Description

Hand-held device for improved laundry treatment, system with such a hand-held device and method for its operation

The invention relates to a hand-held device comprising at least one spectrometer with at least one radiation source and at least one radiation detector, a microscope camera and a microcomputer, wherein the microcomputer has an interface for wireless data communication and a data memory. The invention also relates to a method for operating a hand-held device. The invention further relates to a system with such a hand-held device and a method for operating such a system.

At present, in general, the wear of individual items of laundry in households is not systematically recorded. For example, in laundries and / or rental clothing service providers, individual items of laundry are specifically marked or provided with bar code-like codes. The reading is usually done with manual effort, as a caption and / or coding, which is attached to a specific location of a piece of laundry, is not always directly detectable or readable.

An alternative may be, for example, RFID chips. These make it possible to transmit information about a single item of laundry over distances and without direct eye contact. Disadvantage of these chips, however, is that they must be attached to each individual piece of laundry. This is partly associated with high costs. In addition, the placement of individual laundry items with RFID chips can cause an unpleasant feeling of "surveillance" or "control". It would therefore be desirable to be able to improve the treatment of household laundry articles and to be able to easily grasp the effects of the treatment on the properties of laundry items.

In this embodiment, the laundry-care-relevant properties determined by the hand-held device 39 and the information obtained by the external user terminal 11 can then be stored in a data memory of the microcomputer 6 and / or in a data memory of the external user terminal 11 under a predetermined identifier K _x , for example Ki. Business saved and linked. For this purpose, both the microcomputer 6, and the external user terminal 1 1 have an interface for wireless data communication. In this way, a cataloging of existing in a user household laundry can be made possible.

FIG. 3 shows a non-limiting embodiment of a system according to the invention comprising a handset 39, an external user terminal 11 and a home appliance 13. In this embodiment, the handset 39 and the external user terminal 11 correspond to the embodiment of FIG Only the properties of the household appliance 13 with reference to the embodiment of the system according to the invention are described below.

The household appliance 13 is designed in this embodiment as a washing machine. The washing machine 13 has a housing 25, in which a tub 15 is arranged, in which a drum 16 for receiving laundry items 10 is rotatably mounted about an axis perpendicular to the plane axis. In the drum 16 two Wäschemitnehmer 14 are arranged.

In the embodiment shown here, a tub outlet line 30 is connected to a drain opening 31 in a bottom of the tub 15, which leads via a lint 29 to a suction side of a pump 27. To a pressure side of the pump 27, a drain line 24 is connected. The drain line 24 opens outside the housing 25, not shown here, in a domestic drainage or a floor drainage. A speed-controlled drive motor 26, which may be configured, for example, as a permanently excited, multi-strand synchronous motor with a MOSFET component and a power detector 28, is drivingly connected to the pump 27 and the drum 16.

FIG. 3 also shows an automated dosing unit 20 for treatment agent, which is connected to an induction bowl 22. About the Einspülschale 22 is the

Lye container 15 from a fresh water line 23 coming from water fed.

For this purpose, there is a check valve 21 in the fresh water line 23, of a

Control device 18 is driven according to a treatment program sequence.

The washing machine 13 also has in this embodiment a display 19, which is suitable for displaying information in the form of text, image and / or animation in black and white and / or color.

The spectrometer 35 is configured in this embodiment as an infrared spectrometer and has a corresponding radiation source 32, a radiation detector 33 and a microcomputer 34. In this embodiment, the radiation source 32 emits radiation in the range of 400 nm-1000 nm and / or 1000 nm-5000 nm. In this embodiment, the spectrometer is in one of the two Laundry pickup 14 integrated. In addition, a microscope camera 17 is integrated into the same laundry driver 14.

If, for example, a user places a piece of laundry 10 in the drum 16 of the washing machine 13, an image of the item of laundry 10 can be created by the microscope camera 17. In addition, the laundry item 10 can be acted upon by radiation from the radiation source 32 of the spectrometer 35. The radiation reflected by the laundry 10 may then be registered by the radiation detector 33 as a measurement signal. Both the image of the microscope camera 17, and the measurement signal can then be evaluated by the microcomputer 34. The evaluation takes place here with regard to the laundry care-relevant properties stored under the label K _x . From a comparison of the two data records, the laundry item 10 fed into the drum 16 can then be identified, for example, as K _{1 B} usiness. If the item of laundry 10 is identified, the laundry care-relevant properties and the information stored under the identifier Ki, Business can be transmitted to the control unit 18 of the washing machine 13. For this purpose, the control device 18 preferably has an interface for wireless data communication. On the basis of the transmitted laundry care-relevant properties and the information, a laundry treatment program can then be selected by the control device 18 and proposed to a user for execution via the display 19 and carried out after confirmation or be carried out directly.

If the washing machine 13 additionally has a photo camera 36, then a photograph of the laundry label of the laundry item 10 can also be created when it is inserted into the drum 16 and the laundry care-relevant properties obtained therefrom can additionally be used to identify the laundry item 10. For this purpose, the photo camera 16 is then preferably arranged in the region of a door opening of the washing machine 13. Reference handset
