Definitions
- the invention relates to an extractor hood according to the preamble of claim 1 for the extractor hood over hobs.
- Extractor hoods are known as recirculation hoods and as exhaust hoods.
- Recirculated air hoods return the air extracted above the hotplate back to the kitchen after it has been passed through a grease filter.
- Exhaust air filters convey the air extracted via a hotplate, filtered or unfiltered, depending on the type of appliance, from the kitchen to the outside outside of a building.
- the invention can be used for both types of hoods.
- the object of the invention is to provide a means by which an effective air curtain is also generated if the components required for generating the return flow and the air curtain are suitable for different types and / or for different sizes of extractor hoods and for different installation situations are used, for example with a greater or lesser height distance above the hotplates, shorter or longer exhaust air paths, between immediately adjacent kitchen furniture or freely arranged without adjacent kitchen furniture.
- an adjusting device is provided for setting the volume fraction, which is branched off from the main flow of the main flow path as a return flow into the return flow path in order to generate the air curtain.
- Vapors of steam over hotplates are prevented from spreading beyond the inlet of the air curtain by the air curtain and are thus better detected by the fan.
- the steam vapors can be easily captured and extracted with a lower volume flow of the fan.
- the lower volume flow is particularly advantageous for exhaust hoods, especially in winter, because it means that less heat is dissipated from the kitchen and thus energy consumption for heating purposes is reduced.
- the air curtain can be formed not only near the front of the hood, but also near both of its transverse sides. 4.
- the blower can be made smaller or less powerful because of the lower volume flow required. This results in a reduction in manufacturing costs and operating costs.
- Extractor fan required. Additional fans or other aids are not required.
- the setting of the extractor hood can be varied with respect to the return flow branched off from the main flow for the air curtain and can be adapted by the user to various operating characteristics of the extractor hood.
- FIG. 2 shows a front view of the extractor hood from FIG. 1.
- the extractor hood for extractor above cooking parts shown in the drawings contains, seen in the extractor direction, one after the other an extractor inlet 2 on the underside of the hood, a grease filter 4 for cleaning the extractor flow 6, a blower 8 for extracting extractor via cookers and thus for generating the extractor flow 6, and an extractor outlet 10.
- the extractor hood shown in the drawings is an exhaust hood, which directs the extractor stream 6 into the free outside of the building, for. B. over a fireplace or over a chimney 12.
- the extractor 10 passes the cleaned extractor stream 6 back into the room, for. B. Kitchen in which the extractor hood is arranged above a hotplate.
- a dividing device 16 preferably in the form of an adjustable flow restrictor, is arranged downstream of the blower 8 in the main flow path 14.
- a branch 20 is formed in the main flow path 14 between the blower 8 and the adjusting device 16, at which a return flow path 22 branches off from the main flow path 14 and extends downwards at least over the width of the hood front side, but preferably also over the width of the hood transverse sides has directed air outlets 24 or 24-1 and 24-2 for generating air jets 26 or 26-1 and 26-2, which form a kind of air curtain that shields steam rising from a cooking area from the outside and together with this steam and / or ambient air is sucked out again by the blower 8 through the vapor inlet 2 and the grease filter 4.
- the volume fraction can be set, which is branched off from the fume extraction stream 6 as the return flow 34 in the return flow path 22 to form the air curtains 26, 26-1 and 26-2.
- the adjusting device 16 is connected to an electronic control device 30 and is set by the latter as a function of the operating conditions of the extractor hood.
- Such operating conditions can be, for example, properties of the fume extraction stream 6, in particular its density, which can change depending on the proportion of the steam in relation to the ambient air drawn in.
- Other operating conditions that can be used to regulate the volume fraction can be the size of the electric current of the fan.
- Further operating conditions can be: The flow rate of the fume extraction stream 6 in the main flow path 14, the temperature of the fume extraction stream, the speed of the fan 8, etc.
- the control device 30 can have an appropriate sensor means.
- a manual setting element 36 can be provided for setting the setting device 16 and thus for setting the volume fraction of the return flow 34 in the fume extraction flow 6
- the fume extraction stream 6 is the main stream. It consists of air and possibly vapor (steam) and at least part of the return flow 34, all of which are sucked in by the fan 8 through the vapor inlet 2. Due to a damming effect on the adjusting device 16 (throttle), only a main part of the fume extraction stream 6 passes as exhaust air 32 through the fume outlet 10, while a smaller portion flows as a return flow 34 through the return flow path 22.
- the air outlets 24, 24-1 and 24-2 can be round, slot-like, or other openings. Overall, they have a smaller flow cross-section than the return flow path 22 and therefore act as nozzles which generate downward-directed air jets which form the air curtain 26, 26-1 and 26-2.
- the adjusting device 16 can also be a flow switch instead of a flow restrictor.
- the grease filter 4 can be omitted if desired for exhaust hoods that conduct the fume extraction stream 6 outside: In this case, it is advisable to use a grease filter in the return flow path 22.
