Abstract
The utility model relates to a new smoke exhausting fan which closes a gas stove (a petroleum liquefied gas stove) and a cooker and exhausts oil smoke with a ventilation device, and the utility model adopts a hexahedron to close the gas stove and the cooker. The top surface of the smoke exhausting fan which closes the gas stove is an inversion funnel-shaped structure with small upper part and large lower part. The upper end of the top surface is provided with a fan, the front face of the hexahedron is closed by intangible air curtain, the intangible air curtain is generated by an air curtain generator comprising a transverse flow fan, and the front face can be mechanically closed by a movable transparent plate. The smoke exhausting fan which closes the gas stove has the advantages of simple structure, high practicality, and favorable oil smoke exhausting effect. The smoke exhausting fan which closes the gas stove can be used for various civil kitchen gas stoves, being a new oil smoke exhausting fan.
Description
The utility model relates to a kind of cooking apparatus.
At present, all kinds of smoke exhausts (the title smoke exhaust ventilator that has) that civilian kitchen gas range (oil liquefied gas kitchen range) user has been bought on market all be mounted in gas range top 750～1000 millimeter, and gas range and cooker are in open state fully.Though above-mentioned smoke exhaust can be discharged a part of kitchen fume and combustion product gases, about the about 6～8m3/min of air quantity, noise is generally about 70～72dB, exists following shortcoming and problem, mainly is:
(1) because smoke exhaust is far away apart from the coal gas kitchen range top, the not enough suction of blast strength is not enough, oil smoke, water vapour, flue gas were not overflowing before induced-draft fan in a large number, mist extractor up hill and dale, thereby still have a large portion oil smoke, particularly the pollutant of burning generation, water vapour etc. spread and contaminated environment in kitchen and room.(2) noise is higher, and for the residential houses, 70～72dB noise that existing smoke exhaust produces in the kitchen is higher, goes down for a long time and can produce adverse effect to health.
Therefore, solve the above-mentioned two problems of existing smoke exhaust, purify kitchen and living environment, the protection people ' s health is a comparatively urgent problem.
The purpose of this utility model is the design that proposes a kind of oil soot exhaustor, purpose is that existing oil extraction machine is carried out substantial improvements, promptly, change existing smoke exhaust is in open state away from gas range and gas range situation, take measures the gas range complete closed is discharged oil smoke more up hill and dale.Above-mentioned enclosure method should guarantee that cooking is easy to operate, and noise should be lower than existing smoke exhaust.
The utility model is can not solve thoroughly that gas range burning enters problem such as pollutant and cooker discharging oil smoke steam and the higher problem of noise and a kind of utility model induced-draft fan of proposing at kitchen gas range (oil liquefied gas kitchen range, as follows) with smoke exhaust.
Operation principle of the present utility model and structure are shown in Fig. 1.With a hexahedron 6 ［ smooth as kitchen range top face, also can save one side (bottom surface) becomes pentahedron ］ gas appliance all is closed together with cooking utensils (pot, kettle, cook with strockle etc.).Wherein end face generally is not a plane, but a up-small and down-big upside down funnel shape by if the works of the collection oil smoke that constitutes in individual facet works or curved-surface structure thing.Near the top of end face or its, a ventilation blower mist extractor (available cross flow fan or centrifugal fan) is installed.The performance of this ventilation blower should guarantee all oil smoke suctions in the obturator are discharged.
In with gas appliance, cooker complete closed, requirement must not influence normal cooking operation, guarantees that cooking is easy to operate.This is a critical problem.
The utility model proposes two or more feasible design for satisfying above-mentioned requirements.
A. the front of one of six faces of obturator (face that the operator faces), except that reserving one little enclosed construction thing 10 and leave the air vent 9 in the bottom, most without the mechanical close of any structure thing, but adopt invisible " air curtain "---air-flow by one deck smooth flow constitutes---to seal.Its principle is as follows: " air curtain " generator 11 is to be made of a motor-operated crossflow fan.This crossflow fan can be exported the uniform air flow of flat pattern, sees arrow among Fig. 1, flows to the obturator inside top always, is driven by motor 4 through top blower fan 3(again), and air duct 2,1 is discharged.Choose air stream outlet direction, air-flow thickness according to the crossflow fan performance and just can form water white invisible " air curtain " together.Make sealing surface with " air curtain " and can make oil smoke can not cross and overflow, because oil smoke is not once to run into " air curtain " be that to rebound be exactly to be involved in " air curtain " to discharge via the top.Above-mentioned principle is experiment confirm.So " air curtain " can play the effect of sealing surface.On the other hand, " air curtain " is invisible, can not influence the cooking operation.When cooking is operated, when operator's hand is crossed " air curtain ", have no obstacle, only can feel that the invisible and gentle air-flow that closes of one deck exists, never influence operation guarantees easy to operate.
B. movably works " machinery " sealing is adopted in the front of one of six of obturator faces.For example adopted among the embodiment can push-and-pull be moved in groove 5,73 blocks of transparent materials make plates 8, every block of plate has the shifting chute of oneself, 3 grooves are parallel.Like this can mobile at any time transparent panel and reserve enough operating spaces in when operation.In case of necessity even preceding full impregnated isotropic disk face can be taken out.
C. " air curtain " formula and the dual-purpose enclosed construction of " machinery " formula.See embodiment Fig. 1.Front at sealing surface is equipped with " air curtain " generator 11 and transparent panel 9 movably simultaneously, like this can be dual-purpose.With " machinery " formula enclosed construction, when being arranged, electricity do not use " air curtain " formula structure when having electricity.
D. except that the front, about two sides also can adopt in above-mentioned two kinds of methods one or both and use.But the motor number increases like this, and inconvenience is so only recommend three kinds of A, B, C.
Adopt the present invention will significantly improve the quality of air environment in kitchen and room, the steam oil smoke that the gas range burning can be produced etc. is discharged more up hill and dale.Its filth-discharging effect and the effect that purifies air will improve several times than existing smoke exhaust.The present invention simultaneously also can significantly reduce noise, and wherein semi-enclosed induced-draft fan can reduce noise 15～18dB; The totally enclosed type smoke exhaust can reduce about noise 10～20dB.
By above-mentioned effect as can be known, the present invention has the social benefit of more significantly improving environment, improvement pollution, protection people ' s health.
From economic aspect, market potential of the present invention is very big, even estimate by the most conservative market demand, the whole nation is about more than 600,000, and every calculates the output value with 200～300 yuan, and the gross output value is given about 1.2～1.8 hundred million yuan of meter.
The extent of spreading amd application: civilian kitchen gas range (oil liquefied gas kitchen range) user.
