor embodiment

Fig. 3 is the vertical view of single ignition combustor embodiment

Fig. 4 is the front view of high foot support

Fig. 5 is overlooking of high foot support

In the accompanying drawings: 1, the protruding eye height of porous ceramic plate, 2, porous ceramic plate celophthalmia height 3, porous ceramics board diameter 4, gradually thin protruding eye arranges 5, gradually thin celophthalmia is arranged.6, horizontal secondary air passage 7, center secondary air passage (single ignition combustor) or flammule road (two ignition combustor) 8, support all gap 16, gas-cooker planes between pipe 13, pot strong point 14, pan bracket pin 15, pan bracket circle and the kitchen range plane in bonding plane 11, single ignition combustor center secondary air passage 12 of increasing, the burner head of aluminum pot post 9, porous ceramic plate 10, ceramic wafer and burner head

Fig. 1-1, Fig. 1-2 are the shape and the structural maps of porous plate, it is to change traditional flue of arranged vertical in length and breadth, taking spiral embossing flue Diameter Gradual Change arrangement 54 row concavo-convex alternately, it is three zones that three roads horizontal secondary air passage equity is divided equally, and be provided with horizontal secondary air passage 6 in three roads and secondary air road, center 7, to improve combustion position.Center secondary air passage 7 has 2 effects, and as bonding with single ignition combustor head, this eye is the secondary air passage; Bonding with two ignition combustor heads, the secondary air passage when this is big fire burns is again that the flue of little fire when burning separately (switch by two fiery switches, but the switch switched design need have overlapping moment, unlikely switching cutoff.)

In the embodiment of Fig. 2 to Fig. 3 list ignition combustor, pipe in the present known burner head 12 is raise, with porous plate bonding plane 10 levels around the head.Change former fiery lid mode into the porous ceramic plate mode owing to this is novel.Can't support small-sized aluminum pot, so around head, set up three posts 8 to increase practicality and comfort level.

In Fig. 4, Fig. 5, be not difficult to find out, be on former pan bracket basis, evenly to increase by three high footings 14 to make cooker holding ring and kitchen range plane 16 form the gap 15 of a 3-10MM, the one, reduce the contact-making surface and the heat transmission of original bracket loop and kitchen range face and scatter and disappear, the 2nd, the horizontal secondary air passage of formation, give hot-air, change general burning.

From institute's drawings attached as can be seen, the utility model to known combustion gas tool arrange at ceramic plate hole, combustion system, supporting construction mode and rise the big improvement of all contrasting of pass system.When kitchen range design, a new thinking is provided, can receive apparent in view resultant effect.
