Description

The spiral-flow type efficient gas burner

Technical field:

The utility model relates to kitchen range, particularly a kind of gas burner.

Background technology:

The gas burner that use in existing various kitchen, its blast tube and air duct mostly are the ejection type bypass structure, and two kinds of gas incorporation times are short, cause mixed effect poor, and the thermal efficiency is low, also is that energy utilization ratio is low, and consumer's energy expenditure is higher.

Summary of the invention:

The purpose of this utility model provides a kind of combustion gas and air mixed effect good energy-conservation gas burner.

Burning seat of the present utility model is installed an air jet pipe at the bottom of the chamber, the pipe end, be communicated with main air inlet pipe, the seat wall opening, constitute the mixed flow chamber in it, it is characterized in that there is an eddy flow platform burning seat top, the shoulder of diameter greater than platform made, circumferential arrangement eddy flow plate on the shoulder for the circle platform in this eddy flow platform top under the disc; The center-hole diameter of the jet thrust that is threaded with the burning seat is greater than eddy flow platform circle flat surface diameter and concentric installation, circumferential weld between the two constitutes main fire-fighting gas ring shape mouth, the outer rim of jet thrust and burning seat outer ring closely connected cooperation of upper end, constitute little fiery mixed flow ring cavity in it, the ring cavity bottom communicates with auxilliary air inlet pipe, and the top has the little fire-fighting pore of circle spacing arrangement.Burning seat seat wall opening place can be connected with the gas outlet of air blast.The air jet pipe of the misalignment burning seat inner axes of blower export.Eddy flow platform bottom surface is shaped on body, and the tube wall bottom is threaded with the burning seat, and tube wall has a plurality of through holes.The air jet pipe upper end is connected with eddy flow platform bottom centre, and the lower end was threaded with the end in the burning seat.

The eddy flow platform that the utility model is installed at the jet thrust center, the eddy flow plate of the circumferential arrangement that is provided with on its shoulder, make gaseous mixture enter the formation eddy airstream from ecto-entad between the eddy flow plate, increased mixed effect, combustion efficiency is obviously improved, and be eddy airstream from the gaseous mixture of ring jet mouth ejection, its burning fire head also is spiral type along rising on the bottom of a pan, increased the time of contact of duration and degree of heating and pot, the promptly identical duration and degree of heating that gas quantity produced prolongs with a pot body time of contact, thermal efficiency raising.For air blast formula forced air inlet type, make the air-flow that enters in the chamber, form eddy current because blower outlet is non-over against burning seat axis, the contacts fuel gas time that itself and air jet pipe come out is longer, the mixed flow better effects if.Because the energy had both been saved in the raising of the thermal efficiency, had also reduced consumer's energy expenditure.According to test, under thermic load situation identical gas quantity and identical, the utility model can shorten burning time about 15% than common burner.

The specific embodiment:

Figure 1 shows that the need that are suitable for using in the restaurant, restaurant have the air blast burner of big firepower.Burning seat 2 profiles can be shown that by Fig. 1, Fig. 2, Fig. 3 its top is three concentric turns, and its underpart is a cylinder tube shape, and tube wall has air inlet 12, can be connected with air blast 13 air outlets.The axle center of this air inlet misalignment cylindrical seat makes air intake produce vortex along the seat wall in mixed air cavity 11.Seat 2 bottom centre's spiral shells connect the air jet pipe of erectting 5, and communicate with main air inlet pipe 10, and circle connects with body 4.1 spiral shells of eddy flow platform 4 bottoms in seat 2 upper ends, has a plurality of through holes 4.4 on the tube wall of body 4.1; The shoulder 4.2 of diameter greater than it made for circle platform 4.5 in eddy flow platform 4 tops under this platform, a plurality of deflectors 4.3 of pressing the secant direction of circumferential arrangement on the shoulder 4.2, and its shape is with reference to Fig. 4, and gaseous mixture enters the interval between each deflector.

Burning seat 2 top centre circles are shaped on internal thread, with the body 4.1 spiral shells company of firn-jet head 3 lower ends.Burning seat 2 top collar wall and firn-jet head 3 outers overlap joint, firn-jet head 3 tops have the little fire-fighting gas port 3.1 of circumferential arrangement near outer rim, constitute gas-air mixing ring cavity 7 in it, have a through hole at the bottom of the chamber and be communicated with auxilliary air inlet pipe 9, mark 9.1 is empty gas entering opening among the figure.

Jet thrust 3 upper ends have center big hole 3.2, as shown in Figure 5, its lower end body 4.1 screws in the centre circle of seat 2, this big hole just is being placed in outside the round platform 4.5, the diameter of big hole 3.2 leaves circumferential weld between the two greater than the diameter of round platform 4.5 after the assembling, this circumferential weld is the jet annular mouth 6 of big fire, adjust the height of firn-jet head 3, can adjust the flame direction of big fire.Mark 1 is the double pot of a fire trap hood frame among the figure.

Valve 8 is a packet type switch, replaces the existing product big and small fire respectively by the structure of single Air Valve Control.This stacked switch is a three-port structure, makes band switch formula structure in it.When pulling swing handle, open auxilliary air inlet pipe 9 when initial earlier, the little fire in outer ring that ignites of sparking simultaneously continues to pull swing handle, and main air inlet pipe 10 is opened, and starts air blast 10 simultaneously, and interior ring big fire is ignited by the little fire in outer ring.

During work, main jet tracheae 5 sprays combustion gas, and mixes with air eddy that air blast 10 is come in and to rise in the body 4.1, comes out from tube wall circular hole 4.4, from entering at interval between the deflector 4.3, sprays from circumferential weld mouth 6 again.Because its labyrinth distance, combustion gas and air incorporation time are long, mix fully.

Air blast 10 motors adopt brshless DC motor, and its advantage is safe voltage (direct current 24V), can avoid the 220V AC power of old product, just in case electric wire leaks electricity, and the electric shock accidents that the cook can cause during with the iron spoon, and brushless dc engine efficiency height, power consumptive province.When omitting air blast 10, can be used as household gas range, because hot-air rises and cyclonic action, efficiency of combustion still is higher than the general gas kitchen range.

Fig. 6 has represented another kind of eddy flow platform structure.Its no perforate body in bottom, direct and eddy flow platform 4 bottoms, air jet pipe 5 tops are connected, and have the supporter of eddy flow platform simultaneously concurrently, and the mixed flow effect is approaching, but simple in structure.
