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.

  • the body 4 is intended to be mounted in a furniture recess, wherein a bottom of the furniture recess, not shown in the figure, has a central cutout through which the base unit 2 engages in a base region of the furniture receiving the device, directly above the floor level.
  • a grate with a plurality of through holes 6 is inserted into a base board 5 of the furniture. Behind the passage openings 6, a condenser 7, a blower 8 and a compressor 9 are housed in the machine room 1 in a conventional manner.
  • the fan 8 drives an air flow which enters the engine room 1 via part of the passage openings 6, passes the condenser 7 and the compressor 9 and exits via adjacent passage openings 6 and thus dissipates waste heat released by condenser 7 and compressor 9.

  • step S1 shows a flowchart of a process executed by the control circuit 11 in the event of a heat removal from the engine room 1.
  • the engine room temperature Ts requested by the temperature sensor 12 in step S1 is compared with the above-mentioned upper limit value Tso in step S2. If the limit is not exceeded, a fault flag Tsflag is interrogated in step S3, which will be explained in more detail later. If the malfunction flag Tsflag is not set, the control circuit 1 1 proceeds to the normal operation described above in step S4.
  • step S2 If exceeding the limit value Tso is detected in step S2, the failure flag Tsflag is set in step S5.
  • a warning signal is output in step S6, for example by setting an optical signal on the control panel 10 or starting an acoustic signal generator.
  • step S7 the compressor 9 is taken out of service to prevent further heating of the engine room 1. Then, the process returns to step S1.
  • step S1 the temperature Ts in the engine room is measured again. If, after the compressor is turned off in step S7 and the elapse of a certain period of time, the engine room has cooled below the threshold Tso again, the process returns to step S3. Now that the failure flag Tsflag is set, the process branches to step S8, where the engine room temperature Ts is compared with a second, lower limit Tsu.
  • the second limit value can be fixed by its value is entered in a nonvolatile memory of the control circuit. This value can be set differently by the manufacturer of the device in different devices of a series, depending on the climate zone in which a device is intended for use.
  • a value can always be selected which, on the one hand, is as low as possible, but on the other hand, with sufficient certainty, is higher than the ambient temperature of the device.
  • the limit value Tsu can also be variable.
  • the control circuit 11 may be connected to an ambient temperature sensor (not shown) to select (among others) the threshold value Tsu by a predetermined differential amount higher than the ambient temperature. If the threshold value Tsu is not fallen below in step S8, the process returns to step S1; in the other case, it goes to step S4.
  • step S4 as in the normal uninterrupted operation of the apparatus, based on the temperature detected by the sensor 13, it is decided whether the compressor 9 is turned on or not, and the compressor is switched according to the decision. Thereafter, the process again returns to step S1, so that when the restart of the compressor again results in an increase of the engine room temperature Ts above the threshold Tso, the compressor is again turned off regardless of the refrigerator compartment temperature.
  • the compressor 9 continues to operate intermittently, although the ratio of switch-on and switch-off times of the compressor 9 rather than the temperatures in the compartments is determined primarily by the engine room temperature Ts: by alternating steps S4 and S7 , the compressor is operated as much as possible without causing critical overheating of the machine room 1, which could affect the components mounted therein.
  • Fig. 3 shows a further development of the method of Fig. 2, which is applicable in a combination refrigerator having at least two different, held at different desired temperatures storage compartments, each associated with a temperature sensor.

  • the process steps S1 to S3 and S5 to S8 are the same as described with reference to FIG.
  • the step 4 differs from that of the refrigeration device in Fig. 1 only in that the compressor 9 is always switched on when the temperature sensor of one of the compartments detects a temperature above the nominal temperature interval assigned to this compartment, and it is switched off again when the temperature in this compartment has reached the lower limit of the set temperature interval ,

  • the compressor 9 no longer cools the normal refrigeration compartment, the average heat output by compressor 9 and condenser 7 is reduced, and comparatively long periods of compressor operation are possible before renewed exceeding of threshold Tso in engine room 1 causes a further emergency shutdown S7 of the compressor forces.
  • the heat release with exclusive cooling of the freezer compartment is so low that it does not exceed the limit value Tso. That is, although the normal refrigeration compartment is no longer cooled, but the freezer compartment can be maintained at its desired temperature despite the disturbance, so that damage to its contents is not to be feared even with prolonged stopping of the disturbance.
  • Steps S1 to S9 are the same as in the method of Fig. 3; a difference is that between steps S8 and S9, as an additional step S10, a check is made for the temperature Tpr of the prioritized compartment.
  • step S4 If it is below a threshold temperature Tgr, and the prioritized compartment therefore does not necessarily have to be cooled, the process branches to normal operation of step S4, that is, the control circuit 1 1 monitors the temperature in both compartments and cools each compartment if there is a need for cooling is detected. Only if the exceeding of the threshold value Tgr in the prioritized compartment is determined in step S10, the attempt to also cool the non-prioritized compartment is abandoned, and the cooling is restricted to the prioritized compartment.

  • the target temperature is typically at about -18 ° C
  • the limit value Tgr may be suitably selected in a range of -16 ° to -10 0 C.

  • a further step S11 is inserted between steps S10 and S9, in which the engine room temperature Ts is compared with an upper limit for the normal operation Tsn which is significantly lower than Tsu. In the event of a malfunction of the blower 8, this limit value is never exceeded, as already falls below the limit Tsu the compressor goes back into operation and the temperature Ts of the engine room rises again.
