Description

The invention relates to a washing device and a household laundry care appliance with a washing tray containing an upper part and a lower part connected to it, wherein a water supply device with a chute for receiving water is provided in the lower part, an outlet pipe opening in a chute for receiving water, and a siphon located between the outlet pipe and the compartment for receiving water.

DE 10 2006 029 953 A1 discloses a washing machine with a controlled supply of clean water to at least two detergent chambers. In the upper part of the washing machine housing there is a device for washing off detergent. From the uneven bottom of the housing of this device for washing the detergent downward, pipelines for supplying the detergent, connected to the inlet on the cuff, on the one hand, and the inlet on the washing solution tank, on the other hand, go down.

Such a device for washing detergent allows the ventilation of the tank for washing solution without an additional ventilation pipe, and the presence of two separate pipelines for supplying detergent and their connection with the uneven bottom of the housing of this device for washing detergent ensures that one of these two pipes will always be is free.

DE 10 2004 060 709 A1 discloses a washing device with a water supply for a washing machine. The flushing tray of the flushing device comprises an upper part and a lower part, the lower part comprising an outlet pipe and a chute serving as a hydraulic shutter. In the water contained in the gutter, a baffle is lowered from above, dividing the lower part together with the water contained in the gutter and the vapor barrier formed in this way into two separate compartments. The partition is made integrally with the lower part or, preferably, with the upper part. As a result, the manufacture of components becomes very complex and difficult, especially if they are made by injection molding. The outlet of the washing device is connected to the washing solution tank of the washing machine.

The vapor barrier can be filled with water at most until it is bypassed at the outlet. In the event of vibration and pressure changes possible when opening the loading hatch of the washing machine, water may undesirably flow from the vapor barrier into the washing solution tank. This effect is undesirable, in particular, at the end of the washing cycle, since as a result, already wrung laundry will be wet again. This must be prevented, first of all, in the case when the outlet pipe is connected to a cuff located on the washing solution tank for direct wetting of the laundry.

An object of the present invention is to provide a washing device and a household laundry care appliance in which, in particular, when opening and closing the loading opening of a household appliance, unwanted wetting of the laundry with liquid from the water supply device or from the vapor barrier is prevented. In addition, the flushing device should be characterized by a compact design of fluid supply, on the one hand, and ventilation, on the other hand, as well as ease of manufacture.

This goal is achieved thanks to a flushing device and household appliance with the features disclosed in the independent claims.

The claimed washing device for a household appliance for washing includes a washing tray containing an upper part and a lower part, which can be connected to the upper part, and in the lower part there is a water supply device with a chute for receiving water and an outlet pipe opening into the chute for receiving water. In addition, between the outlet pipe and the water receiving compartment provided in the lower part, a siphon is made comprising a first bypass leading to the outlet pipe and a second bypass leading to another outlet, in particular to the second outlet pipe, the level of the first bypass (first overflow level) is higher than the second bypass level (second overflow level). An advantage of such a construction according to the invention is that when the siphon is completely filled with liquid, in the event of vibrations or pressure fluctuations, the liquid can flow out of the siphon through a second bypass to the second outlet. This allows you to effectively prevent the escape of fluid from the siphon through the first bypass to the outlet pipe. This is especially advantageous if the outlet pipe is connected to an opening located on the washing solution tank of the household appliance or on a cuff mounted on the washing solution tank, and the liquid flow exiting the opening directly moistens the laundry located in the drum of the household appliance . In this case, using the claimed design, it is possible to avoid unwanted wetting of the laundry liquid from the siphon.

Preferably, a bypass channel is located between the water supply device and the additional outlet, the cross-sectional area of which is less than the cross-sectional area of the outlet pipe, the bypass channel being located below the level of the first bypass. In a particularly preferred embodiment, the second bypass is formed by a bypass channel. The cross-sectional area of the bypass channel, in particular, is selected so that during flushing, water or liquid entering the flushing device essentially passes through a siphon and a first bypass at the outlet. At the same time, the cross-sectional area of the bypass channel should be so small that water or liquid at the flow rate set for the flushing process could not completely leak out through the bypass channel. This will lead to a rise in the level of water or liquid in the siphon and leakage of water or liquid through the first bypass from the outlet pipe upon reaching the first level of overflow. Thus, during the flushing process, it is possible to control, for example, the outflow of the supplied water or liquid from the outlet or additional outlet by changing the flow rate.

In particular, the washing device comprises a first and second outlet pipe, the first outlet pipe being connected to the first bypass, and the second outlet pipe to the second bypass, that is, the second outlet pipe serves as an additional outlet.

Preferably, the partition is made separately from the bottom, can be installed on the bottom and, when installed, forms a siphon between the outlet pipe and the compartment for receiving water. This design simplifies and reduces the cost of manufacturing the lower part in the form of a single part. In particular, in the manufacture by injection molding, the manufacture and molding of a siphon is extremely complex, fraught with errors. This production problem is solved by performing a partition in the form of a separate element and then installing the partition with the possibility of non-destructive removal, while maintaining the desired siphon configuration.

In a particularly preferred embodiment, the partition can be fixed to the lower part. As a result, very fast and accurate installation becomes possible, and the partition can be easily removed again.

Preferably, the lower part comprises a portion of the ventilation duct integrated in the flush tray, which extends into the outlet pipe. This configuration of the flushing tray allows the implementation of a vapor barrier with a high degree of integration, on the one hand, and appropriate ventilation, on the other hand. In the framework of the invention, a vapor barrier is understood to mean a substantially U-shaped pipe system, the portions of the pipe system communicating with each other can be filled with liquid medium to a level at which the passage of the gaseous medium will be impossible. A vapor barrier is effective if the pipe system is filled to this level. The pipe system may also have a shape different from the U-shape, provided that communicating with each other sections of the pipe system are able to create a vapor barrier of the same effect.

Preferably, the portion of the channel is bounded by a wall that simultaneously serves as the bounding wall of the compartment for receiving water in the wash tray. This contributes to the compact design. In particular, the result is a particularly preferred condensation of the gaseous medium directed through the ventilation duct.

Preferably, the channel section extends substantially along the entire length of the water receiving compartment in the lower part of the wash tray.

In particular, the channel section is closed by the second channel section in the upper part when the lower part is connected to the upper part.

In particular, the ventilation duct extends from the front end of the lower part, on which the exhaust pipe is located, to the rear end of the lower part and then up to the upper part, from where it goes back to the front end and exits into the outlet. As a result, it becomes possible to realize a particularly long path for the gas stream to pass through the flushing tray, and the gas stream, in particular, moves along a particularly long path in the water receiving compartment. This is especially advantageous for achieving the desired condensation.

In a preferred embodiment, the partition is made separately from the lower part and can be installed on the lower part, and in the installed state forms a siphon between the outlet pipe and the chute for receiving water.

In a preferred embodiment, the upper part comprises a guide wall, which, after installing the upper part on the lower part, divides the interior of the flush tray into two flush channels.

In particular, the first flush channel with a water supply device is made in the form of a vapor barrier.

Preferably, the second flush channel with a water supply device is made in the form of a connection to a washing solution tank of a household appliance.

In addition, the invention also relates to a household appliance for the care of linen, in particular, to a washing machine or washer-dryer containing a washing device according to the invention or one of its preferred embodiments.

Preferably, the household laundry care appliance comprises a wash tray and a washing solution tank connected to the wash tray by at least one supply pipe. In particular, a liquid medium, in particular water with a detergent, is supplied via a supply pipe to the cuff or tank for the washing solution. A vapor barrier is provided on the curved section of the supply pipe. A ventilation duct is provided at the pipeline section, which exits at the first end of the pipeline section. At the first end, this ventilation channel is separated from the supply channel related to the vapor barrier and designed to supply liquid medium from the wash tray to the washing solution tank. Thus, a section of the pipeline is made, at the first end of which there is a ventilation channel and a supply channel, and at this first end both of these channels are still separated from each other. Thus, two different channels are integrated into this section of the pipeline, which are still separated from each other, and as a result an extremely compact design that requires minimal installation space is obtained. As a result, a section of the pipeline is also connected to the specified first end, containing two channels. The connection of two separate channels is no longer required, since the connection is carried out only through this first end. Thus, a pipeline section was created containing an integrated multi-pass system, and for this, the water supply system and the duct system are implemented in one element. For this, separate channels for air and water are made at the front end. Thus, a vapor barrier is provided in the water supply system to prevent steam or condensate from escaping from the washing solution tank. In addition, ventilation in the cold water supply area in the flushing tray is functionally implemented due to the warm process air. This allows you to equalize the temperature and prevent condensation of water. In this case, vapor leakage from the loading device formed by the washing solution tank and the drum is effectively prevented.

In a preferred embodiment, the first end of the pipeline section is the upper end in terms of its level. As a result, the concept of a vapor barrier, on the one hand, and ventilation, on the other hand, can be achieved in a particularly reliable manner, and the possibility of a particularly simple connection to a washable chute will be retained.

In a preferred embodiment, the ventilation duct partially surrounds the supply duct at the first end. Considering that the ventilation duct does not completely surround the supply duct, a design is realized that is distinguished by special mechanical stability and particularly precise positioning of the ventilation duct and the feed duct. In particular, the ventilation can be positioned with high accuracy at the first end, and it is possible to ensure special accuracy and tightness of the transition into the wash tray and the ventilation duct located therein.

In a preferred embodiment, the ventilation duct enters the supply duct at the point of attachment, the attachment point being higher than the liquid level in the feed duct in which the vapor barrier is provided. Thus, this point of attachment is formed at the end of this ventilation duct, remote from the first end of the pipeline section, and thereby in a place shifted inward at the pipeline section.

In a preferred embodiment, the supply channel after the point of attachment of the ventilation channel contains a flexible section, made in particular in the form of a corrugated pipe. This configuration allows a portion of the pipeline or the supply pipe, made otherwise, in particular, rigid, to give some reversible possibility of deformation, thereby eliminating the risk of damage caused by the movement of the system during operation of the household appliance.

In a preferred embodiment, the feed pipe is made as a single element in the form of the pipeline section itself, in particular, by injection molding.

This feed hose or this pipe section connects the loading device with the wash tray and the detergent dispenser with the washing solution tank. At the same time, the indicated section of the pipeline also solves the problem of transporting process water to the washing solution tank. Due to the dynamic movements of the washing unit or the oscillating system, compensation is provided for the movement of this section of the pipeline, in particular due to the flexible corrugated section or the aforementioned flexible channel section.

A specific section of the pipeline simultaneously transports heated process air to the condensation region in the hydraulic feed device. The design feature is that the duct is integrated into the pipeline section, but the air passes through a channel separated from the water channel. The return of air through the water channel is excluded due to a specific hydraulic shutter. The required flow area of the duct is achieved, in particular, due to the eccentric location of the pipe in the pipe. This allows you to implement a concept that is particularly compact and easy to attach, as well as mechanical stability and durability.

Preferably, the internal and external connecting pipes are sealed with special sealing elements or sealing ribs. The hose can also be secured with suitable clamps on the outer pipe.

Identical or functionally identical elements are denoted by the same reference numbers.

In FIG. 1, a washing machine is shown as a plumbing appliance 1 for treating laundry. However, the household appliance 1 may also be a washer-dryer.

The household appliance 1 comprises a washing solution tank 2, in which a drum 3 is arranged for laying laundry, capable of rotating about an axis of rotation perpendicular to the plane of the figure.

In addition, the household appliance 1 comprises a first supply pipe 4a, through which clean water can be supplied to the drum 3. In addition, connection 5 is provided, which can be connected to a domestic water supply system or other similar system. From connection 5, the clean water pipe 6 leads to the inside of the household appliance 1. A shut-off valve 7 is activated in the clean water pipe 6, activated, for example, by a control system in accordance with a recorded program, for example, a pouring process program for wetting laundry. The clean water pipe 6 leads through a free air gap into the wash tray 8a of the washing device 8. In the wash tray 8a there can be, for example, a laundry treatment means, in particular a detergent, which is washed with clean water through the pipe 9a of the supply pipe 4a.

A household appliance 1 comprises a flexible cuff 10 connected to a washing solution tank 2.

As shown in FIG. 1, a first supply pipe 4a exits to a first supply point 11 to a washing solution tank 2. The nozzle of the supply pipe 4A is included in the tank 2 for washing solution at this point 11 of the supply. Thus, the supply line 4a also allows clean water and, possibly, a mixture of clean water and laundry treatment means to be supplied to the drum 3.

In addition, the household appliance 1 contains a pump out line 12, containing a shutter 13, a pump out 14 and a pipe 15. With the shutter 13 open, the washing solution in the washing solution tank 2 is pumped out through the pipe 15 to the outlet 16 by means of a pump 14. this outlet 16 may be connected to a suitable drain of a household sewer network or other similar device.

A vapor barrier 17a is provided in the supply line 4a. It is located in the bent portion 18a of the supply pipe 4a. The vapor barrier 17a is formed by a hydraulic valve.

As shown in FIG. 1, the supply pipe 4a enters the washing solution tank 2 at a supply point 11a, and on the other hand, a wash tray 8a of the washing device 8 is connected to the inlet 20a.

In addition, in this embodiment, a second supply pipe 4b is provided, which also comprises a pipe section 18b in which an upper curved section is provided. This pipe also has a vapor barrier 17b. A conduit 9b and an additional inlet 20b in the flushing tray 8a form a connection between the flushing tray 8a and the second supply pipe 4b. The other side of the supply pipe 4b is connected to a feed point 11b on the cuff 10 located between the washing solution tank 2 and the drum 3.

In this embodiment, the supply pipe 4b does not have a separate ventilation duct provided in the supply pipe 4a.

In FIG. 4, a top first end 19 is shown in a perspective view from the top. The figure shows the region of the outlet or opening of the ventilation duct 22, made in the form of an annular section.

In FIG. 5 is a perspective view illustrating an embodiment of a flushing device 8 with a flushing tray 8a.

The wash tray 8a comprises an upper part 8b and a lower part 8c, which are made in separate parts, for example, by injection molding, and can be connected to each other, for example, fixed to each other.

In the lower part 8 of the flushing tray 8a, a water supply device 8d is provided with a chute for receiving water. The chute for receiving water in this embodiment is a siphon, as shown in FIG. 7, which shows a section AA of the washing device 8, made in the x-z plane.

An outlet pipe 8e is made in the lower part 8c, which can be connected via the pipe 9a to the pipe section 18a.

To the next outlet pipe 8f integrated into the lower part 8c, a portion 18b can be connected via a conduit 9b.

As shown in FIG. 5, a ventilation duct 8g is provided in the exhaust pipe 8e and in a further extension, and a partial section allows you to see the inside of the channel 8g. In addition, the flush tray 8a is configured in such a way that in the lower part 8c there is a channel section 8k, which together with another channel section in the upper part 8b forms a complete closed ventilation duct 8g.

In addition, the upper part 8b includes a guide wall not shown in the figure, which, after installing the upper part 8b on the lower part 8c, divides the interior of the flush tray 8a into two flush channels 8l and 8m. The first flush channel 8m together with the water supply device is made in the form of a vapor barrier. The second flush channel 8l together with the water supply device is made in the form of a connection to the tank 3 for washing solution.

In FIG. 7 shows the already mentioned water supply device 8d, made in the form of a siphon 8n and shown partially in section. It is integrated into the bottom of 8c.

To simplify the manufacture of the lower part 8c, only a water chute is initially provided as a solid cast part. To form a siphon, a partition 31 is used, which is manufactured as a separate integral part and can subsequently be installed in the lower part 8c in the region of the water chute, in particular, can be placed in it with fixation. For this, in FIG. 7 shows the installed baffle 31 in the final state, as a result of which the water chute of the water supply device 8d takes the form of a siphon. The path of the fluid is shown by arrows in FIG. 7.

In FIG. 8 is a side view in which the partition wall 31 is removed. In this configuration of the wash tray 8a, a specific hydraulic shutter for flushing is implemented that reliably prevents steam from leaking from the washing solution tank 3 during the washing and drying step. This is realized by a hydraulic shutter in the integrated siphon 8n in the flush tray 8a.

In FIG. 9 shows a section B-B of the flushing device 8 in the x-z plane, which shows the water supply device 8d with a tray for receiving water filled with a locking medium 33, in particular water or liquid, up to the overflow level 34 of the second bypass. If now the water supply device 8d will additionally supply water or other liquid, then it will flow through the second bypass along arrow 36 to the discharge pipe 8e, since the second bypass overflow level 34 is lower than the first bypass overflow level 35.

A bypass channel 38 is located between the outlet 8e and the water supply device 8d. As shown in FIG. 9, the bypass channel is in the second bypass region. The bypass level is below the first overflow level 34. If now the water supply device 8d will supply more water or liquid per unit time than it can drain through the bypass channel 38, then the level of the locking medium 33 in the water supply device 8d will rise. When the level of the locking medium 33 reaches the first overflow level 35, water or liquid supplied to the locking medium 33 will drain through the outlet 8f. Since the cross section of the bypass channel is smaller than the cross section of the outlet pipe 8f, more water or liquid from the washing device 8 will flow through the outlet pipe 8f than through the outlet pipe 8e.

During operation of the washing machine 1 in this embodiment, direct wetting of the laundry should be carried out only during washing. In this case, water or liquid flows from the wash tray 8a to the cuff 10 between the washing solution tank 2 and the drum 3, as a result of which the liquid flows through the entire hydraulic shutter system, in particular the vapor barrier 17b. In this case, water or liquid flows through pipelines 9b and 18b.

In this embodiment, the cross section of the bypass channel 38 is aligned with a predetermined flow of water or liquid so that during the flushing process, water entering through the connection 5 essentially flows through the outlet 8f and the leakage through the bypass channel 38 is negligible. Thus, for example, during the washing process, the laundry can be directly wetted in the washing machine 1, since in this embodiment, the discharge pipe 8f is connected by a pipe 9b to a supply point 11b, and the supply point 11b directs the water or liquid flowing therefrom directly to the drum 3 and thereby on the laundry.

Water or liquid remaining in the water supply device 8d forms a vapor barrier or siphon. However, during the operation of the washing machine 1, the rest of the time, the locking medium 33 is set in motion due to vibrations or vibrations of the household appliance or pressure fluctuations, in particular when opening and closing the loading hatch of the washing machine 1. Such a movement is shown in FIG. 9 by arrow 37. The movement of the locking medium 33 causes it to splash out, as a result of which part of the locking medium 33 will flow out through the lower bypass, that is, the second bypass. This part will then drain through the bypass channel 38 and the exhaust pipe 8e into the pipe 9a. As shown in FIG. 1, the conduit 9a is connected to the washing solution tank 2 and is not connected to the cuff 10, which avoids undesirable wetting of the laundry with the locking medium 33 during such splashing. Therefore, it is possible to prevent re-wetting of the laundry with the locking medium 33 flowing out of the water supply device 8d when opening the loading door and removing the already wrung laundry, which can lead to pressure fluctuations in the hydraulic shutter system.

The pipeline section 18a is described in detail below. The washing machine 1 and its control system are designed so that during the washing process, water or liquid can be supplied through the pipe section 18a or the pipe section 18b to the washing solution tank 2 or drum 3.

In FIG. 2 is a perspective view of a supply pipe 4a with a pipe portion 18a. The pipe section 18a has a first upper end 19 connected to the connecting pipe 20 of the flushing tray 8a. Into this first upper end 19, a supply duct 21 and a ventilation duct 22 separate from it emerge. Thus, at this first end 19, both of these ducts 21 and 22 converge to connect with their extensions, but remain separated from each other.

The pipe section 18a, which in the shown embodiment depicts the supply pipe 4a, is an integral cast piece. It has a predominantly rigid structure, and only in the central part contains a flexible section 23, made in the form of a corrugated pipe.

In FIG. 3 is a partially sectional view of the pipe section 18a of FIG. 2. As shown in FIG. 2-4, at this first end 19, the ventilation duct 22 does not completely surround the supply duct 21, but only partially. The ventilation duct 22 is separated from the supply duct 21 by a restrictive wall 24.

As shown in FIG. 3, the first end 19 is the upper end in terms of level.

The lower end 25 of the ventilation channel 22, remote from the upper end 19, extends into the curved feed channel 21.

The corresponding point of attachment 26 is located above the liquid level 27 in the supply channel 21. The configuration of the restriction wall 24 and the liquid level 27 exceeding the level of the lower end of the restriction wall 24 make it possible to create a vapor barrier. Fluid level 27 below attachment point 26. Thus, the supply air 4a and the ventilation duct 22 can easily exhaust the process air 28 into the wash tray 8a, as shown by the corresponding arrow. On the other hand, a liquid medium 29, consisting of pure water and possibly detergent added to it, can be guided in accordance with the arrow shown from the flushing tray 8a along the pipe section 18a, made in the form of a bent pipe, to the supply point 11.

In addition, in FIG. 3 it can be seen that the flexible section 23 of the channel is formed in the supply channel 21 and, thus, is located after the connection point 26 of the ventilation duct 22. In addition, in FIG. 3 it can be seen that the attachment point 26 is located above the bend 32 of the supply channel 21, and this bend 32 is located behind the bend of the supply channel 21, in which a vapor barrier is formed. Even if the liquid will accordingly splash through this bend 32, or the level 27 of the liquid rises to this bend 32, ventilation can be carried out without problems through the ventilation duct 22. This ventilation duct 22, as already mentioned, goes into the ventilation duct of the wash tray 8a, not shown in detail, moreover, the ventilation duct is laid there in such a way that it is in contact with the restrictive wall bounding the area with the liquid medium. Thus, the process air flows along the condensation region for the longest possible time, after which it is again directed forward, in order to then exit, in particular, on the front side of the wash tray 8a.

Furthermore, as shown in FIG. 5, when the pipe portion 18a is connected to the exhaust pipe 8e by the ventilation duct 22, air flows in the direction 30 indicated by the arrow into the ventilation duct 8g in the flush tray 8a. In this case, air is directed from the front end of the flushing tray 8a, on which the outlet pipe 8e is made, to the entire depth (direction y) back, and from there forward again, and is discharged through the front opening 8h from the flushing tray 8a.

In FIG. 6 shows that a very narrow ventilation duct 8g is delimited on the inside by a restriction wall 8i. This wall 8i simultaneously serves as the boundary wall of the water receiving compartment 8y in the lower portion 8c. The water contained therein, which may also contain detergent, is then sent through the supply channel 21 to the washing solution tank 2.

Due to the specific design and location of the ventilation duct 8g, the air moves for as long as possible in the area of the compartment 8u for receiving water filled with liquid, which allows the corresponding condensation to be realized.
