Description

Laundry care device with a fluid coupling

The present invention relates to a laundry care device with a fluid coupling. Conventional laundry care appliances may include a removable storage container for holding liquid such as e.g. Liquid Wäschepflegesubstanzen or water to absorb. The removable reservoir can be fluidly connected, inter alia, with a metering device. The metering device can be inserted into a storage container of the laundry care device and is designed to supply the received liquid to the laundry care device during a washing process. To ensure the operation of the metering device, the timely recognition of a low level of liquid in the removable reservoir is important. If the user of the household appliance is promptly pointed to the low level of liquid in the removable reservoir through the laundry care device, he can refill liquid in the removable reservoir. This avoids that the liquid in the removable reservoir is completely consumed, and the removable reservoir runs dry.

In EP 2 508 667 A1 a washing machine with a detergent container for receiving detergent is described, wherein the washing machine is designed to automatically supply the detergent to a tub of the washing machine.

It is the object underlying the invention to provide a laundry care device, in which an effective detection of a level of a liquid received in a removable reservoir of a metering device can be made possible.

This object is achieved by the subject matter having the features of the independent claim. Advantageous embodiments of the invention are the subject of the figures, the description and the dependent claims. According to one aspect of the invention, the object is achieved by a laundry care device having a removable storage container, the removable storage container having a container interior for receiving a liquid, wherein the removable storage container comprises a displaceable closing body for closing an opening in the removable reservoir, and with a fluid coupling for directing the liquid from the removable reservoir through the opening into a metering device of the laundry care device, wherein the fluid coupling is adapted to move the sliding closure body from a first position for closing the opening to a second position for releasing the opening, wherein the fluid coupling a first Electrode and a second electrode, wherein the first and second electrodes in the second position of the sliding closing body in contact with the container interior in contact in which a voltage can be applied to the first and second electrodes in the second position of the displaceable closing body, and wherein the laundry-care appliance has a controller which is electrically connected and formed with the first and second electrodes by means of a change in the voltage induced by the voltage Current flow to detect a level of liquid in the removable reservoir.

Thereby, the technical advantage is achieved that an effective fluidic connection between the removable reservoir and the metering device can be ensured by the fluid coupling, and that the level of the liquid in the removable reservoir can be determined by the control connected to the two electrodes effectively. In conventional laundry care appliances with an automatic dosing function, the laundry care appliance has a dosing device in which a liquid, such as, for example, a laundry care substance, is accommodated. The metering device is designed to supply the laundry care substance from a removable storage container, which is fluidically connected to the metering device, to the laundry care device. In this case, a liquid coupling is used in conventional laundry care equipment, which fluidly connects the removable reservoir with the metering device in order to allow feeding of the liquid from the removable reservoir into the metering device. In the laundry care device according to the invention, the fluid coupling not only enables an effective fluidic connection between the removable reservoir and the metering device, but also an effective electrical communication between the metering device and the removable reservoir. For this purpose there are two electrodes in the fluid coupling. When the fluid coupling is fluidly connected to the removable reservoir, the fluid coupling shifts the slidable closure body from the first position to close the opening to the second position to release the opening. Thus, the liquid can be supplied through the fluid coupling from the removable reservoir of the metering device. In the second position of the displaceable closing body, the two electrodes are in contact with the container interior, in particular with the liquid in the container interior. A voltage can be applied to the two electrodes in the second position of the displaceable closing body. When the two electrodes are in contact with liquid in the container interior, a current flow between the two electrodes is made possible by the voltage applied to the electrodes due to the electrically conductive property of the liquid. Since the two electrodes of the liquid coupling fluidically connected to the removable reservoir are arranged at a defined height to the removable reservoir, the controller can detect the occurrence of current flow through the liquid that the level of the liquid is disposed in the removable reservoir above the electrodes. On the other hand, in the event of a decrease in the flow of current through the liquid, the controller may also sense that the level of liquid in the removable reservoir falls below the level of the two electrodes, thereby detecting a sinking level of liquid in the removable reservoir.

Thus, the fluid coupling combines an effective fluidic connection between the removable reservoir and the metering device with an advantageous level detection of the liquid in the removable reservoir. Thereby, an additional electrical system for detecting the level of the liquid can be saved in the removable reservoir. In addition, may be on the introduction of live components to the removable Reservoir can be omitted, which no electrical isolation must be carried out and thereby costs can be saved.

A laundry care appliance is understood to mean a device which is used for laundry care, such as e.g. a washing machine or a tumble dryer. In particular, such a laundry care appliance is understood as a household laundry care appliance. So a laundry care device, which is used in the context of household management, and is treated with the laundry in normal household quantities.

In an advantageous embodiment of the laundry care device, the controller is designed to detect a vacancy of the liquid in the removable reservoir in the event of a drop in the current flow induced by the voltage.

Thereby, the technical advantage is achieved that can be detected by detecting the falling current flow through the controller, whether a vacancy of the liquid is present in the removable reservoir. When the liquid level in the removable reservoir is below one of the two electrodes in the fluid coupling, the electrode is no longer in contact with fluid but with air in the reservoir interior. Due to the electrically insulating properties of the air in the container interior, no current flow between the two electrodes can take place, and the current flow induced by the voltage between the two electrodes drops. This allows the controller to detect a vacancy of the liquid in the removable reservoir.

In a further advantageous embodiment of the laundry care appliance, the second electrode is arranged in the second position of the displaceable closing body at the opening in order to be in contact with the container interior in the second position of the displaceable closing body.

Thereby, the technical advantage is achieved that it is ensured by the positioning of the second electrode at the opening in the removable reservoir that when liquid is supplied from the removable reservoir through the opening and through the fluid coupling of the metering device, the second electrode with the liquid in Contact stands. As a result, the second electrode is at a with the Removable reservoir fluidly connected fluid coupling electrically conductively in contact with the liquid and the controller can detect a level of the liquid in the removable reservoir on the basis of a change in the current flow induced by the voltage. In a further advantageous embodiment of the laundry care device, the first electrode is arranged on an outer side or on an upper side of the fluid coupling in order to be in contact with the container interior in the second position of the displaceable closing body. Thereby, the technical advantage is achieved that is ensured by the positioning of the first electrode on the outside or on the upper side of the fluid coupling, that the first electrode in the second position of the sliding closure body is effectively in contact with the container interior. This makes it possible to ensure that an effective flow of current through the liquid is made possible by the first electrode arranged on the outside or on the top side of the fluid coupling with sufficient liquid level in the removable reservoir.

In a further advantageous embodiment of the laundry care device, the removable storage container has a further opening, wherein the further opening is closable by the displaceable closing body in the first position and releasable in the second position, and wherein the first electrode in the second position at the further opening is arranged. As a result, the technical advantage is achieved that it is ensured by the positioning of the first electrode to the other opening of the removable reservoir that the first electrode in the second position of the sliding closure body is effectively in contact with the container interior. By means of the first electrode disposed at the further opening, the controller can detect the level of the liquid in the removable reservoir by changing the current flow through the first and second electrodes. In a further advantageous embodiment of the laundry care appliance, the first electrode has a receiving region, which is accommodated in the liquid coupling, and the first electrode has a line section, wherein the line section is arranged in the second position of the displaceable closing body at the further opening.

This achieves the technical advantage that the first electrode can be fastened to the fluid coupling by means of the receiving region. In the positioning of the first electrode at the further opening, only the line section of the first electrode is arranged in the second position of the displaceable closing body at the further opening, whereby not the entire first electrode with the container interior, or the liquid in the container interior in contact stands.

In a further advantageous embodiment of the laundry care appliance, the fluid coupling has a fluid channel, wherein the fluid channel has a channel opening at an end facing the removable reservoir, the channel opening being fluidly in contact with the opening of the removable reservoir in the second position of the displaceable closing body Supply liquid from the removable reservoir through the opening, through the channel opening and through the liquid channel of the metering device of the laundry care device.

Thereby, the technical advantage is achieved that an efficient fluidic conduction of the liquid from the removable reservoir through the opening and through the channel opening in the liquid channel is made possible by the liquid channel of the fluid coupling, and the liquid can be effectively supplied through the liquid channel of the metering device of the laundry care device ,

In a further advantageous embodiment of the laundry care appliance, the second electrode is arranged at least in sections on the liquid channel in order to be in contact with liquid conducted through the liquid channel. This achieves the technical advantage that at least part of the second electrode is in contact with liquid due to the second electrode disposed at least in sections on the liquid channel when the liquid is passed through the liquid channel. As a result, the second electrode is in an effective electrically conductive contact with the liquid in the liquid channel.

In a further advantageous embodiment of the laundry care appliance, the displaceable closing body comprises a closing spring, wherein the closing spring in the second position can be pressed against the displaceable closing body with a spring force, and wherein the displaceable closing body can be displaced from the second position to the first position by relaxing the closing spring ,

As a result, the technical advantage is achieved that an effective closing of the container interior of the removable reservoir is made possible by the sliding closure body. When the fluid coupling is removed from the removable reservoir, the closing spring relaxes and displaces the sliding closure body from the second position to the first position. As a result, an effective closing of the removable reservoir is made possible when removing the fluid coupling. In a further advantageous embodiment of the laundry care device, the fluid coupling has a connection piece at an end remote from the removable reservoir, wherein the connection piece can be inserted into a receiving section of the metering device of the laundry care device in order to provide a fluid-tight fluidic connection between the fluid coupling and the metering device.

As a result, the technical advantage is achieved that an effective fluidic connection between the fluid coupling and the metering device is made possible by the connection piece.

In a further advantageous embodiment of the laundry care device, the displaceable closing body is in a cavity of the removable storage container arranged, wherein the fluid coupling is insertable into the cavity, and wherein the opening or the further opening is arranged in a cavity wall of the cavity.

Thereby, the technical advantage is achieved that an efficient fluidic connection of the fluid coupling is made possible with the removable reservoir through the cavity. The fluid coupling can be inserted into the cavity, whereby the displaceable closing body located in the cavity is displaced from the first position to the second position. Thereby, the closed in the first position of the sliding closure body opening in the cavity wall is released and liquid can be passed through the opening and through the inserted into the cavity fluid coupling.

In a further advantageous embodiment of the laundry care device, the fluid coupling can be introduced into the cavity through a cavity opening, in particular through a round cavity opening.

Thereby, the technical advantage is achieved that the fluid coupling through the cavity opening can be effectively inserted into the cavity. Thereby, an effective connection between the removable reservoir and the fluid coupling can be made to advantageously perform a supply of fluid through the fluid coupling.

In a further advantageous embodiment of the laundry care device, the fluid coupling has a sealing element or the displaceable closing body has a further sealing element for liquid-tight sealing of the cavity.

Thereby, the technical advantage is achieved that can be completed liquid-tight by the use of a sealing element on the sliding closure member or on the liquid coupling of the cavity. Thereby, leakage of liquid during the supply of liquid from the removable reservoir into the metering device can be prevented.

In a further advantageous embodiment of the laundry care device, the cavity is arranged on an underside of the removable storage container. Thereby, the technical advantage is achieved that it is ensured by the arrangement of the cavity on the underside of the removable reservoir that the fluid coupling is also introduced at the bottom of the removable reservoir into the cavity. By an effective level detection of the liquid can be carried out in the removable reservoir on the underside of the removable reservoir, whereby a particularly effective vacancy detection is made possible in the removable reservoir.

In a further advantageous embodiment of the laundry care appliance, the laundry care appliance has a display element for displaying a warning signal when the controller detects that the liquid level of the liquid in the removable storage tank falls below a predetermined liquid threshold value.

As a result, the technical advantage is achieved that the user can be informed by the display element on an insufficient amount of liquid in the removable reservoir. As a result, the user of the laundry care device can refill further liquid into the removable storage container or stop a laundry care program of the laundry care appliance, whereby dry running of the laundry care appliance can be prevented.

Further embodiments of the invention are illustrated in the drawings and will be described in more detail below.

Fig. 2 is a schematic representation of a fluid coupling; Fig. 3 is a schematic representation of an insertion process of a fluid coupling in a removable reservoir in a laundry care device; and Fig. 4 is a schematic representation of a fluid coupling used in a removable storage container in a laundry care device.

Fig. 1 shows a schematic view of a washing machine representative of a general laundry care device 100. The laundry care device 100 comprises a storage container 101, in the detergent or other liquid substances can be filled. The laundry care appliance 100 comprises a door 103 for loading the laundry care appliance 100 with laundry. As an alternative to the manual filling of Wäschepflegesubstanz into the storage container 101, a metering device, not shown in Fig. 1 in the storage container 101 can be used. The metering device may comprise a liquid, in particular a washing liquid, e.g. a laundry-care substance, automatically discharge into the storage container 101, whereby an automatic dosing process of laundry-care substance during a wash cycle of the laundry-care appliance can be made possible. Fig. 2 shows a schematic representation of a fluid coupling. The fluid coupling 105 is designed to fluidly connect a metering device (not shown in FIG. 2) to a removable reservoir (not shown in FIG. 2). For this purpose, the fluid coupling 105 has a coupling front side 107, which is in contact with the removable reservoir, and for this purpose has a connecting piece 109, wherein the connecting piece 109 can be inserted into a receiving portion, not shown in FIG. 2, of the metering device. Within the fluid coupling 105, a liquid channel 1 1 1 extends from the coupling end face 107 to the connecting piece 109 in order to ensure effective conduction of the liquid from the removable reservoir through the liquid channel 1 1 1 to the metering device.

In order to ensure a liquid-tight connection between the fluid coupling 105 and the removable reservoir, a sealing element 13, in particular a circumferential sealing ring, is arranged on the fluid coupling 105.

The fluid coupling 105 further has a first electrode 15 and a second electrode 117, which are arranged inside the fluid coupling 105 and can be connected to an electrical power source and a controller. The electric power source and the controller are not shown in FIG. 2.

Fig. 3 shows a schematic representation of an insertion process of a fluid coupling in a removable reservoir in a laundry care device. The removable reservoir 1 19 comprises a reservoir wall 121 and a reservoir bottom 123, which define a container interior 125. The removable reservoir 1 19 comprises a cavity 127 which is bounded by a cavity wall 129. The cavity wall 129 has an opening 131 and a further opening 133. Through the opening 131, liquid 135, in particular washing liquid, can flow out of the container interior 125 into the cavity 127. In order to avoid an uncontrolled escape of the liquid 135 from the cavity 127, a displaceable closing body 137 is disposed in the cavity 127. The displaceable closing body 137 comprises a further sealing element 139, in particular a circumferential sealing ring, in order to close off the displaceable closing body 137 in a fluid-tight manner with the cavity wall 129. The displaceable closing body 137 further comprises a closing spring 141, which can be pressed against the displaceable closing body 137 with a spring force. The cavity 127 is connected through a cavity opening 143, in particular through a circular cavity opening 143, to the outer region 145 of the removable reservoir 17.

Fig. 3 shows an insertion process of the fluid coupling 105 shown in Fig. 2 in the removable reservoir 1 19 in the laundry care device 100. The fluid coupling 105 is introduced with the coupling end 107 through the cavity opening 143 in the cavity 127 of the removable reservoir 1 19. The fluid coupling 105 has a sealing element 13, in particular a peripheral sealing ring, in order to ensure effective fluidic sealing between the fluid coupling 105 and the cavity 127 of the removable reservoir 1 19. The fluid coupling 105 has a fluid channel 1 1 1 to supply liquid 135 from the removable reservoir 1 19 through the liquid channel 1 1 1 of the metering device, not shown in FIG. Here, the fluid coupling 105 has a Connecting piece 109, wherein the connecting piece 109 is fluidly connected to the metering device.

As can be seen from Fig. 3, the fluid coupling 105 is inserted in an insertion 147 in the cavity 127 of the removable reservoir 1 19. The coupling end face 107 is in this case in contact with the displaceable closing body 137, which is in a first position. In the first position shown in Fig. 3, the closing spring 141 is relaxed, and the opening 131 and the further opening 133 are closed by the sliding closing body 137. By the closure of the first opening 131 and the further opening 133 by the displaceable closing body 137 an uncontrolled leakage of the liquid from the container interior 125 of the removable reservoir 1 19 is prevented.

Fig. 4 shows a schematic representation of the removable reservoir shown in Fig. 3 with an inserted fluid coupling in a laundry care device.

As shown in Fig. 4, the slidable closing body 137 has been moved by a movement of the fluid coupling 105 in the insertion direction 147 from the first position to the second position. In a fully inserted into the cavity 127 fluid coupling 105, the sliding closure body 137 is in the second position. In the second position, the opening 131 is not closed by the sliding closing body 137. As a result, liquid 135 can be supplied from the container interior 125 through the opening 131 and the liquid channel 1 1 1 of the liquid coupling 105 of the metering device not shown in FIG. 3. In the second position of the displaceable closing body 137, the further opening 133 is not completely closed by the displaceable closing body 137, but at least partially released. The first electrode 1 15 has a receiving region 149, which is accommodated in the fluid coupling 105, and has a line section 151, which is arranged in the second position of the displaceable closing body 137 at the further opening 133. Thus, the first electrode 1 15, in particular the Conduction portion 151 of the first electrode 1 15, with the liquid 135 in the container interior 125 in contact.

The second electrode 1 17 is at least partially disposed within the fluid coupling 105 on the liquid channel 1 1 1 and communicates with the guided through the opening 131 in the liquid channel 1 1 1 liquid 135 in contact.

As not shown in FIG. 4, the first and second electrodes 1 15, 17 are electrically connected to a voltage source, whereby a voltage can be applied to the first and second electrodes 15, 17. If liquid 135 is present at a sufficient level in the container interior 125, then the first and second electrodes 1 15, 17 are in contact with the liquid 135 and due to the electrically conductive properties of the liquid 135 there is a flow of current between the first electrode 1 15 and the second electrode 1 17. The first and the second electrode 1 15, 1 17 are further connected to a control, not shown in Fig. 4. The controller can detect the level of the liquid in the removable reservoir 1 19 based on the flow of the current passed through the liquid.

When the liquid 135 is discharged from the container interior 125 through the liquid channel 11 of the liquid coupling 105, the liquid level in the container interior 125 decreases, whereby the first electrode 15 arranged at the further opening 133 comes into contact with air. Due to the electrically non-conductive properties of the air, which is in contact with the first electrode 1 15, the current flow between the first electrode 1 15 and the second electrode 1 17 is interrupted. In this case, the control connected to the first and second electrodes 1 15, 1 17 can detect a drop in the current flow between the first electrode 15 and the second electrode 17. As a result, the controller can detect a drop in the level of the liquid in the container interior 125 and point the user of the laundry care device 100 to a vacancy of the liquid 135 in the removable reservoir 1 19.

Thus, by the fluid coupling 105, a mechanical and hydraulic connection between the removable reservoir 1 19 and the metering device provided. In addition, an electrical connection between the removable reservoir 1 19 and the metering device can be provided by the first and second electrodes 1 15, 1 17 integrated in the fluid coupling 105. In this case, the liquid 135 located in the removable storage container 1 19 closes the electrical circuit between the first and second electrodes 15, 17. Thus, the accessibility of the liquid 135 and the level of the liquid 135 in the removable storage container 1 19 with a single Liquid coupling 105 can be realized. As a result, an additional electrical system for detecting the filling level of the liquid 135 in the removable storage container 1 19 can be saved. In addition, no live components must be attached to the removable reservoir 1 19. Furthermore, no electrical isolation must be ensured, which can reduce costs.

All features explained and shown in connection with individual embodiments of the invention may be provided in different combinations in the article according to the invention, in order to simultaneously realize their advantageous effects.

The scope of the present invention is given by the claims and is not limited by the features illustrated in the specification or shown in the drawings.
