Definitions
- the invention is based on a household tumble dryer with a condenser arranged in the process air circuit, which contains a plurality of stacked heat exchanger plates with cavities which are in a cooling circuit which is as hermetically sealed as possible against the process air circuit, with the respectively assigned cavity enclosing, accessible from an operating side of the dryer from the front edges of the plates against the process air flow.
- the entire block of heat exchanger plates can be made removable from the housing inside the tumble dryer so that it can be handled more easily for cleaning. For this purpose, cleaning under running water is provided.
- cleaning under running water is provided.
- the adherence of the deposited lint is so great that the lint must be processed with additional tools (e.g. with a bottle brush) to remove it.
- this object is achieved in that a grating is provided from strips covering the end edges, which are connected to one another by narrow transverse ribs, which extend a short distance in the direction of the process air between the plates and are connected to one another at their ends by crosswise arranged stripping lips are that connect closely to the plate surfaces, but are otherwise aerodynamically shaped for the process air.
- the handle should be placed in front of the front surface of a strip so that it does not stand in the direct air flow in front of the space between two plates.
- the gratings, the transverse ribs and the wiper lips consist of a one-piece molded plastic part.
- the tumble dryer in FIG. 1 has a housing 10 with an internal drying space 11, which can be designed as a horizontally rotatably mounted drum. Between this and the rear wall of the dryer there is a supply air channel 12, in which the process air is heated by means of a heating device 13 and blown into the drying room by a fan 14 via a grid wall 15. At the front of the dryer there is a loading opening 16 for loading the laundry items to be dried. The loading opening is then closed by a door 17.
- the condenser is shown cut along the flow direction of the process air and contains heat-conducting plates 21 with cavities through which a cooling medium flows, for example fresh cooling air, transversely to the process air.
- the process air is indicated by a filled arrow on the warm side and by a dashed line on the cold side. longitudinal arrow shown.
- the moisture collects at the outlet of the condenser and flows off to the condensate collecting container 22, from which the condensate can be pumped out or removed manually.
- a door or flap 23 which can be opened by the operator for the purpose of cleaning the condenser 2.
- the wiping lips close to the surfaces of the plates 21, so that when the gratings are pulled off, the wiping lips scrape over the plate surfaces and lift off any fluff that may be attached. So that the wiper lips 26 do not excessively impede the process air flow, they are shaped in a streamlined profile.
- the transverse ribs 27 arranged above the uppermost plate 21 form the outer end of the gratings and, in the example of FIG. 2, only carry wiping lips directed towards the plate 21 below.
- the uppermost transverse rib 27 also has an upward wiping lip 26 in order to wipe off any fluff attached to the inner surface of the condenser housing 2.
- the transverse ribs 25 and 27 are also not shaped like a window as in FIG. 2, but are shaped as filled strips. Their front leading edges between the strips 24 covering the end edges are also shaped to be aerodynamic.
- a handle 28 is arranged on a strip 24 so that the tensile forces act uniformly on all parts of the gratings.
- the gratings are now removed from the plates for cleaning.
- the wiping lips 26 scrape the lint deposited in the inflow area from the plate surfaces. They either adhere to the front edges of the plates or to the wiping lips 26, from where they can be easily removed in each case.
- the gratings themselves will also be covered with adhering fluff that can be easily rinsed off under running water.
- Another advantage for the designer of a condenser equipped according to the invention is that he can firmly integrate the entire condenser block in the housing of the tumble dryer, thereby opening up the possibility of considerably reducing the housing parts for the condenser block and the process air and cooling air guides. to seal better. This will significantly increase the efficiency of such a tumble dryer.
- the gratings indicated schematically in FIG. 4 have springs 30, each with a common root 31, which holds the strips 24 together, as transverse ribs reaching between the plates 21 in the direction of the process air.
- the wiper lips 32 are connected to the ends of the springs 30 and are engaged in beads 29 in the operating position of the gratings.
- the gratings are fixed in their operating position and, on the other hand, sufficient force is exerted on the plate surfaces to scrape off the fluff.
- the wiper lips 32 immersed in the beads 29 are completely removed from the process air stream and therefore do not form any flow resistance.
