Definitions

  • the invention relates to a goods counter, in particular a refrigerated counter e.g. for meat products with the features listed in the preamble of claim 1.
  • the counter contains a platform for the support of goods and this goods platform is surrounded in particular by cooled air which is guided over the goods support area.
  • the goods support area is usually covered by counter glazing to protect the goods from the surrounding area.
  • the goods are often manually removed and put back several times. This means that impurities in the form of e.g. of bacteria, fungi, viruses or microorganisms in general.
  • Moisture in the form e.g. of condensation is easily stored in the air flow area below the goods platform in the form of e.g. from puddles or stagnant fluid that are bacterial breeding sites.
  • this area does not necessarily have to be level and horizontal. It only depends on the suitability for placing goods.
  • DE 31 05 886 A1 describes a goods counter of the aforementioned type.
  • this goods counter disinfection of the goods lying on a goods platform is achieved in that two ionization tubes are arranged on an operator-side outlet opening for a circulating air stream.
  • the circulating air flow is thereby enriched with ionized gas particles, which are a disinfection the surface of the goods.
  • the resulting ionized particles are relatively short-lived and cannot or only to a limited extent have a disinfecting effect in the counter space located below the goods platform.
  • the invention has for its object to provide such counters so that the hygiene is improved.
  • This object is solved by claim 1.
  • UV radiation source e.g. a UV lamp, especially one with non-ozone-forming UV-C radiation
  • This radiation source below the goods platform initially prevents direct and also indirect exposure to the goods by UV rays. This would otherwise be decomposed by the UV rays or grayed out in the case of meat products.
  • the guide walls of the air flow below the goods platform, which are acted upon by the UV radiation are of such a surface shape that radiation reflection is brought about. This effect ensures that all room boundary walls are completely irradiated even when only one point light is used. The surface areas that are not directly affected by the radiation source are then at least indirectly affected by reflected radiation, and germ brood sites are thus effectively combated. This reflection effect is further improved by claim 4.
  • the floor arrangement of the radiation source according to claim 8 ensures that it is located in the most intensely flowing area of the air flow and thus ensures a particularly effective exposure to radiation.
  • the positioning of the UV radiation source within the meaning of claims 9 and 10 ensures that the air flow is largely disinfected before it enters areas which are problematic for counter hygiene, such as the cooling area, the fan area, or subsequently a perforated plate or filter area.
  • the overall hygiene effect is also determined by the number of air cycles per unit of time.
  • the space influenced by the radiation source is particularly shielded by the fact that in the inflow and outflow area of the air flow, the air flow channeling end walls extend downward from the goods platform, which force the air flow into the floor area of the radiation room and the escape of secondary radiation into the area above the Prevent the goods platform even more effectively.
  • the counter body 1 contains an essentially horizontal goods platform 2 for supporting goods 3, which is represented here schematically by a spatial body.
  • the goods receiving space 4 above the goods platform 3 is shielded by counter glazing 5.
  • This shield initially serves to protect the goods 3 or the goods receiving area 4 towards the buyer side 6 of the surrounding area. From the buyer's side 6, the goods 3 can be viewed through the counter glazing 2 for selection purposes without direct contamination having to be provided from this side.
  • the goods receiving room 4 is accessible from the operating side 7.
  • the opening area 8 can be closed by a likewise transparent flap. However, it is often open to e.g. to enable the butcher on the operating side 7 to remove the goods 3 simply and quickly.
  • the counter glazing 5 and possibly also the closure in the opening area 8 as well as side walls (not shown here) form a space boundary of the goods receiving space 4 above the goods platform 2.
  • These space delimitation surfaces enable a directed air flow or air circulation in the direction of the arrow 9 around the goods platform 2 and thereby over the area of the lying goods 3.
  • This air flow 9 is cooled in particular.
  • a cooling unit 10 in its area before entering the goods receiving room 4, e.g. in the form of an evaporator with a fan 11 arranged behind it in the flow direction 9 for generating the air flow.
  • the irradiation room 12 with a UV light 13 as the UV radiation source is located below the goods platform 2.
  • the air stream washing around the goods platform 2 in the direction of the arrow 9 is forced through the radiation chamber 12.
  • the air circulation around the goods platform 2 takes place in the embodiment counterclockwise.
  • the irradiation area 12 is bounded at the top by the goods platform 2 and at the bottom by a floor pan 14.
  • the floor pan 14 is provided on its outside with thermal insulation 15, which also continues upwards in the side areas in order to reduce or prevent cold loss downwards and to the sides.
  • the side boundary walls of the irradiation room 12 running in the plane of the drawing are not shown in the drawing. They are also equipped with thermal insulation 15.
  • the radiation walls 12 to the inflow channel 16 and to the discharge channel 17 are largely partition walls 18 and 19 formed as curtain-like downward directed guide screens from the boundary edges of the goods platform 2, which are effective with their surface facing the radiation chamber 12 as radiation reflectors and with them Irradiation chamber 12 facing surface form guide walls for the air flow or air circulation taking place in the direction of arrow 9.
  • the space boundary surfaces of the irradiation room 12 formed by the side walls, not shown, by the curtain-like boundary walls 18, 19 and above by the goods platform 2 and below by the floor pan 14, are smooth and preferably made of metallic material, e.g. made of stainless steel or aluminum - as far as it was compatible. Metallized surfaces can also be used. Other goods-compatible surface coatings or designs are also conceivable.
  • the said boundary surfaces facing the radiation chamber 12 are polished or mirrored.
  • the floor pan 14 In its deepest area, the floor pan 14 is provided with a water drain 20, which is equipped with a siphon 21 as a receiving space for a water reservoir 22 which shields downward.
  • the space below the platform 2 that is to say the radiation chamber 12, is supplied by a water supply 10. which is thus also in the area of exposure to the UV light or UV radiation, and the exposure is only achieved indirectly through reflection.
  • the UV lamp 13 is splash-proof.
