Definitions

  • the invention relates to a tumble dryer with a drying chamber for the objects to be dried, a process air duct, in which there is a heater for heating the process air and the heated process air can be guided by means of a blower over the objects to be dried, and at least a first lint filter, and a procedure for its operation.
  • the lint filter is formed as a double filter with a coarse and a fine filter, wherein the coarse filter is designed as a flat filter, which is followed by a depth filter in the direction of the flowing process air as a fine filter.
  • the lint filter is arranged in a support frame, which is in particular in two parts and foldable.
  • drying air In a tumble dryer, hereinafter also abbreviated to "dryer”, air, commonly also called “process air”, is passed through a fan via a heater in a wet laundry containing drum as a drying chamber. The hot air absorbs moisture from the laundry to be dried.
  • the now moist and warm process air is passed in a condensation dryer in a heat exchanger, which is usually preceded by a lint filter.
  • the moist process air is cooled so that the water contained in it condenses.
  • the condensed water is separated from the process air and then generally collected in a suitable container for later disposal, and the cooled and dried air is returned to the heater and then to the drum.
  • a lint filter in particular lint filter, not only has the task of preventing the contamination and possibly narrowing of the process air duct over the life of the dryer due to the lint.
  • the lint filter serves to prevent a lowering of the efficiency of the heat exchanger due to linting on its surfaces.
  • the latter task can fulfill a conventional lint filter but only imperfectly, since in a dryer usually not only lint incurred, which can catch a filter in the form of a sieve. Rather, the entirety of the fluff comprises so-called ultra-fine fluff, which are lint in the form of a fine dust, which can not be collected by a conventional sieve and which thus in particular can get into the heat exchanger and settle there. The purification or occasional cleaning of the heat exchanger is therefore of great importance for the efficient operation of a dryer.
  • the drying process in a dryer is energy-intensive, since the heat extracted by means of cooling air during cooling of the process air in the heat exchanger is energetically lost to the process when this heat is dissipated in the cooling air. By using a heat pump, this energy loss can be significantly reduced.
  • the cooling of the warm, moisture-laden process air essentially takes place in a first heat exchanger of the heat pump, in particular an evaporator, where the heat transferred is used to evaporate a refrigerant used in the heat pump.
  • Such refrigerant vaporized due to the heating is supplied via a compressor to a second heat exchanger of the heat pump, in particular a condenser, where due to the condensation of the gaseous refrigerant heat is released, which is used to heat the process air before entering the drum.
  • the liquefied refrigerant passes through a throttle, which reduces its pressure, back to the evaporator to evaporate there, with renewed absorption of heat from the process air.
  • a heat transfer takes place at several points during the passage through the heat pump. Flue clean heat exchanger surfaces are therefore of great importance when using a heat pump.
  • a heat pump is generally so integrated into the dryer because of its construction that it can not be removed from the dryer to clean lint.
  • fluff should be collected and removed before entering a heat exchanger.
  • it makes sense to protect certain sensitive components such as heating and / or heat exchanger in a dryer with heat pump in particular against ultra-fine. It is difficult that an ordinary sieve-like lint filter is only suitable for capturing fine dust.
  • a lint filter For collecting and removing lint is generally in a process air duct behind the drying chamber of a dryer, a lint filter.
  • the lint When using a lint filter, the lint will stick in a fine mesh screen and be mechanically removed by the user after drying.
  • Finer lint, in particular ultrafine lint can pass through the lint filter and deposit at other points in the process air duct and hinder the heat exchange in a downstream heat exchanger.
  • EP 0 477 554 B1 describes a tumble dryer in which the heat exchanger streamed by the process air flow is exposed to a drying chamber in spite of the lint filter, which absorbs a large part of the lint produced during a drying process.
  • the lint which is not collected by the lint filter due to its small size, separates with condensing water vapor mainly in the inflow region of the heat exchanger and gradually forms a felt which hinders the process air flow and degrades the heat transfer in the heat exchanger.
  • On an inflow side of the heat exchanger is Therefore, there is a removable grate on which the lint should settle and which can be easily removed to remove the lint.
  • the grid can be cleaned after its removal by rinsing with water from the lint.
  • Fluffs settle particularly at the lowest part of the channel, where a deflection of the process air from a vertically falling direction must take place in a direction horizontal to the heat exchanger, down.
  • DE 10 2005 035 652 A1 therefore discloses a tumble dryer which comprises a heat exchanger through which a process air flow can flow in a horizontal direction and a first duct, in which a lint filter is arranged, which is arranged in front of the heat exchanger and can be flowed through in a vertically falling direction by the process air flow , wherein between the channel and the heat exchanger a detachably attached to the heat exchanger and arranged in the horizontal direction and against the vertical direction falling open shell is arranged.
  • the invention is therefore based on the object to provide a clothes dryer with improved lint removal.
  • the object of the invention is also to provide a tumble dryer, which makes it possible to collect as possible all occurring between the drying chamber and the heat exchanger lint and dispose of those fluff, which is at the lowest part of the channel for the process air, where a deflection of the process air from a more or less vertically falling in a horizontal direction, knock down.
  • the invention thus relates to a tumble dryer with a drying chamber for the objects to be dried, a process air duct in which there is a heater for heating the process air and the heated process air can be guided by means of a blower over the objects to be dried, and at least a first lint filter , wherein a removable filter cassette is present, which has at least one of the process air flow through wall, which is at least partially provided with a second lint filter.
  • the invention enables improved removal of fluff, in particular of very fine fluff.
  • lint can be almost completely absorbed, which are carried in a dryer by the process air flow from the drying chamber.
  • An inventively equipped clothes dryer enables a functionally reliable and energy-saving operation, in particular by an improved heat exchange in a heat exchanger.
  • the two lint filters are placed in each case favorably and thus to achieve a significant improvement of their filter effect.
  • the filter cassette is attached to the heat exchanger removably in the process air channel between the drying chamber and a heat exchanger of the clothes dryer.
  • the second lint filter inserted in the filter cassette may comprise any material as long as it is suitable for retaining lint.
  • a material is used with small openings, which allows the collection of very fine lint.
  • the lint filter comprises fine filter gauze.
  • the second lint filter is fixedly connected to the filter cartridge.
  • the second lint filter is present in an insert which is detachably connected as at least one wall to a body part of the filter cassette. Preferably, the insert can be snapped into the body part.
  • the filter cartridge of the clothes dryer according to the invention preferably at least two lint filter are present, which are arranged at right angles to each other.

  • the inserts in which the first lint filter is located, to improve the fixation of the first lint filter and / or to improve the deposition of lint, at least one web, wherein the web or webs can be arranged horizontally and / or vertically again.
  • the first lint filter arranged between the filter cassette and the drying chamber lets through larger lint than the second lint filter.
  • the filter cartridge preferably has a handle to ensure easy handling.
  • the heat exchanger and filter cassette are preferably fastened together, in particular by means of a closure device, which lies outside the filter cassette. That way is the process air flow is removed from influencing by this closure device.
  • a diaphragm is preferably arranged on a flange surface of the heat exchanger facing the drying chamber.
  • This panel may be mounted as a separate part or integrated into the air-to-air heat exchanger.
  • the aperture is integrated in the air-to-air heat exchanger.
  • this panel is preferably integrated in a filter cassette designed as a shell.
  • this shell is particularly advantageous in the case of a tumble dryer which has a heat exchanger through which a process air flow can flow in a horizontal direction and a process air duct arranged in front of the heat exchanger and through which the process air flow can flow in a vertically falling direction, in which a second lint filter is arranged.
  • this dryer is then advantageously a removably attached to the heat exchanger and in the horizontal direction and against the vertical direction falling open shell available.
  • the heat exchanger in particular air-to-air heat exchanger, is removable. This is particularly advantageous because a removable heat exchanger can be cleaned more easily from lint.
  • the dryer according to the invention has a heat pump circuit with an evaporator, a compressor and a condenser.
  • an air-to-air cooler is arranged between the drying chamber and the heat pump circuit.
