Definitions

  • the invention relates to a laundry treatment machine, in particular tumble dryer with a rotatably mounted in a housing drum, a closable with a door feed opening, and a fan and a heater for generating a process air stream, which is intended to flow through the drum and a heat exchanger, wherein the heat exchanger is preceded by a filter insert accessible from the outside via an access door arranged in the front wall of the housing in a flow channel for the process air, wherein the filter insert consists of a depth filter block for filtering dust.
  • a lint filter device for a tumble dryer known.
  • the known clothes dryer is equipped with a filter device arranged in the process air stream, which is designed as a double screen.
  • This twin-wire is in this case preceded by the heat exchanger device, which consists of a lint filter, which is equipped with a coarse and a fine filter.
  • the heat exchanger device which consists of a lint filter, which is equipped with a coarse and a fine filter.
  • the two filters are arranged in a two-part hinged support frame, the entire unit is placed in front of the heat exchanger.
  • a laundry treatment machine of the type mentioned is from the DE 195 42 597 A1 known.
  • a drawer lint filter devices formed in the form of a drawer lint filter devices.
  • the drawers are located behind a mounting flap and, depending on the version, only contain a depth filter or a depth filter with flat filters connected in front of it, a so-called screen mesh.
  • These units exist made of several components and different materials.
  • the depth filters can only be removed from this drawer after unfolding or removing several components.
  • the removal and replacement of the depth filter is sometimes very expensive.
  • the operating times are relatively short, the depth filter must be cleaned depending on the device either after a few drying runs or after each drying cycle. Since most depth filters are accommodated by a drawer with a frame, a separate sealing of the drawer or the frame against the floor module or the front air duct is required.
  • the invention thus raises the problem of further developing a clothes dryer with a filter insert for the heat exchanger in such a way that the handling is substantially improved and simplified, the operating times of the filter insert being substantially extended.
  • a so-called depth filter, fine filter is positioned as a block without frame, directly in front of the heat exchanger.
  • the achievable with the present invention consist in the fact that a simple assembly and disassembly of the depth filter can be done behind the access door.
  • prolonged cleaning intervals are achieved through the use of such a depth filter block. Also, it requires no additional seals between the depth filter and the floor module or the front air duct.
  • the filter insert consists of a depth filter block for the filtration of fine dust or fine dust, which was not filtered by the sieves lying in front of it.
  • the depth filter block is self-sealing as a separate insert in the flow channel used.
  • the depth block has a box shape, wherein on its front side designed as a handle grip tab is arranged as a positioning aid.
  • the depth filter block can be easily and simply handled, so that it can be easily pressed into the cross section of the flow channel.
  • the box shape has an excess compared to the flow channel cross-section, which in particular ensures that formed as a box shape depth filter block is sealingly inserted in the flow channel cross-section, so that no portion of the process air can flow past the filter element.
  • the handle is formed on the depth filter block as a bow handle, which is fixed to the back of the depth filter block.
  • the depth filter block here consists of foam, wherein the foam used is formed for the insert on PUR-based with subsequently opened pores.
  • the depth filter block can be sucked off or easily and simply cleaned under running water.
  • the depth filter block designed as an insert part cooperates with a sensor for detecting the cleaning intervals.
  • FIGS. 1 . 2 and 3 each show in perspective a laundry treatment machine and here in particular a tumble dryer 1.
  • the clothes dryer 1 in this case comprises a housing 2 in which a rotatably mounted drum, not shown, is provided.
  • a door 3 In the front of the housing 2 is a door 3, which covers the feed opening.
  • the three figures each show the clothes dryer 1 in the closed situation.
  • In the housing 2 are further a fan and a heater for generating a process air flow. This flows via a heat exchanger 14, which is arranged in the region of the bottom of the housing 2.
  • a filter element 4 In front of the heat exchanger 14 is a filter element 4, as he, for example, in the Figures 2 and 3 can be seen, this filter element 4 is arranged in front of the heat exchanger 14, based on the direction of the process air flow.
  • This filter element 4 is held from the outside via a arranged in the front wall 5 of the housing 2 inspection flap 6 in the flow channel, the only hinted here can be seen.
  • the flow channel is formed here by the cross section, as he, for example, from the open situation according to Fig. 2 or 3 can be seen.
  • the depth filter block 7 is in this case used as a separate insert itself sealing in the flow channel 8.
  • the depth filter block 7 is designed such that it fills the entire flow channel cross section and is pressed into this, as it is the situation of FIG. 3 shows where the depth filter block 7 is used disappeared in the machine housing 2. Is the depth filter block 7, as he is in the situation of FIG. 2 is used, is still used according to the inspection flap 6 with heat exchanger cover 9 in the opening cross-section of the front wall 5, so that the closed image results, as shown in the FIG. 1 is shown.
  • the depth filter block 7 in this case has a box shape, as they better and more clearly from the FIG. 4 it can be seen where, in isolated representation, the depth filter block 7 is shown from the front and the back. Like from the FIG. 4 can be seen, is arranged on its front side 10 designed as a handle 11 grip tab as a so-called positioning aid.
  • the box shape in this case has an excess compared to the flow channel cross section, so that a slight squeezing into the flow channel is required when inserting the depth filter block 7 in order to achieve in this way a sealing insert of the depth filter block 7 in the flow channel 8.
  • the handle 11 is formed on the depth filter block 7 as a bow handle 12 which is fixed to the back 13 of the depth filter block 7.
  • formed as a depth filter block 7 item consists of foam.
  • the foam used for the insert is formed on a PUR basis with subsequently opened pores.
  • a bubble density in the range between 20 to 50 bubbles per square inch (PPI) with a foam thickness of 20 to 50 mm has proved to be advantageous, so that a good filter effect and a good flow through the process air flow is achieved.
  • the foam used can be sucked off or washed out under running water.
  • the depth filter block 7 designed as an insert part can cooperate with a sensor for detecting the cleaning intervals.
  • the depth filter block 7 is positioned in the lower parts of the front air duct 8 in the area in front of the heat exchanger 14 behind the heat exchanger cover 9 and the inspection flap 6.
  • the filter element 4 is added without additional frame or drawer in the front air duct or in the floor module.
  • the filter element 4 assumes not only the filter but also a sealing function. This eliminates the need for a separate seal.
  • To remove the filter element 4 only the access door 6 and the heat exchanger cover 9 need to be dismantled.
  • the filter element 4 is then freely accessible and can be removed from the device 2. Due to the open-pore structure, the filter element 4 only has to be removed and cleaned after several to a few hundred drying cycles. For this, only the depth filter block 7 must be pulled out and washed out under running water.
