In the in 3 selected representation is a side longitudinal section of a laundry care device 100 shown in the loaded state during the pump-over injection process. In 3 is the device top 111 , the back of the device 105 , the front of the device 103 and the bottom of the device 109 of the laundry care device 100 shown. At the front of the device 103 is a device loading opening 113 arranged, which through a device door 115 is closable, through which the interior of the laundry care device 100 is accessible for loading. In the interior of the laundry care device 100 is a tub 119 for holding the washing liquid and a laundry drum 117 for receiving laundry 139 arranged, the laundry drum 117 along a rotation axis 141 is rotatable. In this case, the axis of rotation extends 141 from the front of the device 103 to the back of the device 105 of the laundry care device 100 ,

Between the laundry drum 117 , the tub 119 and the appliance door 115 is a cuff 143 arranged. The cuff 143 provides a fluidic seal between the laundry drum 117 or the tub 119 and a device housing 145 of the laundry care device 100 for sure. Furthermore, the cuff decoupled 143 the suspension system mounted on spring dampers from the stationary device housing 145 , At the resting portion of the cuff 143 is an inlet nozzle 123 arranged, which is formed, from the inlet nozzle 123 pumped out washing liquid 147 along an injection axis 149 on a diverter 151 to guide, with the diverter 151 in particular, as a curved or curved metal plate, rubber plate, plastic plate or as a curved curved window glass portion is formed and / or as in 3 is shown on an inside 153 the appliance door 115 is formed.

The diverting device 151 is on the inside 153 the appliance door 115 arranged and formed on the diverter 151 impinging washing liquid 147 in the direction of the laundry drum 117 , in particular parallel to the axis of rotation 141 to redirect and the redirected washing liquid 147 along the axis of rotation 141 in the laundry tunnel 155 in the laundry drum 117 inject. This is the redirected washing liquid 147 especially from the front of the device 103 out in a laundry tunnel 155 the at the laundry drum 117 adjacent laundry 139 initiated.

The diverting device 151 has a curved diverting surface 157 on, against which the on the diverter 151 impinging washing liquid 147 is sprayable to the washing liquid 147 in the direction of the laundry drum 117 , in particular parallel to the axis of rotation 114 redirect. Here is the diversion area 157 in particular as a curved or curved diverting surface 157 educated. To effectively introduce the washing liquid 147 in the laundry tunnel 155 to enable closing the injection axis 149 with the rotation axis 141 the laundry drum 117 a diversion angle 159 from 75 ° to 105 °, in particular from 90 °, to an axis-parallel wash tunnel 155 To achieve injection. To effectively fanning the redirected washing liquid 147 can ensure the diverter 151 a profiled surface structure, in particular a depression, groove or rib, have. To effectively bundle the redirected washing liquid 147 can ensure the diverter 151 a bundling element, in particular a bundle nozzle or a bundle nozzle section, have.

At one of the laundry drum 117 facing side 161 the diverting device 151 is a leading edge 163 the diverting device 151 arranged. The diverting device 151 points at the edge of the projection 163 in particular a progressive slope course. The leading edge 163 Make sure the washing liquid 147 at a reduced pump pressure and a resulting reduced injection pressure of the injected washing liquid 147 not on the laundry drum 117 facing side 161 the diverting device 151 flows down without the laundry 139 in the laundry drum 117 to effectively wet. The leading edge 163 and in particular the progressive gradient of the diverter 151 at the edge of the projection 163 ensures that the stream of washing liquid flows over the edge of the projection when flowing 163 from the diverter 151 releases and effectively along the axis of rotation 141 the laundry drum 117 in the laundry drum 117 can be directed.

Thus, the on the inside 153 the appliance door 115 arranged diverter 151 directly to the introduction of the washing liquid 147 in the laundry 139 used. Through the surface contour of the diverter 151 a washing liquid jet deflection is made. So can the washing liquid 147 starting from the on the cuff 143 arranged inlet nozzle 123 first radially into the middle of the tub 119 injected and then at the diverter 151 be deflected by about 90 ° to the deflected washing liquid 147 in particular along the axis of rotation 141 the laundry drum 117 , in particular parallel to the axis of rotation 141 or congruent to inject. Thus, the injection jet deflection in a conventional diagonal injection from the cuff edge on straight, half-axial way in the wash tunnel 155 be completely avoided by the rotating laundry ring, because the door 115 continues to come in the radially outer regions of their task after the laundry 139 from the cuff 143 but can cause in the central area a Wachlaugenumlenkung the injection jet of the pumping system. The geometric design of the original injection corridor between the appliance door 115 , Cuff 143 , Tub 119 , Laundry drum 117 and rotating laundry ring thus has no influence on the function of wetting or flooding of the laundry.

The diverting device 151 the appliance door 113 can be used not only for injection liquid jet deflection, but also for the geometric design of the spray pattern. Thus, by designing the diverter 151 For example, a so-called fan beam or a punctually bundled beam can be realized. Thus, for example, the laundry net phase can be accelerated or on particularly gentle textiles To be received. The detachment of the washing liquid jet at the diverter 151 can through the edge of the projection 163 be implemented, in which the slope progresses progressively, so that the washing liquid 147 safely at the final leading edge 163 replaces.

The diverter according to the invention 151 allows a load-independent injection of washing liquid 147 , in which it is always ensured that the injection jet is obstructed or interrupted neither by the Waschgutgeometrie, in particular Wäschering, nor by the window geometry. So can functionally always the necessary washing liquid 147 for rewetting and flooding the laundry 139 along the axis of rotation 141 be added to the vibrating system.

Through the diverter 151 can at the injection jet deflection on the door 115 be influenced at the same time on a Waschflüssigkeitsstrahlgestaltung. So not only the place of occurrence, but also the surface of the injection in the washing ring can be influenced. In addition, this also affects the beam intensity as it were, because a fanned-out beam selectively represents, for example, a lower tissue load on the laundry due to the impinging washing-fluid jet.

Advantageously, the injection process for the user can be visualized by the beam deflection on the door geometry, if the appliance door is realized as usual by a sight glass. A drum interior lighting, which is provided on the same sleeve portion as the diverter 151 can clarify the activity of the injection process again, because the light cone and injection jet are inclined with the same orientation on the drum center, or aligned.

The appliance door 115 has an outside 165 on which one in 4 not shown outdoor area of the laundry care device 100 is facing. The appliance door 115 has an inside 153 on which one in 4 Laundry drum, not shown 117 of the laundry care device 100 is facing.

On the inside 153 of the appliance door 115 is an exemplary diverter 151 arranged, which is formed on the diverter 151 impinging washing liquid 147 parallel to the axis of rotation 141 in the direction of the laundry drum 117 of the laundry care device 100 redirect. In the in 4 embodiment shown is the diverter 151 to the inside 153 the appliance door 115 formed. The diverting device 151 has a diverting surface 157 on, against which the on the diverter 151 impinging washing liquid 147 is sprayable to the washing liquid 147 in the direction of the laundry drum 117 parallel to the axis of rotation 141 redirect, with the diverting surface 157 as a curved or curved diverting surface 157 is trained.

The diverting device 151 points to a laundry drum 117 facing side 161 the diverting device 151 a leading edge 163 which is formed, the redirected washing liquid 147 in the direction of the laundry drum 117 to lead.
