Definitions

the invention relates to an extractor hood or the like.
a hood box which comprises an extraction chamber having an air inlet and an exhaust air outlet opening into an exhaust air connection piece, connected via a grease separator-equipped air passage to the extraction chamber, the grease separator of the air passage having a cleaning device with a spray nozzle-side spray chamber Spraying and a collecting channel for collecting and draining cleaning liquid is assigned.
Extractor hoods are available in a wide variety of designs, with the separators intended for dedusting and degreasing the exhaust air being arranged directly in the air inlet area of the hood box, which means that the cleaning options for these grease separators in the hood area are limited to unsatisfactory downstream flushing with cleaning fluid and thorough cleaning and removal the separator inserts and their washing outside the hoods.
hood boxes have so far been attached to a wall as umbrella-like individual hoods above a hotplate or the like.Mist source, there is only one air inlet on one hood box side, the rigid spray nozzles supplied by a fixed supply line require large amounts of cleaning fluid and therefore extensive installations and, last but not least, the cleaning liquid collecting in the collecting channel of the hood box must be disposed of via a wall-mounted pipeline.
These hoods are therefore relatively complex, can usually only be produced and installed as single pieces in an uneconomical manner and are also not suitable for installation in a ceiling cladding, as they are used in kitchens, in particular commercial kitchens.
the invention is therefore based on the object to remedy these defects and to provide an extractor hood of the type described which can be produced and installed efficiently and which, with a good deduction effect, is distinguished by its low-maintenance operation with the best self-cleaning effect.
the hood box can be prefabricated into a rectangular unit in plan, that the exhaust air chamber extends in a ring around the central suction chamber and that the air passage is composed of flow openings arranged all around, that the suction chamber has a cover plate on the bottom, the outer edge of which delimits a circumferential slot duct which forms the air inlet, that a central spraying device is provided above the cover plate with the spray nozzles which can be supplied with liquid via a supply line, and that the collecting channel is connected to a waste water connection by means of a pump device.
the resulting unit from the hood box can be adjusted in its dimensions to the usual grid dimensions of a ceiling cladding, a coffered ceiling or the like, so that these extractor hoods can be easily integrated into such a ceiling, the installation of the extractor hoods simultaneously with the laying of the ceiling or also can be done later at any time.
the ring-shaped exhaust air chamber, the central suction chamber with its circumferential air inlet and the separator inserts distributed along the circumference of the exhaust air chamber lead to large extraction and ventilation capacities even with smaller units, whereby the exhaust air can be extracted through the ceiling-mounted air ducts and the Cleaning liquid is to be disposed of by means of the sewage connection via a sewerage network on the ceiling.
the all-round separator inserts are located in the direct spraying area of the central spraying device, which therefore achieves a good cleaning effect even with small amounts of liquid. Since the units are completely equipped with the appropriate units, such as pumping devices and, if necessary, ventilation and lighting devices, they can be used individually or in groups to form larger units without any retrofitting work.
a suitable circuit can also be set up for the cleaning liquid, so that the waste water supplied to the waste water connection via the pumping device is processed and can be fed back to the spraying device, the circuit water or fresh water of course, washing and solvent can also be added via a suitable metering device.
the spraying device can have an all-round spraying spray head or a ring line with radial spray nozzles, but it is particularly advantageous if the spraying device consists of a spray arm which is rotatably mounted about a vertical axis, so that the spray arm rotates when a liquid is applied and rotatably sprays the grease separator inserts one after the other in regions, which ensures a high cleaning effect with low fluid consumption.
the structural unit can be closed off with a cover plate covering the entire cross-sectional area, which may even form the collecting channel itself or have passage openings for the drainage of the cleaning liquid into a suspended collecting channel, which creates an external air inlet with an edge extraction for the exhaust air.
the cover plate of the suction chamber which essentially covers the center area within the exhaust air chamber ring, is preceded by an inflow funnel which covers the cover plate-free ring area, so that the outflow air is exhausted via this inflow funnel, which exhaust air is then radially outward again from the inflow funnel along the underside of the cover plate by the one formed here Slot channel of the air inlet penetrates into the suction chamber.
This inflow funnel allows the use of a relatively small cover plate, which can be removed without difficulty even with a built-in extractor hood and enables easy access to the internal spraying device and the grease separators for any maintenance work.
cover plates and / or flow funnels form guiding surfaces for the cleaning liquid that are inclined towards the outer circumferential gutter, the cleaning liquid is drained from the hood into the outer gutter without risk of dripping, which has a sufficiently large receiving volume even with smaller cross-sections and ensures proper wastewater disposal.
An extractor hood 1 consists of a hood box 2 with a suction chamber 4 having an air inlet 3 and an exhaust air chamber 6 opening into an exhaust air connection 5.
the exhaust air chamber 6 extends in a ring around the central suction chamber 4 and is connected to it via an air passage 7, the Air passage 7 is composed of flow openings 8 arranged all around, which are equipped with grease traps 9.
the suction chamber 3 has a cover plate 10 which covers the central region within the exhaust air chamber ring and which is preceded by an inflow funnel 11 which covers the outer ring region which is free of the cover plate.
This inflow funnel 11 leads to a central extraction of the exhaust air, with an all-round, the air inlet 3 forming between the outer edge of the cover plate 10 and the inner edge of the inflow funnel 11 Slot channel 12 is formed.
a cover plate 13 is provided which covers the entire cross section of the hood box 2 and which, in the outer edge area with the opposite exhaust air chamber wall, delimits a circumferential slot channel 14 as the air inlet 3.
An inflow funnel is missing here and there is an edge extraction of the exhaust air.
a cleaning device 15 which comprises a central spray device 16 arranged above the cover plates 10, 13 for spraying out cleaning liquid.
the spray device 16 has a spray arm 17 which is rotatably mounted about a vertical axis and has spray nozzles 18, and a collecting channel 19 running around the edge serves to collect and discharge the sprayed cleaning liquid, a pump device 20 ensuring that the collecting channel 19 is connected to a waste water connection 21.
a supply line 23 that can be controlled via a solenoid valve 22 is set up, wherein the waste water connection 21 and the supply line 23 can be parts of a cleaning liquid circuit in a manner not shown.
the hood box 2 forms a rectangular unit in plan, which can be fully equipped and prepared for installation.
This unit is in the form of a cassette element of a conventional coffered ceiling or other arrangement of a ceiling cladding for kitchens or the like. Adapted and can therefore be integrated into such a ceiling at any time, with only the corresponding Fortlurt connection or water and electrical connection then being provided is.
the exhaust air (see arrows) is sucked into the suction chamber 4 via the air inlet 3, for which purpose A suitable negative pressure is applied, for example, via the exhaust air connection, from which suction chamber 4 the exhaust air penetrates through the air passage 7 into the exhaust air chamber 6.
the waste water passes through passage openings 24, 25 in the inflow funnel 11 or in the cover plate 13 into the collecting trough 19, the cover plates 10, 13 or the inflow funnel 11 forming outwardly inclined guide surfaces for better drainage of the cleaning liquid, and then from the collecting trough 19 the waste water for disposal via the pumping device 20 is conveyed to the waste water connection 21.
