Abstract
The utility model relates to an induced draft nozzle for a fluid diaphragm smoke suction/exhaust cooker, which can completely exhaust lampblack or mixed gases generated in a pot or hazard gases produced by fuel gas burning during cooking. The induced draft nozzle comprises a fluid diaphragm soot suction/exhaust device, wherein a negative-pressure gas chamber in the fluid diaphragm soot suction/exhaust device is formed by a plurality of induced draft nozzles; an induced draft chamber in each induced draft nozzle is trumpet-shaped, a suction port in each induced draft nozzle is strip-shaped, circular or oval, and a suction nozzle in each induced draft nozzle is shaped like a rectangular, circular or oval cylinder; and the suction nozzles are communicated through a negative-pressure gas suction pipe and further communicated with an extract opening of an air pump. The utility model has the advantages that the negative-pressure suction force at the suction ports in the negative-pressure gas chamber is effectively improved, and the suction pressure flow rate is also increased, so that lampblack and mixed gases in the pot and hazard gases generated by a gas cooker are instantly exhausted through the suction ports of the negative-pressure gas chamber and a negative-pressure exhaust pipe in sequence, thereby eliminating lampblack, oil and hazard gases during cooking.
Description
Technical field
The utility model relate to a kind of can be when cooking cooking, be used for the air draught mouth that fluid diaphragm is inhaled smoke exhaust range with what the pernicious gas that oil smoke or mist and fuel gas buring produced that is produced in the pot was discharged fully, the air draught mouth is made the field.
Background technology
The patent No. 00134172.3, title " a kind of smoke dust sucking exhauster with fluid diaphragm ", diffusingsurface one side of this device in the smoke contamination source is provided with the fluid blow-off outlet that pressure is arranged of parallel this diffusingsurface, this blow-off outlet connects pressure fluid source, be provided with the fluid intake that negative pressure is arranged of parallel this diffusingsurface with the in addition side of its position symmetry, this suction inlet connects depression generator; The fluid that blows out from this blow-off outlet enters suction inlet and forms fluid diaphragm, this fluid diaphragm with pollution sources flue dust diffusion space surround shroud in from blow-off outlet to the smoke dust duct between the suction inlet.Its weak point: a plurality of negative pressure inlet scoop is communicated with negative pressure cabin, during pumping with exhaust blower, because the relatively big negative pressure cabin in middle space that directly acts on, and negative pressure cabin has a plurality of strip holes all around, can't form strong band suction between this strip hole and the negative pressure cabin, therefore the negative pressure that acts on the negative pressure inlet scoop is relatively very little, air-flow is very low, in the pernicious gas negative suction storehouse that is produced when the flue gas in the time of can't will cooking cooking in moment, mist and gas-fired, the leaking outside of the pernicious gas that is produced when causing flue gas, mist and gas-fired.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of air draught mouth that fluid diaphragm is inhaled smoke exhaust range that is used for that can form big suction, high flow rate in the negative pressure inlet scoop.
Design: in order to realize above-mentioned purpose of design.That the air draught storehouse of a plurality of air draught mouths in the negative pressure gas storehouse in the smoke dust sucking exhauster with fluid diaphragm is is horn-like, suction inlet is stripy or the design of the rectangular circular or oval tubular of round mouth shape or oval mouthful shape, suction nozzle, is major technique feature of the present utility model.The purpose of doing like this is: by the diameter of the negative pressure suction nozzle suction inlet less than the air draught storehouse, therefore according to siphon principle, when pumping with exhaust blower, the negative pressure and the flow velocity that produce in the suction nozzle place are far longer than the air draught storehouse, stream band at a high speed can be discharged suction nozzle at will pace up and down oil smoke around the suction inlet of air draught storehouse or mixed gas flow and pernicious gas that gas-fired produces of moment in by negative pressure cabin negative suction blast pipe, thus the cooking that realizes cooking smokeless, do not have oily, a no pernicious gas.
Technical scheme: be used for the air draught mouth that fluid diaphragm is inhaled smoke exhaust range, it comprises smoke dust sucking exhauster with fluid diaphragm, negative pressure gas storehouse in the described smoke dust sucking exhauster with fluid diaphragm is to be made of a plurality of air draught mouths, that air draught storehouse in the air draught mouth is is horn-like, suction inlet is stripy or round mouth or oval mouthful shape, the rectangular circular or oval tubular of suction nozzle, and a plurality of suction nozzle is communicated with by negative pressure suction tube and is communicated with the pumping with exhaust blower mouth.
The utility model is compared with background technology, improved the negative-pressure sucking at suction inlet place in the negative pressure gas storehouse effectively, improved suction baric flow speed, the suction inlet of the pernicious gas that can be produced when oil smoke, mist and gas range burning in pot in moment by negative pressure gas storehouse enters in the negative pressure exhaust pipe discharges, and the cooking that realizes cooking is smokeless, do not have oil, no pernicious gas.

The specific embodiment
Embodiment 1: with reference to accompanying drawing 1～3.Be used for fluid diaphragm and inhale the air draught mouth of smoke exhaust range, it comprises smoke dust sucking exhauster with fluid diaphragm, negative pressure gas storehouse in the described smoke dust sucking exhauster with fluid diaphragm is to be made of a plurality of air draught mouths, that air draught storehouse 2 in the air draught mouth is is horn-like, suction inlet 1 is stripy or round mouth or oval mouthful shape, suction nozzle 3 rectangular circular or oval tubulars, and a plurality of suction nozzle 3 is communicated with and is communicated with the pumping with exhaust blower mouth by negative pressure suction tube 8.
Described suction nozzle 3 internal diameters are less than air draught storehouse 2 outlet internal diameters, or the internal diameter of suction nozzle 3 is the outlet internal diameter in air draught storehouse 2, that is to say, can not want the suction nozzle 3 of independent air draught storehouse part.
Embodiment 2: with reference to accompanying drawing 3.On the basis of embodiment 1, gas cover type integrated environment-friendly stove, it comprises smoke dust sucking exhauster with fluid diaphragm and kitchen range, described smoke dust sucking exhauster with fluid diaphragm is that 9 stacks of malleation compression ring 5 and negative pressure gas storehouse constitute and malleation compression ring 5 is positioned on the negative pressure gas storehouse 9, negative pressure gas storehouse is to be made of a plurality of air draught mouths, air draught storehouse 2 in the air draught mouth is horn-like, suction inlet 1 is stripy or round mouth or oval mouthful shape, suction nozzle 3 rectangular circular or oval tubulars, and a plurality of suction nozzles 3 are communicated with and are communicated with the pumping with exhaust blower mouth by negative inspiratory pressure pipeline 8, malleation compression ring 5 is communicated with fan outlet by air supply pipe 6, and the inboard hoop of malleation compression ring 5 has fluid issuing 7 or has the helical form fluid issuing.
