Description

Washing machine with flushing shell and siphon seal

Technical Field

The invention relates to a laundry care machine, in particular a washing and drying machine.

Background

A siphon seal, which is filled with water during operation and thus separates the environment inside the machine from the environment outside the machine, is usually located on the wash-in housing in the laundry care machine. This generally prevents hot, moist air from escaping or escaping from the machine via the rinsing-in shell during washing, in particular during a cooking wash at 90 ℃. This separation of the siphon seal is also necessary in the washer dryer, since steam with a process air temperature of more than 100 ℃ occurs precisely during the drying process, which steam is not allowed to enter the wash-in housing, or else the moist process air flows out uncontrollably, which is also undesirable.

It is known that at high rotational speeds, for example at spin drying from approximately 1200 revolutions per minute, and in accordance with the load in the drum, a negative pressure is formed which evacuates the siphon seal. Accordingly, air is continuously resupplied through the siphon seal during the spinning.

In a washing machine only, this situation is usually not a problem, since the washing process ends with a spin-drying. In a washer dryer, however, the drying process is instead usually carried out immediately after the spin-drying phase, wherein the siphon seal is opened here during the entire drying process. In this case, hot, moist air can flush into the housing and escape from the machine.

DE 102008019388 a1 describes a washer-dryer having: a washing liquid container and a laundry drum rotatably arranged therein for receiving laundry; a water inlet line and a water discharge line; and an air duct connecting the washing liquid container with the environment of the washer-dryer.

Disclosure of Invention

The object on which the invention is based is to provide an improved laundry care machine. In particular, it is an object of the invention to provide a laundry care machine which reliably prevents hot, moist air from flowing out of the machine via the rinsing-in housing and the housing handle during the drying process.

The object is achieved by means of a laundry care machine according to the invention. Advantages and features of preferred and alternative embodiments of the present invention will become apparent from the following description and/or drawings.

The laundry care machine according to the invention therefore has: a flush-in housing for introducing a detergent; a container for a washing liquid; and a drum rotatably disposed in the washing liquid container for receiving the laundry. The laundry care machine can preferably be a washing machine, a laundry dryer or particularly preferably a washer-dryer. The laundry care machine can also have a water inlet line for introducing wash water into the rinsing housing and a water outlet line for discharging wash water from the wash liquor container. In addition, the laundry care machine has a washing liquid channel which connects the wash-in housing to the washing liquid container. The wash liquor channel is provided with a Siphon device or Siphon seal (sipon). According to the invention, the lotion channel has an additional air duct, through which air can flow into the lotion container when a negative pressure is formed in the lotion container when the siphon seal is filled. By means of an additional air duct, which can be arranged in the siphon seal, for example, air can flow into the washing liquid container during spin-drying, while the liquid located in the siphon seal is not completely sucked out of the siphon seal into the washing liquid container as a result of the pressure drop. The additional air duct causes a reduction in the underpressure in the laundry drum or in the liquor container. In particular during the spin-drying process, the air flow can be guided via an additional air duct in the direction of a washing liquid channel which opens into the washing liquid container in order to establish a pressure equalization. By providing additional air ducts: the siphon seal is completely emptied during the spin-drying so that the separation between the environment inside the machine and outside the machine is eliminated.

Preferably, the additional air duct is arranged on or in the siphon seal. This allows for simple manufacture of the additional air duct. At the same time, siphon water can be used to close the additional air duct when there is no negative pressure in the lotion container, as will be explained in more detail further below.

Preferably, the additional air duct is designed and/or arranged on or in the siphon seal in such a way that it prevents the formation of a negative pressure, i.e. the drum internal pressure P, in the liquor container during spin-drying _i But preferably does not completely prevent the formation of a negative pressure in the lotion container. More precisely, the formation of a negative pressure in the washing liquid container is reduced, so that emptying of the siphon seal can be avoided, while nevertheless sufficient suction is formed in the siphon seal during spin-drying, so that liquid remains in the region outside the additional air duct.

According to a preferred embodiment, the additional air duct is designed such that it emerges from the liquid located in the additional air duct and the siphon seal during the spin-drying operation as a result of the reduced pressure in the washing liquid container. This means that at the beginning of the spin-drying process, liquid is first dispensed in the first zone, the additional air duct and the second zone of the siphon seal. As the negative pressure builds up more and more during spin drying, liquid is displaced from the first region of the siphon seal and the additional air duct into the second region. This results in the formation of a liquid column in the second region which is significantly higher than in the first region and the additional air duct. Especially when the pressure P inside the drum _i Substantially less than ambient pressure P _u This is achieved.

One embodiment of a laundry care machine can be envisaged, which has a siphon seal with a partition wall, which divides the siphon seal into a first region and a second region. During the spin-drying process, the liquid located in the siphon seal is displaced towards the second region as a result of the negative pressure generated in the washing liquor container, whereby the additional air duct is at least partially exposed from the liquid, so that an air flow can flow from the first region via the additional air duct into the washing liquor container.

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

The first region is directly or indirectly adjoined to the flush housing and the second region is directly or indirectly adjoined to the wash liquor channel. According to the solution proposed here, a siphon seal is arranged in the washing liquid channel. The first region of the siphon seal is assigned in particular to the washing liquid channel running into the shell side, and the second region of the siphon seal is assigned to the washing liquid channel on the washing liquid container side. By means of this arrangement, it is possible to prevent hot, moist air from escaping from the washing liquid container through the rinsing housing from the laundry care machine.

It is conceivable that the additional air duct extends between two walls, i.e. between an air duct wall and a partition wall, each having a certain length. It is particularly advantageous if the air duct wall and the partition wall have the same or different lengths and/or have a different spacing from the base of the siphon seal. The air duct wall and the partition wall have a different distance from the bottom of the siphon seal, which means that the liquid in the siphon seal can accumulate in the second region during spin-drying as a result of the underpressure in the laundry drum and the additional air duct is exposed. Thus, during spin-drying, the second region of the siphon seal is filled with said liquid. The additional air duct can be designed as a hollow cylinder with any type of cross section. Particularly preferably, the additional air duct is designed as a hollow cylinder with a round, triangular, n-angled or rectangular cross section.

The additional air duct preferably has an air duct wall along the contour of the siphon seal, wherein the air duct wall has an inlet for air to enter the additional air duct and an outlet for air to exit from the additional air duct, in particular during spin-drying. The outlet of the additional air duct is spaced further from the siphon seal bottom than the inlet of the additional air duct. In particular, the inlet is disposed below the outlet relative to the orientation of the siphon seal. The inlet is preferably located in the first region and the outlet in the second region, wherein the inlet is exposed when a negative pressure is built up in the washing liquid container as a result of the liquid level falling in the first region. The outlet in the second area should be arranged high so that the outlet is exposed here even if the liquid is being displaced to such an extent in the second area that the inlet of the additional air duct is exposed. Pressure equalization can be achieved and no further movement of liquid from the first region to the second region can occur.

Preferably, the air duct wall of the additional air duct and the circumferential wall of the siphon seal are dimensioned such that, during the spin-drying, a liquid inventory remains in the siphon seal, which closes the siphon seal in a gas-tight manner after the spin-drying. During the spin-drying, the liquid inventory is displaced into a second region of the siphon seal, wherein a water column is built up in the second region, which is significantly larger than the water column in the first region and/or in the additional air duct. The negative pressure generated in the laundry drum during the spin-drying process therefore causes the liquid in the siphon seal to be displaced into the second region, whereby the additional air duct or the inlet thereof is at least partially exposed, so that air can flow into the laundry drum via the additional air duct.

The second region between the air duct wall and the peripheral wall of the siphon seal preferably forms a water reservoir in which the liquid is displaced during the spin-drying process. In the spin drying, the liquid is therefore displaced into the water reservoir, wherein the liquid forms a water column in the water reservoir, which preferably extends along the length, in particular the entire length, of the water reservoir. In this way, on the one hand, an additional air duct is provided by the air duct wall during the spin-drying process, in which an air flow can flow into the interior of the laundry drum. On the other hand, a water reservoir is formed in particular in the second region, which water reservoir is not occupied by the additional air duct and into which liquid is displaced during the spin-drying process. The water reservoir is capable of receiving a majority of the liquid. After the spin-drying process is completed, the liquid can flow back from the water reservoir, i.e. the second region, into the first region and into the region of the additional air duct, so that the siphon seal is closed again.

Preferably, the water reservoir has a volume for receiving the liquid, such that the additional air duct is exposed from at least part of the liquid, wherein the volume in particular receives the liquid substantially completely. Preferably, the volume of the water reservoir is sufficient to receive enough liquid to completely close the siphon seal again upon a pressure drop. It is conceivable that the liquid can be received substantially completely by the volume of the water reservoir as soon as a negative pressure is formed in the laundry drum during the spin-drying operation. It is also conceivable that the volume of the water reservoir is dimensioned such that it is possible to receive as much liquid through the volume as far as the additional air duct is exposed, but that part of the liquid remains in the bottom region of the first region of the siphon seal.

Preferably, the air duct wall at the outlet partially merges into the wall of the flushing-in housing and partially ends at a distance from the wall of the flushing-in housing, and at the inlet partially merges into the wall of the siphon seal and/or partially ends at a distance from the bottom of the siphon seal. Thus, the inlet is spaced from the bottom of the siphon seal. This makes it possible for the liquid in the siphon seal to flow into the second region when a negative pressure is built up in the washing liquid container, i.e. when the washing liquid is being spun. If the siphon seal has a partition, for example, this partition can merge into the wall of the flush-in housing at one end and can terminate at the opposite end at a distance from the bottom of the siphon seal. The partition wall ends at a distance from the bottom of the siphon seal, which ensures that an air flow can be formed in the additional air duct during the spin-drying process.

The different embodiments of the siphon seal proposed for laundry care machines constitute a one-way valve by its function as described herein. This means that air can flow into the laundry drum during the spin-drying process, whereas air cannot flow out of the laundry care machine during the drying process.

Detailed Description

Preferred novel embodiments are set forth below in conjunction with fig. 1, 3 through 6. Figure 2 shows a siphon seal according to the prior art.

Fig. 1 shows a laundry care machine 10 according to the prior art in a schematic view, having a wash-in housing 12 for introducing detergent. The laundry care machine 10 according to fig. 1 is shown with the most important functional components, which according to current practice are arranged in a housing, which is not shown at present, and which are connected to a control device, which is likewise not shown at present, in order to be controlled according to a predefined program.

The laundry care machine 10 comprises a washing liquid container 16 for receiving washing liquid for a washing process. In the washing liquid container 16, a laundry drum 28 is arranged for receiving the laundry 4. Water inlet lines 5 to 10 are used to flow water or wash liquor to the wash liquor container 16. A water inlet line 5 is connected to the water supply network and includes a controllable water inlet valve 6. The water inlet line 5 leads into a flush-in housing 7, in which an extractable flush-in housing 12 is located for introducing laundry care agents, such as detergents and/or softeners. Water mixed with the laundry care agent (here referred to as washing liquid or rinsing liquid) is passed from the rinsing housing 12 and the rinsing housing 7 through the rinsing liquid channel 9 into the rinsing liquid container 16. The washing liquid channel 9 comprises a siphon seal 18 which serves as an odor barrier between the washing liquid container 16 and the environment of the laundry care machine 10, in particular during washing processes which are operated at relatively high temperatures. The drain line comprises a washing liquor outflow line 11 connected to a washing liquor container 16, a washing liquor pump 12 and a riser line 13, which leads out of the laundry care machine 10 and is connected to the waste water system, and is provided for discharging washing liquor or rinsing liquor and primarily any waste water, in particular waste water after a washing process. The details of the connection of the washing liquid outflow line 11, which are known per se, such as the drain valve, are not shown. The laundry care machine 10 is equipped with the components mentioned so far for carrying out a known washing process for washing the laundry 4, a detailed description of which is superfluous here.

In order to be able to carry out a drying process for drying the laundry 4 with the aid of the laundry care machine 10, in particular a laundry care machine designed as a washer/dryer, the laundry care machine 10 is equipped with a drying tunnel. Which extends from an inlet 14 on the washing liquid container 16 up to an outlet 19 on the washing liquid container 16 and comprises between them drying air guiding means 15 for guiding drying air in a substantially closed circulation circuit containing the washing liquid container 16. In the drying air guide 15, in particular, a condenser 23, a blower 17 and a heater 21 are arranged. The circulating drying air is heated by means of the heater 21 and passes from the heater 21 through the outlet 19 into the washing liquid container 16 in order to absorb moisture from the laundry 4 there. Thereafter, the moisture-laden drying air passes through the inlet 14 to the condenser 23, where it is cooled so that the moisture condenses out in liquid form. The condensate thus produced is returned to the washing liquid container 16 and is discharged therefrom via the drain line. The drying air free of moisture is passed further by the drying air guide to the blower 17, which drives the drying air in the drying air circuit and further to the heater 21, where it is reheated in order to pass into the liquor container 16 again and to the laundry 4.

The condenser 23 is shown as a condenser 23 for cooling air and the heater 21 as an electric heater 21, as actually corresponds to a preferred configuration of the washer-dryer or the laundry care machine 10. However, also preferred is a configuration of the washer-dryer or laundry care machine 10 in which the condenser 23 and the heater 21 are components of a heat pump, wherein the condenser constitutes a heat sink and the heater constitutes a heat source.

Fig. 2 shows an enlarged view of the rinsing housing with the siphon seal 18 of the laundry care machine 10 according to the prior art. Fig. 2 shows that siphon seal 18 is divided by dividing wall 30 into a first region 32 and a second region 34. During the spin-drying process, the siphon seal 18, which is known from the prior art, presses water from the siphon seal 18 into the washing liquid container by means of the negative pressure which is formed in the washing liquid container, after which the air flow 26 enters the drum interior of the laundry drum 28 via the siphon seal 18. Here, the residual water in the siphon seal 18 is greatly reduced. Thus, during the drying process, hot, moist air can escape via the flush-in housing 12.

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

Fig. 3a, b show parts of a laundry care machine 10 in cross section with a siphon seal 18 according to the invention. It is proposed that the siphon seal 18 has an additional air channel 44 with a separating wall 30 and an air channel wall 46. Fig. 3a shows the proposed siphon seal 18 in a stationary state, i.e. in a state in which no spin-drying process is carried out. The water 42 in the siphon seal 18 is thus distributed into the first region 32, the additional air channel 44 and the second region 34, wherein the first region 32 is assigned to the flushing-in housing 12 and the second region is assigned to the additional air channel 24 of the washing drum 28. In this state, the proposed siphon seal 18 is closed according to fig. 3 a. In particular, in this state, the ambient pressure P _u Not significantly greater than the pressure P inside the drum _i 。

Fig. 3b shows the siphon seal 18 according to fig. 3a in an open state. The open state relates to a state in which the spinning process is performed. During the spin-drying process, the pressure P inside the drum _i Is significantly less than the ambient pressure P _u . This causes the water 42 in the siphon seal 18 to be displaced primarily into the second region 34 of the siphon seal 18, which is separated by the additional air passage 44 of the siphon seal 18. Only a small portion of the water 42 remains in the first region and in a partial region of the additional air duct 44. As can be seen from fig. 3b, the additional air duct 44 of the siphon seal 18 is exposed during the spin-drying process, so that the air flow 26 can be conducted from the first region 32 into the interior of the laundry drum 28 via the additional air duct 44 of the siphon seal towards the additional air duct 24 of the drum and cause a pressure equalization.

As can be gathered from fig. 3a and 3b, the additional air duct 44 of the siphon seal 18 has, in addition to the partition wall 30, an air duct wall 46. The dividing wall 30 extends into a wall 48 that is punched into the housing 12. Conversely, the air duct wall has an exposed end above and below, respectively, and merges into the partition wall 30 at the side. The inlet 50 is located at the lower end and the outlet 52 is located at the upper end. The inlet 50 of the additional air channel 44 of the siphon seal 18 is spaced from the bottom 54 of the siphon seal 18. The outlet 52 of the additional air channel 44 of the siphon seal 18 is spaced from the wall 48 of the flush-through housing 12. The partition wall 30 and the airway wall 46 each have a length and extend offset relative to each other such that the partition wall 30 and the airway wall 46 have different distances from the bottom 54 of the siphon seal. According to fig. 3a, 3b, the distance between the partition wall 30 and the bottom 54 is greater than the distance between the air duct wall 46 and the bottom 54. It is thereby achieved that during the spin-drying process, i.e. in the open state, water 42 can be conducted from the first region 32 and the additional air duct 44 into the second region 34. During the spin-drying process, the water column 56 formed in the second region 34 is significantly higher than the water column 58 formed in the first region 32 and in the partial region of the additional air duct 44. After the spin-drying process is completed, the water 42 can flow back from the second zone 34 into the first zone 32 and the additional air duct 44 again. This process would correspond to the transition from the open state according to fig. 3b into the closed state according to fig. 3 a.

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

According to fig. 4a, b, the siphon seal 18 is constructed with an additional air duct 44, which is arranged between the first region 32 and the second region 34 as a connection between the first and

second regions

32, 34. In the closed state (fig. 4a), the

water columns

58, 56 in the two

regions

32, 34 are formed at the same height, and the water 42 covers the inlet of the additional air duct 44, so that it does not allow air to pass through. In the open state (fig. 4b), the water column 56 formed in the second region 34 is larger or higher than the water column 58 formed in the first region 32. As a result, the water 42 is displaced from the additional air duct 44, so that the air flow 26 can flow through said additional air duct into the laundry drum 28. As shown in fig. 4a, b, the additional air duct 44 here extends between the two sides of the U-shaped tube forming the siphon seal 18, rather than directly in the siphon seal.

According to fig. 5a, b, the siphon seal 18 is formed with an additional air duct 44, which is formed in the siphon seal 18. In this embodiment, an additional air duct 44 is arranged in the transition from the first region 32 to the second region 34. As shown in fig. 5a, 5b, the additional air duct 44 has a shape following the contour 60 of the siphon seal. The additional air duct 44 has a duct wall 46. In the open state (fig. 5b), the water column 56 formed in the second region 34 is larger than the water column 58 formed in the first region 32. The water 42 thus flows down from the additional air duct 44, so that the air flow 26 can flow through said additional air duct into the laundry drum 28.

Fig. 6 schematically shows the flow of step S1 before the spin-drying course, step S2 during the spin-drying course, and step S3 after the spin-drying course. Prior to the spin-drying process according to step S1, the siphon seal 18 of the laundry care machine 10 is in the closed state (see fig. 3a, 4a and 5 a). This means that the water 42 is arranged not only in the first region 32, in the additional air duct 44 but also in the second region 34. The

water columns

56 and 58 extend in particular to a uniform level in this region, i.e. the

water columns

56 and 58 are of the same size.

In step S2, during the spin-drying process, a negative pressure P is generated inside the drum of the laundry drum 28 of the laundry care machine 10 _i This negative pressure causes the siphon water 42 to be expelled from the first region 32 and the additional air channel 44 into the second region 34. Step S2 thus corresponds to a transition from the closed state according to fig. 3a, 4a and 5a to the open state according to fig. 3b, 4b and 5 b. In this transition, the additional air duct 44 is exposed, so that the air flow 26 can flow via the first region 32 and the additional air duct 44 to the air duct 24 of the laundry drum 28 and a pressure equalization can be achieved. In this state, the water column 58 formed in the first region 32 is smaller than the water column 56 formed in the second region 34.

After the spin-drying process is completed, the water 42 can flow back from the second area 34 into the first area 32 and a partial area of the additional air duct 44. Step S3 thus transitions to the closed state according to fig. 3b,4b and 5b, corresponding to the open state according to fig. 3a, 4a and 5 a.

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