Description

Burner

Technical field

The utility model belongs to home furnace field, is specifically related to the burner of cooking stove.

Background technology

The existing burner with three ring firepowers operationally, because auxiliary air supplements difficulty, wherein ring fire is difficult to realization and burns completely, thus a large amount of nitrogen oxide can be produced, the harm of nitrogen oxide to human body is larger, therefore improve combustibility and burning efficiency, make middle ring fire Thorough combustion, very necessary with the discharge reducing NOx, CO.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides ring fire Thorough combustion in a kind of realization, improves the burner of efficiency of combustion.

The utility model solves the technical scheme that its technical problem adopts: a kind of burner, comprise burner, distributor and the central flame cap coordinated with distributor and ring-shaped fire cover, burner, distributor and ring-shaped fire cover surround a gas mixing chamber communicated, the lateral wall of ring-shaped fire cover is circumferentially with multiple through hole, the madial wall of ring-shaped fire cover is circumferentially with the groove of multiple through madial wall, lead to the hole site and groove location have difference in height.

It is poor that the through hole of ring-shaped fire cover inside and outside wall and groove have obvious ladder height, makes to supplement auxiliary air from different spaces in its combustion process, avoids clashing, and makes fire inside ring-shaped fire cover (ring fire namely) Thorough combustion, improve efficiency of combustion.

Further, groove comprises the second groove that the first groove that the degree of depth is h1 and the degree of depth are h2, h1 < h2.Further increase supplements the spatial level of air, improves efficiency of combustion.

Further, h1 < (1/2) h2.Between first groove and the second groove, depth difference is apart from making auxiliary air supplementary result more desirable greatly.

Further, each first groove and two the second grooves form one group of annularly fire cover madial wall repeated arrangement.Repeat evenly laying the first groove and the second groove and make even flame, cook effective.

Further, the groove width of groove is 1.5-2mm.The width of groove is moderate, and the heat of burner is concentrated, and then ring fire Thorough combustion in promoting, flame is clear.

Further, the through described ring-shaped fire cover madial wall of groove slant, groove center line is α with the RADIAL angle through this groove center point, and 25 °≤α≤45 °, the angle between adjacent two groove center line is β, 7.5 °≤β≤8.5 °.Groove is that above-mentioned angular range is arranged, and can promote the Thorough combustion of flame inside ring-shaped fire cover further.

Further, 32 °≤α≤45 °.

Further, the exit position of through hole is higher than the position of groove.Outside design ring-shaped fire cover, fire supplements air from high spatial, and inside ring-shaped fire cover, fire supplements air from low spatial, realizes supplementing auxiliary air from different spaces in its combustion process, avoids conflict, and improves efficiency of combustion.

Further, the second through hole that through hole comprises the first through hole that aperture is d1, aperture is d2 and aperture are the third through-hole of d3, d1 < d2 < d3.Outside ring-shaped fire cover, design multiple aperture through hole, increase the level supplementing air, improve efficiency of combustion.

Further, distributor sidewall and bottom surface are provided with auxiliary air and supplement passage.Add the passage that auxiliary air enters, and then add the magnitude of recruitment of air, make burning more abundant.

The beneficial effects of the utility model are, by arranging through hole and the groove of supplementary air on ring-shaped fire cover inside and outside wall differing heights position, make to supplement auxiliary air from different spaces in its combustion process, avoid clashing, thus make fire inside ring-shaped fire cover (ring fire namely) Thorough combustion, improve efficiency of combustion.

Detailed description of the invention

The utility model scheme is better understood in order to make those skilled in the art person, below in conjunction with the accompanying drawing in the utility model embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.

With reference to shown in Fig. 1, Fig. 2 and Fig. 3, burner comprises burner 1, the distributor 2 be connected on burner 1, be arranged on the central flame cap 3 at distributor 2 center and be arranged on the ring-shaped fire cover 4 of distributor 2 outer shroud, burner 1, distributor 2 and ring-shaped fire cover 4 define a gas mixing chamber be communicated with, the lateral wall of ring-shaped fire cover 4 is circumferentially evenly laid with multiple through hole 5, the madial wall of ring-shaped fire cover 4 is circumferentially evenly laid with multiple groove 6, this groove 6 runs through the madial wall of ring-shaped fire cover 4, and the position of through hole 5 and the position of groove 6 exist obvious difference in height.

The position of through hole 5 is higher than the position of groove 6, and vice versa.

The groove width of groove 6 is 1.5-2mm, and the degree of depth comprising the first groove 61 and the second groove 62, first groove 61 is h1, and the degree of depth of the second groove 62 is that h2, h1 are less than h2, and in the present embodiment, the degree of depth of the first groove 61 is less than the degree of depth of 1/2nd second grooves 62.First groove 61 and two the second grooves 62 form one group, and many group grooves repeat to be evenly arranged on the madial wall of ring-shaped fire cover 4.
