Definitions

  • the present invention relates to a refrigerating appliance, in particular a household refrigerating appliance, with a machine room, a refrigerating machine which releases waste heat into the machine room, a blower for removing the waste heat from the machine room and a machine room temperature sensor.
  • An error message is displayed to the user of the device, and if he notices it, he must rectify the problem as soon as possible in order to avoid excessive heating of the storage compartment and damage to the refrigerated goods contained therein.
  • the time available to remedy the disturbance is very limited as the refrigeration compartment is no longer cooled after detection of the disturbance and is continuously approaching the ambient temperature.
  • the need for quick troubleshooting can put a user under unpleasant psychological pressure, and it can also lead to relatively high repair costs if an emergency service needs to be called at an inconvenient time, for example on festive days.
  • the object of the invention is therefore to provide a refrigeration device that gives a user more time to respond to a fault before damage to the refrigerated goods are to be expected.
  • the object is achieved by providing a control circuit with the engine room in a refrigerator with a machine room, a chiller which gives off waste heat in the machine room, a blower for dissipating the waste heat from the machine room and a machine room temperature sensor for detecting a temperature in the machine room.
  • Temperature sensor is connected to take the refrigerator out of service when the temperature detected by the engine room temperature sensor exceeds a first threshold and to put the refrigerator back into operation when the temperature falls below a second threshold.
  • the first limit of the temperature should be low enough to safely prevent overheating of engine room components.
  • the exact amount of this limit can be selected according to the temperature resistance of the materials installed in the engine room. Conveniently, the first limit is between 60 ° and 80 ° C; this allows the use of inexpensive, not necessarily high temperature resistant plastic materials in the engine room.
  • the second limit may be the same or lower than the first limit. On the one hand, it should be as far below the first limit value as possible, after a fall below the second limit has been detected to allow the longest possible and therefore energy-efficient operation of the chiller before the first limit is exceeded again. On the other hand, it must certainly be higher than the ambient temperature of the refrigerator, otherwise it can not be undershot.
  • the second limit value is therefore preferably higher than a maximum expected ambient temperature of the refrigeration device. An amount of the second limit between 35 ° and 50 0 C, in particular about 45 ° C is preferred.
  • control circuit may be connected to an ambient temperature sensor, which allows it to set the second limit as a function of the ambient temperature, for example by a predetermined difference amount higher than the ambient temperature.
  • control circuit may expediently be set up to cool only a first of the two storage compartments after the refrigeration machine has been restarted.
  • This limited cooling operation produces less waste heat than if the cooling of both compartments is maintained so that, under favorable circumstances, viable storage conditions can be maintained in the first compartment.
  • a user only needs to provide for another accommodation or an immediate consumption of the contents of the second storage compartment, since damage to the contents of the first compartment is not to be feared.
  • the first compartment cooled in the case of re-commissioning of the refrigerating machine is preferably the freezer compartment since it generally has the higher content or the contents of the refrigerated compartment are generally intended for immediate use anyway and its short-term use therefore raises fewer difficulties in an emergency.
  • the control circuit can be connected to a temperature sensor of the first compartment in order to cool the first compartment only if the temperature drops below the second limit value if the temperature detected by the temperature sensor of the first compartment exceeds a third limit value. Otherwise, both compartments can be cooled according to their cooling requirements.
  • the cooling of the freezer compartment can be delayed until it has warmed up to a suitably fixed temperature above its actual desired temperature, and during this time an emergency cooling of the normal refrigeration compartment is also maintained.
  • a suitable temperature for the third limit value can then, for example, be chosen such that it still allows storage of the frozen food for several weeks, while the actual nominal temperature of the freezer compartment is designed for storage of the refrigerated goods for several months.
  • control circuit may also be configured to resume the cooling of the second storage compartment when the temperature detected by the engine room temperature sensor falls below a fourth limit, which is lower than the second. If the overheating of the engine room is due to an actual failure of the fan, it is unlikely that this fourth limit will be undershot, since the chiller re-starts and heats the engine room even if it falls below the second limit. However, if the reason for the overheating is due to a temporary blockage of air exchange between the machine room and the environment, for example by a foreign object blocking an air opening, then by this provision, the regular cooling operation can be fully resumed once the blockage is removed, and damage to refrigerated goods by an unnecessary interruption of the cooling operation is excluded.
  • the refrigeration device has a signal generator for displaying a warning message after exceeding the first limit value.
  • the warning message should remain after the second limit has been exceeded and a third party intervention should be required to reset it.
  • This foreign intervention can be a simple and expedient way interrupting the power supply at least the control circuit, in the simplest case of the entire refrigeration device, such as by pulling the power plug. This way even a non-expert user can reset the warning message. This is particularly desirable when the warning message is not due to a persistent technical malfunction of the device but to a temporary external disturbance such as the above-mentioned blockage of air exchange and intervention by skilled personnel to restore the functionality of the device is not necessary.
  • control circuit is preferably connected to a digital memory module. This allows a simple and precise definition of the limits for each individual device by writing to the memory, wherein the values to be written into, for example, depending on a climatic zone in which the device is expected to be used, or a maximum expected ambient temperature can.
