Definitions

  • the invention relates to a household washing machine set up for drying with a tub as a drying room for laundry, with a condenser channel coupled in the lower region of the tub, which is essentially vertical from a flow of cooling water and in counterflow to that from the tub by means of a Process air suctioned through the condenser duct is flowed through, and with a heating duct connected to the pressure side of the blower and arranged above the suds container, the outlet opening of which opens into the suds container, and with a detergent inlet duct guided between the suds container and a detergent flushing device, through which fresh water also flows can be supplied to the tub via a solenoid valve, and finally with a tub drain arranged at the lowest point of the tub with pump and drainage channel.
  • washing machines which are also set up for drying, are known and customary.
  • drying times that can be achieved with the known machines are generally criticized as being too long, as a result of which the specific energy expenditure is also considerably greater in comparison with the corresponding values in a so-called solo dryer - a machine which is only set up to dry the laundry.
  • the hot air ducts cause difficulties in the interior of the machine housing with heat-sensitive components of control units.
  • the invention has for its object to reduce the previously mentioned difficulties to a technically manageable level, to improve the efficiency of the drying process and to shorten the drying times.
  • this object is achieved in that an auxiliary air duct is connected between the condenser duct and the blower, the suction opening of which is directed towards the upper interior of the machine housing, and in that the detergent supply duct opens at a location in the detergent dispenser, the free connection to the machine surrounding atmosphere.
  • the secondary air duct can extract the hot air that has accumulated in the upper part of the housing and direct it to the drying room via the heating duct. This significantly improves the efficiency of the drying process.
  • the extracted hot air is replaced from below by cooler indoor air so that heat-sensitive components can always be adequately cooled. In addition, of course, the better efficiency leads to shorter drying times.
  • the embodiment of the invention is recommended in that the outlet duct contains a riser pipe section inside the machine housing, in front of which there is a connection to the location of the detergent dispenser to which the detergent inflow duct is connected, such that liquor emerging from the connection from the riser pipe section flows into the detergent feed channel.
  • the condenser duct can be connected to the suction side of the blower via an intake duct which is guided essentially horizontally in the upper housing area in the vicinity of heat-sensitive components of a control device. Appropriate routing and shaping of the intake duct up to physical contact with the relevant components can achieve noteworthy additional cooling effects.
  • the arrangement according to the invention is in a washing machine with a front loading opening, which is opened through a porthole door with a transparent pot window sealable and bounded by a sleeve between the opening in the housing and the opening in the tub, expediently such that the outlet opening of the heating channel via a channel section (sleeve channel), which in the sleeve is directed approximately radially towards the pot window arranged in the loading opening is that the warm air flow flows from the window into the drying room.
  • the heated air can be led into the drying room in the shortest possible way.
  • the cuff channel also consists of a poorly heat-conducting material (for example rubber), so that its heat radiation is replaced by heat quantities which flow in very slowly.
  • a tub 2 is arranged as a drying room for the laundry, which is stored in a laundry drum, not shown, which is rotatably mounted horizontally in the tub.
  • a tub drain 3 with pump 4 and drain channel 5 is coupled.
  • a condenser channel 6 is coupled, which is acted upon essentially vertically by a cooling water flow from a cooling water nozzle 7, which can be fed via a solenoid valve 8 from the chewing water network, not shown.
  • the fan 10 draws the warm and moist process air through the condenser channel 6 and dehumidifies it by the cold cooling water flow.
  • the heating channel 11 On the pressure side of the blower 10 is the heating channel 11 is connected, which is equipped with electric radiators 12. The dried process air heats up again on these radiators and is passed via the cuff channel 13 into the receiving space of the porthole window 14 and out of the window 14 into the drying room.
  • the condensate is fed together with the cooling water to the lower region of the tub 2 and pumped out of the machine there via the tub drain 3.
  • a detergent dispenser 15 which in the present example contains a drawer guided in a housing.
  • a connecting line 16 is guided to this detergent dispenser housing from the upper end of the riser pipe section 17 of the outlet channel 5.
  • a detergent inlet channel 18 is coupled to the front end of the detergent dispenser housing and opens out on the left in the lower region of the tub.
  • the cross section of this connecting line 16 is kept small enough that only a small amount of the liquor conveyed through the drain channel 5 and the riser pipe section 17 can be fed back into the tub through the detergent dispenser housing and the detergent feed channel 18.
  • This small branched-off liquor flow also serves for the condensation of part of the process air, which is dehumidified via the detergent supply channel 18 and the detergent dispenser 15 (arrows 20) and escapes from the machine.
  • the main stream of the moist process air enters the condenser duct 6 and is dehumidified there.
  • An intake duct 22 adjoins the condenser duct and runs through the upper housing area from front to back.
  • the dehumidified and cooled process air (arrow 23) is fed to the blower 10.
  • a secondary air duct 24 is connected to the intake duct 22.
  • Pre-heated dry air is drawn in from the upper region of the machine housing (arrows 25) and added to the cooled and dehumidified process air 23 through this secondary air duct 24. This increases the amount of air and thus the amount of heat that can be transported by the air on the way from the blower to the exit of the drying room.
  • this process air flow divides (arrows 20 and 21), as a result of which the additional air quantity sucked in through the secondary air duct 24 can escape again through the detergent supply duct 18.
  • the arrangement according to the invention has the additional advantage that the heating duct 11 does not have to be insulated from heat losses in a space-consuming and costly manner.
  • the control device compartment (not designated in more detail) located in the upper housing area is not excessively heated without the thermal energy radiated from the heating duct remaining unused.
  • the cross sections of the detergent supply duct 18 and the condenser duct 6 can be matched to one another, so that the air flow in the secondary air duct 24 or in the detergent supply duct 18 is small compared to the flow in the condenser duct 6.
  • the condensation of the process air in the condenser duct 6 and in the detergent supply duct 18 also deposits fluff from the drying chamber. This is of particular importance for the secondary air escaping from the detergent supply channel 18.
  • the invention is not restricted to the exemplary embodiment shown. It can also be used in a washing machine whose laundry drum can be loaded on the jacket side, that is to say preferably from above.
  • the heating channel 11 cannot then be arranged directly above the tub, as in the exemplary embodiment shown. Instead, an arrangement in one of the two remaining corners of the room at the front or rear half above the tub is conceivable.
