Description

The present invention relates to a laundry care machine, in particular a washer-dryer.

Usually there is a siphon on a detergent dispenser in a laundry care machine which is filled with water during operation and thus separates the atmosphere inside the machine from the atmosphere outside the machine. This generally prevents hot, humid air from escaping or from escaping from the machine via the detergent dispenser during washing, in particular boiling laundry at 90 ° C. Such a separating effect of the siphon is also necessary in a washer-dryer, since vapors with process air temperatures of over 100 ° C occur precisely during a drying process, which must not get into the detergent bowl, and an uncontrolled escape of moist process air is otherwise undesirable.

It is known that at high speeds such as spinning from approx. 1200 revolutions per minute and depending on the load inside the drum, a negative pressure occurs which empties the siphon. As a result, air is constantly drawn in through the siphon during the spinning process.

With a pure washing machine, this behavior is usually not a problem, since the washing process is completed with the spinning. In the case of a washer-dryer, however, a drying process is usually carried out immediately after a spin phase, in which case the siphon can be open during the entire drying process. In this case, hot, moist air can escape into the detergent bowl and out of the machine.

The DE 10 2008 019 388 A1 describes a washer-dryer with a tub and a laundry drum rotatably arranged therein for receiving laundry, a water inlet line and a water drain line, and a ventilation duct which connects the tub with the surroundings of the washer-dryer. Further state of the art is off DE 10 2011 053 950 A1 and WO 2011/032951 A1 known.

The present invention is based on the object of providing an improved laundry care machine. In particular, it is an object of the present invention to provide a laundry care machine which, during a drying process, reliably prevents hot, moist air from being able to escape from the machine via the dispensing bowl and the bowl handle.

These objects are achieved with a laundry care machine according to the independent patent claim. Advantages and features of preferred optional embodiments of the invention emerge from the dependent claims, the following description and / or the figures of the accompanying drawings.

Accordingly, the laundry care machine according to the invention has a dispensing bowl for introducing a detergent, a tub and a drum rotatably arranged therein for receiving laundry. A laundry care machine can preferably be a washing machine, a tumble dryer or, particularly preferably, a washer-dryer. Furthermore, the laundry care machine can have a water inlet line for introducing washing water into the dispenser and a water drainage line for discharging the washing water from the tub. Furthermore, the laundry care machine has a detergent solution channel which connects the dispenser and the detergent solution container. The wash liquor duct has a siphon with a ventilation duct wall and a peripheral wall, the wash liquor duct having an additional ventilation duct through which air can flow into the tub when the siphon is full when a negative pressure is formed in the tub. Through the additional ventilation channel, which can be arranged in the siphon, for example, air can flow into the tub during spinning without the liquid in the siphon being completely sucked out of the siphon by the pressure gradient into the tub. The additional ventilation channel leads to a reduction in the negative pressure in the laundry drum or the tub. In particular during a spinning process, an air flow can be directed via the additional ventilation duct in the direction of the washing solution duct, which leads to the lye container, in order to produce a pressure equalization. The fact that an additional ventilation duct is provided prevents the siphon from emptying so completely during spinning that the separation between the atmospheres inside and outside the machine would be canceled.

According to the invention, the additional ventilation duct has a ventilation duct wall along a contour of the siphon, the ventilation duct wall having an inlet for letting air into the additional ventilation duct and an outlet for letting out air from the additional ventilation duct, in particular when spinning. The outlet of the additional ventilation channel is preferably at a greater distance from the bottom of the siphon than the inlet of the additional ventilation channel. In particular in relation to an orientation of the siphon, the inlet is arranged below the outlet. The inlet is preferably in the first area, the outlet in the second area, with the inlet being exposed by the falling water level in the first area when a negative pressure is formed in the tub. The outlet in the second area should be arranged so high that it is still exposed when the liquid has been displaced so far into the second area that the inlet of the additional ventilation channel is exposed. The pressure can then be equalized and there is no further displacement of the liquid from the first to the second area.

According to the invention, the ventilation duct wall of the additional ventilation duct and a circumferential wall of the siphon are dimensioned such that a supply of liquid remains in the siphon during spinning, which after spinning closes the siphon airtight. During a spin, this supply is displaced into the second area of the siphon, with a water column building up in the second area which is designed to be significantly larger than a water column in the first area and / or in the additional ventilation duct. The negative pressure generated in the laundry drum during spinning consequently leads to the liquid in the siphon being shifted into the second area, whereby the additional ventilation channel or its inlet is at least partially exposed, so that air flows into the laundry drum via the additional ventilation channel can.

The additional ventilation channel is preferably arranged on or in the siphon. This allows the additional ventilation duct to be produced in a simple manner. At the same time, the siphon water can be used to close the additional ventilation duct when there is no negative pressure in the tub, as will be explained in more detail below.

The additional ventilation channel is preferably designed and / or arranged on or in the siphon in such a way that the additional ventilation channel when a formation is spun a negative pressure in the tub, ie an internal drum pressure P _i , counteracts, but preferably does not completely prevent the formation of the negative pressure in the tub. Rather, the creation of the negative pressure in the tub is reduced so that emptying of the siphon can be avoided, but sufficient suction is created in the siphon during spinning so that the liquid remains in an area outside the additional ventilation duct.

According to a preferred embodiment, the additional ventilation channel is designed in such a way that, during spinning, the additional ventilation channel is exposed by a liquid located in the additional ventilation channel and the siphon due to the pressure dropping in the tub. This means that at the beginning of a centrifugal process, liquid is initially divided into a first area, in the additional ventilation channel and in a second area of the siphon. With increasing generation of the negative pressure during spinning, the liquid is shifted from the first area and the additional ventilation channel into the second area of the siphon. What is achieved hereby is that a column of liquid is formed much higher in the second area than in the first area and in the additional ventilation channel. This is achieved in particular when the internal drum pressure Pi is significantly lower than the ambient pressure P _u .

An embodiment of the laundry care machine is conceivable which has a siphon with a partition which divides the siphon into a first area and a second area. During a centrifugal process, the negative pressure generated in the tub moves the liquid in the siphon towards the second area, whereby the additional ventilation channel is at least partially exposed of liquid, so that an air stream flows from the first area via the additional ventilation channel into the tub can.

The siphon preferably has a first area and a second area, the additional ventilation duct being arranged between the first and the second area or in the second area. It is conceivable that the additional ventilation channel is formed parallel to a partition wall of the siphon, which divides the siphon into the first and the second area. Furthermore, the additional ventilation channel can have a ventilation channel wall which is at least partially into the partition wall transforms. The additional ventilation channel can be arranged between the partition wall and the second area in a partial area of the second area. It is also conceivable to provide the additional ventilation channel between the first and the second area as a connecting channel.

The first area directly or indirectly adjoins the dispensing bowl and the second area directly or indirectly adjoins the detergent solution duct. According to the solution proposed herein, the siphon is arranged in the wash liquor channel. In particular, a first area of the siphon is assigned to the detergent solution duct on the dispenser side and a second area of the siphon is assigned to the detergent solution duct on the detergent solution container side. Such an arrangement can prevent hot, moist air from escaping from the laundry care machine through the detergent dispenser.

It is conceivable that the additional ventilation channel runs between two walls, namely the ventilation channel wall and the partition wall, which each have a length. It is particularly advantageous that the ventilation duct wall and the partition wall have the same or a different length and / or have a different distance from a bottom of the siphon. The fact that the ventilation duct wall and the partition wall are at a different distance from the bottom of the siphon ensures that the liquid in the siphon can collect in the second area due to the negative pressure in the laundry drum during spinning and the additional ventilation duct is exposed. During a spin, the second area of the siphon is consequently filled with this liquid. The additional ventilation channel can be designed as a hollow cylinder with any type of cross-sectional area. The additional ventilation duct is particularly preferably designed as a hollow cylinder with a round, triangular, n-cornered or rectangular cross-sectional area.

The second area between the ventilation duct wall and the circumferential wall of the siphon preferably forms a water reservoir in which the liquid is displaced during a centrifugal process. During the spinning, the liquid is consequently displaced into the water reservoir, forming a water column in the water reservoir which preferably extends along a length, in particular an entire length, of the water reservoir. Through the ventilation duct wall Thus, on the one hand, an additional ventilation channel is provided during a centrifugal process, in which an air stream can flow into the interior of the drum. On the other hand, a water reservoir is formed, in particular in the second area, which is not occupied by the additional ventilation channel and in which the liquid is displaced during a centrifugal process. The water reservoir can hold a large part of the liquid. After completion of the spinning process, the liquid from the water reservoir, ie the second area, can flow back into the first area and into an area of the additional ventilation channel, so that the siphon is closed again.

The water reservoir preferably has a volume which takes up the liquid, so that the additional ventilation channel is exposed from the at least partially liquid, the volume in particular taking up the liquid essentially completely. The volume of the water reservoir is preferably sufficient to hold enough liquid to completely close the siphon again in the event of a pressure drop. It is conceivable that the liquid can be absorbed essentially completely by the volume of the water reservoir as soon as a negative pressure arises in the laundry drum during spinning. It is also conceivable that the volume of the water reservoir is dimensioned such that enough liquid can be absorbed by the volume until the additional ventilation channel is exposed, but part of the liquid remains in a bottom area of the first area of the siphon.

Preferably, the ventilation duct wall at the outlet partially merges into a wall of the dispensing bowl and ends partially spaced from the wall of the dispensing bowl and merges partially into a wall of the siphon at the inlet and / or ends partially spaced apart from a bottom of the siphon. The inlet is thus at a distance from the bottom of the siphon. This ensures that when the negative pressure arises in the tub, ie during spinning, the liquid in the siphon can flow off into the second area. If the siphon has a partition, such a partition can, for example, merge at one end into a wall of the dispensing bowl and can end at an opposite end at a distance from the bottom of the siphon. The fact that the partition wall ends at a distance from the bottom of the siphon ensures that an air flow can form in the additional ventilation duct during a centrifugal process.

The various embodiments of the proposed siphon for a laundry care machine as described herein, through their function, form a one-way valve. This means that air can flow into the laundry drum while it is being spun, but no air can escape from the laundry care machine during the drying process.

In the following, the Figures 1 , 3 to 6 a preferred new embodiment explained. The Figure 2 shows a siphon according to the prior art.

Figure 1 shows a schematic view of a laundry care machine 10 according to the prior art with a dispensing bowl 12 for introducing a detergent. The laundry care machine 10 according to Figure 1 is shown with the most important functional components which, according to current practice, are to be arranged in a housing, not shown here, and to be connected to a control device, also not shown, for the purpose of control according to predetermined programs.

The laundry care machine 10 comprises a tub 16 for receiving washing liquor for a washing process. A laundry drum 28 for receiving laundry 4 is arranged in the tub 16. A water supply line 5 to 10 is used to feed water or washing liquor to the tub 16. The water supply line 5 is to be connected to a water supply network and comprises a controllable water supply valve 6. The water supply line 5 opens into a dispenser housing 7, in which there is a pull-out dispenser bowl 12 for introducing Laundry care products such as detergent and / or fabric softener. From the dispenser bowl 12 and the dispenser housing 7, the water possibly mixed with laundry care products - then referred to as washing or rinsing liquor - passes through the washing liquor channel 9 into the tub 16. The washing liquor channel 9 comprises a siphon 18, which is particularly useful in washing processes that are relatively run at high temperature, serves as an odor barrier between the tub 16 and the environment of the laundry care machine 10. A water drainage line comprising a lye drainage line 11 connected to the tub 16, a lye pump 12 and a riser line 13, the riser line 13 leading out of the laundry care machine 10 and being connected to a sewage system, is used to drain the washing or rinsing water and anything at all Waste water, in particular after a washing process, provided. In the present case, known details of the connection of the liquor drainage line 11, for example a drain valve, are not shown. The laundry care machine 10 is equipped with the components mentioned so far for carrying out washing processes known per se for washing the laundry 4, the further explanation of which is unnecessary here.

In order to also be able to carry out drying processes for drying the laundry 4 with the laundry care machine 10, which is designed in particular as a washer-dryer, the laundry care machine 10 is equipped with a drying duct. The drying duct extends from an inlet 14 on the tub 16 to an outlet 19 on the tub 16 and comprises a dry air duct 15 between them for guiding dry air in a substantially closed circuit that includes the tub 16. Arranged in the dry air duct 15 are, inter alia, a condenser 23, a fan 17 and a heater 21. The circulating dry air is heated by the heater 21 and passes from the heater 21 through the outlet 19 into the tub 16 to remove moisture from the laundry 4 to record. The dry air laden with moisture then passes through the inlet 14 to the condenser 23, where it is cooled so that the moisture condenses out in liquid form. The condensate generated in this way returns to the tub 16 and is discharged from there through the water drainage line. The dry air freed from the moisture passes through the dry air duct on to the fan 17, which drives it in its circuit, and on to the heater 21, where it is heated again in order to get back into the tub 16 and the laundry 4.

The condenser 23 is shown as an air-cooled condenser 23, the heater 21 as an electric heater 21, as in fact corresponds to a preferred configuration of the washer dryer or the laundry care machine 10. Likewise preferred is a configuration of the washer dryer or the laundry care machine 10 in which the condenser 23 and the heater 21 are components of a heat pump in which the condenser forms a heat sink and the heater forms a heat source.

Figure 2 shows an enlargement of a dispensing bowl with a siphon 18 of a laundry care machine 10 according to the prior art. Figure 2 shows that the siphon 18 is divided into a first area 32 and into a second area 34 through a partition wall 30 is divided. According to the known siphon 18 from the prior art, the water from the siphon 18 is pressed into the tub during a spinning process by the negative pressure generated in the tub, and then an air stream 26 can reach the inside of the laundry drum 28 via the siphon 18. The water remaining in the siphon 18 is greatly reduced here. This allows hot, moist air to escape via the dispensing bowl 12 during a drying process.

The Figures 3 to 5 each show a possible embodiment of the new siphon 12 for the laundry care machine 10, the Figures 3a , 4a , 5a show the respective siphon in a closed state and the Figures 3b , 4b , 5b show the respective siphon in an open state.

Figures 3a, b show a detail of a laundry care machine 10 with a siphon 18 according to the invention in cross section. According to the proposal, the siphon 18 has an additional ventilation duct 44 with a partition wall 30 and a ventilation duct wall 46. Figure 3a shows the proposed siphon 18 in a state of rest, ie in a state in which no spinning process is being carried out. The water 42 in the siphon 18 is thus distributed over a first area 32, the additional ventilation channel 44 and a second area 34, the first area 32 of the dispensing bowl 12 and the second area being assigned to an additional ventilation channel 44 of the laundry drum 28. In this state, according to Figure 3a , the proposed siphon 18 is closed. In particular, in this state, an ambient pressure P _{u is} not significantly greater than the internal drum pressure P _i .

Figure 3b shows the siphon 18 according to Figure 3a in an open state. The open state refers to a state in which a spin process is being carried out. During a spin process, the internal drum _{pressure P i is} significantly lower than the ambient pressure P _u . This leads to the fact that the water 42 in the siphon 18 is predominantly displaced into the second area 34 of the siphon 18, which is separated by the additional ventilation duct 44 of the siphon 18. Only a small part of the water 42 remains in the first area and in a partial area of the additional ventilation channel 44. Again Figure 3b can be seen, the additional ventilation channel 44 of the siphon 18 is exposed during a centrifugal process, so that an air flow 26 from the first area 32 via the additional ventilation channel 44 of the Siphons to the additional ventilation duct 24 of the laundry drum 28 can be guided into the interior of the drum and leads to a pressure equalization.

Like that Figures 3a and 3b When viewed together, the additional ventilation channel 44 of the siphon 18 has, in addition to the partition wall 30, a ventilation channel wall 46. The partition wall 30 extends into a wall 48 of the dispensing bowl 12. The ventilation duct wall, on the other hand, has an exposed end at the top and bottom, while it merges into the partition wall 30 on the sides. The inlet 50 is at the lower end and the outlet 52 at the upper end. The inlet 50 of the additional ventilation duct 46 of the siphon 18 is spaced from a bottom 54 of the siphon 18. The outlet 52 of the additional ventilation duct 44 of the siphon 18 is spaced from a wall 48 of the induction bowl 12. The partition wall 30 and the ventilation duct wall 46 each have a length and extend offset from one another, so that the partition wall 30 and the ventilation duct wall 46 have a different distance from the bottom 54 of the siphon. According to the Figures 3a, 3b If the distance between the partition wall 30 and the floor 54 is greater than the distance between the ventilation duct wall 46 and the floor 54. This ensures that during a centrifugal process, i.e. in an open state, the water 42 from the first area 32 and the additional ventilation duct 44 can be passed into the second area 34. During a centrifugal process, the water column 56 in the second area 34 is formed much higher than a water column 58 in the first area 32 and in the sub-area of the additional ventilation channel 44. After the end of a centrifugal process, the water 42 from the second area 34 can return to the first Area 32 and flow back into the additional ventilation channel 44. This process would correspond to a transition from the open state Figure 3b in a locked state according to Figure 3a .

The Figures 4a, 4b and 5a, 5b each show a further embodiment of a siphon 18 according to the invention for a laundry care machine 10.

According to the Figures 4a, b the siphon 18 is formed with an additional ventilation channel 44, which is arranged between the first area 32 and the second area 34 as a connection between the first and second areas 32, 34. In the closed state ( Figure 4a ) the water columns 58, 56 in the two areas 32, 34 are designed to be the same height and the water 42 covers the inlet of the additional Ventilation channel 44, so that it does not let air through. In an open state ( Figure 4b ) the water column 56 in the second area 34 is larger or higher than the water column 58 in the first area 32. As a result, the water 42 is displaced from the additional ventilation duct 44 so that an air stream 26 can flow through it into the laundry drum 28 . As in the Figures 4a, b shown, the additional ventilation channel 44 runs here between the two legs of the U-tube which forms the siphon 18, and not directly in the siphon pipe.

According to the Figures 5a, b the siphon 18 is formed with an additional ventilation channel 44 which is formed inside the siphon 18. In this embodiment, the additional ventilation channel 44 is arranged in a transition from the first to the second area 32, 34. As in the Figures 5a, 5b shown, the additional ventilation channel 44 has a shape simulating a contour 60 of the siphon. The additional ventilation channel 44 has a ventilation channel wall 46. In an open state ( Figure 5b ) the water column 56 in the second area 34 is larger than the water column 58 in the first area 32. As a result, the water 42 has flowed out of the additional ventilation duct 44 so that an air stream 26 can flow through it into the laundry drum 28.

Figure 6 shows schematically a sequence of the steps before a spinning process S1, during a spinning process S2 and after a spinning process S3. Before a spinning process in accordance with step S1, the siphon 18 of the laundry care machine 10 is in a closed state (see FIG Figures 3a , 4a and 5a ). This means that water 42 is arranged both in the first area 32, in the additional ventilation duct 44 and in the second area 34. In particular, the water columns 56 and 58 extend in these areas at a uniform level, ie the water columns 58 and 56 are of the same size.

_{During a spinning process in step S2, a negative pressure P i is} generated in the drum interior of the laundry drum 28 of the laundry care machine 10, which causes the siphon water 42 to be displaced from the first area 32 and the additional ventilation duct 44 into the second area 34. Step S2 thus corresponds to a transition from the closed state according to FIG Figures 3a , 4a and 5a in an open state according to Figure 3b , 4b and 5b 4th . During this transition, the additional ventilation duct 44 is exposed, so that an air flow 26 over the first Area 32 and the additional ventilation channel 44 can flow to a ventilation channel 24 of the laundry drum 28 and a pressure equalization is made possible. In this state, the water column 58 in the first region 32 is made smaller than the water column 56 in the second region 34.

After the spinning process has ended, the water 42 can flow back from the second area 34 into the first area 32 and into a partial area of the additional ventilation channel 44. The step S3 thus corresponds to a transition from the open state according to FIG Figures 3b , 4b and 5b in a closed state according to Figures 3a , 4a and 5a .

After such a spinning process, a drying process can consequently take place in a laundry care machine 10, in particular a washer-dryer, without hot, moist air being able to escape into the dispensing bowl 12. The proposed siphon 18 for the laundry care machine 10 consequently acts like a one-way valve which can in particular assume two states, namely open and closed.
