Description

449 878 2 overflow, the emptying opening 15, which is arranged in the front part of the condensate collection container 11, has an aeration valve 17 in its lid 16.

The conduit 10 with its coupling half 14 is preferably stationary arranged in the machine housing and the coupling half 13 in or on the condensate collecting container 11. The condensate collecting container 11 is controlled by means not shown in such a way that the coupling halves 13, 14, when the container 11 is pushed into its purpose arranged opening on the front of the dryer, automatically pushed into each other. The plug-in pipe coupling 12 can be provided with a locking device (not shown), which locks when a corresponding pushing force is exerted on the container 11 and opens when an analogous traction force is exerted. Instead of the locking device on the plug-in pipe coupling, the collecting device 11 itself can be provided with a locking device which, in the case of an ice-cold container, locks automatically and can be opened by means of a push button on the front of the dryer.

The pump 9 is switched on either periodically by the program control or by the level monitor 8 and feeds the condensate from the collecting bowl 7 to the collecting container 11. The air in the collecting container 11 is forced out through the aeration valve 17 in the lid 16 of the inflowing condensate. If the maximum possible level in the collecting container 11 is reached, for example by not emptying, the aeration valve 17 closes and the pump f9 now works with a counter-pressure switch which switches on the pressure switch 18, which in turn switches off the pump 9 and switches the ongoing drying to cold operation. , at which no condensate is formed. At the same time, the corresponding signal device is activated, which is to draw attention to the full condensate collection container 11. However, it is also conceivable to simply let the pump 9 continue to operate under pressure. Since in this state it does not feed anything, the water level in the condensate collection vessel 7 increases, so that the level monitor 8 reacts and switches off the pump 9 and switches the drying to cold operation. The filled collecting container 11 is removed from its seat through the front of the device after the locking device has been opened, the valves in the two coupling halves 12, 14 closing. The two coupling halves preferably consist of hose couplings with water barriers. If, for example, the dryer were to be started by mistake without a collecting container 11 inserted, the pump 9 works against the closed valve in the coupling half 14, so that a slight overpressure is formed, which again causes the pressure switch 18 to switch over.

The coupling half 14 can also be made without a valve. In order to prevent the dryer in this case from being put into operation when the collecting container 11 has not been inserted, a position switch 20, which switches on

3 É '449 avs when removing the collection container, disconnect the circuit. The plug-in pipe coupling 12 shown in Fig. 2 consists of a coupling half 13, which is preferably arranged in the upper part of the condensate collecting container 11 and fastened therein by means of fasteners 26, while the coupling half 14 arranged at the end of the inlet stroke 10 is stationary in the machine housing by fastener 26. The coupling half 14 is provided with a right-angled inlet nozzle 21 and a closed drain nozzle 22, which can be opened when the condensate can be led directly into the sewer network through a sewer hose. Fig. 2 shows the plug-in pipe coupling 12 in coupled condition. The coupling half 13 consists essentially of a tubular injection-molded plastic part, in one half of which a spring-loaded piston 24 is arranged, which in the case of a split coupling closes to the outlet openings 25; In the other half, the coupling half 14, which also consists of an injection-molded plastic part with a smaller diameter, is sealingly inserted with its spring-loaded ring piston 25. The ring piston 25 is pushed out over the radial outlet openings 23 on its tubular guide part by split coupling. In the front part of the condensate collection container 11 there is the aeration opening 15, which is closed by means of a look 16. In order for the air in the container 11 to be able to escape when condensate flows in, an aeration valve 17 is integrated in the lid 16. The aeration valve 17 could also be arranged elsewhere in the roof of the condensate collection container. o F a t e n t k r a v: A washing dryer with a condensing device arranged in the drying air stream with a condensate collecting vessel (7), from which condensate formed during drying is fed by means of a pump (9) through a line (10) to a condensate collecting container (11) provided with a filling opening. characterized in that a plug-in pipe connection (12) is arranged between the condensate collection container (11) and the line (10); and that at least the coupling half (15) which is closest to the container and which comprises the filling opening is designed as a self-closing valve (24) when the coupling is disengaged; and that an aeration valve (17) is arranged in the upper part of the condensate collection container (11).
