Abstract

A communications module for a household device includes a sensor device that is configured to be attached in the region of a device housing of the household device, a wireless data interface and a processor. The sensor device is configured to scan an emission signal, penetrating outwards through the device housing, of a component of the household device carrying out the operating process of the household device. The processor is configured to determine an operating state of the household device based on measurement values of the sensor device and to provide same by means of the data interface. In addition, the communications module can be used optionally in different types of household devices.

First claim

The invention claimed is:

1. A communication module for a household appliance, the communication module comprising:
a sensor device configured for attachment in a region of a housing of the household appliance;
said sensor device being configured to scan an emission signal, which passes through the housing to the outside, of a component of the household appliance carrying out an operating process of the household appliance;
a further sensor device for scanning a further emission signal of the household appliance;
a wireless data interface;
a processor configured to determine an operating state of the household appliance based on measured values of said sensor device and said further sensor device, and to output the operating state by way of said data interface; and
wherein the communication module is configured to be selectively used on different types of household appliances, the communication module being configured to shift the further sensor device of the communication module from a power-saving mode to an operating mode when the emission signal scanned by said sensor device indicates a change in the operating state of the household appliance.

2. The communication module according to claim 1 , wherein said processor is configured to determine a type of the household appliance on a basis of the measured values of said sensor device.

3. The communication module according to claim 2 , wherein predetermined emissions respectively are associated with a plurality of predetermined types of household appliances, and said processor is configured to compare measured values, which are scanned by way of said sensor device during operation of the household appliance, with predetermined emissions in order to determine on which type of household appliance the communication module is being used.

4. The communication module according to claim 1 , wherein said further sensor device is configured to scan a region on an exterior of the housing of the household appliance for a measurable variable which is connected to the operating process of the household appliance.

5. The communication module according to claim 1 , wherein said further sensor device comprises a VOC sensor.

6. The communication module according to claim 1 , wherein said processor is configured to provide a progress of a program of the household appliance with respect to an expected program end.

7. The communication module according to claim 1 , wherein the operating state comprises an energy consumption of the household appliance.

8. The communication module according to claim 1 , wherein said processor is configured to send a notification when a predetermined operating state of the household appliance is reached.

9. A system, comprising:
a communication module according to claim 1 ; and
a mobile device having a wireless data interface for receiving the operating state of the household appliance from said communication module, wherein said mobile device is configured to output a warning if said mobile device is removed from a predetermined region of the household appliance while the household appliance is in operation.

10. A method for determining an operating state of a household appliance, the method comprising the following steps:
using a sensor device of a communication module for scanning an emission signal that passes through an appliance housing to an exterior of a component of the household appliance carrying out an operating process of the household appliance;
using a further sensor device of the communication module for scanning a further emission signal of the household appliance;
shifting the further sensor device of the communication module from a power-saving mode to an operating mode when the emission signal scanned by the sensor device indicates a change in the operating state;
determining a type of the household appliance on a basis of measured values of the sensor devices;
determining the operating state of the household appliance on the basis of measured values of the sensor devices and the type determined in the determining step; and
outputting the operating state thus determined.
