Description

Laundry drying system

Technical Field

The present invention relates to a laundry drying system, in particular a system for drying laundry items without a laundry treatment device or for monitoring the drying of laundry items without a laundry treatment device.

Background

After the washing process, the damp laundry items are usually dried in a laundry treatment device, such as a laundry dryer, or in the free air inside or outside the building on a laundry hanging device. The free-air drying may last for one or more hours, in particular depending on the ambient conditions, and the user must monitor the drying process himself, in order to hang the dried items of laundry after the drying has been completed or to retrieve the items of laundry to be dried into the house in good time, for example before the start of a rain fall.

Disclosure of Invention

The object of the present invention is to provide a laundry drying system without a laundry treatment device, which has improved comfort for the user.

This object is achieved by a laundry drying system having the features of claim 1. Particularly advantageous embodiments and further developments of the invention are the subject matter of the dependent claims.

The laundry drying system according to the invention has at least one laundry gripper with a holding device for mounting the laundry gripper on the laundry hanging device and a clamping device for clamping the laundry items to the laundry gripper, wherein the laundry gripper is further provided with a first sensor unit for detecting the humidity of the laundry items clamped to the laundry gripper; and has an evaluation system for evaluating the sensor signal of the first sensor unit of the at least one laundry clamp and an output system for outputting information as a function of the evaluation result determined by the evaluation system.

The laundry drying system according to the invention provides for monitoring the drying process of the laundry items on the laundry hanging device, so that the user does not have to bother with the monitoring himself and thus provides better comfort for the user. By using intelligent laundry racks which can be constructed substantially similarly to conventional sensorless laundry racks, the laundry drying system according to the invention has a simple construction and can be used easily and conveniently by the user, since the user does not have to install additional monitoring devices on the laundry hanging device.

The laundry clamp, its holding means and its clamping means are not limited to any particular structure. Within the scope of the invention, any washing-article clamp configuration can in principle be used as a basis for the smart washing-article clamp. The base body of the laundry clamp is preferably made of plastic or wood. Of course, the smart laundry rack of the system according to the invention can also be used on a laundry hanging device, in addition to any conventional laundry rack which is only used for hanging laundry items. That is to say that it is sufficient for substantially only a part of the items to be washed to be suspended on the laundry hanging device by means of the smart laundry gripper.

The first sensor unit includes one or more humidity sensors for detecting humidity of the laundry items. The humidity sensors are not limited to any particular measurement technique, and they need only directly detect the humidity of the laundry items clamped on the same laundry clamp on which the humidity sensor is arranged. The moisture sensor can be arranged, in particular according to the measurement technique, inside the laundry rack, on the outside of the laundry rack or connected to the laundry rack, preferably in the region of the clamping device and thus of the clamped laundry.

The output system outputs information to the user, preferably optically and/or acoustically, and/or to another device in the form of digital data. The information output by the output system corresponding to the evaluation result is, for example, the evaluation result itself, a modified or supplemented evaluation result, an evaluation result matched to the respective user, etc.

In one embodiment of the invention, the system also has a central processing unit. In this case, the evaluation system preferably has a central evaluation device which is arranged in or on the central processor and is designed to evaluate the sensor signal of the first sensor unit of the at least one laundry gripper; the output system preferably has a central output device which is arranged in or on the central processing unit or is connected to the central processing unit; and the system further comprises a communication system for data transmission between the at least one laundry clip and the central processor. The central processor is, for example, a mobile terminal device (e.g., a smart phone, a tablet computer, etc.), a personal computer, a central control device of a smart home system, or a main wash clamp. The communication system preferably comprises a communication device in or on the laundry clamp and another communication device in or on the central processor. The communication system or its communication means are preferably designed as radio units for wireless data transmission. The laundry clamp preferably communicates with a local control device in/on the laundry clamp or directly with the first sensor unit. The use of a central processor is particularly advantageous for a laundry drying system with a plurality of intelligent laundry racks in order to evaluate the sensor signals of all the laundry racks centrally and to output the evaluation results centrally.

In one embodiment of the invention, the evaluation system has a local control and evaluation device connected to the first sensor unit, which is arranged in or on the laundry clamp and is designed to evaluate the sensor signal of the first sensor unit of the laundry clamp, and a communication system for data transmission between the local control device of the laundry clamp and the output system and/or the central processor. In this embodiment, the smart laundry rack therefore comprises an internal evaluation device in addition to the first sensor unit. In this way, the evaluation results may be sent directly to an output device (e.g., smartphone, display, speaker, etc.). If the system has a central processor as described above, the evaluation result can be sent directly to an output device in the center of the central processor and/or to an evaluation device in the center of the central processor for further evaluation. The communication system preferably comprises a communication device in or on the laundry clamp and another communication device in or on the output device or the central processor. The communication system or the communication devices thereof are preferably designed as radio units for wireless data transmission.

In a further embodiment of the invention, the laundry clamp also has a second sensor unit for detecting an environmental condition. In this case, the evaluation system is preferably designed to evaluate the sensor signals of the first sensor unit and of the second sensor unit of the at least one laundry gripper. The evaluation is preferably carried out in this case according to design variants by a central evaluation device of the central processing unit and/or a local control and evaluation device located in/on the laundry rack. Since the environmental conditions of the laundry hanging device influence the drying process, the evaluation results can be improved by also taking into account the environmental conditions. The second sensor unit preferably comprises one or more sensors for detecting air temperature, air humidity, light (or brightness or solar radiation), wind power, air pressure and/or rain.

In one embodiment of the invention, the clamping device of the laundry clamp has a first clamping arm and a second clamping arm between which the laundry can be clamped, and the first sensor unit of the laundry clamp has at least one first electrode mounted on or connected to the first clamping arm and at least one second electrode mounted on or connected to the second clamping arm, and the resistance and the capacitance between the at least one first electrode and the at least one second electrode are detected. Since the water or moisture in the items to be washed influences the electrical resistance and the electrical capacitance over a part of the items to be washed, the humidity of the items to be washed can be detected in a simple manner. Preferably, as large a spacing as possible is provided between the two electrode positions on the items to be washed, since this enables a higher accuracy of the measurement results. It may also be preferred to provide a plurality of first and second electrodes, since this also enables a higher accuracy of the measurement results.

In one embodiment of the invention, the laundry rack also has at least one solar cell for supplying power to electrical system components (e.g. first sensor unit, second sensor unit, control device, communication device, etc.) in the laundry rack. The electrical energy generated by the solar cell is preferably stored in a capacitor or battery in the laundry clamp.

The evaluation system is preferably designed to determine one or more information from the sensor signals of the first sensor unit or from the sensor signals of the first sensor unit and the second sensor unit, the information being selected from the group consisting of the current humidity of the laundry items, the current dryness of the laundry items, the remaining drying duration of the laundry items and the end time of drying of the laundry items.

If the laundry drying system comprises a plurality of laundry racks with a first sensor unit or with a first sensor unit and a second sensor unit, the evaluation system is preferably designed to determine, on the basis of the sensor signals of the sensor units of the plurality of laundry racks, one or more pieces of information selected from the group consisting of the current humidity of the laundry items, the current average humidity of the laundry items, the location-specific current average humidity of the laundry items, the current dryness of the laundry items, the current average dryness of the laundry items, the location-specific current average dryness of the laundry items, the remaining drying duration of the laundry items, the drying end time of the laundry items, the location-specific remaining drying duration of the laundry items and the location-specific drying end time of the laundry items. In the case of a plurality of laundry racks, for example, a minimum and/or a maximum remaining drying duration can be determined. In the case of a plurality of laundry racks, for example, the earliest and/or latest drying end time can be determined. The term "location-specific" in this context denotes a location-dependent determination when a plurality of laundry clips are positioned at different drying locations or drying zones (e.g. different laundry hanging means under different environmental/weather conditions).

In one embodiment of the invention, the system also has a communication system for querying weather information from the internet. According to design variants, the communication system can have a communication device on the central processor and/or a communication device on the laundry clamp. The evaluation system is in this case preferably designed to evaluate the sensor signals of the first sensor unit or the sensor signals of the first sensor unit and the second sensor unit in conjunction with weather information in the internet.

In a design variant with a second sensor unit and/or an internet connection, the evaluation system is preferably also designed to determine information relating to weather forecasts and/or current weather conditions. For example, a prompt may be output to the user that it is soon time to rain or a wet night is coming.

If the central processor is the central control device of the smart home system or a device connected to the smart home system and at least one laundry treatment device (for example a washing machine) is connected to the smart home system, the at least one laundry treatment device can be operated by the assistance of the laundry drying system according to the invention of the smart home system as a function of the evaluation result determined by the evaluation system. Thus, for example, when the remaining drying duration determined for the items of laundry on the laundry hanging device is shorter than the duration of the washing process, the washing process of the washing machine can be started, so that the next item of laundry to be washed only has to be hung when the previous item of laundry has been dried and can be removed.

In a further embodiment of the invention, the system also has an input device, by means of which a user can start and end the operation of the system. The input device preferably has a switching element arranged on the laundry clamp and/or a central input device arranged in or on the central processing unit or connected to the central processing unit. Preferably, a further or the same input device for inputting additional information (for example, the type of laundry) by the user can also be provided, in order to take the additional information into account when evaluating the sensor signal and to further improve the quality of the evaluation result.

The subject matter of the invention also comprises an intelligent laundry rack for the above-described laundry drying system according to the invention.

Finally, the subject of the invention is also a smart home system with the above-described laundry drying system of the invention.

fig. 2 shows a laundry drying system according to a second embodiment of the invention; and

fig. 3 shows a laundry drying system according to a third embodiment of the present invention.

Detailed Description

With reference to fig. 1, a first exemplary embodiment of a laundry drying system according to the invention is now described in detail.

The laundry drying system of fig. 1 basically comprises at least one intelligent laundry clamp 10 and a central processor 40. The laundry gripper 10 is designed to suspend the laundry items 12 to be dried on the laundry suspension device and to monitor the drying process together with the central processor 40.

In this exemplary embodiment, the laundry gripper 10 has a base body 14, for example made of plastic, which is formed by a first clamping strip 15a and a second clamping strip 15b, which are connected to one another by a hinge connection 16. In the lower region of the laundry gripper 10, a clamping device 17 for clamping the laundry items 12 is provided, which has a first clamping arm 18a formed by a lower section of the first clamping strip 15a and a second clamping arm 18b formed by a lower section of the second clamping strip 15 b. The first and

second clamping bars

18a, 18b receive laundry items to be dried therebetween. In order to increase the clamping action, the first clamping arm 18a has a projecting first clamping jaw 19a on its side facing the second clamping arm 18b and the second clamping arm 18b has a projecting second clamping jaw 19b on its side facing the first clamping arm 18a, so that the laundry items 12 are held between the two clamping

jaws

19a, 19 b.

In the upper region of the laundry gripper 10, the two

gripper bars

15a, 15b have a first handle 20a or a second handle 20 b. Between the two

handles

20a, 20b, a pressure spring 21 is arranged, which presses the two

handles

20a, 20b apart from one another and thus pretensions the two clamping

arms

18a, 18a toward one another in order to clamp the laundry items 12. In order to release the clamped laundry items 12 or to insert the laundry items 12 to be dried into the clamping device 17, the user can press the two

handles

20a, 20b against the force of the pressure spring 21 towards each other and thus move the two clamping

arms

18a, 18b away from each other. In order to mount the laundry gripper 10 on a laundry hanging device, for example in the form of a laundry rope, a recess is provided as a retaining device 22 between the two clamping

strips

15a, 15b in the region below the hinge connection 16.

The construction of the laundry clip 10 of fig. 1 is merely exemplary. The smart laundry clamp 10 of the laundry drying system according to the invention can also have any other base body, clamping device, handle, spring element and/or retaining device.

As shown in fig. 1, the laundry gripper 10 is also provided with a first sensor unit 24 in the region of the clamping device 17 and thus in the region of the clamped laundry items 12. The first sensor unit 24 is designed to detect the moisture content of the items of laundry clamped in the clamping device 17 of the laundry clamp 10. In this exemplary embodiment, the first sensor unit 24 has a moisture sensor with a first electrode 25a in the first clamping jaw 19a of the clamping device 17 and a second electrode 25b in the second clamping jaw 19b of the clamping device 17, which are connected to the control device 26. The water in the items of laundry 12 between the two

gripping arms

18a, 18b affects the resistance and capacitance of the items of laundry, so that the humidity of the items of laundry can be determined by detecting the resistance or capacitance between the two

electrodes

25a, 25 b. The described embodiment of the first sensor unit 24 is merely exemplary. The smart laundry clamp 10 of the system according to the invention can also be equipped with any other humidity sensor with any measuring technology.

The control device 26 in the laundry clamp 10 is connected to a communication device (e.g. a radio unit) 27, via which the sensor signal of the first sensor unit 24 can be transmitted, preferably wirelessly, to an evaluation system. The control device 26 is also connected to an energy store (e.g. capacitor, accumulator, battery) 28 for supplying power to the control device 26, the communication device 27 and the first sensor unit 24. Optionally, at least one solar cell 29 is mounted on the laundry gripper 10, for example on the

handle

20a, 20b, and is connected to an energy store 28 in order to charge the latter.

As shown in fig. 1, the smart laundry clip 10 optionally further comprises a second sensor unit 30 for detecting environmental conditions. The second sensor unit 30 has one or more sensors 31 to 34, for example in the region of the

handles

20a, 20 b. In the embodiment of fig. 1, the second sensor unit 30 includes a temperature sensor 31 for detecting the temperature of air, an air humidity sensor 32, a wind sensor 33, and a light sensor 34 for detecting the brightness or solar radiation. The second sensor unit 30 is likewise connected to the control device 26 and is likewise supplied with power from the energy store 28. The sensor signals of the second sensor unit 30 are likewise transmitted via the communication device 27.

The central processor 40 is, for example, a mobile terminal (such as a smart phone or a tablet computer), a personal computer, or a central control device of a smart home system. If the laundry drying system has a plurality of smart laundry racks 10, the central processor may also be provided by the main laundry rack.

As shown in fig. 1, the central processor 40 has a central evaluation device 41 for evaluating the sensor signals of the first sensor unit 24 and, if present, also of the second sensor unit 30, a communication device 42, a central output device 43, for example in the form of a display, and a central input device 44. The transmission of the sensor signals of the

sensor units

24, 30 to the central evaluation device 41 is effected by data transmission from the communication device 27 in/on the laundry clamp 10 to the communication device 42 of the central processor 40.

The user can start or end the operation of the laundry drying system via the central input device 44. Corresponding operating signals are transmitted from the communication device 42 of the central processor 40 to the communication device 27 of the laundry clamp 10 in order to switch the control device 26 and the

sensor units

24, 30 on and off. Optionally, the central input device 44 can also be designed such that the user can also input additional information via the central input device, for example the type of laundry of the laundry items 12 to be dried, in order to be able to take these additional information into account when evaluating the sensor signal by the central evaluation device 41, in order to thus further improve the quality/accuracy of the evaluation result.

The central evaluation device 40 of the central processing unit 40 can determine, for example, the current humidity of the clamped laundry items 12, the current dryness of the clamped laundry items 12, the remaining drying duration of the laundry items 12 and/or the drying end time of the laundry items 12 on the basis of the received sensor signals of the first sensor unit 24 and, if present, of the second sensor unit 30. Basically, the sensor signal of the first sensor unit 24 is sufficient to determine the humidity or dryness. In order to determine the remaining drying duration or the drying end time, the sensor signal of the second sensor unit 30 is preferably also taught. Optionally, other weather information from the internet 46 can also be taken into account in the evaluation, which can also be called up, for example, via the communication means 42 of the central processor 40. Information corresponding to the evaluation result is then displayed for the user on the display 43.

The central evaluation device 40 can also determine information relating to weather forecasts or current weather conditions if a second sensor unit 30 is provided and/or if a connection to the internet 46 exists. The user may then be output, for example, via the output device 43, a warning prompt: it is immediately anticipated that it will be raining or that a wet night will start on the horse, so that the user should better take the laundry to be dried back into the house from the outside.

The laundry drying system preferably comprises a plurality of intelligent laundry clamps. In this case, the humidity of a plurality of laundry items 12 on different laundry racks 10 can be detected, and the environmental conditions at a plurality of locations of different laundry racks 10 can be detected. Based on the respective sensor signals of the plurality of laundry racks 10, the central evaluation device 41 can, on the one hand, improve the quality of the evaluation result by comparing the sensor signals and, on the other hand, determine further evaluation results, such as, for example, the current average humidity of the plurality of laundry items, the location-specific current average humidity of the laundry items in different locations, the current average dryness of the plurality of laundry items, the location-specific current average dryness of the laundry items in different locations, the minimum and/or maximum remaining drying duration of the laundry items, the earliest and/or latest drying end time of the laundry items, the location-specific remaining drying duration of the laundry items and the location-specific drying end time of the laundry items.

With reference to fig. 2, a second exemplary embodiment of a laundry drying system according to the invention is now described in detail. Here, the same or corresponding components are denoted by the same reference numerals as in the first embodiment.

The laundry drying system of fig. 2 comprises essentially at least one smart laundry gripper 10 and an output device 47.

The basic structure of the laundry gripper 10 (components 14 to 22) corresponds to that of the first exemplary embodiment. Furthermore, the laundry gripper 10 is provided with a first sensor unit 24 and optionally also a second sensor unit 30, as in the first exemplary embodiment.

In contrast to the first exemplary embodiment, the laundry gripper 10 of fig. 2 does not comprise a simple local control device 26, but rather a local control and evaluation device 35, which local control and evaluation device 35 also evaluates the sensor signals of the

sensor units

24, 30. The evaluation result is then transmitted by the communication device 27 to the communication device 48 of the output device 47, which then outputs the corresponding information directly to the user. The output device 47 is, for example, a mobile terminal device (e.g., a smartphone or a tablet computer) or a display. As shown in fig. 2, the local control and evaluation device 35 of the laundry gripper 10 can also optionally query weather data from the internet 46 via the communication device 27 and take these into account together when evaluating the sensor signals.

As shown in fig. 2, a user-actuatable switching element 36 can also be provided on the laundry clamp 10 in order to switch the smart laundry clamp 10 on or off.

In other respects, the structure and operation of the laundry drying system of fig. 2 corresponds to the structure and operation of the first exemplary embodiment of fig. 1.

The features of the first and second embodiments may also be combined with each other. For example, the smart wash clamp 10 may communicate with either the central processor 40 or the output device 47 directly. Furthermore, the laundry gripper 10 of the first exemplary embodiment can also comprise a local control and evaluation device 35 instead of the local control device 26, the local control and evaluation device 35 evaluating the sensor signal of the first sensor unit 24 and, if a second sensor unit 30 is present, also the sensor signal of the second sensor unit 30, so that the communication device 27 then transmits the evaluation result, instead of the sensor signal, to the central processor 40, wherein the evaluation result is then output directly from the central output device 43 in the central processor or is further evaluated by the central evaluation device 31, for example, taking into account further information or parameters.

With reference to fig. 3, a third exemplary embodiment of a laundry drying system according to the invention is now explained in detail. Here, the same or corresponding components are denoted by the same reference numerals as in the first embodiment.

Fig. 3 shows an exemplary laundry hanging device 50 with a plurality of laundry cords, on which a total of four smart laundry clamps 10 are mounted. The smart wash clamp 10 may alternatively correspond to the smart wash clamp of the first embodiment of fig. 1 or the smart wash clamp of the second embodiment of fig. 2. In addition to the four smart laundry racks 10, further laundry items 12 can be suspended from the laundry hanging device 50 by means of standard conventional laundry racks, i.e. purely mechanical laundry racks for hanging laundry items only.

The four smart wash clamps 10 each communicate with a central control 40 of a smart home system 40, which corresponds to, for example, the central control 40 of fig. 1.

Furthermore, when the laundry treatment device 52, such as a washing machine, is connected to the smart home system, the central control device 40 may preferably operate the laundry treatment device 52 according to the evaluation result determined by the central evaluation device 41 of the central control device 40. In this way, for example, a washing process of the washing machine 52 can be prevented until the determined remaining drying time of the items of laundry 12 on the laundry suspension device 50 is sufficiently shorter than the duration of the washing process, so that only when the previous items of laundry 12 have finished drying at the laundry suspension device 50 and can be removed, the next item of laundry 12 to be washed has to be removed from the washing machine 12 and suspended for drying.
