The specific embodiment
Following with reference to description of drawings each embodiment of the present invention.
＜first embodiment 〉
Fig. 1 represents the smoke exhaust ventilator 1 in the first embodiment of the present invention.Smoke exhaust ventilator 1 have be used to catch by below the slim cover portion 80 of steam of producing of the cooking carried out, oil smoke etc., described cover portion 80 has the wainscot 81 of concavity up at inner face.Cover portion 80 is connected with Fan Box 82 near being positioned at the cover peristome 2 of substantial middle, and described Fan Box 82 is connected with discharge duct D.Fan Box 82 has fan drum 61 in inside, fan drum 61 has the fan 60 that produces air stream in inside, and described fan 60 is sirocco fans.The air entry 62 of fan 60 is configured in the cover peristome 2 of cover portion 80.Therefore, become negative pressure if fan 60 turns round then covers peristome 2, the air of wainscot 81 belows is inhaled into via cover peristome 2, and discharges to the outside via discharge duct D.That is, the empty gas stream flow channel that produces at fan 60 of cover peristome 2 is positioned at upstream one side of fan 60.
Have at cover peristome 2: with and wainscot 81 between do not produce the installing plate 50 that the mode in the gap that can become air flow circuit is installed; Discoid filter 10 with the hole that ventilated; The motor 20 that rotating shaft is connected with the center of the disk of filter 10 and filter 10 is rotated; For the motor installation 40 that motor 20 is installed on the installing plate 50; And be installed on the installing plate 50 and surround the oil content capturing means 30 of the outer peripheral edges of filter 10.Therefore, smoke exhaust ventilator 1 possesses filter 10 in rotating mode, the empty gas stream flow channel that described filter 10 produces at fan 60 is positioned at upstream one side of the fan 60 of described air stream, and has the hole that described air stream is passed through when figure from bottom to top.
In addition, cover portion 80 possesses control part 90, and described control part 90 is controlled the rotation of the motor 20 that makes filter 10 rotations and the rotation of fan 60.In the present embodiment, control part 90 is arranged in the cover portion 80, but is not limited to this, also can be arranged on arbitrary position of smoke exhaust ventilator 1, can also be arranged on the outside of smoke exhaust ventilator 1.Control part 90 so that the mode that fan 60 and motor 20 side by side rotate control.That is, control part 90 is controlled by this way: at least one when smoke exhaust ventilator 1 rotates the fan 60 that produces air stream in order to catch the oil smoke that produced by the cooking etc. makes motor 20 rotate constantly.In addition, what is called makes fan 60 or motor 20(filter 10) rotate and to refer to that specifically what is called does not make its rotation refer to outage to fan 60 or motor 20 energisings.
The air of wainscot 81 belows comprises the steam that produced by the cooking, oil smoke etc., if fan 60 running, then described air by on cover peristome 2, be that the hole of the filter 10 of empty gas stream flow channel that fan 60 produces upstream one side that is positioned at fan 60 attracts and by described hole.Filter 10 is configured to rotate by motor 20, if smoke exhaust ventilator 1 running, then motor 20 rotates filter 10 when fan 60 produces air stream.Smoke exhaust ventilator 1 rotates by making filter 10, will be included in airborne oil content and be captured on the oil content capturing means 30.The method that explanation is later on caught.
With compare by using existing fluting filter or HEPA filter etc. that refinements such as slit or mesh or overlapping multilayer are improved the measure that oil trap obtains efficient, this smoke exhaust ventilator 1 can have high oil trap with the little state of the pressure loss and obtain efficient.Namely, if the mesh by using refinement slits such as existing fluting filter or HEPA filter or overlapping multilayer improve oil trap and obtain efficient, then the ventilating part of filter can form complicated stream, thereby aeration resistance has the trend that increases, and under the situation of described smoke exhaust ventilator 1, because be that rotation by filter improves oil trap and obtains efficient, so do not need to form the stream of this complexity.Therefore, compare with existing filter, can under the state of keeping lower aeration resistance, obtain high oil trap and obtain efficient.In addition, reduced oil content and be attached on the filter and cause phenomenon of blocking, accordingly, can reduce the labour of the cleaning of filter self, prevented that the pressure loss from increasing along with use; In addition, because almost there is not oil content to adhere on the downstream part of the filter in air flow circuit, can provide a kind of smoke exhaust ventilator that alleviates the burden that the downstream part of filter is cleaned/cleaned significantly.
The kind of the fan of fan 60 is not particularly limited, and can be other fans such as aerofoil fan that produce air stream.Preferably, the high sirocco fan of static pressure that uses in the present embodiment.In addition, possess below the cover portion 80 and cover portion 80 is detachable and and cover portion 80 between have the gap and improve the cowling panel 70 of inhalation power.Though the smoke exhaust ventilator 1 in the present embodiment possesses cowling panel 70, the existence of cowling panel 70 is not particularly limited, and is not essential.Under the situation that does not have cowling panel or pull down under the situation of cowling panel, as shown in Figure 2, the user can directly see: as the wainscot 81 of the concavity up of the inner face of cover portion 80, oil content capturing means 30 not produce installing plate 50, the discoid filter 10 that the mode in gap installs with wainscot 81 and to be installed on the installing plate 50 and to arrange in the mode of the outer peripheral edges that surround filter 10.
The filter that Fig. 2 represents to control the rotation of motor 20 rotates gauge tap 91.As later explanation, the motor 20 that 90 pairs of control parts rotate filter 10 carries out various controls, but in addition, operates filter by the user and rotate gauge tap 91, and user oneself is the rotation of controlled filter device neatly.Filter rotates gauge tap 91 can begin, rotate and finish and action such as change velocity of rotation according to the rotation that motor 20 is carried out in operator's operation.In addition, as the attended operation of filter 10, can carry out only making motor 20 rotate the operation that automatically stops after the stipulated time.
In addition, in the present embodiment, though filter 10 forms by forming discoid thin plate, be not limited thereto, for example filter also can be tubular.In the case, the filter of tubular rotates tube by the rotating shaft that the central shaft at tube connects motor, and has the hole that ventilated in the side of tube.Air stream is constituted as from the inboard, lateral of the side of tube and passes through.In addition, the oil content capturing means is configured to surround the side of tube.Tube can also can be placed vertically by traverse.Under the situation of tube traverse, the oil content capturing means possesses peristome open below the suction air and the peristome of opening in order to make air flow to fan one side.Under the situation that tube is placed vertically, not at the bottom surface of tube opening, in addition, the oil content capturing means is configured to surround the whole side of filter to filter because the side from tube sucks air stream.Because can have easy structure and slim smoke exhaust ventilator can be provided, so be preferably formed the such filter that is formed by discoid thin plate of present embodiment.
In addition, in the present embodiment, the part of surface except the hole in the both sides of filter 10 do not have thrust or concavo-convex, but smooth and smooth even surface, but being not limited to this, also can be the thrust that has lug etc. as common fluting filter with slit (hole).If filter possesses level and smooth surface as present embodiment, then the aeration resistance of the air on filter stream further reduces, and then the rotary resistance of filter also reduces, and is therefore, just enough as long as the motor that filter is rotated has a little moment of torsion.In addition, owing to there is not jut such as lug at filter, therefore can provide a kind of little smoke exhaust ventilator of noise that cuts air.In addition, accordingly, be easy to make filter to rotate at high speed.In addition, because nearly all oil content all is filtered the surface of device and catches, the phenomenon of catching oil content in the side in the hole of filter does not almost have, therefore further reduce because of the oil phenomenon of blocking in the hole of filter, in addition because there is not the jut of lug etc., so the cleaning/cleaning of filter self becomes easy.
Fig. 3 and Fig. 4 represent the filter 10 of smoke exhaust ventilator 1 and periphery thereof (below, be called filter unit).Filter unit 3 possesses: be installed in the installing plate 50 on the cover peristome 2; Discoid filter 10 with the hole that ventilated; The motor 20 that rotating shaft is connected with the center of the disk of filter 10 and filter 10 is rotated; For the motor installation 40 that motor 20 is installed on the installing plate 50; And be installed on the installing plate 50 and be arranged to surround filter 10 around oil content capturing means 30.
Installing plate 50 is the roughly foursquare flat boards that possess circular installing plate peristome 51 at central portion.In the present embodiment, have curvature and crooked upward around the flat board, but be not limited to this, as long as have the structure on the cover peristome 2 that is installed in wainscot 81.The installation of installing plate 50 and cover peristome 2 does not form gap etc., and air stream does not pass through the mounting portion.Therefore, installing plate peristome 51 becomes unique part of the circulation of air that makes fan 60 generations, and installing plate peristome 51 becomes the empty gas stream flow channel that fan 60 produces.
When motor 20 is seen rotating shaft in the drawings from the top downwards (from one side direction upstream, downstream, one side of air stream) run through the hole 41 of motor installation 40, and described motor 20 is fixed on the motor installation 40.The rotating shaft 21 of motor 20 becomes the center of circular installing plate peristome 51 when overlooking.
The position that filter 10 is seen in the front be installing plate 50 lower surfaces below be upstream one side of air stream.Therefore, oil content capturing means 30 is installed on the installing plate 50 in the mode of the outer peripheral edges that surround filter 10.The distance of the outer peripheral edges of filter 10 and the inwall of oil content capturing means 30 need be greater than 0 for both are not contacted, but then is preferably as much as possible little for oil-proof branch.In the present embodiment, for about 2.5mm.Oil content capturing means 30 is provided with oil conservator 31 in the lower end.The oil content that flies with the collision of upstream one side surface and the bullet of filter 10 is run into the inwall of oil content capturing means 30, and oil conservator 31 is the places that store this oil content.
In addition, the height of smoke exhaust ventilator 1 comprises the height of cover portion 80 and the height of Fan Box 82, but the height of Fan Box 82 is roughly stipulated by the height of fan 60, the height of cover portion 80 is by the height of filter unit 3 concave depth (highly) the sum regulation with the wainscot 81 that is used for catching the air that comprises oil content etc., the height of described filter unit 3 namely from the upper end of motor 20 to the height of the lower end of oil content capturing means 30.In order to catch the air needs concave depth (highly) to a certain degree that comprises oil content etc., the height that therefore reduces filter unit 3 is for the whole height that reduces smoke exhaust ventilator 1 and slim smoke exhaust ventilator is provided is important.In the present embodiment, filter unit 3 is because filter 10 forms by forming discoid thin plate, so thin and be preferred.
Fig. 5 and Fig. 6 are the figure that catches the effect of the oil content of following air stream in the explanation smoke exhaust ventilator 1.Fig. 5 represents the effect that smoke exhaust ventilator 1 all air flow.Hot-air A rises to smoke exhaust ventilator 1 with the steam that is produced by the cooking of carrying out below smoke exhaust ventilator 1, oil smoke etc.If smoke exhaust ventilator 1 entry into service and fan 60 begin to rotate, then fan 60 from bottom to top direction when figure produces air stream.So, rise near cowling panel 70 air and between cowling panel 70 and wainscot 81, be inhaled into, be inhaled into the air entry 62 of the fan 60 in the fan drum 61 then via the hole 11 of filter 10.Then, discharge from Fan Box 82 to discharge duct D.
The revolution of the time per unit of filter 10 also depends on the open state in the hole of filter, but at least more than or equal to 230rpm(Rotation Per Minute: revolutions per minute) get final product.When filter 10 higher speed ground rotate, the air that contacts with described surface is pulled on the surface of filter 10 (part that does not have hole 11) because of frictional force, and this motion also can under the effect of the viscosity of air near transfer of air, accordingly, produce the motion of air at the near surface of filter 10, and because filter 10 is rotated motion, so the motion of air becomes the swirl shape centered by rotating shaft.
The two sides that this gyrate air movement is created in filter 10 is the lower surface of filter 10 and upper surface on the two, in other words, is created in filter 10 on the surface of the surface of upstream one side of air stream A and downstream one side on the two.In the present embodiment, the air stream A that fan 60 takes place passes through the hole 11 of filter 10 from bottom to top and flows when figure, so in the downstream of filter 10 side, the motion of gyrate air takes place to open and towards the helical form air-flow of the outer peripheral edges of filter 10 from the towing of filter 10, and utilizes fan 60 and attract to open from air entry 62.On the other hand, in the upstream of fan 10 side, gyrate air movement forms presses to the surface of filter 10 and is accompanied by towards the high air layer of density of the swirl shape stream of the outer peripheral edges of filter 10.
Fig. 6 is illustrated in the effect of the air stream on the filter unit 3.The oil content OP1 that produces in the cooking etc. flows with air stream A and the near surface of upstream one side of arrival filter 10.The oil content OP2 that arrives the near surface of upstream one side is the swirl shape stream towards outer peripheral edges of the high air layer of density owing to a part (oil content that particle diameter is little), and another part (oil content that particle diameter is big) collides with the surface (part that does not have hole 11) of upstream one side of filter 10, thereby splashes to the outer peripheral edges direction of filter 10.Its result is hunted down as oil content OP3 being equipped on the oil content capturing means 30 of the outer peripheral edges that surround discoid filter 10, and reclaims as oily OL in oil conservator 31.
Become very tiny atomic oil content and pass through the hole of filter 10 with air stream A, but a part wherein can and reclaim with the inwall collision of filter 10 downstreams one side of extension 52 or oil content capturing means 30.The part of final unrenewable oil content is attached on the fan 60 that is positioned at downstream one side more, the discharge duct D etc., become size for the major part of the atomic oil content of the degree in the hole by filter 10 then directly along with air current A via discharge duct D discharged to outdoor.Therefore, almost do not have oil content to adhere on the trip of the filter 10 of the smoke exhaust ventilator 1 of present embodiment of the present invention in the air flow circuit part, can alleviate the burden of the fan 60 of cleaning/filter rinsed 10 downstream parts and discharge duct D etc. significantly.
When colliding on the surface of the upstream of oil content and filter one side (part that does not have hole 11), the major part of oil content flies to the outer peripheral edges direction bullet of filter, and a part is attached on the described surface.If the velocity of rotation of filter is accelerated, the oil content that then temporarily is attached to filter surfaces flies by action of centrifugal force and to the outer peripheral edges direction.Its result, smoke exhaust ventilator of the present invention adheres to and residual oil content minimizing at filter, can reduce the labour of the cleaning of filter self accordingly.
Accordingly, side by side rotates by making filter 10 and fan 60, can be used in the noise that the motor 20 of filter 10 rotations produces, the wind noise that is caused by the rotation of filter etc. becomes the degree that the user can not note.Namely, under the situation that filter when fan stops to rotate, because there is not the noise by the fan generation, so the noise that motor produces, the wind noise that is caused by the rotation of filter etc. are obviously, but by filter and fan are rotated together, therefore the wind noises that the noise that utilizes fan to produce swallows up the noise that produced by motor, produce because of the rotation of filter etc. can become the degree that makes that the user can not note.In addition, be the running of smoke exhaust ventilator 1 and the rotation of filter 10 by the rotation of constantly side by side carrying out fan 60 at least one, can reduce the adhesion amount of the oil content on the filter 10, can prevent oil content deadlocked on filter surfaces.
Fig. 7 is that expression is at the key diagram of the variation example of the control method of the fan 60 of present embodiment and motor 20.Use the ON(solid line) time that expression is rotated fan 60 and motor 20, use the OFF(dotted line) represent not make time of its rotation.In the variation example 0 of the rotation of filter, control part 90 is such as mentioned above, so that the mode that fan 60 and motor 20 side by side rotate is controlled.In this variation example, any one motor 20(filter 10 in fan 60 rotates) rotate.Can be any one rotation in fan 60 rotates, its rotation time be not particularly limited.
In addition, Fig. 7 represents existing smoke exhaust ventilator as existing example.Existing example will be between not on-stream period of smoke exhaust ventilator because be (smoke exhaust ventilator stop in) is to remove the oil content that is attached to during fan rotates on the filter being during fan does not rotate between the smoke exhaust ventilator on-stream period, so after ON became OFF, the function of removing oil content became ON at fan.Thereby, the present invention so that fan 60 and the mode that motor 20 rotates simultaneously to control on this point consideration method with existing example different fully.
In the variation example 1 of the rotation of filter, control part 90 makes in the rotation of fan 60 twice ON rotate across OFF, during being rotation dichotomous.In this variation example, be divided into during twice the rotation, but be not limited to this, also can be with ON and OFF repeated several times in the rotation of fan 60.Accordingly, the noise that can when reducing the adhesion amount of oil content on filter motor be produced, the wind noise that is produced by the rotation of filter etc. are suppressed to Min..
In the variation example 2 of the rotation of filter, whenever control part 90 all makes motor 20(filter 10 in the rotation of fan 60) rotate.That is, control part 90 is so that the moment that the rotation of the moment that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the rotation of the identical moment and fan 60 to be finished and motor 20 finishes is the mode in the identical moment controls.In addition, control part also can be so that the moment that the rotation of the moment that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the rotation of the identical moment or motor 60 to be finished and motor 20 finishes be the mode in the identical moment controls.Accordingly, by the beginning, end etc. as the rotation of the rotation of the motor 20 of the power source of filter 10 action and fan 60, the smoke exhaust ventilator that can provide a kind of user can not note the generating noise of motor 20 side by side are provided.
Certainly, also can be as changing example 5, control part 90 is so that the moment that the rotation of the moment that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the rotation of the identical moment and fan 60 to be finished and motor 20 finishes is the mode in the identical moment controls, and in the rotation of fan 60 rotation of motor 20 interrupted.
In the variation example 3 of the rotation of filter, control part 90 is so that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the identical moment and the mode that finishes the rotation of motor 20 after the rotation of fan 60 finishes after through the stipulated time controls.That is, in the rotation of fan 60 with to change example 2 identical, but after the rotation of fan 60 finishes, motor 20(filter 10) still be rotated further a period of time.Accordingly, after can finishing in the rotation of fan 60 oil content that is attached on the filter 10 is flown out, filter 10 can be maintained the state of cleaning, its result, can provide a kind of reduces oil content adhering on filter 10/deadlocked, the smoke exhaust ventilator that alleviates the burden of cleaning/filter rinsed 10.In addition, be attached on the filter 10 if finish the back oil content in the smoke exhaust ventilator running, then deadlocked and blocking filter 10 or generation imbalance of oil content can produce meaningless noise, but just can prevent this noise like this when next entry into service.In addition, though control part 90 makes motor rotate the stipulated time that how long can be defined as being fit to after the rotation of fan 60 finishes, but for example also can be defined as the long time under the long situation in fan strong duration of runs, and be defined as the short time in the weak duration of runs under the long situation.
Certainly, also can be such as changing shown in the example 6, control part 90 is so that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the mode in the identical moment controls, and control in the mode that finishes the rotation of motor 20 after finishing in the rotation of fan 60 after through the stipulated time, and in the rotation of fan 60, the rotation of motor 20 is interrupted.
In the variation example 4 of the rotation of filter, control part 90 is controlled by this way: the rotation of motor 20 is begun and temporary transient in the rotation of fan 60 in have no progeny and begin again to rotate, after the rotation of fan 60 finishes, finish the rotation of motor 20 then after through the stipulated time.Accordingly, make filter 10 high-speed rotation before being about to begin by the rotation at fan 60, can in using last time, remain in oil content on the filter and blow and fly, and can utilize the filter that does not have the cleaning of stopping up to carry out catching of oil content.In addition, in the case, because fan 60 is to postpone a little just to begin to rotate after smoke exhaust ventilator running beginning, so before the rotation of fan 60 was about to begin, filter 10 rotated in short time.Like this, control part 90 can be so that the moment that the rotation of the moment that the moment that the rotation of fan 60 begins and moment that the rotation of motor 20 begins are the rotation of the different moment and fan 60 to be finished and motor 20 finishes be the mode in the different moment controls.Accordingly, rotate independently by making fan and filter, can control more flexibly.
Certainly, also can be as changing example 7, control part 90 begin with the rotation that before fan 60 rotates, makes motor 20 and temporary transient in the rotation of fan 60 in have no progeny and begin again to rotate, making the moment that the rotation of fan 60 finishes and the moment that the rotation of motor 20 finishes then is that the mode in the identical moment is controlled.
In the variation example 8 and 9 of the rotation of filter, control part 90 is so that the revolution of the time per unit of fan 60 changes and make motor 20(filter 10 according to the rotating speed of fan 60) the mode of rotation speed change control.The change in rotational speed rate of fan 60 can be identical as changing example 8 with the change in rotational speed rate of motor 20, can be different as changing example 9 also.Accordingly, can apply stronger centrifugal force under the situation of a lot of oil contents and make oil content fly out to prevent the obstruction of filter 10 from the filter 10 fast adhering to, reduce the adhesion amount of oil content and prevent that the rotating speed of smoke exhaust ventilator from making filter 10 be rotated with the high speed more than or equal to required speed when slow.In addition, also can be as changing example 8, control part 90 makes the rotating speed changed in stages of fan 60 and motor 20.Accordingly, can control with the rotating speed that such user a little less than the persistent erection differentiates easily.In addition, the weak rotating speed that waits of persistent erection is relative rotating speed, and and do not mean that absolute rotating speed.
Usually, when producing the oil smoke cooking how, select the fast rotating speed of fan to use.Therefore, the more fast more many trend of oil smoke that then produces of rotating speed that has fan.That is, the more fast amount that then is attached to the oil content on the filter 10 of the rotating speed of fan is more many and more quickly stop up.Therefore, increase and decrease the revolution of the time per unit of filter 10 by the rotating speed according to fan, can adhere at oil content makes it apply stronger centrifugal force with high-speed rotation more under many situations, make oil content fly out to prevent the obstruction of filter 10 fast from filter 10, and can when the rotating speed of fan is slow, prevent that filter 10 from rotating with the high speed more than or equal to required speed.
The aperture (mm) of the filter in the table 1 expression present embodiment and the relation of rotating speed (rpm) and capture rate.Be 0.75mm, 1mm, these four types of measurements of carrying out capture rate of 1.5mm, 2mm with the aperture.Rotating speed at filter is under the situation of 0rpm, and which kind of aperture no matter all is lower than capture rate best in the existing filter namely 70%, and capture rate is not high in the filter that does not rotate as can be known.
On the other hand, if filter is rotated with 1000rpm, even the filter of the aperture 2mm that then capture rate is minimum, capture rate also is 77%, surpasses the capture rate of existing best filter.In addition, along with diminishing, the aperture is that it is 80%, 86%, 88% that 1.5mm, 1mm, 0.75mm, capture rate further uprise gradually.In addition, if the rotating speed of filter is arranged to 1500rpm, then along with diminishing, the aperture is that it is 84%, 86%, 91%, 93% that 2mm, 1.5mm, 1mm, 0.75mm, capture rate uprise gradually.In addition, if the rotating speed of filter is arranged to 2000rpm, then be 2mm, 1.5mm, 1mm along with the aperture diminishes, capture rate becomes 88%, 90%, 90%.Thereby, while smoke exhaust ventilator of the present invention rotates filter by making fan produce air stream, catch and be included in airborne oil content.In addition, if increase filter time per unit revolution or reduce the aperture, then can obtain high oil trap and obtain efficient.
[table 1]
Fig. 8 is at the capture rate of the filter of the smoke exhaust ventilator of the fluting filter that is used for obtaining present embodiment and using current version and the test structure figure that oil content uses in the test of the relation that components downstream such as fan, pipeline are adhered to.The different this point of capture rate and confirm oil content attachment state on components downstream, the as described below test according to the capture rate difference in filter for the aperture difference of the filter that utilizes present embodiment.
Method of testing is as follows.The 800mm place arranges the smoke exhaust ventilator that possesses filter of the present invention etc. above the heating plate of Controllable Temperature.Place stainless steel cylinder at the heating plate that is heated to 245 ℃, from pump to described stainless steel cylinder to drip oil and with the 8g/ minute water that drips in 2.5g/ minute.Testing time is 10 minutes.In addition, the rotating speed of filter is 1500rpm.
The result of this test of table 2 expression.According to this test, then the smoke exhaust ventilator in current version namely uses in the smoke exhaust ventilator of fluting filter, catch 50% oil content in filter, and 23% oil content is attached on the components downstream.Remaining 27% oil content is discharged to the outside with air.On the other hand, namely possess in the smoke exhaust ventilator of filter of aperture 2.0mm at the smoke exhaust ventilator of present embodiment, catch 83% oil content at filter, adhere to 7% oil content in components downstream.In addition, in the smoke exhaust ventilator of the filter that possesses aperture 1.5mm, catch 83% oil content at filter, adhere to 2% oil content in components downstream.In addition, in the smoke exhaust ventilator of the filter that possesses aperture 1.0mm, catch 87% oil at filter, surprisingly on components downstream, do not adhere to oil content.
According to described test, compare with the capture rate of the smoke exhaust ventilator of existing type, in the smoke exhaust ventilator of present embodiment, the capture rate on filter obviously brings up to 83% or higher.Its result can significantly be suppressed at oil content the adhering on components downstream that spends time when cleaning/cleaning waits.If it also just is 70% that consideration has capture rate the best of known smoke exhaust ventilator now, then the smoke exhaust ventilator of the present invention that uses in this test we can say that smoke exhaust ventilator of the present invention has high capture rate no matter how varying aperture all has the capture rate more than or equal to 83%.Therefore, almost there is not oil content to adhere on the downstream part of the filter of smoke exhaust ventilator of the present invention in air flow circuit, so can alleviate the burden of cleaning/filter rinsed downstream part significantly.
[table 2]
＜second embodiment 〉
Omit with the explanation that first embodiment repeats, difference only is described.Present embodiment is compared with first embodiment, and just control part is different with the control method of motor 20 at fan 60, so describe as control part with control part 90A.
Control part 90A controls in the mode that the rank in the rotating speed minimum of fan 60 is not rotated motor 20.That is, under the situation of the rotating speed that changes fan 60 as above-mentioned variation example 8 and 9, control part 90A controls in the mode that hour motor 20 is not rotated at the rotating speed of fan 60.As the main noise source that produces from smoke exhaust ventilator, the fan that produces air discharged stream, wind noise etc. are arranged.That is because under the slow-speed of revolution such as weak running of fan 60 when running integral body noise little, so follow the sound of rotation of filter 10 and motor 20 remarkable.Therefore, when weak running, also there is the situation that filter is not rotated.Accordingly, under the tangible situation of the sound of the rotation of following filter, do not rotate by making filter, quiet smoke exhaust ventilator can be provided.
On the contrary, fan 60 in or under the situation about turning round under the strong higher rotation speed that waits, because the rotation sound of filter 10 is swallowed up by the noise that fan 60 sends, so control part 90A makes filter 10 rotations.In addition, when fan 60 weak runnings, because the general oil smoke that produces by the cooking is also few, the total amount that is attached to the oil content on the filter 10 is also few, so do not need to prevent by rotation the obstruction of filter 10.
In addition, control part 90A can rotate under the situations about finishing, makes motor 20(filter 10 when the rotation of fan 60 finishes to rotate the back in 60 in fan with the ranks of the revolution minimum of the time per unit of fan 60) mode of rotating controls.Accordingly, by after the running end of smoke exhaust ventilator, in the time of for example near the user leaves the kitchen range top, filter 10 is rotated, the oil content that adheres to is flown out, make oil content fly out to prevent the obstruction of filter fast from filter 10, can reduce the adhesion amount of oil content and provide for the user who leaves smoke exhaust ventilator and Yan Buhui notices the smoke exhaust ventilator of noise.
In addition, minimum rank in the rotating speed of the rank of the revolution minimum of the time per unit of so-called fan 60 fan 60 that also can be hypothesis use in when cooking.Namely in the smoke exhaust ventilator of the normal ventilatory that is equipped with indoor integral body, general, the rotating speed minimum during normal ventilation running, the rotating speed of fan 60 for example according to weak, in, the order of strong running becomes big.But, can not suppose and in the cooking, use normal ventilation.Therefore, in this case, can adopt weak running as the rank of the revolution minimum of the time per unit of fan 60.
In addition, the present invention is not limited to the embodiment of example, can implement according to the structure of the scope of the every described content that does not break away from appended claim scope.
