Definitions

  • the invention relates to a display case for storing and / or displaying objects, the walls, the bottom and the lid construction of which surround the display case interior more or less airtight in order to protect these objects against dust and environmental influences of all kinds.
  • a display case for storing and / or displaying objects, the walls, the bottom and the lid construction of which surround the display case interior more or less airtight in order to protect these objects against dust and environmental influences of all kinds.
  • FR-A-1 153 408 also describes a shop window showcase in which a fan is provided either in the base or cover area to prevent the showcase interior from fogging up in the cold season.
  • the fan sucks (cold) ambient air through a dust filter. It is well known that fans cause noise, so this anti-fogging solution is acceptable in shop window displays, but e.g. is hardly possible for museum showcases. Even with small fans, there is considerable airflow, and the energy requirement causes non-negligible costs.
  • the invention is therefore based on the object of designing a display case in such a way that the objects located therein are protected from environmental influences with the least possible technical outlay and expense.
  • the display case should also be retrofittable and not tied to a fixed location.
  • the air inflow into the showcase takes place automatically due to the pressure increase in the environment via the filter devices at a ventilation point, which cause the air to no longer flow in through the seals of the largely sealed showcase area but through the filter in a cleaned manner.
  • the showcase releases the previously cleaned air from the inside back into the environment.
  • the necessary installations for such a self-breathing showcase are very inexpensive and easy to attach.
  • floor Ventilation nozzle are attached, a filter insert with an inlet valve located in front of it and an outlet valve being provided in the ventilation nozzle.
  • the showcase is forcedly ventilated according to claim 1 - again via the filter devices.
  • This forced ventilation uses a source in which the air is either compressed, compressed or ventilated before it is fed into the showcase.
  • a pump or fan device used for this purpose is set so that it keeps the interior of the showcase from the environment at a slight overpressure and only conveys very small air volumes which correspond to the volume of air "breathed" from the showcase in the event of a sharp drop or increase in air pressure per unit of time .
  • the source therefore conveys only the smallest amount of air that is necessary to supply a sufficient amount of cleaned air even with the strongest climatic fluctuations, so that no unpurified air can enter. Even with large showcases, simple, inexpensive and smooth-running small pumps are sufficient for this purpose, so that both the installation and the operating costs are extremely low.
  • the pumps can only be switched on when the external pressure rises, so that the filter in the positively ventilated showcase continues to be contaminated in favor of its service life is reduced.
  • the positively ventilated showcase according to the invention with the extremely low air throughput allows the possibility of inexpensive air conditioning and humidity control in the inside of the showcase by connecting the pump to a cooling unit or to a cooling unit in conjunction with a hygrostat. In this way, cleaning, drying and moisture control can be carried out simply and inexpensively without connection to an expensive air conditioning system for individual showcases.
  • a pressure monitoring device is also connected to the display case, the performance of the pump can be checked and adjusted via a corresponding control line. In addition, it is possible to indicate both a failure of the pump and an unauthorized entry into the showcase, which also leads to a sudden drop in pressure.
  • the self-breathing showcase 1 shown in longitudinal section in FIG. 1 with lighting box 2, showcase base 3 and transparent showcase body 4 made of glass or other transparent material has a ventilation point and a ventilation point (B or E).
  • the interior of the showcase body is largely sealed, for example, by means of profile seals.
  • the connection points can be glued, it being advantageous in any case to use materials with the same thermal expansion coefficient for the display case body 4.
  • sockets 5 and 6 are attached, a dust and / or gas protection filter 7 and an inlet diaphragm valve 8 being provided in the ventilation socket 5 and the U-shaped breather nozzle 6 having a corresponding outlet diaphragm valve 9 .
  • the ventilation nozzle 5 is designed so that inexpensive commercially available standard combination filters can be screwed or plugged onto the nozzle, so that the filter can be exchanged quickly and easily.
  • the attachment and type of filter are largely arbitrary.
  • a filter can also be provided on the top of the display case. It is also possible to dispense with the venting point.
  • the positively ventilated showcase 1 shown in Fig. 1 'with base 3, transparent showcase body 4 and lighting fixture 2 has a ventilation pump 10 which is attached under the bottom plate of the showcase body and protrudes into the base.
  • This pump is an inexpensive pump of low power, which is connected via a corresponding air line to a ventilation nozzle 5 'and via this, which in turn contains a dust and gas protection filter 7, pumps cleaned air into the interior of the display case.
  • the pump requires only a very low delivery rate, which is preferably set to the volume per unit of time that would flow into the display case on its own if the air pressure rose rapidly. Assuming a maximum air pressure increase of approximately 7 hectopascals, this would correspond to approximately 7 liters of air per hour for a display case with 1000 liters of air volume. A delivery volume of approx. 10 liters per hour would therefore be completely sufficient.
  • the pump always creates a slight overpressure in the interior of the showcase compared to the surroundings, so that dust and harmful gases do not enter the interior of the cabinet Showcase can reach and the air is supplied exclusively through the filter. On the other hand, the slight overpressure can also lead to discharges of the lining and decoration means of the interior of the showcase, which impair the showcase climate.
  • the pump 10 can be electrically connected to the same connection line as the other showcase installations, i.e. for example, their lighting device. Deviating from the solution shown, it is also possible to accommodate the pump in the lighting box or on the back of a non-free-standing showcase.
  • the pump can also be set up outside the showcase and only connected to it via a connecting hose. Because of the low power required, it is possible to force-ventilate several display cases with a single pump in such an arrangement.
  • a fan can also be used, or a storage container, which contains cleaned air or a neutral gas under high pressure, can be connected to the interior of the display case via a pressure reducing valve.
  • the positively ventilated display case according to the invention can advantageously be expanded to a display case with a controllable climate or dry climate.
  • a controllable climate or dry climate In order to create a special "dry" climate in the showcase that slows down the chemical reactions on metal objects, this is largely sealed.
  • a cooling unit is set up outside the showcase, to which air is supplied via a filter.
  • the cooled “dried” air is fed into the interior of the display case with the help of a pump and corresponding air supply lines. Warms up here the air back to room temperature, its relative humidity is extremely low, so that time-consuming conservation work on certain moisture-sensitive objects is completely eliminated.
  • the air can also be filtered after the pump. In any case, the pump and the freezer only have to perform very little.
  • the forced-ventilated display case according to the invention can be expanded with the aid of a hygrostat and a refrigerator to a display case with controlled air humidity.
  • cleaned air is supplied to a refrigerator through a gas and dust protection filter mounted on the side and passed through a vessel containing water in the refrigerator.
  • cleaned air is again supplied to the showcase via the hygrostat.
  • the hygrostat is located in a small measuring room, the humidity of which corresponds to that in the interior of the showcase. If the humidity is too high, the hygrostat switches the refrigerator on, and if it is too low, it switches it off accordingly.
  • the installation costs and the operating costs are extremely low because of the low air throughput. The pumping and cooling performance are again very low.
  • a pressure monitoring device in the form of a pressure sensor which emits a signal in the event of a sudden drop in pressure, can be connected to the showcase in order to determine if the pump of a forced-ventilated showcase with or without climate control has failed.
  • the pump should Keep the interior of the display case at a higher internal pressure so that the pressure monitoring device responds reliably if the pressure drops.
  • the pressure monitoring device preferably regulates its output via a control line provided to the ventilation pump, so that there is always a predetermined air pressure within the showcase space.
  • a pressure drop below a predetermined value is detected by the pressure monitoring device and passed on to a switching device connected to it, which triggers a visual or audible display, for example via a corresponding line provided in a control center, if the pump fails.
  • a switching device connected to it, which triggers a visual or audible display, for example via a corresponding line provided in a control center, if the pump fails.
  • the outside pressure can also be measured using a pressure sensor.
  • the measured value is fed to a control device which is connected to the pump or a fan device or also the valve of a storage container and which initiates the air supply through this device only when the external pressure rises.
  • a nitrogen or argon container is connected to the showcase via a mixing or pressure reducing valve and corresponding supply lines, these gases can be used for targeted conservation and pest control. If necessary, other gases or gaseous additives can also be added for this purpose.
