Definitions
- the invention relates to a refrigerator with a refrigeration device, an interior and a collecting device for condensate arising in the interior.
- the Invention a method for indicating germs in such a cooling device.
- Refrigerators are useful for short-term storage of various foods and foods suitable for different low temperatures.
- Design and arrangement of an evaporator e.g. plate-shaped, with or without evaporator compartment, integrated in the rear wall
- evaporator e.g. plate-shaped, with or without evaporator compartment, integrated in the rear wall
- Subdivision of the interior allow the groceries to the appropriate Store levels in the optimal temperature range for them.
- EP 312 060 B1 also describes an automatic cooling device with a device for Air circulation.
- a separate storage compartment is included in this cooling unit is limited by plastic material.
- the germs are killed by ultraviolet rays without the tray itself being exposed to the ultraviolet rays. at such a device is indeed a closed compartment in which germ killing done, but such a device for killing germs is not directly on the whole Storage space transferable.
- Ultraviolet rays are in shadow areas as well as in Biofilms and soiling on the food or storage containers not effective.
- biofilms are usually not visible. The user must therefore get away from it assume that undesirable in the refrigerator interior outside the locked compartment Bacteria or germs can be present. A time for a necessary cleaning cannot be derived from it. Again, the user is visible at Dirt thoroughly clean the inside walls. Then there is one Distribution / propagation of the germs is often well advanced.
- the invention thus presents the problem of creating a cooling device in which even an apparently clean interior is an indication of recommended interior cleaning occurs because the number of germs actually present is increased.
- the advantages achievable with the invention are, in particular, that the user already pointed out a sensible cleaning or a disinfectant renovation of the interior if a significant number of germs and / or spores or similar are present, but no visible contamination can be determined.
- This is in the Cooling device at least one measuring device for the early indication of germs and / or Spores arranged.
- This measuring device is advantageously composed of at least one sensor for the detection of bacteria, yeast, mold and / or their metabolic products, an evaluation electronics and / or a display element together. The right one The time for cleaning is determined in particular by comparison with the evaluation electronics stored limit values determined and signaled. Exceeds the current measured value Bacteria, yeasts, molds and / or their metabolites, e.g.
- Nitrite concentration is in a further advantageous embodiment a warning is given at regular intervals via a display element. This warning is given either optically and / or acoustically.
- the sensor is designed to measure the prevailing contamination in one place arranged, which is flushed with condensate from the interior of the cooling device.
- An arrangement of the sensor in or on a condensate trap is particularly advantageous or on the rear wall evaporator, because there is guaranteed wetting of the Sensor with condensate.
- the Condensate trap and the rear wall evaporator arranged a drip tray, which is in contact with the sensor.
- the senor is advantageously equipped as a nitrite sensor. This either directly records the nitrite present in the condensate or it is the oxidation as Measuring method applied and nitrite oxidized to nitrate.
- FIG. 1 shows a cooling device (1) in the form of a refrigerator, for a better overview the door (10) has been omitted.
- the refrigerator (1) has a heat-insulated housing an interior (2) with smooth side walls.
- the division of the interior (2) can be designed differently. Usually there is at least one, here Not shown, vegetable bowl and in several levels storage space for refrigerated goods. Naturally the interior (2) can also be divided in such a way that multi-part shells next to one another be inserted and / or in the upper area an additional freezer compartment is arranged.
- the refrigerator (1) can be equipped as a multi-temperature refrigerator.
- the cooling device (1) in at least two interiors (2) separated from one another to each divide separately assigned doors.
- a particularly good indoor climate leaves reach themselves with dynamic cooling. Here one ensures in the upper interior area arranged fan (9) for a good air flow and thus for even Temperatures throughout the interior (2).
- the refrigerated goods stored become a lot cooled faster.
- this measuring device includes, for example is designed as an electrochemical or biochemical sensor, at least one evaluation electronics (4) and advantageously also a display element (5). It becomes the total bacterial count determined directly or indirectly and with a basic limit value stored in the evaluation electronics (4) compared.
- the total germ count is the germ and spore load in the refrigerator (1), with high values for bacteria, mold and Yeasts are crucial. It is well known that a variety of mushrooms and Bacteria excretes nitrite. This knowledge allows from a determined nitrite concentration a conclusion on the degree of contamination of the interior (2) of the refrigerator (1) derive. Mushrooms, mold or the like are not always also visually recognizable, but through Nevertheless, biochemical sensors can be recorded directly or indirectly. If the measurement e.g. has high nitrite concentrations, e.g. > 1mg / l, can be simultaneously from one high germ load on the interior (2) can be assumed.
- the sensor (3) serves indirect germ detection preferably a detection of the metabolic products of Bacteria, yeasts and / or molds, e.g. Nitrite concentrations. This turns into nitrite either measured directly or oxidation is used as the measuring method and nitrite Oxidized to nitrate in order to deduce the degree of contamination of the interior (2).
- the sensor (3) is on to indicate that cleaning is necessary in good time at least one point of the interior (2) flushed with condensate. For example, arranging the sensor (3) on an evaporator (7) which secures Rear, side wall, ceiling or floor surface can be arranged, good measurement results. Likewise, an arrangement of the sensor (3) in or on a condensate collector is also (8) or in the evaporator dish a sensible place to arrange the sensor. A small change in the interior, being between the condensate collector (8) and a drip rail (6) is arranged on the rear wall evaporator (7), creates a place for one Particularly reliable measurement value acquisition of the sensor (3). It is advisable to use the sensor (3) to be arranged at the lower end of this drip tray (6).
- the senor (3) can be replaced.
- biochemical sensors should be interchangeable be, because after a certain period of use, depending on the design, exhaust itself.
- An example of a replaceable sensor is training in Shape of a chip.
- automatic or manually adjustable cleaning of a sensor is useful and, for example, through a brief reversal of potential or increase in potential reachable.
- the evaluation electronics (4) are preferably in the electronics already present in the cooling device (1) integrated or arranged in their vicinity. You (4) can also in another place be housed separately.
- the display element (5) is preferably on the control panel, such as it is known for refrigerators and / or freezers, arranged or in the front area of the Integrated door (10).
- a control element (11) can also be arranged on the control panel, via which the measuring device (3, 4, 5) is switched off and on manually can be. Switching off should be carried out immediately after cleaning the inside of the cooling unit (1) for a defined period of time to prevent interference with cleaning agent residues be avoided. The measuring device (3, 4, 5) is then either automatic or manually switched on again.
- the warning signal is after a predetermined Time that can also be stored in the electronics (4) is interrupted and periodically again activated. This warning continues until the interior is cleaned is carried out or the warning signal has been switched off manually.
- the time out for warning purposes a new, current measurement value acquisition can be interrupted as long until the interior has actually been cleaned. But also is it is possible that the time between warnings is shorter than the distances between the individual current data acquisition. Since the germ load predominantly after advanced time gets bigger, i.e. also ever higher concentrations of metabolic products, such as e.g. Nitrite can also be recorded, a maximum possible concentration as a reference limit be stored in the evaluation electronics (4). When this limit is reached the warning signal can no longer be suspended.
- a continuous display is said to be the advanced one Germination to clarify a health hazard when eating the exclude stored food as far as possible.
- the user should also be given the option of collecting the measured values and / or can turn off a warning if he does not have such information is interested or may even feel bothered by it.
- the presence of germs can be measured alongside a measurement of one of the metabolites bacteria, yeasts and / or mold (such as nitrite concentration) directly by biochemical sensing of bacteria, yeast and / or mold or the like determine.
- sensors (3) can therefore be used, e.g. electrochemical or biochemical sensors.
- FIG. 2 shows a refrigerator (1) whose door (10) hinged on the side is open is shown.
- the inside of the door (10) contains storage options, in particular for narrow or high refrigerated goods.
- a further sensor (3) for measuring the contamination can be arranged on the inside of the door.
- the interior (2) is designed in accordance with the cooling device described in FIG. 1. Basically, the moisture on the evaporator collects in the interior (2) and condenses there, icy and melting again. It is therefore an ideal location for the placement of a sensor (3) in the gutter (8) or in the evaporator dish.
