Definitions

  • the invention relates to a heat pump operated drying chamber, which comprises a first chamber part for goods to be dried, a second chamber part for the heat pump equipment including components and a rotatable drum placed in the first chamber part.
  • drying cabinet drums in which the dampness from the goods to be dried in it and also the dampness, which gets off along with the circulating air flow from the cabinet, is condensed in a colder surface arranged in the process and removed as water. Then the dried air flow is heated and blasted anew to the goods to be dried.
  • the cold surface is either a surface kept in room temperature or, for instance, a water cooled surface and heating of air is brought about by means of electric resistances, for instance, publications EP-1146161 and GB- 2002891 .
  • the heat pump operated drying chamber according to the invention is characterized in that the drying drum placed in the drying part, can be easily installed and removed, as let down on rolls mounted in the chamber part, and the drying air is conducted in the drying drum through a free opening arranged in the end of the drum and off the drum through openings in the other end of the drum.
  • the drying chamber can be made larger for hang up of full-size garments.
  • the relatively lightly constructed detachable drum of plastic can be used as laundry basket into which laundry is collected before moving into the washing machine. Into it can also washed and centrifuged laundry in turn be collected and it can be lifted with the laundry into the drying chamber.
  • the drum is easily lifted into the chamber onto rolls in the chamber, so it can be lifted also with the laundry, or instance, with 10 kg in the drum.
  • the wear of textiles is minimal compared with traditional drying drums.
  • the power consumption of the turning motor is then also very small.
  • the advantage of the chamber is that at the same time with the drum drying can in the chamber upper part for drum drying unsuitable textiles be dried, which need, for instance, hanging up.
  • FIG. 1 shows a drying chamber comprising a first chamber part 1 in the in the upper part of the construction and a second chamber part 2 in the in the lower part of the construction forrning the socket part.
  • the first chamber has a rotatable drying drum 8, which is installed to be rolling on rolls I3. one roll 13 is at least is connected to the motor and driving. There is in drum 17 a free opening forwards for placing and removing laundry.
  • a compressor 3 In the lower part socket 2 there a compressor 3, a cooling radiator 4, heating radiator 6 and necessary components and adjusting means of the heat pump.
  • the lower part has at least one air circulation blast 6, by means of which over the radiators 4 and 5o f the lower part the air is conducted to the chamber upper part 1.
  • the air is at first circulated to cooling radiator 4, then to heating radiator 5.
  • There is in the lower part also a water-collecting vessel 10.
  • Figure 2 shows the drying chamber from one side, whereby the conduction of air circulation from the lower part socket 2 to the cabinet upper part 1 is clarified.
  • the partition wall 7 separates the lower socket 2 air space from the air space of the chamber upper part 1.
  • the circulation air is conducted as per figure 1 from the lower part output 15 according to the capsular door construction 9 so that the door construction works as air channel till the flow in the door has got up to the free opening 17 of the drum.
  • Figure 3 shows a drying chamber with drum 8 removed.
  • the air tubes 6 for drying of footwear are lifted up, whereby through them the air flow reaches the footwear, after the valve in the point of the folded tube has got open.
  • the drum is removed, in the chamber upper part full sized garments 20 can be placed by means of a coat hangers.
  • Figure 4 shows as example how air comes to drying tube 16 from tube 12 that comes from lower socket 2, when the tube is turned upwards. When the tube is turned to horizontal ,air cannot get from tube 12 into tube 16.
  • the rotation of drum can be intermittent including dead times.
  • the direction of drum is changed in occasionally, which activates the motion of laundry in the drum, because the rotation is quite slow, under 20 rotations per minute, possible less than 10 rotations, and in occasionally, the drum is even stopped.
  • the above presented way of rotation handles the laundry very carefully and is clearly better than the earlier ways of pump drying ways. Drying by means of heat pump keeps temperature in the chamber relative low for instance, about 30°C. The blast air is, however, in that temperature very dry, so the drying is very effective.
  • Due to the low working temperature drum 8 can be made of plastic, for instance, with rotational mold casting, which is an advantageous way of manufacture. The drum keeps well its form in the temperatures in the device.
