Extractor device

The present invention relates to a kind of extractor device, especially for the extractor device of suction kitchen range top smog.

Suction housing has suction opeing on the extractor device, can be by it with contaminated air, and smog that produces when particularly cooking or steam suction suction housing are also discharged therefrom.Have generally speaking on the suction opeing and be used to purify the filtration members that sucks air.The shortcoming of this known extractor device aspect is that particularly on the so-called exhaust hood of the extractor device that is connected with the external world, surrounding air can enter in the room of extractor device work by suction opeing.Therefore leading to the windward side outlet of extractor device, just leading in the air guiding device of extraneous outlet and need to have for example block piece of anti-backflow cover plate.These block pieces are owing to be installed in the air channel between extractor device and the windward side and be difficult to contact, and therefore also are difficult to repairing or replacing.This block piece for example uses in box body of wall, being introduced in DE 84 032 48U1.

WO 2004/090425A2 has introduced a kind of device that is used for kitchen range top suction and carries air in addition.This device it is said that the mobility status on variable and the kitchen range top particularly can match with the different situations of cooking.Use a kind of device for this reason, wherein can be connected with exhausting duct with respect to the plate of kitchen range top swing.This plate comprises the removable cover of best a plurality of hinged installations, the filter that is used for having in the overlay.Plate can be vertically-oriented and be connected with exhausting duct, and exhausting duct is transported to air blast below the kitchen range top downwards with the air of extracting out.By the air slave plate is discharged downwards, air guide is because the device that is had generally speaking below the kitchen range top makes the operation of the kitchen range top become complicated.

Therefore purpose of the present invention is, a kind of extractor device is provided, and wherein under extractor device situation simple in structure, can influence the air guide of extractor device in a simple manner.

This purpose is achieved by a kind of extractor device according to the present invention, this extractor device has air blast and suction housing, it has the suction opeing that at least one is used for suction air at least a portion suction housing, the removable closure member of sealing suction opeing when having at least one on the suction opeing and having at least.This extractor device is characterised in that, the vertically-oriented and suction housing of suction opeing has air outlet at its back side or upside.

By closure member is set on suction opeing, user or installation personnel also are easy to contact this closure member after extractor device is installed.On this external foundation extractor device of the present invention, on the suction opeing of extractor device, just can influence air guide.If do not use extractor device, for example suction opeing can be closed.Therefore can stop the air in the environment to also have dirt to enter in the suction housing.The duty that can produce the extractor device that separates with dirt by the air blast that is had in the extractor device is opposite, under the air blast situation that disconnects extractor device, pollutant can pass the filtration members that is had or enter this filtration members at least.Because there is not the negative pressure that produces by air blast under the duty, so can stop up the opening in the filtration members owing to entering of pollutant.By according to these closure members of the present invention or this closure member of being had, can prevent it.Be provided with movingly by closure member, can discharge suction opeing to small part when wherein needing.

Vertically-oriented by suction opeing, can have this suction opeing on the suction housing on the one hand, vertically-oriented and therefore this suction housing can be arranged on kitchen range top back or next door according to plain mode.When this external suction opeing was so directed, the adjustment of removable closure member can effectively influence the air guide to suction opeing, because the smog that rises from the kitchen range top moves upward basically and closure member can stretch into this direction of motion.Upside or back side tool by suction housing are provided with air outlet, can simplify the air guide of aspirator in addition generally.Be arranged on the upside or the back side of suction housing by air outlet, only need on not half, make the air of suction enter the directional steering of suction housing from it.In addition, the upside or the back side of suction housing have air outlet, can select the configuration of extractor device according to given external condition.For example can will be discharged into the external world by the air that is located at the air blast suction in the suction housing.But also can make the air that is aspirated return the indoor of extractor device work.Because no matter be generally speaking suction housing face or on all be not used in the device that makes kitchen range top work, so can simply air be imported the air blast of these directions and extractor device can be arranged on suction opeing near.

Closure member is removable or be arranged on the suction housing swingably.A kind of preferred embodiment in, at least one in the closure member is removable cover.Use the removable cover that to swing with respect to the closure member of removable setting, under the situation about more simply constituting particularly in motion.Because closure member is arranged on the air that also therefore is arranged on pollution on the suction opeing and enters in the zone of suction housing, so being used for closure member, simple motion has advantage, because this motion is not fragile.The also easier operation of this external tilting mechanism is because a mechanical lever is enough to make closure member to be swung when needing.By swinging described at least one closure member, can define specific aim in addition and adjust actual suction opeing area for the suction use.For example, the closure member suction opeing plane rocking that can be bearing in swingably with respect to this closure member is 45 °.If the angle of selecting is littler, so owing to effective exhausting area is reduced in the gap that forms between closure member and the suction opeing plane.Another advantage that use can be swung closure member is that this closure member only needs to be fixed on the suction housing by two fixing points.These fixing points that for example are on closure member swinging axle or the rotating shaft end can trigger according to plain mode.This point can trigger by machinery or electricity carries out.

Preferably have the suction opeing of a plurality of clearance types on the suction housing and have closure member on each suction opeing.By this embodiment, can reduce the size of single closure member on the one hand and simplify its operability thus.On the other hand, even closure member is in this embodiment when swinging with respect to suction opeing, also only slightly from suction face projection forward.On vertically-oriented basically extractor device, can guarantee that in this embodiment suction opeing opens, for example remove and need not to move the object that is in the extractor device front as cooking apparatus and from the moving radius of closure member.

A plurality of suction opeings can form the suction face of the static line interruption of only passing through closure member of suction housing jointly.In this manner, air can be sucked in the suction housing by large tracts of land.Closure member is sheet or removable cover preferably, and it is set parallel to each other and below free end points to.This set can seal suction opeing on the one hand under the not state of activation of extractor device.On the other hand, under the state of activation that closure member is preferably swung, not only discharge suction opeing, exactly, form the conducting element of the air guide suction opeing that will aspirate by the closure member of swing by these closure members.Particularly have a plurality of preferably recline mutually and the embodiment of the clearance type suction opeing of orientation parallel to each other in, can form the guiding clearance of suction air between the closure member of two adjacent swings.

According to a kind of embodiment, main directed vertically extension of suction housing and the front of suction housing has at least one suction opeing.Main orientation be meant pack into or the installation site on the maximum sized direction of suction housing.Preferred especially suction housing is vertically-oriented, but also can from vertically to slight inclination, particularly turn forward.Front as suction housing is meant the face of vertical suction housing towards the kitchen range top that needs suction air or other positions in this case.
