Abstract

The utility model discloses a burner refractory cover comprising a refractory cover seat and a fuel gas channel under the seat. The utility model is characterized in that a fire hole connecting to such fuel gas channel is opened on a fire hole ring inside the refractory cover. Direction of the fire hole can form a certain included angle Alpha with radius direction of the fire hole ring. Moreover, the fire hole inclines from the bottom to the top and forms a certain included angle Beta with plane direction. With included angle Alpha and Beta, the fuel gas from fire hole can burn completely and the firepower can be more concentrative on cooker of gas burner. The utility model can fulfill complete burning, high burning rate and conform to environmental protection requirements.

Description

A kind of burner fire lid

[technical field]

The utility model relates to a kind of burner, refers in particular to the fire lid on the burner.

[background technology]

Existing household gas utensils, the fire hole direction that its burner fire covers is on the radial direction of fire hole circle, and fire hole is parallel with the in-plane of fire hole circle, the burning of the combustion gas of coming out from fire hole can not align the cooker on the gas-cooker like this, and the burning of combustion gas is also insufficient, has reduced the combustion utilization efficiency of combustion gas, and the waste gas that burning is produced is more, cause the pollution of environment many, so be necessary current burner fire lid is improved.

[utility model content]

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can make the burner fire lid that fuel gas buring is abundant, combustion rate is high and meet the environmental protection demand.

The utility model is to adopt following technical proposals to realize:

A kind of burner fire lid, include fiery cage, below described fiery cage, be provided with blast tube, it is characterized in that: have the fire hole that communicates with this blast tube on the fire hole circle of described fiery cage inboard, the radial direction of the direction of described fire hole and this fire hole circle forms certain included angle α; After from bottom to top tilting, described fire hole also forms certain included angle β with in-plane.

Aforesaid burner fire lid is characterized in that: the angle α that the radial direction of described fire hole and this fire hole circle forms is 0～60 °.

Aforesaid burner fire lid is characterized in that: the angle β that forms between described fire hole and the in-plane is 0～60 °.

Aforesaid burner fire lid is characterized in that: the fire hole on described fire hole circle has two rows, and every row's fire hole is identical with the angle α that the radial direction of this fire hole circle forms; The angle β that forms between every row's fire hole and the in-plane is also identical.

Compared with prior art, the utlity model has following advantage: because the center of fire hole of the present utility model and fire hole circle is certain included angle α, horizontal plane with the fire hole circle after fire hole is inclined upwardly simultaneously also is certain included angle β, can make the burning of the combustion gas of coming out from fire hole more abundant like this, firepower aligns cooker on the gas-cooker in the concentrated area more, so the utility model can make the burner fire lid that fuel gas buring is abundant, combustion rate is high and meet the environmental protection demand.

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:

[specific embodiment]

The utility model is a kind of burner fire lid, it includes fiery cage 1, below fiery cage 1, be provided with blast tube 4, on the fire hole circle 2 of described fiery cage 1 inboard, have the fire hole 3 that communicates with this blast tube 2, for making the fuel gas buring that comes out from fire hole 3 abundant, minimizing is to the pollution of environment, the direction of fire hole 3 and the radial direction of this fire hole circle 2 are arranged to certain included angle α (showing as Fig. 3), fire hole 3 are from bottom to top tilted afterwards also form certain included angle β (showing) as Fig. 4 with in-plane.Can make firepower behind the fuel gas buring concentrate and just align cooker on the burning kitchen range like this, can improve the combustion utilization efficiency of combustion gas.

The common angle α that the radial direction of fire hole 3 and this fire hole circle 2 is formed is arranged to 0～60 °, simultaneously the angle β that forms between fire hole 3 and the in-plane is arranged to 0～60 °.

In the embodiment shown in Fig. 1-4, the fire hole 3 on fire hole circle 2 has two rows, and every row's fire hole 3 is identical with the angle α that the radial direction of this fire hole circle 2 forms; Simultaneously the angle β that forms between every row's fire hole 3 and the in-plane is also identical.
