Description

A kind of lower smoke evacuation burner hearth using hearth outer wall setting smoke discharging pipe

Technical field

The utility model relates to commercial gas to have accessory technical field, and in particular to a kind of to utilize hearth outer wall setting smoke evacuation The lower smoke evacuation burner hearth of pipeline.

Background technique

Currently, one is use refractory brick to repair with refractory cement aggregate there are mainly two types of the burner hearths that commercial gas-fired stove uses It builds, another kind is cast by metal material.Wherein there are mainly two types of modes for the exhaust emissions of casting burner hearth, and one is logical Burner hearth setting smoke outlet discharge suitable for reading is crossed, another kind is discharged in burner hearth bottom surface setting smoke outlet, is arranged in burner hearth bottom surface and is discharged fume The burner hearth of mouthful discharge, in order to make burner hearth internal-combustion fire smoke gases be evenly distributed, it usually needs multiple smoke outlets are set in bottom Different parts, require another outer burner hearth in this way and be used cooperatively with it, by outer burner hearth by the multiple smoke outlets of internal furnace The flue gas of discharge is collected, and concentrates row in the connecting pipe of a smoke outlet and outside by outer burner hearth bottom is arranged in It puts, such bottom exhaust fume stove basin structure has that burning situation is more closed, flue gas is in burner hearth internal stops time longer feature, because This its be conducive to improve burner hearth interior environment temperature, and then to the release of fuel gas calorie, be absorbed and utilized with benefit, while it is this Burner hearth is discharged fume because flue gas emission path is longer in bottom, flue gas curvilinear flow in addition, thus can preferably reduce noise generation and Transmitting can bring benefit for design production low-noise environment-protection energy-saving gas cooker；But at present this bottom smoke evacuation burner hearth there is also A fly in the ointment, show must by it is inside and outside it is double-deck burner hearth is mating can be only achieved using effect, so increase burner hearth Production material cost, at the same also increase production installation and debugging workload, for its be arranged smoke discharging pipe with connect and can occupy More gas-cooker inner space, tail gas heat quantity also can biggish increase gas-cooker internal temperature rise, accordingly can to gas-cooker inside electricity Device electronic component generates damaging influence.

Utility model content

In view of the deficiencies of the prior art, the utility model discloses a kind of lower rows using hearth outer wall setting smoke discharging pipe Cigarette burner hearth, the smoke discharging pipe for carrying tail gas via furnace basin pass through edge on curvilinear path to burner hearth by furnace basin bottom part The smoke outlet of setting discharges, and gas cooker inner space occupancy is effectively reduced, and can reduce kitchen range internal temperature rise, in turn Benefit is brought for gas cooker inside electric appliance and electronic component safety and longtime running.

The utility model is achieved by the following technical programs:

A kind of lower smoke evacuation burner hearth using hearth outer wall setting smoke discharging pipe, it is characterised in that: including single layer burner hearth, smoke evacuation Pipeline, gas inlet and offgas outlet；The sidewall outer of the single layer burner hearth regional area is provided with the smoke discharging pipe, described Cross section that smoke discharging pipe outer wall is pasted with and the single layer hearth outer wall collectively form cross section in oval or rectangle, vertical The L-shaped smoke discharging pipe in section, inward-facing upper opening forms offgas outlet, the single layer burner hearth under the smoke discharging pipe Bottom is equipped with the gas inlet, and the offgas outlet is connected with the gas inlet.

Preferably, offgas outlet opens on the single layer burner hearth along end face above the smoke discharging pipe.

Preferably, the cross section that the smoke discharging pipe outer wall is pasted with is U-shaped.

The utility model has the following beneficial effects:

Smoke discharging pipe is placed directly within burner outer wall and becomes an entirety, it can be achieved that by interior furnace basin by the utility model All beneficial effects that may be implemented with two layers of furnace basin of outer furnace basin, while transport and installation cost and working hour can be reduced, it can make Burner hearth overall structure is stronger reliable, using one-stor(e)y furnace basin setting smoke discharging pipe, can be by the tail gas generated in furnace basin by furnace basin Smoke exhaust pipe road junction collects, is delivered on burner hearth by smoke discharging pipe and is flowed out along end face smoke outlet below, can effectively reduce gas-cooker Have inner space to occupy, and kitchen range internal temperature rise can be reduced, so for electric appliance inside gas cooker and electronic component safety and Longtime running brings benefit, and smoke discharging pipe vertical section is L-shaped to keep flow of flue gas track curved, can preferably reduce noise biography Out, beneficial to design production low-noise environment-protection energy-saving product.
