Description
Technical field
The present invention relates to utilize pot or band the cooking of cooking appliances such as shallow pan the time gas that contains oil smoke (both having contained water vapour in this gas) that produces if gas stove also contains discharging waste gas be discharged into the employed fan of smoke exhaust of outdoor use by discharge duct.
Background technology
Between the kitchen or the cooking, utilize pot or band the various cooking appliances cooking such as shallow pan the time, need the waste gas that fuel gas buring is generated or contain oil smoke and the steam of peculiar smell etc. discharges as emission gases.Contain the gas of such oil smoke if immediately it is not discharged into outdoorly, both formed the anaerobic condition that efficiency of combustion is reduced and the people is not impacted, simultaneously again because of oil smoke to polluting in the room.Therefore, usually, utilize the gas that ventilation fan will contain these oil smoke to discharge, perhaps the smoke exhaust suction of the top by being configured in cooking appliance and to utilize pressure fan to be discharged to from discharge duct outdoor.
Especially, if will utilize the method for exhausting of smoke exhaust and the method for exhausting that uses ventilation fan to compare, owing to utilize smoke exhaust can guide the gas that contains oil smoke effectively, thereby in so-called system kitchen, use.And, if smoke exhaust is arranged on the place that produces near the gas that contains oil smoke, owing to can reliably the gas that contains oil smoke be discharged, thereby a lot of as its advantage of method for exhausting.
Yet in the existing method for exhausting that uses such smoke exhaust, following two problems are still unresolved; First problem is to produce noise at work; Second problem is at machine intimate and becomes the processing of the oil smoke of pollution sources near the outer wall of the peristome of discharge duct.
At first, when the 1st noise problem inquired into, can think: general smoke exhaust is for having sizable size with all surrounding around the cooking appliance, owing to be used to discharge from the discharge duct of the gas that comprises oil smoke of suction here and only be limited in the size that diameter is about the discharge duct 220 of 15cm, thereby pressure fan must be made the main equipment that is easy to produce noise, in addition, in the local time that touching ventilating duct various, the gas that contains oil smoke all produces noise.
In addition, utilizing smoke exhaust ventilator to aspirate under the situation of the gas that contains oil smoke, when having complicated barrier in the passage of the gas that is containing oil smoke, not only therefore increased draw resistance, reduced pumping efficiency, but also become the reason that produces above-mentioned noise.In more detail, owing to must be directed to discharge duct on the wall or ceiling is first-class and exhaust openings is arranged on outdoor, thereby, the bore of discharge duct is compared very little as mentioned above with the aperture area of smoke exhaust, for the gas that will contain oil smoke aspirates without barrier and discharges and must put in a lot of time and effort to the very little discharge duct of above-mentioned bore.
Especially, in the kitchen that is provided with the feeder different with exhaust apparatus, if a combustion gas, with having 400 meters
3Though/hour about the exhaust apparatus of ability enough, discharge oil smoke, necessarily require 500 meters
3/ hour about ability.But, thereby, must have maximum 700 meters if will make the exhaust apparatus that to discharge oil smoke fully because the other kitchen that feeder is set separately etc. seldom
3/ hour about ability.If will utilize the big like this exhaust apparatus of ability to carry out exhaust, in no case can avoid the generation of above-mentioned noise from the discharge duct of diameter about for 15cm.
Therefore, as the big and little device of noise of capacity, though can consider to adopt so-called Xi Luoke (シ ロ Star コ) fan, but general Sirocco fan is if comprise its shell, its volume is also quite big, as if this fan being arranged in the little smoke exhaust of volume or under the situation on the other parts, then must doing great change to whole project organizations in smoke exhaust or system kitchen.Yet, comprising the design alteration of the volumetric change of smoke exhaust etc., realistic situation almost is impossible in limited kitchen space.Its result is even the high Sirocco fan of ability also have to maybe can not adopt in the former state use.
Therefore, the present inventor had both given full play to the advantage of using the method for exhausting of smoke exhaust for how to realize, drop to the noise that produces extremely low again, the exhaust apparatus that promptly can solve the 1st problem has carried out all research, as a result, made in Japan and speciallyyed permit proposed invention in No. 2609280 communique.
This invention that has proposed is as follows:
" a kind of exhaust apparatus is used for discharging to the discharge duct side from the gas that contains oil smoke of the discharges such as cooking device of setting between the kitchen and the cooking and with it by smoke exhaust 11 suctions, it is characterized in that:
This exhaust apparatus is made of ventilated box and air exhauster; This ventilated box is arranged in the smoke exhaust or its top and Ying Yuqi below are communicated with, and is arranged in the storage case that accommodates discharge duct and is connected on the discharge duct, and this air exhauster folding and unfolding is in this ventilated box; Simultaneously
Ventilated box has and is connected with this discharge duct side and towards the connecting box of the minor diameter of this discharge duct, and by the next door with inclined plane that the approximate centre towards discharge duct tilts is set, thereby has exhaust side towards the discharge duct inclination and be a pair of ventilating duct of minor diameter in the substantial middle of this ventilated box part;
And, air exhauster is by the drive motors with the driving shaft that passes the next door and protrude in each ventilating duct one side and be installed on each driving shaft respectively and the Sirocco fan that is contained in each ventilating duct constitutes, simultaneously, thus making the blade lean of each Sirocco fan make it is minor diameter from the suction hole side to the drive motors side.”
The exhaust apparatus that the inventor has proposed in this speciallys permit No. 2609280 communique, though wherein can solve above-mentioned the 1st problem, through after discover, for the 2nd oil smoke problem, may be still inadequate.
Secondly, the 2nd problem of relevant oil smoke inquired into.In general smoke exhaust, as shown in Figure 1, in this ventilator cowling main body 210, set in advance filter 230, utilize this filter 230 collect institute directly suction oil smoke and make its liquefaction and form oil droplet.Yet, it is impossible utilizing the filter 230 that is arranged in this ventilator cowling main body 210 to collect whole oil smoke, residual oil smoke is positioned at the general range hood fan suction in the downstream of this filter 230, thereby pollution constitutes the blade of this range hood fan etc.
The general range hood fan that is positioned at the inboard of filter 230 is difficult to clean, and the cleaning that constitutes the inner vanes of this range hood fan almost is impossible.Therefore, when the oil droplet on being attached to each blade is piled up gradually, become the reason of the afunction of range hood fan probably.
Therefore, in TOHKEMY 2000-104969 communique, the scheme of " improving the multi blade fan fan drum of the simple structure of oily collection performance " has been proposed.This fan drum as shown in figure 12, " the contact area of wind is not only limited to the inner face of shell 1; and expand the inside and outside two sides that is arranged on the aeroscopic plate 4 in the shell 1 to ", " can shell main part and left side plate do not processed, provide the collection efficiency that has improved lubricant component, the fan drum that can not stop up with the cheap cost of simple structure." (seeing 0021 section record of above-mentioned communique)
Yet, as mentioned above, can think, wind (gas that comprises oil smoke) not only with the inner face of shell 1, and be arranged on shell 1 in wind deflector 4 contact be the reason of generation noise; Thereby, can think to solve the 1st above-mentioned noise problem.
Certainly, though put down in writing 0011 section of above-mentioned communique " ingress edge 4 ' of aeroscopic plate 4 is made inclined side, toothed edge etc. so that the distinguished and admirable fashionable collision time that staggers; thereby prevent that the total length of clashing into ingress edge 4a ' because of wind simultaneously from producing noise ", even but only have the effect that prevents to produce noise in the porch, this also is the part of a long wind deflector 4, it is contemplated that almost to reach the Expected Results that prevents noise.Because the gas that comprises oil smoke is flow through on the surface on plane of aeroscopic plate 4, thereby this technology is difficult to imagination and can carries out the collection or the seizure of oil smoke fully, and it can eliminate the 2nd problem about oil smoke fully to be difficult to imagination.
In addition, speciallyying permit No. 3009649 in Japan publishes in the communique, having proposed with " providing a kind of can improve the collection efficiency of lubricant component and can prevent the smoke exhaust that lubricant component goes out to pipeline one effluent under the condition that the pressure loss is risen " is purpose, the scheme of as shown in figure 13 " smoke exhaust ".
In this existing smoke exhaust shown in Figure 13, to achieve these goals, the way that adopts is " inner face one side at the fan drum that accommodates the fan that is equipped in the pressure fan in the ventilator cowling is made male and fomale(M﹠F) " (claim 1), especially record as claimed in claim 4, " the concavo-convex of aforementioned body part forms mutually continuously, thereby the flow direction formation of the wind (gas that contains oil smoke) that forms because of the fan rotation is intersected.”
So, be sucked into the gas that contains oil smoke in the fan drum then to above-mentioned concavo-convex the bump, therefore, though it be unclear that collect oil smoke effect how, but as above-mentioned existing example shown in Figure 12, can think to produce noise because of wind clashes into male and fomale(M﹠F).
Therefore, how the present inventor had just both given full play to the advantage of the method for exhausting that has used smoke exhaust, the noise that produces can be dropped to not only extremely low and but also the method that can carry out the recovery of oil smoke effectively carried out all discussions repeatedly, the result has finished the present invention.
Summary of the invention
Promptly, the object of the present invention is to provide a kind of range hood fan 100, it can collect the oil smoke that utilizes the general filter be positioned at upstream side not collect certainly fully, and, even when collecting this oil smoke operation, can not produce noise when just containing the gas flow of oil smoke yet.
The present invention makes in view of above situation, and at first, employing will describe the device that the present invention's the 1st scheme adopts by employed label in the explanation of preferred forms described later.
The range hood fan 100 of the present invention's the 1st scheme, it utilizes ventilator cowling main body 210 to collect the gas that contains oil smoke of emerging from cooking devices 300 such as the pot cooked or pans, and is discharged to from discharge duct 220 at the gas that will contain this oil smoke and uses the outdoor smoke exhaust 200 and to be contained in the ventilator cowling main body 210; It is characterized in that:
This range hood fan 100 is made of the Abgasabsaugung mouth 15 of housing body 10, fan electromotor 30 and housing body 10; Wherein, the part of this housing body 10 is connected with discharge duct 220, is formed with exhaust passage 14 in inside; This fan electromotor 30 is supported on the next door 12 in this housing body 10, on its rotating shaft 31 fan 32 is housed; This Abgasabsaugung mouth 15 is formed on the part of ventilator cowling main body 210 inner openings; And,
Lower inner in housing body 10 disposes the dictyosome formation that 40 utilizations of the 1st filter 40, the 1 filters can see through above-mentioned gas, has at the direction of rotation extension of fan 32 and many articles the 1st grooves 41 of its end 14 split sheds in the exhaust passage; And, dispose the 2nd filter 50, the 2 filters 50 in the inboard of the 1st filter 40 and utilize the dictyosome that can see through above-mentioned gas to form, have article the 2nd groove 51 that manys of bigger and its end 14 split sheds in the exhaust passage than above-mentioned the 1st groove 41;
Utilize fan 32 to flow along each the 2nd groove 51 and the 1st groove 41 by making, thereby utilize the 1st filter 40 and 50 liquefaction of the 2nd filter and collect the interior oil smoke of above-mentioned gas from the above-mentioned gas that comprises oil smoke of Abgasabsaugung mouth 15 suctions.
Promptly, this range hood fan 100 is as Fig. 8-shown in Figure 10, to utilize on the inner surface of the 1st filter 40 of dictyosome formation and the lower inner that the 2nd filter 50 is configured in this housing body 10, the 1st filter 40 and the 2nd filter 50 have the 1st groove 41 and filter 230 respectively.The 1st groove 41 of groove 51 to the 1 filters 40 sides of range hood fan 100 especially of the present invention by making the 2nd filter 50 sides is bigger, as shown in figure 10, each the 1st groove 41 is entered in the 2nd groove 51 fully, thereby form the part that the 1st filter 40 and the 2nd filter 50 are in contact with one another.
Has the as above range hood fan 100 of structure, when its fan electromotor 30 rotations, be installed in fan 32 rotations on its rotating shaft 31, then begin to contain from Abgasabsaugung 15 suctions on the housing body 10 that is formed on this range hood fan 100 gas of oil smoke by the ventilator cowling main body 210 of smoke exhaust 200.At this moment, contain the part of the oil smoke in the gas of oil smoke because the filters 230 that are set in the ventilator cowling main body 210 collect for the first time, though thereby when reaching each Abgasabsaugung mouth 15 seldom, but still can not have fully.
As mentioned above, rotation by fan 32 from the gas that contains oil smoke of each Abgasabsaugung mouth 15 suction shown in the hollow arrow Fig. 9, in the exhaust passage 14 though flow through in the housing body 10, but the major part of the gas that contains oil smoke at this moment is shown in the hollow arrow on the left side among Fig. 9, enter into inside from the diagram left side of the 1st filter 40 and the 2nd filter 50, the remaining gas of oil smoke that contains flows along the surface (for the face of fan 32 1 sides) of the 2nd filter 50.Certainly because each the 1st filter 40 and the 2nd filter 50 for example form by the wire netting body, thereby the gas that contains oil smoke that flows by each mesh from the inboard of the 1st filter 40 and the 2nd filter 50 laterally fully by or therewith inversely by ground.

The specific embodiment
Below, with regard to the above-mentioned every invention of range hood fan 100 explanations of most preferred embodiment shown in the drawings, in fact the range hood fan 100 of this most preferred embodiment comprises all above-mentioned every inventions.
Fig. 1 represent with in range hood fan 100 of the present invention is housed smoke exhaust 200 with the situation in the kitchen of installing near the state of ceiling 410, in this kitchen, utilization is heated with gas stove or the cooking appliances 300 such as the electromagnetism cooking 310 pairs of pots of machine or pan near the state setting of wall 420, and the seizure that comprises the gas of the oil smoke that is produced by each cooking appliance 300 promotes to discharge to the outside from discharge duct to the suction of oil-containing flue gas body and with it by the range hood fans of the present invention 100 that utilization is arranged in the smoke exhaust 200.
When the gas that contains oil smoke with 200 pairs of this smoke exhausts aspirates, though be to utilize the filters 230 be arranged in the ventilator cowling main body 210 to remove oil smoke in the gas that contains oil smoke, but this not removing can be removed oil smoke 100% ground, and remaining oil smoke then is sucked in the range hood fan 100 of the present invention.
The inside of the housing body 10 of range hood fan 100 is to be equipped with fan electromotor and fan 32 in the airtight conditions, the upper end of housing body 10 is to be used for the pipeline connecting portion 13 of connection opening at outdoor discharge duct 220, with the inboard of this pipeline connecting portion as outlet 11.In addition, have the Abgasabsaugung mouth 15 that is used to aspirate the gas that contains oil smoke that ventilator cowling main body 210 catches in the left and right sides of this housing body 10.In addition, in the outlet 11 of this housing body 10, be provided with the plate washer 16 that is used to cut off the atmosphere that enters by discharge duct 220.
In addition, below this housing body 10 as Fig. 1 and shown in Figure 11, but be provided with the switch cover 20 of free switch, this switch cover 20 utilizes hinge 22 to be installed on the housing body 10 as shown in Figure 9.In addition, this switch cover 20 utilizes to be arranged on the fixed screw 23 of hinge 22 opposite sides and fixes with respect to housing body 10.
Have, the middle position in housing body 10 inside is provided with next door 12 as shown in Figure 8 again, and the both sides in this next door 12 become the exhaust passage 14 that is communicated with discharge 11 and next door 12 respectively.In addition, fan electromotor 30 is being supported in this next door 12 as shown in Figure 8, and the fan 32 that is fixed on the rotating shaft 31 of this fan electromotor 30 is not positioned at 12 both sides, next door respectively revolvably.
In addition, each fan 32 is what is called " Sirocco fan " that a plurality of blade 32a of prolongation are set on rotating shaft 31 directions of fan electromotor 30, and, make each blade 32a along with it being tilted laterally towards each Abgasabsaugung mouth 15.By such formation fan 32, thus the noise that has improved the suction force of this fan 32 and can prevent to produce along with the conveying of the gas that contains oil smoke.
Near the 1st filter 40 of switch cover 20 as shown in figure 10, be formed with many articles the 1st grooves 41, become the 1st filter passage 42 between these the 1st grooves 41 and the switch cover 20.Each the 1st groove 41 is the elongated slot that extends in the direction of rotation of fan 32 as shown in Figure 9, thereby is difficult to the gas flow that contains oil smoke is formed resistance, also increases the contact area to the gas that contains oil smoke simultaneously.In addition, the two ends 41a of each the 1st groove 41 as shown in Figure 9, with respect to formed exhaust passage 14 openings in the housing body 10 so that the gas that non-resistance ground carries out containing oil smoke imports the 1st filter passage 42 or from wherein derivation.
Directly 14 the 2nd filter 50 also forms along many articles the 2nd grooves 51 that contain the gas flow direction of oil smoke as shown in figure 10 towards the exhaust passage, but the 2nd groove 51 is all done greatlyyer than the 1st groove 41 of the 1st filter 40 1 sides.In the present embodiment, 2 article of the 1st groove 41 making the 1st filter 40 1 sides can enter into 1 article of the 2nd degree in the groove 51.Certainly, between the 2nd groove 51 of adjacency, as shown in figure 10, the both ends 51a that forms the 2nd filter passage 52, the 2 filters 50 as shown in Figure 9, opening is in exhaust passage 14.The result of above structure is, should the 2nd filter 50 also same with above-mentioned the 1st filter, owing to having reduced containing the resistance of soot gas along the 2nd groove 51 that contains the gas flow direction of oil smoke, and, become smooth owing to both ends 51a makes the importing of the gas that contains oil smoke and discharge.
Because the 1st filter 40 and the 2nd filter 50 boths have mesh, it is self-evident that the gas between that contains oil smoke can move freely.This is because suppose that the gas that contains oil smoke produces turbulent flow in housing body 10, because this turbulent flow freely moves by mesh, in fact can not become stable turbulent flow.
And,, contain oil smoke in the gas of oil smoke and just collected and liquefy by the 1st filter 40 or the 2nd filter 50 because such gas that contains oil smoke contact by mesh or with the surface of the 1st filter 40 and the 2nd filter 50.The oil smoke that has liquefied then flow within the switch cover 20 through the 1st filter 40 and the 2nd filter 50, and stores in the oil container 21 that is arranged on herein.
Yet, the range hood fan 100 of this most preferred embodiment as shown in Figure 9, the gas that contains oil smoke at first contacts with the 1st filter 40 and the 2nd filter 50 or the part of the exhaust passage 14 passed through is compared narrower with the part of the exhaust passage 14 of the rear end side that is positioned at the 1st filter 40 and the 2nd filter 50.Therefore, the gas pressure that contains oil smoke in the part near the outlet 11 of housing body 10 reduces, thereby makes oil smoke wherein be easy to liquefaction, and the oil smoke that has liquefied can be caught by the 1st filter 40 and the 2nd filter 50 more reliably.With respect to this, because both ends 41a, 51a exhaust passage 14, that be in Fig. 9 left side partly narrow down, in whole the 1st filter passages 42 that enter into the 1st filter 40 that cause the gas that utilizes each fan 32 to send to contain oil smoke and the 2nd filter passage 52 of the 2nd filter 50.
