Definitions
- the invention relates to a fume extraction device, in particular a fume extraction device for extracting fumes from a cooking area.
- a trigger housing is provided with a suction through which the contaminated air, in particular fumes or vapors that arise during cooking, can be sucked into the hood and removed from there.
- a filter element for cleaning the sucked air is usually provided at the suction opening.
- a disadvantage with these known extractor devices is that, in particular in the case of an extractor device which is connected to the environment, a so-called exhaust hood, ambient air can enter the room via the suction opening in which the extractor device is operated.
- blocking elements such as a back pressure flap in the air duct to the weather-side outlet of the extractor device, that is to provide the outlet to the environment.
- These locking elements are difficult to access due to the installation in the duct between the extractor device and the weather side and can therefore be difficult to repair or replace.
- Such blocking elements are used for example in wall boxes, as described in DE 84 032 48 U1.
- a device for extracting and supplying air for a cooking place is further described.
- This device should be variable and, in particular, the flow conditions should be adapted to different cooking situations over the hob.
- a device is used in which a relative to the hotplate pivotable plate is connected to an exhaust duct.
- the plate preferably includes a plurality of hinged flaps for covering a filter provided in the plate.
- the plate can be brought into a vertical orientation and is connected to an exhaust duct, which is transported the extracted air down to a fan provided below the cooking place. By the air is discharged from the plate down, air flow is due to the below a cooking place usually provided devices for operating the Cooking place elaborate.
- the object of the present invention is thus to provide a fume extraction device in which the ventilation guide in the extractor device can be influenced in a simple manner with a simple construction of the extractor device.
- a vapor extraction device with a blower and a trigger housing, which has at least at one part of the trigger housing at least one suction opening for sucking air, to which at least one movable closure element is provided, which closes the suction at least temporarily.
- the extractor device is characterized in that the suction opening is vertically aligned and the trigger housing has an air outlet at its rear or upper side.
- the air guide can already be influenced at the suction opening of the extractor device. If the extractor device is not used, for example, the suction can be closed. The penetration of air from the environment but also the ingress of contaminants in the trigger housing can be prevented. In contrast to the operating state of the extractor device, in which a separation of impurities can be effected by a blower provided in the extractor device, it can happen when the fan of the extractor device is switched off that the impurities pass through an intended filter element or at least enter it.
- the vacuum set by the blower in the service train is not present, it can lead to an obstruction of the openings provided in a filter element by the impurities that have entered. This can be prevented by the closure elements provided according to the invention or the closure element provided. By the closure element is arranged to be movable, this can at least partially release the suction if necessary.
- the suction opening is designed vertically, this can be provided on the one hand on a trigger housing, which has a vertical orientation and thus are provided in a simple manner behind or next to a cooking position can.
- the setting of the movable closure elements the air flow to the suction opening can be efficiently influenced, since the rising from a cooking fumes moves substantially upwards and the closure elements can protrude in this direction of movement.
- the air duct of the trigger device can be simplified as a whole.
- the arrangement of the air outlet at the top or the back of the trigger housing in particular, a deflection of the sucked air from the direction in which it enters the trigger housing, only a small extent required.
- the design of the extractor device when providing an air outlet on the back or the top of the trigger housing according to the given environmental conditions can be selected.
- the sucked by a provided in the trigger housing fan air is discharged to the environment.
- the closure element can be arranged displaceably or pivotably on the trigger housing.
- at least one of the closure elements is a flap.
- Closure element is in particular that the movement mechanism is designed simpler. Since the closure element is arranged at the suction opening and thus in the region of the inlet contaminated air in the trigger housing, the use of a simple movement mechanism for the closure element or (e) is advantageous because it is less prone. In addition, a pivoting mechanism can be actuated more easily, since a mechanical lever may be sufficient to allow pivoting of the closure element. By pivoting the at least one closure element, a targeted adjustment of the actually available for the suction surface of the suction opening can also be defined. For example, the closure element with respect to the plane of the suction opening in which it is pivotally mounted, are pivoted by 45 °.
