[0037] In the drawings, in each case in a schematic view:

[0038] FIG. 1 shows a draining device comprising an integrated flushing device which is inserted into a container which is open at the top, here a bucket, a wet cleaning apparatus being arranged in the draining basket,

[0039] FIG. 2 shows the flow valve from FIG. 1 in the open position,

[0040] FIG. 3 shows the flow valve from FIG. 4 in the closed position, and

[0041] FIG. 4 shows the draining device from FIG. 1 without the wet cleaning apparatus and in the rest position.

IMPLEMENTATION OF THE INVENTION

[0042] FIG. 1 shows an embodiment of the draining device according to the invention for a wet cleaning apparatus. In the embodiment shown, the wet cleaning apparatus is formed by a mop, the mop head of which is arranged in the draining basket. The flushing device 1, which forms an integral component of the draining device, is provided for cleaning the wet cleaning apparatus and/or to wet the wet cleaning apparatus. The flushing device 1 comprises a fresh water reservoir 4 filled with fresh water, which reservoir is annular and surrounds the outer periphery of the draining basket 2 in the manner of an annulus. On its upper face 6, the fresh water reservoir 4 has a filling opening 8 for fresh water 3 and optionally cleaning additives, and on its lower face 7, a connection 9 for the fresh water line 5.

[0043] The fresh water line 5 connects the fresh water reservoir 4 to the draining basket 2.

[0044] The fresh water dome 10, which is axially pre-bulged in the draining basket 2, is arranged on the bottom of draining basket 2. The fresh water dome 10 is fluidically connected to the fresh water reservoir 4 by the fresh water line 5. The base 11 of the fresh water dome 10 is fluid-tight and the casing 12 has apertures 13 through which, as indicated schematically here, fresh water 3 can flow outwards in the radial direction.

[0045] The draining device is hooked, by a securing means 23 designed as a retaining collar, to the edge of the container 24 which is open at the top and is designed as a bucket. As a result, the preassembled unit is formed which comprises the draining device itself and the container 24.

[0046] In FIG. 1 the draining device is shown during cleaning of the cleaning apparatus and during spinning of the wet cleaning apparatus.

[0047] The flow valve 16, which is arranged in the flow direction 17 between the fresh water reservoir 4 and the fresh water dome 10, is in the open position. The flow valve 16 is transferred into open position by pressure being applied to the draining basket in the axial direction, also by the dead weight of the wet cleaning apparatus, such that the spring-loaded flow valve 16 is kept in the open position. As a result, liquid can flow through the fresh water line 5.

[0048] Provided that the draining basket 2 is in the position shown here and thus keeps the flow valve 16 in the open position, fresh water 3 flows out of the fresh water reservoir 4 through the fresh water line 5, and through the flow valve 16 into the fresh water dome 10 where, due to the rotation of the draining basket 2 and the fresh water dome 10 which is associated with the draining basket 2 so as to be stationary relative thereto, said water is spun outwards radially through the apertures 13 in the casing 12 of the fresh water dome 10, and thus cleans the mop head of the wet cleaning apparatus. After the mop head has been cleaned by the sieve-shaped draining basket 2, the fresh water used to clean the wet cleaning apparatus passes radially outwards into the container 24 and collects there together with the used washing water which is already in the container 24.

[0049] In the embodiment shown here, the rotation of the draining basket 2 does not depend on whether or not the fresh water dome 10 is supplied with fresh water 3.

[0050] Generally, it is also possible to push the draining basket 2 that is not in rotation 20 axially downwards, as shown here. The wet cleaning apparatus can be wetted, for example if it has not been used for a long time, is completely dry and is intended to be prepared for use as intended by wetting, without the draining basket 2 rotating.

[0051] The outflow opening 14 which opens into the fresh water dome 10 has a first height 15.1 which is less than the second height 15.2 of the connection 9 of the fresh water reservoir 4. The fresh water dome 10 and the fresh water reservoir 4 are interconnected in the manner of communicating tubes provided that, as shown here, the flow valve 16 is in the open position.

[0052] The drive 19 by means of which the draining basket 2 can be rotated 20 is mechanical in the example shown here. The drive 19 is formed by a pedal 21 which can be actuated by foot and comprises a connected gearing mechanism 22, the gearing mechanism 22 translating the up and down movement of the pedal 21 into a rotational movement to drive the draining basket 2.

[0053] FIG. 2 is an enlarged view of the flow valve 16 from FIG. 1. It is shown schematically that the flow valve 16 is moved axially downwards into the open position by the movement of the draining basket 2. The fresh water line 5 fluidically connects the fresh water reservoir 4 to the fresh water dome 10.

[0054] In FIG. 3, the flow valve from FIG. 2 is shown in the closed position. The draining basket 2 is unloaded here, as shown for example in FIG. 4, the unloading taking place by removing the wet cleaning apparatus from the draining basket 2.

[0055] Due to the unloading of the draining basket 2, said basket moves in spring-loaded manner into the starting position shown in FIG. 4, and the flow valve 16 closes the fresh water line 5. This means that there is no longer a fluidic connection between the fresh water reservoir 4 and the fresh water dome 10.

[0056] In FIG. 4, the draining device is shown in a state in which it is not loaded by the wet cleaning apparatus. It should be noted that the draining basket 2 is moved axially upwards, relative to the position of the draining basket 2 in FIG. 1, the flow valve 16 being brought into the closed position by this axial upward movement of the draining basket 2.
