Definitions

  • the invention relates to a clothes dryer with a dry air blower, one in a lint filter arranged in a dry air duct, a device for blowing off of lint from the lint filter and a device for removing blown off Lint.
  • German utility model DE 94 04 929 U1 is such a tumble dryer known, in which the lint filters blow nozzles to blow off the lint are assigned, which are connected to a compressed air source and with the help of Valves can be pressurized with compressed air.
  • this is disadvantageous at least one compressed air source and compressed air valves necessary, which are considerable Represent effort.
  • the present invention has for its object a dryer to create the type mentioned, in which the blowing and removing the fluff can be carried out by the lint filter with particularly little effort.
  • a tumble dryer the facilities to reduce or close the cross section of the dry air duct and for generating an air jet for blowing off fluff when the is on Has dry air blower.
  • the dry air flow is blocked and can be used to create an air jet for blowing.
  • the dry air duct can be narrowed or closed with a flap be, with a further device is provided with the under pressure standing air in front of the constriction or occlusion point and against the Lint filter can be passed.
  • This can be the flap or the device in general a device for closing or narrowing the dry air duct itself such as having a controllable valve with an air nozzle, with which the air jet generates and can be directed onto the lint filter.
  • Farther can also be provided an additional air duct, the constriction or Locking point is connected to the dry air duct. If the establishment has a controllable valve for generating the air jet, this can Delayed opening after closing or narrowing the dry air duct so that there is a higher pressure in front of the closure or constriction point can build up. Furthermore, it can also be controlled intermittently in order to intermittent blowing on the fluff filter to achieve a higher cleaning effect.
  • the additional facility required to reduce or close the Dry air duct cross section can be realized very easily and inexpensively.
  • These can be, for example, bodies that are pushed into the dry air duct or swung in, also being unfoldable or inflatable Hollow bodies are conceivable. It can also be provided that the Limits of the dry air duct are movable, and so the cross section of the Dry air duct can be reduced.
  • the device for reducing or closing the Cross section of the dry air duct can also be generated.
  • the air jet can with narrowed dry air duct in the remaining constriction or at closed dry air duct in a breakthrough in the device for closing of the dry air duct are generated.
  • the cross section of the dry air duct can be reduced in such a way that one is possible sharp and focused air jet can be directed onto the lint filter.
  • the air jet can be directed onto the edge of the fluff filter to create a peel off the lint covering from the edge.
  • a clothes dryer according to the invention advantageously has an air guiding device with which the dry air duct cross-section is reduced or closed a generated air jet with a flat impact angle on the fluff filter can be directed.
  • the air jet can have a flat impact angle to the edge of the fluff filter.
  • the flat blowing on the lint filter can be achieved, for example, by creates a cross-sectional narrowing of the dry air duct at the edge of the lint filter is and an air deflection part is arranged next to the lint filter directs the generated air jet at a flat angle to the lint filter.
  • Farther can reduce the cross-section of the dry air duct next to the lint filter be so that the air to flow through the lint filter this necessarily flows at an angle. If the dry air duct with a retractable or collapsible body is narrowed, this can be the narrowest part forming edge or the part located behind it in the direction of flow that the flow along the surface into the desired Direction is headed.
  • the fluff filter can be used shortly after the Dry air duct arranged and the narrowing of the dry air duct on the inside the dry air duct bend are generated so that the air jet passes the lint filter Flows at a flat angle or parallel to the surface, provided the lint filter aligned behind the bend essentially perpendicular to the dry air duct is.
  • a device is advantageously provided with which the blown and removed Lint can be transported to a collection container. In this way the fluff rarely needs to be removed by an operator.
  • the Lint can, for example, be suctioned off and placed in a filter Collection containers are directed.
  • a filter bag can be used which can be disposed of together with the fluff. Furthermore, can also during an opening in the wall of the dry air duct is released during the blow-off process through which the air jet can remove the blown-off fluff.
  • the collecting container can have a signal device for monitoring the filling level be assigned. For example, an operator can determine the degree of filling of the Show collection container or be designed so that they only when reached of a certain degree of filling gives a signal so that the operator the degree of filling does not have to constantly monitor the fluff collecting container.
  • a pivotable flap is provided, those that reduce or close the cross section of the dry air duct Position opens an opening in the wall of the dry air duct, through which the blown off fluff can be removed. That way with a very simple and inexpensive component of the dry air duct in the Cross section can be reduced or closed and at the same time ensured that the blown-off lint is removed by being blown off by the blow-off air jet through the open opening in the wall of the dry air duct to be blown through. A lint collection container can be connected to this opening his.
  • a simple flap can be used, which at one end is hinged to a wall of the dry air duct, in this case describes the free end when swinging into the dry air duct an arc and can create a constriction on the other side of the dry air duct, in which increases the flow rate when the dry air blower is switched on is so that the fluff can be blown away with the air jet generated.
  • the filter can be installed at an angle, so that the front edge is close the constriction and the rear part of the filter is not the movement of the flap with special needs.
  • the required angle of attack of the filter can be reduced by the lint filter is curved so that it is the trajectory of the free end essentially follows the flap. In this way, one edge of the lint filter immediately after the narrow point with the flap swung in and in addition the air jet generated in the constriction becomes flat Angle directed to the lint filter.
  • the flap in front on the outside of the Bend is articulated so that when swung into the dry air duct on creates the constriction in the inside of the end of the fluff filter.
  • blower output of the dry air blower for blowing off fluff for a short time can be increased. Since this process only takes a short time, one can also The nominal load capacity of the blower motor may be exceeded.
  • the tumble dryer 1 shown in Fig. 1 has a rotatably mounted drum 2 for receiving the laundry 5 to be dried.
  • the drum 2 has one perforated drum base and a loading opening on the opposite end, the articulated by means of a to the housing of the dryer 1 Door 9 can be closed.
  • a blower 3 can be used Dry air flow are generated by the drum 2, the door 9 and a cooled Condenser 6 for removing moisture from the dry air flow runs and is shown in Fig. 1 with arrows.
  • Heating device 4 is provided for heating the dry air flow.
  • a fluff filter 7 is in the flow direction behind the drum 2 Dry air duct arranged, with the detached fluff 11 in particular be held back.
  • a controllable flap 8 on Edge of the dry air duct hinged In front of the lint filter 7 is a controllable flap 8 on Edge of the dry air duct hinged. The flap 8 can be pivoted in this way be that there is only a small gap at the linkage leaves opposite wall of the dry air duct free.
  • the lint filter 7 and the flap 8 are designed so that the fluff filter 7 the movement of the flap 8th not hindered and that the flap 8 in its constricting the dry air channel Position can produce the gap as close as possible to the lint filter 7.
  • a control device 10 is provided for the laundry dryer and its components, which is arranged at the top of the front of the clothes dryer 1.
  • FIG. 2 shows the device for removing lint in a first operating position shown during the normal drying operation of the clothes dryer 1.
  • the flap 8 bears against the wall of the dry air duct, closes the opening leading to the lint collecting container 9 and gives the lint filter 7 completely free for the dry air flow. In this phase gather the lint 11 on the lint filter 7.
  • the control device 10 starts a cleaning phase initiated, in which the flap 8 is pivoted so that it to the Lint collection container 9 opens opening and the dry air duct up blocked a gap that is formed near an edge of the lint filter 7.
  • This state is shown in Fig. 3.
  • the fan 3 remains on during this time or can even be activated for a short time beyond its nominal power become. This creates a sharp jet of air in the gap created by the flap 8 generated, which blows the lint 11 away from the lint filter 7 and into the lint collecting container 9 promoted.
  • This has an air-permeable wall section that as far as possible from the supply opening in the dry air duct and the blown into it Can hold back lint 11.
  • the lint collection container 9 essentially airtight in its inclusion in the tumble dryer 1, with an air-permeable lint filter on its front is arranged.
  • the cleaning phase can, for example, during a cooling phase at the end of the drying program, if the heating is switched off 4 the blower for cooling the laundry 5 is switched on for a while remains.
  • FIGS. 4 and 5 are two further embodiments for the design of the Dry air channel shown to the air jet generated by the flap 8 on the To lead lint filter 7.
  • an air deflection part 12 on the wall of the Dry air duct can be arranged, the air jet flat on the lint filter 7 directs.
  • the dry air duct can be widened in front of the constriction to guide the air jet flat against the lint filter 7 from the outside.
  • Fig. 6 is an embodiment with a flat and perpendicular to the dry air duct arranged lint filter 7 shown, in which the lint filter 7 directly is arranged behind a right-angled deflection of the dry air flow.
  • the flap 8 is articulated on the outside of the deflection and can be pivoted inwards become.
  • the gap is also at an edge of the lint filter 7 generated, the air jet flowing against the lint filter 7 substantially in parallel.
  • the lint 11 is at the front end in the lint collecting container 9 passed, in which the air-permeable wall section here advantageously is arranged at the rear end so that the lint collecting container 9 from can be filled with fluff 11 at the back.
  • the inclusion of the dryer 1 for the lint collecting container 9 must be designed so that the Air escaping from the rear into the inside of the device and from there to the outside can.
  • FIG. 7 Another example of an inventive device for blowing off the Fluff 11 is shown in Figure 7, in which the flap 8 the dry air duct can completely block and at the same time a first opening through which the jammed Dry air can escape, and a second opening through which the Blown off fluff 11 can be removed.
  • This is done by the first Dammed dry air escaping through the opening by means of an additional air duct and a nozzle blown against the lint filter 7 from behind.
  • the one through the lint filter air jet blown through lifts the lint 11 and conveys it through the second released opening as in the previously described cases the lint collecting container 9.
