Abstract

The utility model relates to a fire cover for burners in gas cookers, which is characterized in that the inner ring of the ring-link fire cover is a hollow hole for the supply of a secondary air in combustion; the side of the hollow hole is provided with a spiral fire slot in circumferential direction, so that the gas sprayed from the fire slot can mix with the secondary air from the hollow hole more directly for combustion. Owing to the spiral arrangement of the fire slot on the circumference of the side of the hollow hole, the combustion flame is more concentrated to produce a higher thermal efficiency with more complete combustion, therefore is particularly suitable for Chinese stir-frying with high fire.

Description

A kind of gas kitchen ranges burner fire lid

The utility model is the burner fire lid that a kind of gas kitchen ranges is used.

The fire output hole distribution of the burner fire lid of prior art is modal three kinds: a kind of is that fire hole is distributed on the excircle of fire lid, and second kind is the upper end face part that fire hole is distributed in the fire lid, and the third is all to be distributed with fire hole with upper end face part on excircle.First kind of fire lid is because fire hole is distributed on the excircle, and its flame is concentrated inadequately, and heat is easily by the absorption of air of surrounding environment, so the thermal efficiency is lower.Second kind of its fire hole of fire lid is distributed in the position, upper end of lid, and its flame is nearer from the bottom of a pan, although the thermal efficiency improves, flame contacts with the bottom of a pan is in-plant, separates out carbon black and carbon monoxide easily, and auxiliary air is additional also direct inadequately.The third fire lid, the defective that exists second kind of fire to cover equally.Hence one can see that, and all there is certain deficiency in the combustibility of above-mentioned three kinds of fire lids.

It is a kind of that the purpose of this utility model is to provide, can overcome above-mentioned defective, change the distribution of its fire hole, make fire hole be distributed in along the circumferential direction going up of interior annulus bore side, so both made that auxiliary air is easier directly to be contacted with fire hole, make burning more abundant, can make flame combustion more concentrated again, combustion thermal efficiency is higher.

Realize the technical scheme of the utility model purpose, concrete structure is such, adopts annular fiery cap body 1, and the interior ring of annular shape fire lid is an emptying aperture 2, and along the circumferential direction offers the fiery groove 3 of spiral distribution in the side of emptying aperture.

Burner fire lid of the present utility model and original technology ratio, because the fire hole of former technology fire lid is distributed on the excircle or on the upper surface, and the fire hole of the utility model fire lid is on the circumference of annulus bore side in being distributed in, and shape distributes in the shape of a spiral, thereby make the easier and combustion gas mixing of auxiliary air, combustion flame is also more concentrated, has thermal efficiency height, the low characteristics of carbon monoxide content in the flue gas.

Description of drawings:

Fig. 1 is the burner generalized section of the utility model embodiment

Fig. 2 is the front view of the utility model embodiment fire lid

Fig. 3 is the rearview of the utility model embodiment fire lid

Embodiment:

As depicted in figs. 1 and 2, burner is annular, and is made up of a combustion chamber 4 and the burner fire lid 1 that matches.From Fig. 2 and Fig. 3 as can be known, ring is an emptying aperture 2 in the fire lid, and along the circumferential direction offers the fiery groove 3 of spiral distribution in the side of emptying aperture.Also as can be seen from Figure 1, formed the fire hole 5 of burner after the fiery groove that covers of fire 3 and the combustion chamber assembling.

The described fire lid of embodiment is along the circumferential direction gone up because fiery groove is opened in the emptying aperture side of interior ring, and is that spiral distributes, thereby make the easier and combustion gas mixing of auxiliary air, combustion flame is also more concentrated, has therefore improved combustion thermal efficiency, also makes burning more abundant simultaneously.

Claims

The burner fire lid that a kind of gas kitchen ranges is used, lid (1) is annular, ring is emptying aperture (2) in it, and interior ring side along the circumferential direction offers the fiery groove (3) of spiral distribution, it is characterized in that: set fiery groove (3) is to be opened on the circumference of interior annulus bore (2) side, and shape distributes in the shape of a spiral.
