Definitions
- the invention relates to a refrigerated counter for perishable foods, such as. B. Meat products.
- a counter comprises a body in which a counter trough is embedded, with a goods platform in the counter tub for supporting Goods is arranged.
- a goods room above the goods platform which is usually covered by counter glazing for hygienic reasons is.
- To cool the goods is a cooling device in an outside of the Arranged area lying area, with the help of a fan Circulated air flow is generated, the cooled air over the goods support area leads.
- the goods become multiple during a sales day removed and replaced.
- a cooling device is usually located in hard-to-reach places on the refrigerated counter, so that cleaning them is problematic for this reason alone. moreover are usually several cooling surfaces lamella-like close together in cooling devices ordered, which makes cleaning them more difficult.
- a refrigerated counter is known in which a UV radiation source together with a cooling device within a cooled for circulation Air-serving flow channel is arranged. The UV radiation source is included surrounded by an aperture, the effect of UV radiation on the cooling device prevented.
- the invention has for its object refrigerated counters of the aforementioned Kind to improve in hygienic terms. This task is accomplished through the combination of features of claim 1 solved.
- the cooling device is in the Effective range of the UV radiation source arranged and exposed to UV radiation.
- the UV radiation source consequently not only has a germicidal effect on those in the Flow channel circulates air, but also effectively prevents the The formation of germs on the cooling surfaces, which are generally difficult to access the cooling device, so that even with longer cleaning intervals none Contamination from the cooling device with germs is to be feared.
- the UV radiation source and the cooling device are preferably in the feed channel arranged, that is, in the channel through which the circulated air from the tub space is returned upwards to the goods area.
- the UV radiation source and the fan are preferably in the upper, with a feed opening into the area of the feed channel opening into the goods space arranged (claim 4). This meets the demand for sanitation as close to the goods room as possible.
- the UV radiation source placed in a flood-protected place. It is namely also conceivable to arrange a UV radiation source in the tub space. However, this would mean the regular cleaning work in the area of the counter tub to disturb. In addition, the UV radiation source would have to be watertight his. With an arrangement according to the invention, this is not necessary, it is sufficient here a splash-proof version.
- the fan is according to claim 5 arranged in the flow direction after the UV radiation source. This has the Advantage that the fan and the parts carrying it the source of UV radiation shield from the goods room. No UV radiation should get into the goods area, since this has a graying effect, especially on meat and sausage items.
- the surfaces are those exposed to UV radiation Boundary walls of the radiation room reflective. Thereby the effectiveness of the radiation is increased, so that even when used only a spot light the radiation room is largely irradiated. Surface areas, which are not directly affected by the radiation source, are then at least indirectly affected by reflected radiation and effectively combats germ brood spots.
- the advantage of the measure according to claim 11 is that the Fan can be misplaced from its operating position, making it itself can be easily cleaned and the UV radiation source behind it easily accessible for cleaning or repair purposes, for example.
- the circulating air flow is humidified.
- the water vapor in the radiation chamber is proposed self-supply (claim 14). This not only circulates Air, but at the same time the water vapor supplied disinfects.
- a counter body 1 is preferably a thermally insulated counter tub 2 worn.
- the counter tub there is an essentially horizontal goods platform 3 arranged to support goods 4, the goods being schematic is represented by a spatial body.
- the one arranged above the goods platform 3 Goods room 5 is shielded by counter glazing 6. This shield serves to protect the goods 4 of the goods room 5 to the customer side 7 of the surrounding area. From the customer side 7, the goods 4 can pass through the counter glazing 6 can be viewed for selection purposes without direct contamination must be provided on this side.
- the goods room 5 is accessible from the operating side 8.
- the opening area 9 can by a also be transparent flap closed. But it is open to many for example a simple one for the operators located on the operating side 8 and enable faster removal of the goods 4.
- This space limitation enables a directed air flow 10 over the goods support area of the goods platform 3.
- the air exits via an operator-side supply opening 13 and arrives in the goods room.
- the air flow 10 passes over on the customer side 7 a discharge channel 14 in the located below the goods platform 3 Tub room 15.
- a feed channel 16 is arranged, which extends from the bottom 17 of the counter tub 2 extends approximately to the underside of a worktop 18 on the operator side.
- the feed channel 16 is from the tub space 15 through a boundary wall 19 separated.
- the one located above the plan level of the goods platform Area of the operator-side boundary wall 24 of the radiation chamber 26 curved towards the goods area and thereby formed in the manner of a groove 27. In this way, a low-loss deflection area 28 for the air flow 10.
- the UV radiation source is at the bottom, ie the bottom 17 the counter tub 2 facing leg of the groove 27 is arranged.
- the flute-like area of the boundary wall 24 acts like a headlamp funnel and reflects part of the UV radiation downwards. This retroreflective or reflection effect is increased in that both the boundary wall 24 as well as the other boundary walls of the irradiation room 26 are reflective and e.g. consist of metal or are coated with metal. The reflective effect is even greater if the said surfaces are polished or are mirrored.
- a water vapor line 39 opens with a discharge opening 40.
- the other The end of the steam line 39 is connected to the steam space of a steam generator 41 connected.
- the UV radiation source is preferably a UV lamp with a non-ozone-forming one UV-C radiation. It can be designed in the manner of a neon tube, which is extends at least over a partial length of the counter. But there are also several punctiform UV lights conceivable.
