Definitions
- the present invention relates to a method and a Device for cleaning exhaust air from kitchen appliances, such as Steamers, grills, ovens and the like. Under “Cleaning” is also the removal of steam from the exhaust air Roger that.
- a device for cleaning exhaust air is also generally known Known kitchens, with an exhaust air duct for discharging exhaust air from the kitchen appliance, a pressure increasing device for increasing the pressure in the exhaust air, a liquid bath and a supply line for discharging exhaust air into the liquid bath.
- the device this prior art and the method that can be carried out with this device for cleaning exhaust air have considerable disadvantages. Most of all is one Removal of undesirably high amounts of heat from the liquid bath is very limited or not possible at all. The natural cooling of liquids in closed Containers is very limited. Such is the use of the device according to GB-A-2281230 not possible in closed rooms directly on the kitchen appliance.
- the present invention is therefore based on the object of a method and a Device for cleaning the exhaust air from kitchen appliances, such as steamers, grills, To create ovens and the like with or with the cleaning of Effective exhaust air is made possible in a simple manner and accordingly inexpensively.
- the liquid bath is advantageously continuous or intermittently fresh liquid and Liquid drained from the bath. It becomes a rubbish prevents the liquid bath and continuous operation of the Kitchen appliances enables.
- a first alternative while fresh liquid continuously in the liquid bath fed, making the fluid exchange easy Way is made possible.
- the supply of fresh liquid can also be carried out batchwise respectively.
- Another advantage results from the fact that simple Way, the cleaned exhaust air via an exhaust air discharge device is freely applied. The cleaned exhaust air is thus returned to the ambient air.
- the present invention also has an apparatus for Cleaning exhaust air from kitchen appliances, such as steamers, grills, Ovens and the like the subject.
- She points an exhaust air duct for extracting the exhaust air from the kitchen appliance, a pressure increasing device for increasing the Pressure in the exhaust air, a liquid bath and a supply line to supply the exhaust air to the liquid bath.
- the device according to the invention for cleaning exhaust air from kitchen appliances is distinguished is characterized in that an additional heat dissipation device for active removal of heat introduced into the liquid bath by the exhaust air is provided. This will turn on easily created the possibility of an exhaust air purification device.
- the liquid bath is preferably in a container, arranged in particular a closed container, the has an overflow to form a liquid level.
- a container arranged in particular a closed container
- the liquid level With the help of the liquid level, the amount of liquid limited in the container and can be caused by the overflow too much liquid is being dispensed.
- the feed line advantageously opens near the floor of the container, so that the exhaust air exiting there essentially the entire height of the liquid bath flows through.
- the device according to the invention advantageously has a heat dissipation device for removing heat brought into the liquid bath by the exhaust air on. This avoids that from a certain point in time Exhaust air cleaning heated the liquid bath too much becomes and begins to evaporate itself.
- the heat dissipation device is a heat pipe exchanger, so-called heat pipes are formed. This not only enables effective heat dissipation, but also the use of standardized and therefore cheaper Components.
- the pressure increasing device a compressor, for example a radial compressor is, which also increases the pressure in a simple manner is made possible in the exhaust air.
- this compressor can also in the case where the kitchen appliance does not have an exhaust air discharge device has the exhaust air from the kitchen appliance be actively suctioned off.
- a fresh air supply device can also be used at the pressure booster be provided in the event that there is not enough exhaust air is available and the exhaust air then with the fresh air is mixed and introduced into the liquid bath. It is to be prevented that too much exhaust air is emitted is sucked off the kitchen appliance.
- the present invention becomes the excellent achieved with the kitchen appliances Maintain the cooking result.
- water is the effective liquid agent intended.
- the water becomes a special advantage only little or no foaming detergent added, which in particular collects smoke particles can be significantly improved from the exhaust air.
- the size is appropriate short and the cable lengths are also kept to a minimum shortened. Due to the cleaned exhaust air there are additional Exhaust ducts from the kitchen to the outside are unnecessary.
- FIG. 1 schematically shows a device according to the invention shown for cleaning exhaust air from kitchen appliances.
- this device also the invention Process for cleaning exhaust air from kitchen appliances be performed.
- the device 1 has an exhaust air line 3 for discharging the exhaust air from the kitchen appliance (not shown) according to arrow 5.
- the exhaust line 3 is one Pressure increasing device 7 provided, with the help the pressure in the exhaust air can be increased.
- Via a feed line 9 the air is introduced into a container 11, in which a liquid bath 13 is located.
- a filter 17 arranged, for example, a sintered metal filter is.
- the exhaust air enters through this filter the liquid bath 13 from.
- a liquid supply channel 19 is continuous or discontinuous liquid in the liquid bath 13 introduced, as indicated by arrow 21.
- the liquid bath 13 is limited in the container 11 by that due to a side overflow 23 a maximum fill level in the liquid bath 13 is formed is in the form of a liquid level 25.
- the exhaust air flows from the mouth opening 15 through the filter 17 into the liquid bath 13 and rises to the top, the exhaust air as it passes through the liquid bath 13 is cleaned. Is above the liquid level 25 a discharge duct 27 is also provided for the cleaned exhaust air, which then the container 11 via the discharge channel 27th leaves according to arrow 29.
- the liquid bath 13 is heated by the hot exhaust air.
- a heat dissipation device 31 is provided in order to prevent the liquid bath 13 from overheating, and the heat rise, for example to 60 ° C restrict.
- the heat dissipation device formed from so-called heat pipes. These include a heat pipe transmitter 33 on the parallel to each other extending heat dissipation plates 35 are provided.
- the heat-conducting plates 35 arranged in the liquid bath 13 absorb the heat and transfer it to the medium in the heat pipe exchanger 33. Outside the container 11 flows the heat dissipation plates 35 ambient air according to arrows 37 over and cools the heat dissipation plates 35 excess heat from the liquid bath 13 on simple Spread out wise.
- the exhaust air not only steam but also smoke particles, May contain fats and oils that go to the bottom of the container 11 sink in the liquid bath 13 is a drain device for this provided, for example in the form of opening the bottom plate 39 of the container 11. It can also if necessary, the entire liquid bath 13 can be drained.
- the steam content can be particularly advantageous approximately 100% of the exhaust air is removed.
- the container 11 or the liquid bath 13 can be so large dimensioned that feed lines 9 from several kitchen appliances open into a container 11.
- the feed line can also 9 several inlet channels with corresponding mouth openings have so that a larger amount of exhaust air simultaneously through several filters into the liquid bath 13 can be introduced.
- the flowing past according to arrows 37 Air can otherwise be used for heating become.
- the heat dissipation device 31 can also be designed so that the heat emission side itself in a container with liquid, for example fresh water, stands, and this fresh water is heated accordingly, which in turn can be used as hot water can.
