• the device shown in Fig. 6 in a corresponding schematic view as used for Fig. 1, according to the second embodiment is considered. Since the device shown in Fig. 6 largely corresponds to the device shown in Fig. 1, only those features will be discussed in more detail with which this device differs from the device shown in Fig. 1.
• the device according to the second embodiment shown in FIG. 6 differs from the device shown in FIG. 1 essentially in that it omits the storage container SP1 provided in the device according to FIG. 1, the function of which is taken over by the rinsing container SB2 , If the rinse tank SB2 is filled with condensate water, then further condensate water supplied to it, as in the case of the apparatus shown in FIG. 1, arrives safely in the return duct RK through an overflow arrangement UB and thus directly back into the condensate water trough KW.
• Condensate water collected in the rinse tank SB2 can, like the rinse tank provided in the apparatus according to FIG. 1, be delivered to the downpipe FR for the purpose of cleaning the evaporator EV by abrupt opening of the closure part VT1.
• the rinse tank SB2 can be a manually removable rinse tank SB2, by which the condensate water pumped up from the condensate water tank KW can be disposed of.
• the disposal of the condensate water from the rinse tank SB2 can be carried out in that the relevant rinse tank SB2 is completely removed from the washer or dryer and emptied into a waste water discharge device. This emptying can be done manually. But it is also possible that the condensate contained in the purge SB2 pumped by means of an electrically operated pump and is discharged into the mentioned wastewater discharge device.
• FIGS. 7 and 8 show the rinsing container SB2 in a sectional representation as a cuboid receiving body, which is covered on its upper side by a cover DE.
• This cover DE can with the relevant receiving body, for example, be connected by a snap connection arrangement.
• the receptacle body of the washing container SB2 in question has a handle GR, with which the washing container SB2 enters a corresponding receiving opening GO of an appliance body GK of the washing machine, which also serves as a guide device for the washing container SB2. or tumble dryer is inserted.
• Fig. 7 shows the rinse tank SB2 in a state in which it is fully inserted into the receiving opening GO of the device body GK
• Fig. 8 shows the case that the rinse tank SB2 is slightly pulled out of this receiving opening GO of the device body GK.
• the sealing head DK of the closure part VT1 shown in FIGS. 7 and 8 is supported by the lever arm D1, which is received in the side walls of the flushing container SB2 the closure part VT1 so that the washing container SB2 with the closure part VT1 (to which the two lever arms H1 and H2 but not the lifting magnet HM belongs) relative to the mentioned receiving opening GO can be moved.
• Fig. 9 shows a guide unit GO forming part of the device body GK.
• the rinse tank SB2 is used in the guide unit GO.
• the washing container SB2 can be pulled out of the guide unit GO by means of the handle GR.
• the lifting magnet HM is arranged on an outer side of the guide unit GO forming part of the device body GK, wherein the plunger SO sealed for contacting with the underside of the outer lever H2 of the closure part VT1 by a, unspecified here, implementation in a lower shell US of the guide unit GO is guided.
• FIG. 10 shows the device from FIG. 9 in the same view, with the rinse container SB2 now partially being pulled out of the guide unit GO.
• the closure part VT1 is entrained and thus separated by solenoid HM and plunger SO.
• the return spring (not shown here) it is ensured that the outlet opening closes independently of the position of the washing container SB2.
• the rinse tank SB2 may be removed from the dryer and handled by a user, e.g. B. for dumping of condensate without there is a risk of unintentional opening of the outlet opening AU.
• the rinse tank can be divided into two chambers, namely a rinsing chamber and a collection chamber, which is subdivided by a separating or intermediate wall.
• the pumped up by the pump from the condensate water tank condensate then passes, for example, through the connecting channel first in the washing chamber. Since the partition is slightly lower in height than the height of the edge regions of a combination or short Kombibe- container performing rinse tank, the rinsing chamber is first filled with condensate water from the condensate water tank. If the rinsing chamber is filled with condensate water, further condensate water supplied to it passes through an overflow into the collecting chamber. If the collection chamber filled, water is derived from it via the overflow UB.
