Definitions

  • the invention relates to a dry cleaning device with a washing drum, which is rotatably mounted in a surrounding housing, with a feed line for the solvent and an outlet line in the lower region of the housing, with lines connected to the housing and a fan for circulating the drying air after the completion of the Washing and draining the solvent and with an air cooler to condense the solvent vapors carried by the drying air and an air heater to heat the returned drying air.
  • a disadvantage of such known dry cleaning devices is that the heat extracted by the refrigeration machine to condense the solvent vapors of the drying air occurs again at the condenser and has to be removed by air or water cooling and is lost. On the other hand, heat must be supplied to the drying air by superheated steam or electrical energy for renewed heating in the air heater.
  • the object of the invention is therefore, in a dry cleaning device of the type mentioned, to make the heat extracted from the drying air for condensation of the solvent vapors entrained by the drying air reusable before being blown into the washing drum.
  • this object is at a T rockentivs- of the initially indicated type of apparatus achieved in that the air cooler are formed through the evaporator and the air heater through the condenser of a heat pump.
  • the heat pump removes heat from the circulating drying air for the condensation of the solvent vapors, which heat is returned to the drying air circuit before the drying air is blown into the washing drum. This not only saves energy, but also simplifies the structure of the dry cleaning device, because only a heat pump is required to cool and then reheat the drying air.
  • the refrigerant vapor compressed by the compressor or the liquefied refrigerant can be fed to the evaporator via an expandable valve via an expansion valve. Because in order to avoid overheating of the goods, it may be necessary not to release the condensation heat of the refrigerant completely into the drying air through the condenser designed as an air heater, but rather through the switchable condenser. The release of condensation heat by the switchable condenser can also be necessary because the compressor of the heat pump emits additional heat to the refrigerant.
  • the washing drum 2 is rotatably mounted in a drum-shaped housing 1.
  • the goods 3 that can be inserted through flaps (not shown) are also dried.
  • the solvent introduced into the housing 1 is drawn off through the line 4 after the cleaning process, while the overflow line 5 ensures that the solvent level does not exceed the predetermined level.
  • Air is drawn in from housing 1 by fan 6 through suction line 7.
  • the suctioned drying air enters the fan 6 via the lint filter 8 and is split behind it by the adjustable flap 9 into two partial streams 10, 10 '.
  • the partial flow 10 ' is passed through the air cooler 11, which is formed by the evaporator of a heat pump.
  • the partial flow 10 ′ of the drying air is cooled to such an extent that the condensed-out solvent collects in the funnel-shaped bottom of the cooling chamber 12 and is drawn off through the only dash-dotted line 13.
  • the partial flows 10, 10 reunite and pass together through the air heater 14, which is by the Condenser of the heat pump is formed.
  • the heated drying air re-enters the housing 1 through the blowing line 15 and removes the solvent adhering to it by evaporation of the goods.
  • the housing 1, the suction line 7, the cooling chamber 12, the bypass line for the partial flow 10, the overheating chamber 14 and the injection line 15 form a closed system.
  • the heat pump consists of the compressor 16, which compresses the sucked-in refrigerant vapor, so that the refrigerant liquefies again by increasing its boiling point in the condenser 14 and releases its heat of condensation to the drying air.
  • the liquefied refrigerant is then passed through a line (not shown) into the storage container 17 for the refrigerant.
  • the refrigerant passes through a filter 18, a sight glass 19 and a solenoid valve 20 to the expansion valve 21, through which the refrigerant is throttled and injected into the evaporator 11 after expansion.
  • the refrigerant extracts its heat of vaporization from the partial flow 10 ′ of the drying air.
  • the additional condenser 23 can be switched on by the pressure switch P 1 , via which the liquefied refrigerant then flows back into the storage container 17.
  • the additional condenser 23 is switched on when the pressure in the refrigerant rises too far on the pressure side. This is necessary because not only the heat of vaporization absorbed in the air cooler, but also heat converted from the mechanical work of the compressor 16 is supplied to the refrigerant.
  • the additional capacitor 23 is also switched on when the temperature set on the drying thermostat 24 the drying air is reached. At this time, the bypass valve 25 opens and the heat is only dissipated through the additional condenser 3. Overheating of the goods 3 is thereby avoided.
  • a safety push-button switch 26 is provided, which switches off the heat pump and the drying device in the event of a fault.
  • the working pressure switch 27 switches the compressor 16 on and off depending on the suction pressure.
  • the temperatures required to liquefy the solvent on the air cooler 11 are also set on this working pressure switch 27.
  • the device shown schematically in FIG. 2 differs from the device according to FIG. 1 in that the drying air is drawn out of the housing 1 through a suction line 28 connected to its lower region. Furthermore, the connecting line 29 is designed to rise from the air cooler 11 to the air heater 14. This configuration ensures that, in the event of the system being switched off, no air containing solvent can get back into the washing drum from the lines carrying the drying air. In the embodiment according to FIG. 2, flaps 30, 31 closing the air lines can therefore be dispensed with.
