Description

The invention relates to a household appliance for the care of items of laundry, with a dispensing tray and a layer container, which is connected to the dispenser via an inlet strand, wherein in the feed line a vapor barrier device is formed in a curved line section.

From the DE 10 2006 029 953 A1 is a washing machine with a controllable fresh water inlet for at least two detergent chambers known. In a top portion of the housing of the washing machine Waschmitteleinspüleinrichtung is arranged. From an uneven bottom of the housing of this Waschmitteleinspüleinrichtung down detergent feed lines open to the inlet to a cuff on the one hand and to the inlet to a tub on the other.

Through this Waschmitteleinspüleinrichtung a ventilation of the tub without additional ventilation line is given, and due to the two separate detergent supply lines and their connection to the uneven bottom of the housing of the detergent supply device is guaranteed always one of these two lines unoccupied.

From the DE 10 2004 060 709 A1 is a Einspülanordnung with a water supply for a washing machine known. An induction bowl of Einspülanordnung is formed with an upper part and a lower part, wherein the lower part has an outlet nozzle and a trough as a water mask. In the water contained in the trough protrudes from above a partition, which divides the lower part in conjunction with the water contained in the trough and the water seal formed thereby in two separate rooms. The partition wall is integrally formed on the lower part or preferably with the upper part. As a result, the production of the components is very complex and difficult, especially if they are designed as injection-molded parts.

It is an object of the present invention to provide a Einspülanordnung and a household appliance for the care of laundry, in which or in which a compact construction of a liquid flushing on the one hand and a ventilation on the other hand is reached and the production is simplified.

This object is achieved by a Einspülanordnung and a household appliance according to the independent claims.

An inventive Einspülanordnung for a household appliance for the care of laundry comprises a Einspülschale having an upper part and a lower part connectable thereto, wherein in the lower part of a water supply device is formed with a water receiving trough, and an outlet nozzle is formed on the lower part, which opens into the water receiving trough , It is formed a separate partition to the lower part, which is attachable to the lower part, and in the arranged state of the partition, a siphon between the outlet nozzle and the water receiving trough is formed. By such a configuration, the one-piece production of the lower part is simplified and cheaper. Especially when manufactured as an injection molded part, the design and shape of a siphon is extremely difficult and error-prone. By virtually the partition is made and provided independently and as a separate component and only later arranged as a non-destructive detachable component and removable again, these problems are eliminated in the production, on the other hand, but also achieved the desired design of a siphon.

It is particularly advantageous if the dividing wall is attachable to the lower part in a latching manner. As a result, a very fast and secure position mounting is possible, in which case the partition can be easily removed again.

The lower part preferably has a partial channel opening onto the outlet connection of a ventilation channel integrated in the induction bowl. By such a design of the dispenser shell, a highly integrated system of a vapor barrier on the one hand and a corresponding ventilation on the other hand can be achieved. In the context of the invention, a vapor barrier is a substantially U-shaped pipe system, wherein the pipe strands of the pipe system communicating with one another can be filled with a liquid medium to a level such that no gaseous media flow is made possible. The vapor barrier is effective when the pipe system is filled to this level. The pipe system may also have a deviating from the U-shape, provided that the mutually communicating pipe strands of the pipe system can provide the same effect such a vapor barrier.

It is preferably provided that the sub-channel is bounded by a wall, which is also a boundary wall of a water receiving space of the dispenser tray. The compact design is favored. In particular, however, this achieves a particularly noteworthy variant with regard to the condensation of the gaseous medium conducted via the venting channel.

It is preferably provided that the sub-channel is formed substantially over the entire length of a water receiving space of the dispenser tray in the lower part.

In particular, it is provided that the sub-channel is closed by a second sub-channel in the upper part, when the lower part is connected to the upper part.

In particular, it is provided that the venting channel is guided from a front end of the lower part, on which the outlet nozzle is arranged, to a rear end of the lower part and up into the upper part and from there back to the front end to an outlet opening out. As a result, a particularly long path is achieved in the dispensing tray for the gas flow, which is guided along a particularly long path along the water receiving space, in particular. The desired condensation is thereby particularly favored.

Preferably, it is provided that a separate partition to the lower part is formed, which is attachable to the lower part, and in the arranged state of the partition, a siphon between the outlet nozzle and the water receiving trough is formed.

Preferably, it is provided that the upper part has a guide wall through which the interior of the dispenser shell is divided into two dispensing channels in the assembled state of the upper part with the lower part.

In particular, it is provided that a first flushing channel is formed with the water supply device as a vapor barrier.

Preferably, a second Einspülkanal with the water supply device is designed as a connection to a tub of the household appliance.

Furthermore, the invention also relates to a household appliance for the care of laundry items, in particular a washing machine or a washer-dryer, which has an inventive Einspülanordnung or an advantageous embodiment thereof

A preferred household appliance for the care of laundry comprises an induction bowl and a tub, which is connected to the dispenser shell via at least one inlet strand. In particular, liquid medium, in particular detergent and water, are fed to the sleeve or to the tub via the feed line. In the feed train, a vapor barrier device is formed in a curved line section. In the line section, a ventilation channel is formed, which opens at a first end of the line section. At the first end of this ventilation duct is separated from one of the vapor barrier device associated feed channel for supplying liquid medium from the dispenser tray to the tub. Thus, a line section is formed in which both the ventilation channel and the feed channel open at a first end and at this first end these two channels are also separated from each other. In this line section two different channels are thus integrated in extremely compact and space-minimizing design, which are also designed separated from each other. As a result, a line section is also generated with a connection at this first end, which has two channels. The connection of two separate lines is no longer required, but it is virtually only on this first end a connection performed. Thus, a line section is provided which has an integrated multi-path system, for which purpose a water inlet system and an air duct system are realized in one component. For this purpose, separate air and water ways are realized at the front end. As a result, a vapor barrier is formed in the water inlet, which prevents the steam or condensate outlet from a tub. In addition, a functional ventilation in the area of the cold water inflow of the induction bowl is achieved by the warm process air. This causes a temperature compensation and prevents water condensation. Effective prevention of vapor escape from the inflator formed by the tub and drum is achieved.

It is preferably provided that the first end of the line section is a level end viewed in terms of level. As a result, the conceptual realization of the vapor barrier on the one hand and the ventilation on the other hand can be achieved particularly secure and a particularly simple connection to the dispenser shell is guaranteed.

It is preferably provided that the ventilation channel is formed in regions circumferentially around the feed channel at the first end. By no complete circulation is formed, a particularly mechanically stable configuration is realized and a particularly suitable positioning of the ventilation duct and the feed channel is achieved. In particular, the venting can then be designed positionally quite specific to this first end and done specifically targeted and dense at the transition to an induction dish and a vent there.

Preferably, it is provided that the ventilation duct opens into the supply channel at a point of confluence, wherein the point of confluence, viewed in terms of level, lies above a liquid level in the feed channel in which the vapor barrier is formed. This junction is thus formed at the end remote from the first end of the line section of this ventilation channel and thus at an in the line section inwardly offset position.

Preferably, it is provided that the feed channel has a flexible channel section after the mouth of the ventilation channel, in particular this flexible channel section is designed as a corrugated pipe. By such a configuration, an otherwise, in particular rigidly formed line section or intake line experience a certain reversible deformability to experience no damage in a moving system during operation of the household appliance.

It is preferably provided that the inlet strand is formed as a one-piece component in the form of the line section itself, in particular formed as a molded part.

This filling hose or this line section accomplishes the connection from the filling arrangement with the dispensing tray and the detergent dosing to the tub. This line section also has the task to transport the process water in the tub. Due to the dynamic movements of the washing unit or of the oscillating system, the movement compensation of this line section takes place, in particular, by means of a flexible fold region or the already mentioned flexible channel section.

Due to the very specific configuration of the line section, this simultaneously transports the heated process air to a condensation area in the flushing arrangement. The special feature is that the air duct is integrated into the line section, but is transported via a separate channel from the waterway. A transport over the waterway back is excluded by the default Wasservorlageeinrichtung. The required passage cross section for the air duct is achieved in particular by an eccentric arrangement of a nozzle in the nozzle. As a result, in addition to a particularly space-minimized, and a simple connection principle gestaltendes, also allows a mechanically stable and robust concept.

The sealing of the inner and outer connecting pieces is advantageously achieved by specific sealing elements or sealing ribs. The hose connection can be additionally secured by suitable hose clamps on the outer nozzle.

An embodiment of the invention will be explained in more detail with reference to schematic drawings. Show it.

8th another illustration of the execution in 7 ,

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In 1 is as a water-conducting household appliance 1 , which is designed for the care of laundry, a washing machine shown. The household appliance 1 However, it can also be a washer-dryer.

The household appliance 1 has a tub 2 in which a drum 3 is arranged for receiving the laundry items and is rotatable about a vertical axis of rotation to the plane of the figure.

In addition, the household appliance includes 1 a first intake line 4a , over the fresh water in the drum 3 is feasible. Furthermore, there is a connection 5 trained, which is connectable to a domestic installation or the like. From the connection 5 leads a fresh water pipe 6 in the interior of the household appliance 1 , In the fresh water pipe 6 is a check valve 7 arranged, which is driven, for example, by a controller according to a program flow. The Fresh water pipe 6 leads over a free air gap in a Einspülschale 8a a flushing arrangement 8th , In the dispenser bowl 8a For example, a laundry treatment agent, in particular a detergent, can be provided, which is connected to the fresh water through a pipe 9a of the intake line 4a is rinsed.

The household appliance 1 has a flexible cuff 10 on top of that with the tub 2 connected is.

As from the illustration in 1 can be seen, opens the first intake line 4a via a first feed point 11a to the tub 2 , A pipe section of the intake line 4a flows at this feed point 11a to the tub 2 , Thus, over the intake line 4a Fresh water and optionally a mixture of fresh water and a laundry treatment agent in the drum 3 be guided.

The household appliance 1 also has a pumping string 12 on top of a flap 13 , a drain pump 14 and a line 15 includes. With the flap open 13 can in the tub 2 provided liquor by operating the drain pump 14 over the line 15 to an exit 16 be pumped. The exit 16 can be connected to a suitable drain of a domestic installation or the like.

In the intake line 4a is a vapor barrier device 17a educated. This is in a curved line section 18a of the intake line 4a educated. The vapor barrier device 17a is formed by a water supply device.

Like the illustration in 1 further shows, is the intake line 4a at the feed point 11a to the tub 2 opening, on the other hand, at the confluence 20a the dispenser tray 8a the flushing arrangement 8th empties.

In addition, a second intake line 4b provided in the embodiment, which also has a line section 18b in which a curved upper portion is formed. Again, a vapor barrier device 17b designed. About the line 9b is about another junction 20b in the dispenser tray 8a a connection between the dispenser tray 8a and the further intake line 4b educated. The additional intake line 4b on the other hand flows at a feed point 11b to the cuff 10 that is between the tub 2 and the drum 3 located.

In the exemplary embodiment it is provided that the intake line 4b without a specific ventilation duct, as in the intake manifold 4a is provided, is formed.

The pipe section 18a will be explained in more detail with reference to the following figures.

In 2 is a perspective view of the intake strand 4a with the line section 18a shown. The pipe section 18a has a first upper end 19 on which with a connecting piece 20 the dispenser tray 8a connected is. At this upper first end 19 opens a feed channel 21 and separated from it a ventilation duct 22 , At this first end 19 are these two channels 21 and 22 To connect with continuations to opening and beyond also designed separately from each other.

The pipe section 18a , which in the embodiment of the intake line 4a represents is a one-piece injection molded part. It is predominantly rigid and has only in a middle section a flexible channel section 23 on, which is formed as a corrugated tube.

In 3 is a partially sketched as a sectional view view of the line section 18a according to 2 shown. As from the illustration in 2 to 4 It is obvious that this is the first end 19 the ventilation duct 22 not completely circulating around the feed channel 21 trained, but designed in this respect only partially circulating. The ventilation duct 22 is from the feed channel 21 through a boundary wall 24 separated.

As from the illustration in 3 it can be seen, is the first end 19 in terms of altitude, a level considered a lower end.

The ventilation duct 22 flows with his the upper end 19 opposite lower end 25 in the curved feed channel 21 ,

A related point of entry 26 is designed to be higher in level than a liquid level 27 in the feed channel 21 , Due to the design of a boundary wall 24 and the liquid level 27 , which extends over the lower end of the boundary wall 24 extends, the vapor barrier is formed. This liquid level 27 lies at the level below the confluence point 26 , A problem-free removal of the process air 28 , which is represented by the corresponding arrow, can thus via the intake line 4a and the ventilation duct 22 in the dispenser tray 8a respectively. On the other hand, the liquid medium 29 in the form of the fresh water and an optionally added detergent according to the arrow diagram shown by the dispenser 8a over the pipe section designed as a curved pipe section 18a to the feed point 11a be encouraged.

As well as in 3 can be seen, is the flexible channel section 23 in the feed channel 21 trained and thus after the confluence 26 of the ventilation duct 22 arranged. As well as out 3 it can be seen, is also the point of confluence 26 considered in terms of level above a kink area 32 of the feed channel 21 arranged, this kink area 32 following the bend of the feed channel 21 , in which bend the vapor barrier is formed, is arranged. Even if a corresponding spillover of the liquid over this kink area 32 takes place or the liquid level 27 up to this kink 32 would increase, is still the easy ventilation process through the ventilation duct 22 allows. This ventilation duct 22 then opens, as already mentioned, in a ventilation duct not shown in detail in the dispenser 8a , where the venting channel is then guided so that it contacts a boundary wall, which limits the volume range in which the liquid medium is contained. As a result, the process air is led along as long as possible to a condensation area and then from this back to the front, in particular from the front of the dispenser tray 8a then be able to escape.

In 4 is a perspective top view of the upper first end 19 to recognize. The outlet relationship or opening region of the ventilation duct formed in this illustration as a ring section 22 can be seen.

In 5 is an embodiment of the Einspülanordnung in a perspective view 8th with the induction bowl 8a shown.

The induction bowl 8a includes a top 8b and a lower part 8c , which are made as separate parts, for example as a one-piece injection-molded parts, and are connectable to each other, for example, are latched.

In the dispenser bowl 8a is in the lower part 8c a water supply device 8d formed with a water receiving trough. The water receiving trough is in the present embodiment as shown in FIG 7 , which shows a sectional view in the xz-plane, a siphon.

At the bottom 8c is a spout 8e formed, on which the line section 18a over the line 9a is connectable.

At another outlet 8f , the bottom part 8c is integrated, then the line section 18b over the line 9b connected.

As from the illustration in 5 it can also be seen in the outlet nozzle 8e and in a further continuation a venting channel 8g formed here, wherein the representation is shown partially broken away, so that in the interior of the channel 8g can be seen. In the connected state of the line section 18a at the outlet 8e then goes over the ventilation duct 22 the air according to the arrow direction shown 30 in the ventilation channel 8g in the dispenser tray 8a guided. This is from a front end of the dispenser tray 8a where the spout is 8e is formed, over the entire depth (y-direction) led backwards, and from there again forward and a front opening 8h from the dispenser tray 8a blown out.

In the illustration according to 6 It can be seen that the very narrow venting channel 8g through a boundary wall 8i is limited to the inside. This wall 8i is also at the same time the boundary wall of a water storage room 8j in the lower part 8c , The water therein, which optionally also has a detergent, is then supplied via the feed channel 21 to the tub 2 directed.

Due to the specifically designed and arranged ventilation duct 8g the air is as long as possible in the area of the water receiving space acted upon by the liquid 8j passed, so that a corresponding condensation can take place.

The embodiment of the dispenser tray 8a is also provided so that in the lower part 8c a subchannel 8k is formed, which with a further sub-channel in the upper part 8b the closed entire venting channel 8g forms.

In addition, it is envisaged that the upper part 8b a guide wall, not shown, through which in the assembled state of the upper part 8b with the lower part 8c an interior of the dispenser tray 8a in two flushing channels 8l and 8m is divided. A first flushing channel 8m is designed with the water supply device as a vapor barrier. A second flushing channel 8l is with a water supply device as a connection to the tub 3 educated.

In the already mentioned illustration in 7 is the design of the siphon 8n trained and broken illustrated water supply device 8d shown. This is in the lower part 8c integrated.

For easier production of the lower part 8c as a one-piece injection molded part is initially provided that only the water well is formed. To create the siphon then a partition 31 as a one-piece separate component manufactured and provided, which then in the lower part 8c can be used in the field of water well, in particular there is latching positionable. In 7 is the already positioned final state of this partition 31 shown, whereby then the siphon-like configuration of the water well of the water supply device 8d results in and according to the arrows shown in 7 the flow path of the liquid medium is shown.

In 8th is shown to a side view, where the partition 31 is taken. With such an embodiment of the dispenser tray 8a is also a very specific water supply system designed for flushing, which process reliably the escape of steam from the tub 3 prevented during the washing and drying cycle. This is done via the water reservoir in the integrated siphon 8n in the dispenser tray 8a ,

Runs water from the dispenser tray 8a to the cuff between the tub 2 and the drum 3 , so the said water supply system is completely flooded. Water flows through the channel.
