Definitions

  • the invention relates to a clothes dryer according to the preamble of patent claim 1.
  • Such tumble dryers have an internal closed air circuit through which heated air is passed through the damp laundry by means of a blower and then fed to a condenser.
  • the warm, steam-laden air flows through a first cavity which is penetrated, for example, by a tube block through which a cooling medium, for example tap water or cold ambient air, flows.
  • a cooling medium for example tap water or cold ambient air
  • the condenser is on an outer wall, e.g. arranged in the door.
  • the two cavities can be separated from one another by flat or corrugated walls or they are designed in the manner of a tube capacitor by installing a tube block in the door.
  • the door then forms one cavity and the interior of the tubes forms the other cavity (WO 90/08851 A1).
  • this type of condenser allows easy handling e.g. not for cleaning (fluff removal). Thermal expansions can also adversely affect the door construction and the connecting devices to the connecting parts if, for example in the case of a plastic construction with outer skin cooling, warm air is directly applied to the door surface.
  • the invention has for its object to provide a clothes dryer, the condenser is structurally simple and therefore easy to manufacture in series and inexpensive. Furthermore, the condenser should be versatile in use for different types of dryer and at different locations, and should be easy to handle for the user.
  • the capacitor then forms a separate compact unit, which in turn is made up of modular units that can be used in a variety of ways and that consist exclusively of assembled, for example glued or inserted Plastic parts exist and can be used as a whole in various places in the tumble dryer, for example in the door.
  • the assembly is particularly easy and can be done by machines if necessary.
  • the capacitor is a robust, reliable component that can also be easily removed, cleaned or replaced if necessary.
  • the condenser consists of only three differently shaped plastic parts, some of which are multiply present, namely the housing shell, the identically designed head and foot piece and the likewise identically designed tubes or corrugated walls.
  • the compact structural unit is formed from the connecting pieces and a tube block, while the housing jacket surrounding the block is formed from wall parts of the clothes dryer.
  • the modular units are connected to one another in such a way that the capacitor can be easily pulled out of the device housing or plugged in again. If, for example, a plug connection is selected in this embodiment, additional devices for securing and stabilizing the connection between the tubes and the connecting pieces are provided.
  • the modular design enables efficient production and versatile use of the capacitor.
  • different capacitors can be used in terms of structure and dimensions if certain requirements with regard to laundry drying are to be met.
  • the size ratios, the lengths of the tubes, the diameter ratios, the shape of the tube cross-sections, the number of tubes and the size of the flow spaces for the cooling air and / or the steam-laden circulation air could be changed, as well as the air routing and the air distribution, in order for the desired drying process to achieve optimal results.
  • these capacitors can be used at different points in the device housing, whereby they always have the same modular units.
  • the condenser can be accommodated in the door without tension even in the event of greater thermal expansion.
  • the capacitor is slidably inserted or locked into the side guide devices of the door. It is therefore easily removable for service purposes or for cleaning. Since the condenser can expand under the influence of heat and, according to its loose guidance, it is always tight and free of tension and since the seals are also integrated in the casing of the condenser, there is always a suitable adjustment to the housing openings of the tumble dryer. Tolerances and distortions of device housing parts, e.g. the door, therefore have no influence on the tightness of the condenser itself and the sealability to the device.
  • Fig. 1 shows schematically the flow of air in the door 1 of a clothes dryer.
  • the warm, steam-laden air enters the door body in the upper region in the direction of the arrow and is deflected downward, with it coming into extensive contact with the outside of the tubes 2 in the condenser 3.
  • the reference number 4 designates the flow of the cooled air leaving the condenser, which is then passed back into the washing drum 6 via heating elements.
  • cooler outside air enters the door body from below and flows inside the tubes 2 upwards, where it leaves the door through outlet openings (not shown).
  • the movement of the two air streams takes place via fans, not shown, in the counterflow principle.
  • a direct current principle or a cross current principle is also possible here.
  • the condensate formed during the cooling of the steam is collected and discharged in a manner known per se.
  • the openings of the door or of the condenser, through which the various air streams are passed when the door is closed, are provided with seals 7, 8 which, when the door is closed, rest against the corresponding openings in the tumble dryer housing.
  • the condenser 3 has on its surface facing the inside of the tumble dryer an opening 10 for the entry of the warm, steam-laden air and an opening 11 for the exit of the cooled, dehumidified air.
  • the opening 10 is covered by a lint filter 12, in front of which there is again a laundry deflector 13. These parts are assembled by detachable snap connections with the interposition of seals.
  • the capacitor 3 including lint filter 12 and laundry deflector 13 is gem.
  • Fig. 2b used in the door body. During installation, it is inserted from above into the lateral guide devices 9 or snapped into place from the front and held there in a sliding and floating manner.
  • the assembly thus completed has three openings that come into contact with the housing of the tumble dryer: the opening 10 for the inlet and the opening 11 for the outlet of the circulated air, and the opening 14 for the inlet of the outside air.
  • This air emerges from the upper ends of the tubes 2 and escapes to the outside through suitable openings near the top edge of the door.
  • the construction of the capacitor can be seen in FIG. 3.
  • the housing shell 15 consists of two spaced wide side walls 16, 17 and two narrow side walls 18, 19. As can be seen, the narrow side walls are angled in steps or can also be rounded.
  • the housing jacket thus has the shape of a flat sleeve and is formed in one piece from plastic.
  • a head piece 20 and a foot piece 21 are inserted into the open sides of the sleeve.
  • the connection is made by eyelets 22 formed on the free edges of the housing shell 15 and projections 23 formed on the sides of the head and foot piece, so that an easy-to-assemble snap connection is created.
  • the head piece 20 and the foot piece 21 are identical. They have insertion openings 24 in a symmetrical arrangement, into which the ends of the tubes 2 are inserted. 4, the insertion openings have a stepped diameter. In the part receiving the tube end, the diameter corresponds to the outer diameter of the tubes, so that they are held therein with an interference fit. In the subsequent part, the diameter of the insertion opening corresponds to the inner diameter of the tubes 2 and thus forms a stepless transition. In the part which extends further outwards, the insertion openings 24 are then flared, so that overall a particularly streamlined cross-sectional profile for the incoming cooling air is provided.
  • the modular compact structural unit 25, 25 ' is arranged below the drum 26, 26'.
  • the jacket is not part of the capacitor, but is formed by parts 27, 27 ', 28, 28' of the device housing, into which the capacitor is inserted in a slightly inclined manner.
  • the circulating air is redirected directly down from the drum 25, 25 'to the condenser (internal recirculation) and, after the water has been condensed out, is fed back to the drum via the heater 29'.
  • FIGS. 5a and 5b differ in that in FIG. 5a the moisture-laden warm air is passed through the tubes and the external cooling air is conducted around the tubes, while in the example according to FIG. 5b the moisture-laden warm air is directed around the tubes and the external cooling air is passed through the tubes.
  • the heat exchanger block 2 is floating in the side guides 9 so that it can expand in the direction of arrow 29 under heat, without stresses being introduced into the frame structure of the door.
  • the openings 10, 11 of the housing jacket 15 for supplying or discharging the warm, steam-laden air are enclosed by seals 30 and 7, respectively.
