Definitions
- the invention relates to a refrigerated goods counter with the features specified in the preamble of claim 1 and a method for sanitizing such counters.
- the evaporator used to cool a recirculating air flow poses hygienic problems.
- the defrosting phases are problematic. After a certain operating time, evaporators usually ice up.
- the coolant supply to the evaporator is interrupted, in other words a compressor or a cooling device containing a compressor, which is usually arranged outside the cooling counter, is switched off.
- the ice formed on the cooling surfaces of the evaporator can now defrost. that the number of germs in the defrosting water increases at the higher temperatures, since the defrosting water can get to inaccessible or only inaccessible places of the goods cooling counter or the counter pan, with previous goods cooling counters each defrosting process provides a hygienic R isiko.
- the object of the invention is to provide a refrigerated goods counter and a hygiene process to propose for a goods counter that improves in hygienic terms are.
- This task is with regard to the refrigerated goods counter by claim 1 and with regard to the sanitation method solved by claim 18.
- the goods refrigerated counter according to the invention is a hot gas defrosting device to defrost the evaporator and the other one during the evaporator the defrosting phase directly with UV radiation available.
- the procedure is such that during hot gas defrosting Evaporator is exposed to UV radiation (claim 18).
- Hot gas defrosting can first be the time for defrosting shorten the evaporator to about 15 minutes.
- a hot gas line containing a controllable shut-off valve is connected on the input side to the evaporator and on the output side to the compressor of the cooling device (claim 2).
- the cooling device is preferably arranged at a distance from the goods cooling counter. For the hot gas defrosting only the shut-off valve has to be opened.
- the compressor conveys the coolant heated during compression directly into the evaporator.
- the hot gas line is a heat-permeable pipe, in particular a copper pipe. It has been shown that the defrosting of the evaporator takes place in a relatively short time even if it is supplied to the evaporator Hot gas "or the coolant has around room temperature.
- a complex insulation of the hot gas line can therefore be dispensed with. It may even be expedient to enlarge the outer surface of the hot gas pipe at suitable points with relatively high ambient temperature by means of structures similar to cooling fins in order to absorb the heat from the environment to increase (claim 4).
- the measure according to claim 6 ensures that the evaporator in an area spatially delimited from the goods area and the tub area is arranged.
- the demarcation is preferably effected by partitions. Water flowing out of the evaporator during the defrosting process can therefore not be without further uncontrolled get into the tub space bounded by the counter wall.
- the air filter covering the exhaust opening can be removed the evaporator is also light for regular, more thorough cleaning work accessible.
- the fan also in Ascent shaft is arranged between the evaporator and the air filter, it can also be easily cleaned from the outside or via the blow-out opening, which is made even easier by the fold-out according to claim 8 is.
- the fan according to claim 9 By arranging the fan according to claim 9, namely so that it is in the effective range of the UV sterilization tube, the formation of Germs in the area of the fan are prevented or existing germs become killed.
- the UV radiation source acts on both evaporators and Fan if it is arranged as specified in claim 10.
- Tub space which acts at least on the tub floor with cleaning fluid Spray device is arranged (Claim 11) .
- spray device is arranged (Claim 11) .
- the spray device preferably comprises a spray head arranged on the tub floor (claim 12).
- the outlet or spray openings of the spray head are preferably so aligned that the cleaning liquid mainly the floor area and less applied to the underside of the goods platform.
- the spray device can advantageously be fed directly from the drinking water network.
- a separate spray device proposed with which a detergent is additionally added to the tub area or can be sprayed onto the tub floor (claim 14).
- the spray device can also be fed from a storage container according to claim 15, from which, for example, a pump already contains a cleaning agent Cleaning liquid is removable.
- the spray device works in particular then effective if as little as possible according to claim 16 in the tub space Internals are available.
- a further advantageous embodiment of the product counter according to the invention exists in providing a control device with which both the hot gas defrosting device, the spray device, the fan and the UV disinfection tube is controllable (claim 17).
- the defrosting or cleaning processes are then carried out automatically without the intervention of an operator.
- the control device is preferably with a control device for cooling the goods refrigerated counter connected.
- the cleaning or defrosting processes are preferably carried out in predetermined time intervals that can be set on the control device.
- a product counter according to the invention comprises as main components a counter body 1, a counter trough 2 embedded therein, a goods platform 3, a front pane 5 arranged on the customer side 4 of the counter, on the operating side 6 of the counter a worktop 7, one above the goods platform arranged goods room 8 and one below the goods platform 3 arranged and bordered by the counter tub 2 tub space 9.
- an ascending shaft 10 is arranged, which extends in the longitudinal direction of the counter extending vertical partition 12 substantially from Tub space 9 is delimited.
- the partition 12 does not quite reach the floor, but leaves one Inflow opening 14 between its lower edge and the tub floor 15 free.
- the cooled air comes out at the top of the ascent shaft through a blow-out opening 17 in the direction of flow 18 into the goods space 8 out.
- the blow-out opening 17 is detachably fastened, in particular for Goods compartment 8 towards foldable air filter 19 covered.
- Seen in the direction of flow in front of the air filter 19 is at least one fan 20 with its lower end pivotably arranged such that it with the air filter removed or opened 19 from the blow-out opening 19 to facilitate its cleaning is.
- Between fan 19 and evaporator 16 is one in the longitudinal direction of the counter extending UV disinfection tube 22 positioned.
- the UV disinfection tube 22 acts on the evaporator 16 or its during the defrosting phases Cooling surfaces and the fan with UV radiation. During normal operation the counter, the UV disinfection tube is switched off.
- the goods refrigerated counter includes a control device 23 (see Fig. 2) with which during the defrosting of the evaporator the UV disinfection tube can be switched on, as well as other functions of the Goods refrigerated counter can be monitored and controlled.
- the at least one fan is 20 switched on and circulates the air in the direction of flow 18.
- a cooling device see Fig. 2 connected evaporator
- the air and accordingly, the goods 49 lying on the goods platform 3 are cooled.
- the Airflow constantly takes moisture out of the goods and also from the environment on, which condenses on the evaporator 16. With continued operation, this freezes condensed water to a steadily growing layer of ice and impedes the proper cooling of the circulated air.
- the evaporator is therefore in at regular intervals, for example before the start of sales and at the end of a sales day preferably defrosted as follows: one cooperating with the evaporator 16 Cooling system is switched off while at least one fan 20 continues to heat and thus defrost the evaporator accelerate. The defrosted water runs down on the evaporator and arrives finally on the trough bottom inclined towards a drain opening 25 15. During defrosting, the UV sterilization tube 22 is in operation and acts on the cooling surfaces of the evaporator 16 with UV radiation. An increase of germs contained on the evaporator or in the defrost water The increased temperature of the defrost phase is due to the exposure to Prevents UV radiation. Existing germs are killed.
- a spray head 26 is arranged adjacent to the tub floor 15 via a supply line 27 with interposed check valve 28 is fed to the municipal drinking water supply network.
- the spray head 26 is set so that the cleaning liquid or water in the spray direction 29 ejects.
- the spray direction of the spray head 26 runs in relative proximity to the tub floor 15.
- cleaning liquid passes through the inflow opening 14 also to those located below the evaporator 16 Area of the tub floor 15.
- the spray head 26, the supply line 27 and the spray valve 28 comprising stop valve need not be mandatory for everyone Defrosting operation.
- the evaporator 16 or its connection to the Cooling device 24 designed so that hot gas defrosting is possible.
- the Cooling device 24 is located outside the goods cooling counter, for example in a room under the counter location.
- the evaporator 16 has an evaporator inlet 30 and an evaporator outlet 32.
- the evaporator outlet 32 is connected via a suction line 33 to the input of a compressor 34 connected.
- the outlet 35 of the compressor is connected via a pressure line 36 a condenser 37 fluidly connected. From the capacitor output 38 leads a feed line 39, into which a collector 40 is interposed within the refrigeration system 24 to the evaporator inlet 30.
- a hot gas line 42 which is close to the Heat exchanger 37 opens into the pressure line 36.
- the capacitor 37 bypassed in the manner of a bypass.
- a hot gas shutoff valve 43 is switched on, which is connected via a control line 44 from the control device 23 can be controlled.
- the control device 23 continues to control the compressor 34 via a control line 45, via a control line 46 the shut-off valve 28 of the spray device, the UV disinfection tube via a control line 47 22 and via a control line 48 the at least one Fan 20.
- the cooling or hot gas defrosting device described works as follows: In normal operation, the fan 20 and the refrigeration system 24 are in operation. It will Circulating air flow with flow direction 18 generated on the goods platform 3 lying goods 49 cools.
- the control device 23 is adjustable that at certain time intervals, e.g. at the beginning and end of the Sales day, initiates a defrost process. First the hot gas shut-off valve 43 opened. As a result, what is heated during the compression process arrives Coolant bypassing the heat exchanger 37 directly into the hot gas line 42 and from there via the evaporator inlet 30 into the evaporator 16.
- Zum Defrosting the evaporator requires relatively small amounts of energy because it is not operated in the freezer area.
- the hot gas line 42 which can be very long under certain circumstances become.
- the coolant supplied to the evaporator via line 42 is ambient temperature having.
- a copper tube is preferably used for the hot gas line 42.
- the outer surface of the hot gas line 42 by about Type of fins 50 to enlarge structures formed. Cooling fins are 50 expediently arranged at those points on line 42 where there is an increased room temperature.
- the UV radiation acts on the spatial proximity of the UV sterilization tube to the evaporator 16 whose cooling surfaces and prevents Germ growth during the thawing phase.
- the defrost is due accelerates the heat given off by the sterilization tube.
- a Delay for example towards the end of the defrosting process, becomes the shutoff valve 28 open for water supply for about 5 to 10 seconds. This will Fresh water via the spray head 26 into the counter tub 2 or in the tub room 9 sprayed. The water drained from the evaporator goes into the drain opening 25 rinsed. The same applies to solid particles that are on the tub floor 15 have accumulated.
- the refrigerator is in the process of defrosting or the compressor 34 and the fan 20 in operation. The one from the fan circulated air cools down on the evaporator and prevents heating the goods 49 lying on the goods platform 3.
