Definitions

  • the EP 2 843 103 A1 Disclosure reveals a washer-dryer with a heat pump module for generating the drying air.
  • the heat pump module is located above the tub and includes a fan for generating a process airflow that flows through the drum to dry the laundry inside.
  • the heat pump module includes a filter element consisting of two screens arranged transversely to the flow direction and parallel to the cross-section of the duct section, respectively.
  • the invention is based on the objective of providing a compact laundry treatment machine with a lye tank and process air generator with an improved filter for cleaning the process air.
  • the process air generator is housed within a standard enclosure. This is achieved by placing the process air module in the space above and to the side of the washing tub.
  • the duct section is designed as a flat, wide box, preferably housing the heat exchangers in appropriately sized sections.
  • the air inlet is located in the lower rear end wall of the washing tub, and the air outlet is located in or on the washing tub in the upper front, central area of the front end wall.
  • the air outlet can also be incorporated into a bellows, which forms a tubular connecting channel from the loading opening in the front wall to the loading opening at the end of the drum or washing tub.
  • the bellows can be considered part of the washing tub with regard to the process air routing.
  • the flat box forming the duct section is located between the air inlet and air outlet and is oriented approximately horizontally, meaning the wide sides are horizontal and the narrow sides are approximately vertical. All position and direction specifications refer to the device's standard operating position.
  • the process air module or the supply pipe includes a filter element, which is provided in the duct section upstream of the box-shaped duct section or within the duct section itself.
  • the filter element is removable and located in the front part of said duct section.
  • the filter element serves to remove lint from the process air before it enters the duct section containing the heat exchangers, preferably located therein.
  • it is removable and positioned or arranged within the duct section or in the pipe section upstream of the duct section. The filter element can be removed and inserted or accessed through a housing opening in the duct section or pipe.
  • the filter element is designed as a flat body with a filter medium and is positioned obliquely beneath a
  • the filter element is arranged at an angle of 5° to 45°, preferably 7° to 30°, in the direction of flow of the channel section.
  • the filter element is slidably inserted into the pipe section, wherein the housing or an aperture on the housing includes an access opening to the channel section or pipe, and the channel section or pipe includes an access opening for the filter element that can be closed with a cover.
  • the channel section has guide elements that are inclined or sloped inwards to guide the filter element obliquely into the channel section. This allows the filter element, positioned obliquely in the channel, to be easily pulled out or inserted through a small access opening.
  • the control unit is configured and programmed to activate the process air generator or fan when a drying program starts.
  • the fan is then activated for a predetermined duration to ensure that the damp laundry is exposed to a stream of process air. This loosens lint from the fabric and transports it to the duct or duct section.
  • the filter element positioned upstream of this duct section separates the lint and particles present in the process air stream.
  • the filter element has a length extending in the direction of flow of 5 cm to 30 cm, preferably 10 cm to 20 cm, and a width of 5 cm to 35 cm, preferably 7 cm to 25 cm, and particularly preferably 10 cm to 20 cm.
  • the width is the measure of its extent perpendicular to the direction of flow.
  • the thickness of the filter element preferably has a value in the range of 0.1 cm to 2 cm, more preferably 0.5 cm to 1.5 cm.
  • the filter element can be multi-layered, comprising at least one support layer, a fine filter layer made of nonwoven fabric, open-pore foam, or a multi-layered fabric applied to the support layer, and a layer of gauze or sieve-like fabric applied to the fine filter layer.
  • the fine filter layer has a thickness in the range of 0.3 cm to 3 cm, more preferably 0.5 cm to 2 cm. This allows for very good separation of fine lint in a fine-open-pore design, with very good airflow and a flow loss in the range of 1% to 5%.
  • the guide means are each designed as a rail or web, which are each arranged at an angle with a value in the range of 2° to 25°, preferably 5° to 20°, more preferably 7° to 15°, on the respective inside of the opposite, lateral channel walls.
  • the channel section in which the filter element is housed is a flat hollow body with a height in the range of 2 cm to 8 cm and a
  • the filter element is designed with a width in the range of 5 cm to 35 cm, preferably 7 cm to 25 cm, and particularly preferably 10 cm to 20 cm, wherein the filter element is shaped as a flat, planar body and is arranged obliquely in the duct section.
  • the filter element is arranged at an angle within the duct section, either inclined or obliquely, and rests with one broad side against the underside and in the front region of the duct section, and with the opposite broad side against the top side in the rear region of the duct section.
  • front region and rear region refer to the direction of flow of the process air stream through the duct section, with the front region defining the inlet area to said duct section.
  • the filter element can be installed in the duct section such that one broad side rests against the top side and in the front region of the duct section, and the opposite broad side rests against the underside in the rear region of the duct section.
  • the filter element with its surrounding edge is sealed in the aforementioned channel section so that no lint can bypass the filter element due to adjacent process air flow.
  • the control device can be designed to keep the heat pump device or compressor switched off or to switch it off during the ventilation phase, so that only an airflow is generated without conditioning the process air.
  • control unit can be designed to switch on or activate the heat pump device or compressor during the ventilation phase, so that the The process air is conditioned.
  • the process air can be warmed or heated. This makes some textile fibers more supple, resulting in improved particle removal when the laundry items are moved.
  • the laundry treatment appliance as a washer-dryer, it comprises a detergent dispenser drawer with a handle plate, which is designed as part of the front panel when the detergent dispenser drawer is inserted, wherein the access opening for the filter element or the cover plate of the filter element is arranged to the side of the handle plate for the detergent dispenser drawer.
  • the air inlet is located below the height of the drum's axis of rotation. This places the air inlet in the lower section of the rear end wall, ensuring a good and straight airflow through the inlet to the drum and through the drum itself, especially if the drum's rear wall is perforated or partially constructed as a mesh. The air is not deflected within the tub.
  • the air outlet is located in the upper front section of the drum's end wall, ensuring that the process air flows diagonally upwards through the drum from back to front.
  • the laundry moving inside the drum does not reach the outlet and therefore cannot become blocked, as the laundry always moves downwards, away from the outlet, due to gravity. This ensures that the flow of process air is not obstructed.
  • the box-shaped duct section so that its central axis leads from the center of the air outlet into the fan. This minimizes the deflection of the process air within the duct section from the inlet to the outlet towards the blower, resulting in little to no flow resistance. Furthermore, the path of the process air is kept short, thus minimizing heat losses.
  • the blower is arranged between the rear and back walls of the housing because the installation space is particularly suitable for this.
  • the installation space is limited in the front area because the front loading opening occupies a large portion of the space between the front end wall and the front wall of the housing.
