Definitions

  • the invention relates to a ventilation ceiling, of the type known from, for example, DE-A-2718611.
  • Such a ventilation ceiling can be found in, for example, the kitchen of a hospital or retirement home.
  • Said ceiling contains air supply and air discharge elements, and possibly also light fittings.
  • the air discharge elements increasingly serve the purpose of removing grease etc. from the extracted air, so that they act as air filter elements.
  • said air discharge elements are designed as double-walled coffers which have supply and discharge openings in the walls and grease extractors disposed in said coffers.
  • DE-A-2949235 discloses, for example, double-curved coffers which are square in top view.
  • Channel parts are detachably disposed below the edges thereof. The idea is to remove those channel parts regularly, in order to clean them.
  • the coffers themselves can be cleaned by removing them from the ceiling and placing them in a dishwasher. Removing the channel parts regularly is troublesome, and is therefore often left undone. In practice, the channel parts are cleaned only when they are full to the brim, and grease and the like is dripping out of them.
  • This system comprises a mobile stock tank with aqueous cleaning agent, a pump and a flexible hose.
  • the idea is to place the outlet of the hose in a channel part by hand, following which aqueous cleaning agent is pumped into said channel part through said hose. It is expected that the cleaning agent will loosen and dissolve the grease and the other constituents in the channel and will take them to the grease-collecting vessel.
  • the object of the invention is to make a further improvement in the solution to the problem of cleaning ventilation ceilings.
  • a fixed supply line for cleaning agent should be provided, in order to introduce the cleaning agent directly into the channel elements, and said supply line is adapted so that it can dispense cleaning agent at intervals.
  • a manifold element is preferably incorporated in the supply line, in order to connect the supply line to each channel element.
  • the channel elements it is preferable for the channel elements to open out into a common trough, in order to discharge cleaning agent and substances removed from the channel elements to a grease-collecting vessel.
  • the trough is amply dimensioned for processing a volume per unit time which is at least equal to the sum of the volumes to be processed by every channel element in that unit of time.
  • the channel elements and/or the trough element may be clad with a friction-reducing and/or adhesion-reducing material, such as teflon.
  • heated cleaning agent for example at a temperature of approximately 70°C. This can be flushed through the channel elements every 24 hours for, say, 5 minutes.
  • heated cleaning agent for example at a temperature of approximately 70°C.
  • This can be flushed through the channel elements every 24 hours for, say, 5 minutes.
  • the loading of the ventilation system which depends on, for example, the type of kitchen and the type of equipment present in the kitchen, it is possible to flush more frequently and for a longer period in each case, or indeed less frequently and for a shorter period.
  • the person skilled in the art will easily establish an optimum for the frequency and duration of the flushing by carrying out simple experiments.
  • a ventilation ceiling 1 is shown in the drawing, in particular in Fig. 1.
  • Said ceiling is essentially composed of channel elements 2 running virtually horizontally at a distance from and parallel to each other, which elements are bridged by cylinder-segment-shaped panel elements 3, 4.
  • the channel elements are, for example, three metres or more in length.
  • each panel element 3, 4 rests with its side edges on a respective channel element 2.
  • the panel elements 3 are double-walled, as shown in Fig. 3, and are perforated. Air is extracted from the space below the ventilation ceiling through these panel elements 3.
  • the perforations 15 in one wall of the panel elements 3 are staggered relative to those in the other wall.
  • the panel elements 4 are single-walled and unperforated. They do not contribute to the ventilation.
  • the channel elements are connected to a horizontal beam 9, which runs parallel to the trough-shaped elements 7, 8 and which is suspended from wires 10.
  • a light fitting 5 and an air supply element 6 are also accommodated in the ventilation ceiling 1. Both likewise rest with their side edges on respective channel elements 2.
  • the arrangement of the panel elements 3, 4 and the fittings 5 and the air supply elements 6 can be adapted to requirements in each case, and is determined by, for example, the positioning of cookers etc.
  • the ends of the channel elements 2 lead into virtually horizontal, trough-shaped elements 7, 8, and rest on a side wall thereof. These trough-shaped elements 7, 8 are positioned essentially at right angles to the lengthwise direction of the channel elements 2.
  • the channel elements 2 slope down slightly in the direction of the trough 7.
  • the troughs 7 and 8 each have a discharge pipe 14, which is connected to the conventional sewerage system.
  • the troughs 7 and 8 slope down slightly in the direction of the respective discharge pipe 14.
  • each channel element 2 is connected to a respective outlet 13 of a manifold 11 of a fixed pipe 12 for the supply of a cleaning agent.
  • Said pipe 12 accommodates a shut-off valve (not shown), which can be opened with a timer-operated solenoid (not visible).
  • the pipe 12 is connected to the conventional water mains, and runs through a heating element (not shown).
  • a distribution unit (not shown), which is generally commercially available, is also connected to the pipe 12, for mixing a cleaning agent into the tap water.
  • a control panel for programming the flushing can be set up in an easily accessible position in the kitchen.
  • the cleaning agent Due to the fact that the liquid flows gently through the channel elements 2, the cleaning agent has sufficient time to loosen and/or dissolve the greases etc., following which they are entrained with the flow. There is therefore no need for a mechanical action of the liquid, as would be the case with powerful liquid jets. Nor is there any risk of overflowing over the channel elements 2, which are open at the top side. It is sufficient if during the flushing the channel elements are filled no more than halfway up with liquid.
  • the trough 7 is amply dimensioned to collect such a quantity of liquid from all channel elements 2 opening out into it and to discharge said liquid into the sewer. Should a leakage occur in the manifold part 11, the trough 8 will serve as a drip tray, and will consequently prevent flooding.
  • the troughs 7, 8 can be connected to, for example, a water purification system, instead of a sewer.
