Definitions

  • the invention relates to a domestic appliance for the care of laundry, with a drum for receiving the laundry items, and a process air, through which process air to and through the drum is conductive, a lint filter, which in the flow direction of the process air to the drum and for filtering in the Flux disposed process air is arranged, and a sensor for detecting at least one parameter of the process air. Furthermore, the invention relates to a method for removing lint from a domestic appliance for the care of laundry items.
  • US 2007/0107250 A1 and WO 2007/057260 A1 is in each case a domestic appliance for the care of laundry items, in particular a tumble dryer, known, with a drum for receiving the laundry items and a process air duct through which process air to and through the drum can be conducted, and a lint filter, which in the flow direction of the process air after the drum and is arranged to filter the lint contained in the process air.
  • a sensor as mentioned above is explicitly confirmed in any of these documents.
  • the use of sensors in particular to temperature measurements in a tumble dryer is common.
  • a tumble dryer sensor comprising at least one sensor to monitor the drying process can.
  • a sensor is used in particular in the process air stream, which is designed for example for determining temperature and humidity in the process air stream.
  • Such a sensor must maintain its function over the entire service life, since the sensor must guarantee the device safety as well as optimum process control.
  • a lint filter is used in a tumble dryer, which is provided for filtering out the lint contained in the process air flow to the drum and which can be removed from the domestic appliance for removing the collected lint from a user.
  • a sensor is used in an area of the tumble dryer in which it comes in contact with the process air flow.
  • the lint is removed as far as possible by the lint filter, but still remain ultra-fine in the system that can pass through the lint filter or bypasses and then possibly attach to the sensor.
  • Flow obstacles in particular, as well as areas with a delayed flow velocity, in this context form possibilities for settling the non-filtered lint.
  • lint can thus also be deposited on appropriately positioned sensors, even if they are arranged behind the lint filter in the flow direction.
  • the functionality of a sensor can be impaired; For example, a function-relevant time constant increases, or the sensitive surface, in particular of a humidity sensor, is added.
  • An inventive household appliance for the care of laundry comprises a drum for receiving the laundry items.
  • the domestic appliance has a process air duct through which process air can be conducted to the drum and through the drum.
  • the domestic appliance has a lint filter, which is arranged downstream of the drum in the flow direction of the process air and is designed to filter the lint contained in the process air.
  • the domestic appliance comprises at least one sensor for detecting at least one parameter of the process air, which is thus arranged in particular so that it comes into contact with the process air and thereby can attach fluff located in the process air flow to this sensor.
  • the lint filter and the sensor are arranged in the domestic appliance such that lint accumulated on the sensor can be automatically removed by the lint filter when the lint filter is removed from its installed position in the domestic appliance.
  • a construction is created in which the removal of adhering to the sensor lint can be done easily and reliably.
  • the position of the lint filter and the sensor in the device is selected so that the leakage of the sensor is almost automatically carried out when the lint filter is removed from the device. It can also be achieved that regardless of the accessibility of the sensor this no longer needs to be cleaned separately, but is virtually automatically cleaned when removing the lint filter.
  • the senor is always cleaned even when the lint filter is removed for cleaning from the domestic appliance.
  • the cleaning of the sensor can not be forgotten or overlooked.
  • the permanently reliable and correct functionality of the sensor can be ensured thereby and unwanted excessive linting can be prevented.
  • the senor can thus be installed in the home appliance so that it no longer necessarily be fully accessible for direct cleaning, but it is sufficient that it is positioned to the lint filter so that when it is removed, the automatic cleaning of lint from the sensor can be done.
  • the lint filter on the removal path from the domestic appliance passes by the sensor and the lint can be stripped off at the sensor.
  • This is a particularly simple embodiment of the cleaning of the sensor, since no further complex components are required in this regard.
  • an undesired force on this can be prevented by a simple pass by the sensor and thus also possible damage to the sensor can be avoided.
  • the priority of the stripping thus allows a particularly gentle yet effective removal of the lint from the sensor.
  • the lint filter has a stripping device formed on the sensor to remove the lint. It is thus provided that the lint filter is specifically designed so that it can remove the fluff particularly effectively and also gently from the sensor during removal.
  • the wiper device to be removed from the sensor is fixedly arranged on the lint filter, in particular integrated on the lint filter.
  • an integral configuration with the lint filter may be provided.
  • a mechanically stable lint filter can be created with the stripping and a simple production and thus a cost-effective production can be realized.
  • the stripping device has a brush-like part, which is designed to remove the lint from the sensor and to collect these lint.
  • the brush-like part is designed so that after removing the lint from the sensor, the lint is automatically collected and thus automatically removed with the lint filter from the household appliance. It can thereby be avoided that the flakes stripped off by the sensor are undesirably distributed in the process air duct and can deposit there again at other components or can no longer be removed.
  • the wiping device in addition to the automatic removal of the lint from the sensor, automatic disposal from the household appliance is also ensured.
  • the domestic appliance is designed as a dryer.
  • the dryer is designed as a condensation dryer and has a closed process air guide.
  • the dryer is realized as an exhaust air dryer and has an open process air guide.
  • process air is conducted by means of a process air duct to and through a drum in which the items to be treated are contained.
  • the lint contained in the process air after leaving the drum are filtered out of the process air by a lint filter.
  • Values of at least one parameter of the process air are detected by a sensor of the household appliance. Fluff accumulated on the sensor will be removed from its installed position when the lint filter is removed automatically removed by the lint filter.
  • a highly efficient method of removing lint adhered to a sensor can be provided.
  • the cleaning of the sensor is carried out at the same time.
  • An independent independent cleaning step of the sensor is no longer required. This ensures the permanent cleaning of the sensor and does not forget to clean the sensor or only at irregular intervals.
  • the functionality of the sensor can be improved and thus the entire reliable functionality of the household appliance can be permanently guaranteed.
  • the removal path of the lint filter from the domestic appliance is conceptually predetermined so that the lint filter passes by the sensor and the lint is stripped off the sensor. It is specified space-specific and construction-specific thus, as the lint filter is removed from the domestic appliance and thereby automatically cleans the sensor of the lint. This guided removal can avoid that a user removes the lint filter on a path which would ensure no or only a very inadequate cleaning of the sensor. If the removal path can not be structurally carried out differently and is conceptually specified, this ensures the reliable and effective cleaning of the sensor.
  • the lint is removed from the sensor by a wiper device arranged on the lint filter.
  • the lint filter is thus technically designed so specific that it includes a specially designed stripping device at a defined location, which ensures the lint removal from the sensor particularly well.
  • the lint is preferably stripped from the sensor by the wiper and automatically collected for removal from the domestic appliance by the wiper. A stripping of the lint from the sensor and a falling of these stripped lint into the process air flow can be avoided. The deposition of the stripped lint in inaccessible areas of the process air duct can be prevented. Also, it is no longer necessary that the lint removed from the sensor must be removed from the process air supply or the household appliance by a further separate disposal step. With the Stripping the lint from the sensor, the device is also designed so that on the other removal path and the lint automatically remain on the stripping and are taken out with. A low-effort and hygienic disposal is thus guaranteed.
  • the dryer 1 is shown as a condensation dryer, but the dryer 1 can also be designed as a vented dryer.
  • the dryer 1 comprises a drum 2 for receiving laundry items to be dried, which is rotatably mounted about a horizontal axis 3.
  • the drum 2 On the front side, the drum 2 has a charging opening 4, which can be closed by a door 5.
  • the dryer 1 further comprises a closed process air duct 6 through which process air is circulated.
  • the process air duct 6 comprises a duct system with a falling section 7, which represents the front area of the air duct.
  • the process air guide 6 comprises a subsequent to the falling portion 7 horizontal portion 8, which then merges into a rising portion 9 and then opens into the drum 2.
  • the dryer 1 further comprises a heat exchanger 10, which is coupled in the embodiment in the horizontal section 8 with the process air guide 6 and arranged in this.
  • the heat exchanger 10 may be a simple countercurrent or crossflow heat exchanger.
  • the dryer 1 has a heat pump, which is an evaporator and a condenser includes.
  • the evaporator and the condenser are connected via a line system in which a compressor and a throttle is arranged.
  • a working fluid in particular a refrigerant
  • the heat pump can be designed according to the principle of the compressor heat pump, but can also work on the principle of Peltier heat pump.
  • a dryer 1 equipped with a heat pump
  • the cooling of the warm, moisture-laden process air exiting the drum 2 takes place essentially in the evaporator of the heat pump, where the heat transferred is used to evaporate a refrigerant used in the heat pump cycle.
  • the heat-evaporated refrigerant of the heat pump is supplied via a compressor to the condenser of the heat pump, where due to the condensation of the gaseous refrigerant heat is released, which is used to heat the process air before entering the drum 2.
  • the refrigerant circulates in the mentioned closed circuit in which it passes from the condenser via a throttle back to the evaporator.
  • a blower 11 is provided, which is arranged in the embodiment in the flow direction of the process air in front of the drum 2 and connected to the process air duct 6 and coupled thereto.
  • the fan 11 thus acts as a pressing system.
  • the fan 11 is arranged in the flow direction downstream of the drum 2, for example in the falling section 7, and thus is designed as a sucking system.
  • the dryer 1 further comprises a heating device 12, which is arranged in front of the drum 2.
  • the heater 12 is thermodynamically coupled to the process air and warms them up before entering the drum 2.
  • the dryer 1 comprises a lint filter 13, which is arranged in the falling section 7.
  • the lint filter 13 is arranged in front of a sensor 14 in the flow direction of the process air in the exemplary embodiment.
  • the sensor 14 is for detecting at least one parameter of the process air, for example the temperature and / or the Moisture formed. It can also be provided that the sensor 14 is arranged in the flow direction of the process air in the process air duct 6 in front of the lint filter 13.
  • the lint filter 13 comprises a stripping device 15, which is fixedly arranged on the lint filter 13, in particular integrally formed therewith.
  • the scraping device 15 preferably comprises a brush-like part which is designed to strip and automatically collect the lint accumulated on the sensor 14.
  • the lint filter 13 is positioned with the stripping device 15 in the dryer 1, that it is guided past the sensor 14 during removal and stripped by the Vorbeicomb on the removal path adhering to the sensor 14 lint through the stripping device 15 and automatically be collected and disposed of by the further removal of the lint filter 13 and automatically from the dryer 1.
  • the guide for forming the removal path of the lint filter 13 from the domestic appliance or the dryer 1 is designed so that a user has specified only this one removal path and thus automatically the lint filter 13 past the sensor 14.
  • the accessibility and the removal of the lint filter 13 are relatively simple and low effort and it is irrelevant to the user whether the accessibility of the sensor 14 is provided accordingly, since this is irrelevant to the user due to the automatic cleaning and removal of the lint filter 13.
  • the sensor 14 can thus also be arranged on a region of the dryer 1 that is relatively inaccessible to a user, it is essential that the arrangement be such that the sensor 14 is automatically cleaned of lint on the removal path of the lint filter 13. For this purpose, it is advantageous that the lint filter 13 and the sensor 14 are arranged relatively adjacent to each other.
  • the lint filter 13 is removed, and thus any intended cleaning of the lint filter of lint collected therein, the sensor 14 is also automatically cleaned.
  • the always reliable cleaning of the sensor 14 can be ensured and, moreover, the forgetting of the cleaning of the sensor 14 can be avoided.
  • FIGS. 2a ff. Can be seen in an embodiment, such as pulling out a lint filter 13 from a process air duct 6 a on the Lint filter 13 attached scraper 15 a sensor 14 in the process air duct 6 cleans.
  • the FIGS. 2a to 2d show an embodiment of a process air duct 6 with an upper-side inflow, in the vicinity of the door 5 (see Fig. 1 ) and in which the process air after passing through the drum 2 (see. Fig. 1 ) flows in from top to bottom.
  • FIG. 2a shows the lint filter 13, as it must be placed in the process air guide 6 during operation of the dryer 1.
  • the lint filter 13 has under a top-side inflow V-shaped arranged ribs, which carry a not shown in the figures sieve or network for collecting the entrained by the process air lint. These ribs end in a lower-side arrangement of two strips, which are connected via a non-visible Bares film hinge.
  • one side of the lint filter 13 can be opened in order to be able to remove the lint that has accumulated in the interior of the V-shaped structure formed by the ribs and the sieve or net located thereon, after removing the lint filter 13 from the process air guide 6 , How this removal happens, the show FIGS. 2b to 2d ,
  • the lint filter 13 On the underside, the lint filter 13 carries a scraper 15 in the form of a brush, said scraper 15 is below a arranged in the process air duct 6 sensor 14, for example, a temperature sensor, when the lint filter 13 is in the operationally necessary position according to FIG. 2a located. If the lint filter 13 is now removed from the process air guide 6, as is the sequence of FIGS. 2b to 2d shows, the scraper 15 touches on the sensor 14 along or over and thus cleans it of fine lint that has not caught the lint filter 13 and have been deposited on the sensor 14. By the step of removing the lint filter 123, the cleaning of the sensor 14 is performed at the same time.
  • a special, independent independent cleaning step for the sensor 14 is no longer necessary. As a result, the permanent cleaning of the sensor 14 can be ensured and the cleaning of the sensor 14 can not be forgotten or only performed at irregular intervals. The functionality of the sensor 14 is thereby significantly improved, thereby ensuring the entire reliable functionality of the household appliance permanently.
