Definitions

  • the invention relates to a household appliance, comprising a fan for moving air in an air flow channel in a flow direction, a first heat exchanger and a second heat exchanger, which are arranged in the air flow passage in succession with respect to the flow direction, a cleaning device for cleaning the first heat exchanger with cleaning liquid wherein at operated cleaning device and operated fan at least a portion of the cleaning liquid can be directed to the second heat exchanger, and a collecting container for dripping of the second heat exchanger cleaning liquid.
  • the invention also relates to a method for operating a household appliance with a fan for moving air in an air flow channel in a flow direction, with a first heat exchanger and a second heat exchanger, which are arranged in the air flow channel with respect to the flow direction behind one another, with a cleaning device for Cleaning the first heat exchanger with cleaning liquid, wherein at operated cleaning device and operated fan at least a portion of the cleaning liquid can be directed to the second heat exchanger, and with a collecting container for dripping of the second heat exchanger cleaning liquid.
  • the invention is particularly advantageously applicable to laundry drying equipment, in particular to circulating air laundry drying equipment.
  • the invention is particularly advantageous applicable to household appliances with heat pump.
  • Fig.1 shows a sketch of a heat pump tumble dryer 1 of the type in question.
  • This has a receiving space for laundry to be dried (o. Fig.), Here, for example, a horizontally rotatable laundry drum 2.
  • a drying process penetrates dry-warm process air P from a process air duct 3 as the air flow channel in the laundry drum 2 and sweeps over the laundry there.
  • the process air P absorbs moisture.
  • the now moist-warm process air P emerges from the laundry drum 2 again and is passed through the process air duct 3 to a first heat exchanger 4.
  • the first heat exchanger 4 cools the process air P, which condenses out.
  • a heat exchanger surface of the first heat exchanger 4 located in the process air duct 3 is covered by a moisture film from which drops of condensation water fall off and fall down, for example into a drip tray (not shown).
  • the Moisture film but also in the process air P located particles such as lint and hair on the heat exchanger surface, which remain there even after evaporation of the moisture film and can reduce the effectiveness of the first heat exchanger 4.
  • a cleaning device 5 may be used which cleans the heat exchanger surface of the first heat exchanger 4 with water W at high momentum as a cleaning agent.
  • the cleaning device 5 may, for example, have a nozzle in communication with a pump, which is directed onto the first heat exchanger 4.
  • the cleaning device 5 may have a downpipe communicating with a water reservoir that is to be opened in a targeted manner (not shown), so that water W discharged in the downpipe at high speed impinges on the first heat exchanger 4 from above.
  • the downpipe may be formed on the output side with a nozzle system to produce a wider water curtain.
  • the now drier process air P is led to a second heat exchanger 6, which heats the process air P again.
  • the first heat exchanger 4 and the second heat exchanger 6, so are arranged one behind the other in relation to the flow direction of the process air P.
  • the now dry-warm process air P is introduced through the process air duct 3 into the laundry drum 2.
  • the process air duct 3 thus forms a closed process air circuit with the laundry drum 2.
  • a fan or fan 7 may be provided for circulating the process air P in the process air circuit.
  • the first heat exchanger 4 acts as a condenser and the second heat exchanger 6 acts as a heater.
  • the first heat exchanger 4 and the second heat exchanger 6 are formed here as parts of a heat pump, which additionally has a drive in the form of a compressor 8 and an expansion valve 9. These components 4, 6, 8 and 9 are interconnected in the arrangement shown by refrigerant tubes 10 in which working fluid or refrigerant K circulates.
  • the operation of a heat pump is basically well known and need not be further elaborated here.
  • the first heat exchanger 4 serves as an evaporator and the second heat exchanger 6 as a condenser from the perspective of the heat pump.
  • the water W coming to the second heat exchanger 6 drips down therefrom into an e.g. upwardly open collecting container 11, which can also be referred to as a "boat".
  • the drainage of the water W from the collecting container 11 through a drain (not shown) can take place very slowly. Therefore, when cleaning the second heat exchanger 6 different error mechanisms occur: a) The amount of water used for rinsing the second heat exchanger 6 ("Spüligange” V réelle) is significantly greater than a volume of the collecting container 1, whereby it exceeds a maximum level Lmax to overflow Water W can come into the process air duct 3.
  • This introduction of water W in the process air duct 3 and thus also in the process air P is not desirable, since a rewetting of the laundry can take place. This, in turn, can lead to uneven drying results, deterioration of equipment performance or contamination on the laundry.
  • the second heat exchanger 6 may be arranged in a variant at least partially in the collecting container 11. As a result, the second heat exchanger 6 can at least partially be in the water W with increasing fill level L in the collecting container 11 in order to further improve a cleaning performance. In another variant, the second heat exchanger 6 is not in the collecting container 11th
  • the second heat exchanger 6 can be cleaned in a process independent of a process for cleaning the first heat exchanger 4.
  • the fan 7 can be operated and not operated to clean the first heat exchanger.
  • the cleaning of the second heat exchanger 6 can during a drying process or be carried out in a separate cleaning process.
  • approximately 50% of the water W directed onto the first heat exchanger 4 can be transferred or forwarded to the second heat exchanger 6.
  • a position of the fan 7 in the process air duct 3 is basically not limited.
  • the fan 7 except between the laundry drum 2 and the first heat exchanger 4, for example, between the second heat exchanger 6 and the laundry drum 2 may be arranged.
  • the operation of the fan 7 and the cleaning device 5 can be controlled by means of a control device 12.
  • a household appliance comprising a fan for moving air in an air flow channel in a flow direction, a first heat exchanger and a second heat exchanger, which are arranged one behind the other in the air flow channel with respect to the flow direction, a cleaning device for cleaning the first Heat exchanger with cleaning liquid, wherein at operated cleaning device and operated fan at least a portion of the cleaning liquid can be directed to the second heat exchanger, and a collecting container for dripping from the second heat exchanger cleaning liquid, wherein the fan is operable depending on a level of the collecting container.
  • This household appliance has the advantage that a carryover of cleaning liquid of the collecting container by the process air can thus be avoided in a simple manner and without a constructive redesign of existing household appliances.
  • the heat pump domestic appliance is a laundry drying apparatus and the air flow channel is a process air channel.
  • the clothes dryer may be a standalone tumble dryer or a washer dryer.
  • the process air duct can be a closed process air duct ("circulating air dryer") or an open process air duct (“exhaust air dryer”).
  • the household appliance has a heat pump
  • the first heat exchanger corresponds to an evaporator of the heat pump
  • the second heat exchanger corresponds to a condenser of the heat pump
  • the cleaning device may, for example, have a nozzle that can be pressurized with the cleaning fluid or a downpipe.
  • the cleaning fluid may be or have water.
  • the cleaning fluid may include or be fresh water and / or condensate.
  • the water may have additives, for example detergents.
  • the level corresponds to a corresponding volume of the cleaning agent in the collecting container, so that the object is also achieved in that the fan is operable depending on a volume of the cleaning agent present in the collecting container.
  • the fan is sustainable depending on the level of the collecting container. This can be achieved, for example, by a controlled stopping of a motor of the fan (hereinafter referred to as "process air motor” without limiting the generality).
  • process air motor a motor of the fan
  • the amount of cleaning fluid reaching the second heat exchanger can be set particularly easily, in particular reduced. This can be done via a simple adaptation of a flushing duration t réelle the second heat exchanger, which depends on a corresponding operation of the fan.
  • An outflow rate (dVout / dt) from the catch tank can be taken into account by replacing dV / dt with (dV / dt - dVout / dt).
  • the shutdown of the process air motor can be limited in time.
  • the fan is stalwart before an end of an operation of the cleaning device.
  • This is particularly advantageous when a downpipe for flushing or cleaning of the first heat exchanger is used, since the operating time is advantageously fixed by opening and closing a valve connected to a high water tank valve. A lower opening time of the valve would possibly be disadvantageously associated with a lower water pressure during cleaning. Also, there is the further advantage that in the period between stopping the fan and the end of the operation of the cleaning device, the first heat exchanger is cleaned.
  • the fan can be activated or started after a start of operation of the cleaning device.
  • the fan may be stopped or stopped from, with, or after completion of a dispensing of cleaning fluid from the purifier.
  • the operating time of the cleaning device can be adjusted to a desired operating period of the fan, in particular when using a cleaning device driven by a pump.
  • a ventilation performance or speed of the fan for adjusting the amount of flushing water V Tha conducted to the second heat exchanger can be varied, ie, dV / dt can be selectively varied or adjusted.
  • the fan is sustainable depending on a measured level of the collecting container.
  • a particularly accurate filling of the collecting container can be achieved.
  • the household appliance may be formed with at least one level sensor, e.g. a float with Hall sensor.
  • an influence of an altered runoff behavior can be taken into account.
  • the fan is sustainable depending on a calculated level of the collection container.
  • This embodiment is particularly inexpensive because it does not require a level sensor. Thereby, e.g. a predetermined purge rate dV / dt is used.
  • the fan is sustainable upon reaching a shutdown level of the collection container, which shutdown level is lower than a critical level.
  • the switch-off level can thus be in particular a level which is so far below the critical level that the residual cleaning liquid (for example water) does not reach the critical level or only just reaches it.
  • the critical level is a maximum level of the collection container.
  • the critical level is a level at which no detergent is pressed from the collecting container into the air flow channel when the fan is operated.
  • the object is also achieved by a method for operating a domestic appliance with a fan for moving air in an air flow channel in a flow direction, with a first heat exchanger and a second heat exchanger, which are arranged one behind the other in the air flow channel with respect to the flow direction, with a Cleaning device for cleaning the first heat exchanger with cleaning liquid, wherein at operated cleaning device and operated fan at least a portion of the cleaning liquid can be directed to the second heat exchanger, and with a collecting container for dripping from the second heat exchanger cleaning liquid, the fan operated depending on a level of the collecting container becomes.
  • the method can be designed analogously to the household appliance and has the same advantages.
  • Fig.2 shows simplified in three diagrams to a rinsing of a second heat exchanger - eg the second heat exchanger 6 of the heat pump tumble dryer 1, to which reference is made in the following - associated time courses.
  • An upper diagram shows a differential volume of water discharged by the cleaning device 5 over a time t.
  • the purifier 5 starts discharging water at a discharge rate dVabr / dt, where Vabr is a volume of the water discharged from the purifier 5.
  • Vabr is a volume of the water discharged from the purifier 5.
  • This can be implemented, for example, by opening a valve between a downpipe of the cleaning device 5 and a water tank of the cleaning device 5 arranged above it (not shown).
  • the lower diagram shows a time evolution of the filling level L resulting from the upper diagram and the middle diagram in the collecting container 11.
  • the collecting container 11 is empty and fills up by the water W dripping down from the second heat exchanger 6.
  • the collecting container 11 fills, since a filling rate of the water W is greater than its drainage rate.
  • shut-off level Lstop corresponds to an associated shut-off volume of the water in the collecting container 11, and the critical level Lkrit a critical volume of the water W.
  • the critical level Lkrit corresponds to a level L, from the water W can be abducted to a considerable extent with the process air P. This can occur at a high level L - in particular the maximum level Lmax.
  • the second heat exchanger 6 With filling collecting container 11 and thus with increasing level L, the second heat exchanger 6 can be at least partially in the water W. This is particularly the case when the second heat exchanger 6 is at least partially disposed in the collecting container. This can further improve an effect of the cleaning.
  • a number may include exactly the specified number as well as a usual tolerance range, as long as this is not explicitly excluded.
