Definitions

  • Exhaust ducts or hoods of this type are parts of exhaust systems of large and catering kitchens.
  • systems for aerosol and aerosol treatment are used. It uses special lamps that produce UV-C light and ozone. They are in the flow direction behind the filter segments, which are often aerosol, arranged and cause a photolytic oxidation of the organic substances contained in the irradiated area, eg. As the aerosolates and odors. This results in a reduction of the Aersosolatbelastung in the exhaust air system and the odor emission into the environment. Excess ozone is naturally converted back into oxygen.
  • the kitchen exhaust ducts or hoods are connected during assembly with an exhaust air system, which includes a fan, and at the same time connected to a differential pressure switch.
  • the air purification system can only be put into operation in conjunction with the exhaust air system. This prevents ozone can escape into the operating rooms.
  • Object of the present invention is to provide a kitchen exhaust duct or a kitchen exhaust hood of the type mentioned in such a way that the leakage of UV light is always reliably avoided.
  • the invention is therefore based on the following principle:
  • the individual filter segments are removed from the guide means along which they are displaceable, only at a single point, which could be referred to as a "lock” removable.
  • a locking insert as a "placeholder” so that the filter segments can not reach the lock.
  • the locking insert cooperates with an electrical switch. Only when it is used, the current flow to the UV lamp is released.
  • the locking insert To remove filter segments, for example, for replacement or cleaning, the locking insert must first be removed, which is immediately connected to the shutdown of the UV lamp. Only then can the filter segments be moved into the area of the gap or "lock” and taken out of the housing one after the other.
  • the locking insert has an outer part and a slide guided in this, which can be guided against the force of a spring device in a position and locked in this, in which the electrical switch is actuated.
  • a locking pin may be provided which is guided displaceably in the outer part and the inner end can be latched in a certain relative position between the outer part and slider in a recess of the slider. The locking of the slider relative to the outer part of the locking insert can thus be solved by simply pulling out the locking pin.
  • the slider in its extended position engages under a portion of a holding element such that the locking insert can not be removed.
  • the slider thus fulfills a second function, namely that of holding the locking insert in the housing. Only when retracted slide the locking insert can be removed.
  • the slider should have a handle on which it can be moved relative to the outer part of the locking insert.
  • a kitchen exhaust duct is shown and provided overall with the reference numeral 1, which is designed as a so-called. "Edge channel".
  • the kitchen air duct 1 is arranged in a solid angle between a vertical room wall and the ceiling.
  • it comprises a housing 2 which is formed by two end walls 3, a cover wall 4, a bottom wall 5, a rear wall not visible in the drawing and a profiled front wall 6.
  • the individual walls 3 to 6 are made of sheet metal parts; they are detachably joined together. However, at least the top wall 4 and the rear wall of the remaining housing 2 are removable.
  • the front wall 6 has at the top a first strip-like region 6a, which is vertically aligned and merges at its lower edge into a second strip-like region 6b, which points obliquely upwards. Below of the second strip-like region 6b is followed by a third strip-like region 6c, which is wider than the regions 6a and 6b and points obliquely downward.
  • a slot-like opening 7 Over almost the entire length of the third region 6c of the front wall extends a slot-like opening 7, in which in a manner shown below, a plurality of modularly joined filter segments 8 and further, explained below components are used.
  • the filter segments 8 are preferably aerosol and have known construction; they are designed so that they can deposit the fat, which is carried by flowing air, on corresponding surfaces.
  • Each filter segment 8 has a length which makes up only a fraction of the total longitudinal extent of the kitchen exhaust duct 1, so that therefore always a plurality of such filter segments 8 is inserted into the opening 7.
  • a profiled rail 9 extends along the inner edge of the front wall 6 along the upper edge of the opening 7 and along the lower edge of the opening 7, likewise on the inside of the front wall 6, a further profiled rail 10
  • the profiled rails 9 and 10 are designed so that they can each receive the upper or lower edge of the filter segments 8 in such a way that the filter segments 8 in the longitudinal direction of the rails 9, 10 can be moved.
  • the upper profile rail 9 comprises a downwardly bent edge region 9a, which, however, does not extend over the entire length of the rail 9 away, but to the right in Figure 2 right end leaves a gap 9b. The meaning of this gap 9b will be clearer below.
  • the lower rail 10 has an upwardly bent edge portion 10a, which extends over its entire length, so none of the gap 9b has comparable gap.
  • the upper or lower edges of the filter segments 8 lie with their inwardly facing surface on the edge regions 9a, 10a and with their outwardly facing surface on a tread rib 11 and 12, which forms the upper or lower edge of the opening 7.
  • the filter segments 11 at all points except the region of the gap 9b in the upper rail 9 is not removable between the rails 9, 10 and the area 9c of the front wall 6 of the housing 2 held.
  • the region of the gap 9b which has a length which corresponds approximately to the length of a filter segment 8:
  • the upper edge of a filter segment 8 pushed back and there located filter segment 8 from the rails 9, 10 dug and then a total of removed at the front.
  • the strip 12b of the holding plate is subdivided into two tabs 12ba and 12bb.
  • the plunger 14 or at least the caster 15 of the limit switch 13 protrudes through the opening 16 of the Haltebleelements 12 into the interior of the housing 2, so that he or she can be reached and operated from there.
  • the locking insert 17 comprises an outer part 17a made of sheet metal, the upper and lower edge is folded over twice by 90 °, so that thus form up and down groove-like guides.
  • a slider 17b In these groove-like guides, the upper and the lower edge of a slider 17b is guided. Also, the slider 17b is a sheet metal part; he is at all edges, including those who are perpendicular to the rails 9, 10, at least once folded by 90 °.
  • a bow handle 18 On the slider 17b, a bow handle 18 is fixed, whose legs are passed through two horizontal slots 19 in the outer part 17a. With the help of the bow handle 18, therefore, the slider 17b relative to the outer part 17a can be moved to the extent that allows the size of the slots 19.
  • an axially displaceable locking pin 20 is passed through the outer part 17 which can engage in a certain relative position between slide 17b and outer part 17a in a bore 21 of the slider 17b.
  • the locking pin 20 is spring loaded so, that he tries to move inwards, ie in the direction of the slide 17b.
  • the different filter segments 8 adjoin the locking insert 17 on the side opposite the holding element 12.
  • a compensating plate 23 is inserted, which optionally via adjusting screws, which allow a tolerance compensation, with an edge on one side surface 3 of the housing and the other edge on the adjacent filter segment 8 is supported.
  • the compensating plate 23 is adjusted so that it and the various filter segments 8, the locking insert 17 and the Garellement 12 in the assembled state remain in frictional engagement with each other, so that no translucent gaps arise between the individual parts.
  • the slide 17b is extended by appropriate actuation of the handle 18 against the force of the leaf springs 22 so that its corresponding edge engages with the fold 17ba under the two tabs 12ba, 12bb of the support member 12 and the plunger 4 of Limit switch 13 is actuated via the caster 15, so that the circuit is closed to the UV lamp.
  • the slider 17b is held in this spring-loaded position by the locking pin 20 in the opening 21 of the slider 17b is engaged.
  • UV-C light generating special lamps are arranged, which are not shown in the drawing. These special lamps cause a photolytic oxidation of the organic substances contained in the exhaust area, in particular Aerosolat- and odors. In addition to UV-C light, ozone is also produced; both must not escape into the operating rooms.
