The DE 102 04 455 A1 discloses a dishwasher with a microphone. The dishwasher is set up to detect a defect on the basis of an evaluation of the sounds recorded with the microphone or to monitor and, if necessary, modify a rinse program sequence.

The object of the present invention is to provide a reliable household appliance.

The object of the invention is achieved by a household appliance, comprising at least one acoustic sensor for receiving a noise of the household appliance and a communication interface, wherein the household appliance is configured to evaluate output signals of the at least one acoustic sensor, which are associated with the noise of the household appliance to one to detect impending failure of at least one component of the household appliance, to operate the component in a gentler mode from the moment of the detected imminent defect, and to communicate via its communication interface a message about the imminent defect of the component to a communication device which Assigned to a customer service of the household appliance.

The household appliance according to the invention accordingly comprises the at least one acoustic sensor. In particular, a microphone is used as the acoustic sensor. With the at least one acoustic sensor noises of the household appliance, that is, noises generated by the household appliance during normal operation, recorded in order to monitor the household appliance, in particular at least one component of the household appliance. This is achieved by an evaluation of the output signals of the at least one acoustic sensor.

Preferably, the output signals of the at least one acoustic sensor are continuously evaluated or only when the component to be monitored is in operation.

For the evaluation, the household appliance according to the invention preferably comprises an electronic evaluation device. This preferably comprises a digital signal processor and is coupled to the at least one acoustic sensor. The electronic evaluation device is thus configured to evaluate the output signals of the at least one acoustic sensor to detect the impending failure of the at least one component of the household appliance, so that the household appliance from the time of the detected imminent defect to operate the component in the gentler operation and over the communication interface is able to transmit the message about the imminent defect of the component to the communication device.

The household appliance according to the invention may have a display device, wherein the household appliance may be configured to display information about the detected defect by means of the display device.

The component of the household appliance which is monitored by means of the output signals of the at least one acoustic sensor is e.g. a bearing with which a further component of the household appliance is rotatably mounted. The further component is e.g. rotated by an electric motor of the household appliance. Bearings may e.g. refuse. By means of the at least one acoustic sensor, it is then possible for the household appliance, in particular by means of its electronic evaluation device, to monitor the bearing on the basis of the recorded noises, to evaluate the output signals, in order preferably to recognize an imminent defect of the bearing as early as possible. If an impending failure of the bearing is detected, then preferably the further component rotating electric motor can be operated for the bearing gentler.

A gentle for the bearing operation can preferably be achieved by the electric motor with a lower maximum speed, with a lower maximum power, and / or with a, the electric motor and / or the camp gentler characteristic is operated.

The component of the household appliance, which is monitored by means of the output signals, may be an electric motor of the household appliance, which is provided to operate during operation of the household appliance, a further component of the household appliance.

A gentle for the electric motor operation can preferably be achieved by the electric motor with a lower maximum speed, with a lower maximum power, and / or with a, the electric motor gentler characteristic is operated.

The household appliance according to the invention is e.g. a laundry treatment machine having as a further component a rotatably mounted by means of the bearing laundry drum, which is rotatable by means of the electric motor. The laundry treating machine is e.g. a washing machine or a tumble dryer. It includes the means of the at least one bearing rotatably mounted laundry drum, which is rotated during operation by means of the electric motor. The laundry treating machine is thus configured to recognize, based on the evaluated output signals of the at least one acoustic sensor, an imminent defect of the bearing and / or the electric motor to then create the message and transmit and the electric motor in one for the camp and / or the electric motor to operate more gentle operation.

The household appliance according to the invention is e.g. a domestic dishwasher, which has as a further component a rotatably mounted by means of the bearing spray arm, which is rotatable by means of the electric motor, and / or having as a further component a circulation pump with the electric motor. The household dishwasher in particular comprises the at least one, by means of at least one bearing rotatably mounted spray arm, which is rotated during operation by means of the electric motor. The household dishwasher is thus adapted to recognize, based on the evaluated output signals of the at least one acoustic sensor, an imminent defect of the bearing and / or the electric motor for the spray arm, to then create the message and transmit and the electric motor in one for the camp and / or to operate the electric motor more gentle operation. The household dishwasher in particular comprises the circulating pump, which comprises an electric motor. The household dishwasher is thus set up to recognize an imminent defect of the circulating pump or its electric motor on the basis of the evaluated output signals of the at least one acoustic sensor, in order to then create the message and transmit it and the circulating pump or its electric motor into a more gentle operation operate.

The household appliance according to the invention is e.g. Domestic refrigerating appliance having a heat-insulated inner container with a coolable interior and a refrigerant circuit for cooling the coolable interior, which has as a further component a compressor comprising the electric motor. The household refrigerating appliance comprises the compressor and is thus set up, on the basis of the evaluated output signals of the at least one acoustic sensor, to recognize an imminent malfunction of the compressor or its electric motor, in order to then prepare and transmit the message and the compressor or its electric motor to operate a more gentle operation.

The household refrigerating appliance according to the invention or in general the domestic appliance according to the invention can also comprise as component at least one adjusting flap, at least one fan and / or at least one valve.

In today's household appliances, there is sometimes a tendency in development to reduce troublesome noises such as the running engine in a spin-washing machine. The same applies to the noise in a dishwasher (spray), refrigerator (compressor), fans in the oven, etc. These sounds are audible to humans and often disturbing.

Sometimes the operator of the household appliance can predict based on the noise of his household appliance, whether a component of the household appliance is already damaged or is about to fall out. This can e.g. Bearing noise of the motor shaft or the like. In each of these cases, the device is no longer ideal, consumes unnecessarily much energy, is annoying loud or is about to complete a total failure.

According to the invention, by means of the at least one acoustic sensor, e.g. evaluated by means of an implemented microphone and preferably by means of a signal processor, for example similar to the human ear, for example, acoustic signal characteristics. This is possible both in a human audible and non-audible frequency range (near ultrasound and infrasound).

Acoustic scenarios can be assigned in particular to functional impairments and disorders. For example, the ideal, i. quiet and energy-saving running of a washing machine on many factors, such as the loading of the laundry drum, water filling the laundry drum, motors and bearings, drive belts, correct installation of the machine.

Due to a relatively high sensitivity of an acoustic signal processing, the household appliance according to the invention can perceive and evaluate errors in the formation, long before the operator of the household appliance aware perceives them.

Thus, it is possible, by providing early information to the customer service, e.g. over the Internet or similar communication interfaces, e.g. to prevent greater damage. The customer service can thus, before the owner of the household appliance ever noticed anything about a claim, react early to a possible use or provide the operator with an improved service.

In addition, the household appliance automatically switches to a kind of gentle (emergency) mode in the event of an imminent defect. That is, for example, the home appliance is no longer operating in the maximum modes, e.g. highest speed for the laundry drum in a washing machine or the compressor motor in a household refrigerator.

If this damage occurs at the end of the life cycle of a household appliance, its life is extended by a certain time using this gentle mode of operation.

Due to the household appliance according to the invention premature failures and defects can be counteracted early. An error evaluation and optimization of the systems according to personal and country-specific features (online or offline) can also be made possible.
