Description

Home appliance security system and method for switching a household appliance

The subject matter relates to a home appliance backup system having a communication module for receiving switching signals and for transmitting control signals representing the switching signals via a home automation bus, and an actuator remote from the communication module for receiving the control signals. The subject matter further relates to a method for securing a household appliance.

The security of household appliances is an important one

Part of home security. In particular, in large electrical appliances, such as herds, which have an increased power consumption, it is important to ensure against overheating. Furthermore, it is necessary that the power supply to these devices can be safely shut off. On the one hand, this is necessary when

Repairs to the household appliances are necessary and on the other hand, however, if, for example, the household appliances are accidentally not shut down by the consumer and the consumer leaves his house. Even then, the operation of the large household appliance is critical to safety, as it can overheat over a longer period and it can cause fires in homes and houses.

Most devices are connected via plug and socket to the power grid. These devices can be easy are unplugged and are then no longer on

Energy distribution network of the house connected. This is different for some large appliances, such as herds. These are hardwired to the house distribution network and can only be accessed via a circuit breaker

Fuse box are turned off. Owing to

Installation instructions for large electrical appliances are not allowed to provide an intermediate plug between the fuse box and the large electrical appliance, which could allow a shutdown. If the electrical connection between the supply protection and the main household appliance is to be disconnected, it is necessary that the respective fuse be transferred in the fuse box. This is expensive and can lead to unwanted delays in case of danger.

For this reason, the object was the object to provide a home appliance security system available, which satisfies installation instructions and at the same time allows a comfortable securing a household appliance.

This object is achieved by a system according to claim 1 and a method according to claim 9.

It has been recognized that with the help of an actuator, at least one contactor associated with the household appliance can be switched. In this case, the shutdown of the

Household appliance or the separation from the electrical

Supply network directly to the fuse, namely the contactor and at the same time a control command can be triggered from a location away from the fuse box. This is sufficient for one, the installation rules, since

actually no intermediate switch between fuse box and household appliance is provided and on the other hand, the comfort is high because the switching signal can be triggered from a remote location. The contactor or the contactors secure the individual phases, preferably the phases LI, L2, L3 of the connecting line with the household appliance. At the phases is preferably a three-phase current with a voltage of 360 volts. With the help of the contactor, a safe separation of the phases of the

Supply network done. The contactor is usually in

Fuse box installed. The contactor has an input via which a switching signal can be fed from the actuator. This makes it possible to switch the contactor via an actuator which is galvanically separated from the phases. The actuator can be controlled by the communication module, which communicates with the actuator on one side and can receive switching signals on the other side. Thus, it is possible for a user to set the switching signals away from the contactor, and thus safely and

Installation instructions enough to turn off the home appliance. The communication module is free from

Switching functions, so that it does not need to be specially secured electrically. The communication module is used

merely for receiving the switching signals and for

Forwarding these as control signals, in particular via a home automation bus.

A particularly simple assembly is ensured by the fact that the actuator for mounting on a mounting rail,

especially a DIN rail, preferably a TS35

DIN rail, in particular in a distribution cabinet, is formed. The actuator can be in close proximity to the Contactor, preferably in the safety cabinet, to be installed. The switching output of the actuator can then be connected via a conductor bridge to the switching input of the contactor.

Preferably via a radio communication, but also via a wired communication, the actuator can communicate with the communication module. When installing the distribution cabinet, the installing electrician can place the actuator next to the contactor directly on the DIN rail

be attached.

Often, a defect of a household appliance is detected directly on this. In order to then quickly disconnect the household appliance from the electrical network, conventionally, the user would have to go to the distribution cabinet and move the respective shooter. Objectively, it is now possible that the

Communication module spatially directly to the

switching household appliance is arranged. For example, the user can press a button and thus the

Communication module transmit a switching signal. This switching signal is converted into a control signal, which leads to switching of the household appliance associated contactor.

Especially comfortable is one

Home appliance backup system when the communication module is a radio receiver. In this case can by a

Radio transmitter, such as a radio frequency radio transmitter or an infrared radio transmitter, a switching signal are issued by the user, which is received by the communication module and is converted into a control signal. Often the communication follows between the

Communication signal and the actuator a different protocol than the communication between, for example, a transmitter, which is used by the user, and the

Communication module. In this case, it is proposed that the communication module has a protocol converter. With the aid of the protocol converter, it is possible to convert switching signals received according to a first protocol into control signals sent in accordance with a second protocol. A switching signal, for example, an opening or

Close a button that is connected to the communication module. The corresponding control signal can then be considerably more complex, for example when this is a radio system, for example a radio-based

Home automation system, is transmitted. In this case, redundancy can be added to the control signal. It is also possible that the communication module monitors the reception of the control signal by the actuator and a

corresponding receipt acknowledgment expected.

According to an advantageous embodiment, as already indicated above, it is proposed that the communication module transmits the control signals by means of radio. For this purpose, for example, a communication can take place via a radio-based home automation bus. It only has to be ensured that the radio communication between the communication module and the actuator is not disturbed. According to an advantageous embodiment of the

Switching output of the actuator a low-voltage switching output. Thus, the actuator is subject to low installation requirements and is installable by a private user. One

Low voltage switching output is preferably a 12 volt or 24 volt switching output. With the help of such

Low-voltage switching output, it is possible to switch a contactor. In order to enable galvanic isolation between the switching output of the actuator and the control circuit of the actuator, it is proposed that the switching output is that of a relay. In this case, the actuator has a relay which controls the switching output. As a result, a galvanic decoupling of the actuator is ensured by the switching output. Furthermore, by the contactor another galvanic

Decoupling of the input of the contactor ensured by the phases to be switched. This significantly increases safety. According to an advantageous embodiment is

suggested that the contactor is a 3-phase contactor. The contactor preferably switches switching voltages between 200 and 400 volts, preferably between 230 and 360 volts. Such a contactor is suitable, for example, a

Switch high power electrical appliance. This can

For example, be an electric stove or an electric oven.

As already explained above, according to an advantageous embodiment, the contactor and the actuator in one

be arranged common distribution cabinet. This is

advantageous because then the cable bridge between the

Switching output of the actuator and the switching input of the contactor can be short and immediately by the electrician

can be attached, which installs the distribution cabinet. It is also possible for a home user to install the actuator in the distribution cabinet, especially this one

Hinged rail in the distribution cabinet and the Switching output of the actuator connects to the switching input of the contactor.

The contactor is preferably for switching a

Large electric appliance, in particular with a power consumption of more than 1 kW, preferably more than 2.5 kW or 3 kW,

educated. Such large electrical appliances are, for example, electric stoves and electric furnace. Secure communication between the communication module and the actuator is ensured, for example, even if the home automation bus has a central control unit. A remote control of the communication module and the actuator is for example possible if the central control unit with a wide area network,

preferably the Internet, is connected. About the

Wide area network, the central control unit thus via a communication protocol, such as TCP / IP, a

Receive switching signal. This switching signal can be triggered by any computer within the wide area network.

It is also possible for a user to use a

Mobile device transmits the switching signal via the wide area network to the central control unit. On the other hand, it is also possible that the central control unit on the one hand has a connection to the wide area network and on the other a local radio connection, such as a local wireless connection with a computer or phone builds. Thus, a user can send out the switching signal via his telephone either via the wide area network or via the local radio network and controls the central control unit by means of this switching signal then over the

Home automation the communication module or directly with corresponding control signals to the actuator.

According to an advantageous embodiment is

suggested that the switching signals from a

User remote, a timer, a

Motion detectors, a smoke detector and / or an alarm system are receivable. A user remote can do this

can be used so that the user settles a switching signal, without being spatially close to the communication module. With the help of a timer, for example, it is possible to separate a large electrical appliance according to time specifications from the network, for example, during vacation periods or at night.

With the help of a motion detector, it is possible, for example, to determine whether a person is spatially in the vicinity of the electrical appliance. Only in the case of physical proximity between the user and the large electrical appliance is it necessary for it to be electrically connected to the supply network. For this reason, the motion detector can be used to control the connection between the supply network and the electrical appliance via the contactor.

With the help of a smoke detector, it is possible, for example, to detect smoke in a room. If the smoke detector strikes, for example, as a precaution, the large electrical appliance can be disconnected from the distribution network by the smoke detector transmitting a switching signal to the communication module, which subsequently activates the actuator for switching the contactor. Also in case of alarm, by an alarm system

is triggered, as a precaution, the large electrical appliance can be disconnected from the mains.

As already explained, a method according to claim 9 is also claimed.

The aforementioned methods can also be called

Computer program or as on a storage medium

stored computer program can be realized. This can communication module side, actuator side and / or

On the server side a microprocessor to carry out the

respective process steps to be suitably programmed by a computer program.

The features of the methods and devices are freely combinable. In particular, features of the description and / or the dependent claims, even with complete or partial circumvention of features of the independent claims, alone or free

being inventive in their own right.

Subsequently, the object is based on a

Embodiment showing drawing explained in more detail. In the drawing show

Fig. 1 shows a system according to an advantageous

Ausführungsbei game;

Fig. 2 is a sectional view through a

DIN rail mounting of an actuator Fig. 1 shows a communication module 2 and an actuator 4. The actuator 4 is connected to a contactor 6. For this purpose, the actuator 4 has a switching output 8. A communication between the communication module 2 and the actuator 4 via a home automation 9 either wirelessly via a radio link 9a or wired via a cable 9b.

The actuator 4 and the contactor 6 are preferably in a common distribution cabinet, for example one

Safety cabinet mounted on a DIN rail 10.

A DIN rail 10 can be seen in Fig. 2. In Fig. 2 it is indicated that both the actuator 4 and the contactor 6 can be plugged onto the top hat rail 10. This considerably facilitates the mounting of both the actuator 4 and the contactor 6, since top hat rails 10 are generally present in all distribution cabinets and enable them to mechanically fix the devices arranged thereon.

Fig. 1 further shows an electric oven 12, which is connected via a line 13 3-phase electrically connected to the contactor 6. The line 13 has no adapter plug and is hardwired. Only a screw in the region of the line 13 is permitted. The contactor 6 secures the phases 20 LI, L2, L3.

The communication module 2 has a protocol converter 14, which can receive signals from a radio receiver 16 and convert these switching signals into control signals. For example, the user may send out a switching signal via a radio remote control which is received by the radio receiver 16. The radio receiver 16 directs this

Switching signal to the protocol converter 14 um, which converts it into a control signal. The control signal is then preferably via the radio link 9a according to a

Home automation bus protocol transmitted to the actuator 4. As soon as the actuator 4 receives a control signal, it converts this into a switching level of the switching output 8. The switching output 8 is connected to a switching input 18 of the contactor 6. Depending on the level of the switching signal on the

Switching output 8, the contactor 6 is opened or closed, so that the phases 20 of the electric stove 12 of the

Be disconnected or connected to this supply network.

The communication between the communication module 2 and the actuator 4 and the contactor 6 can be carried out independently of a central control device 22. The central

However, control device 22 can also over the

Home automation bus communicate via a radio link 34 with both the communication module 2 and the actuator 4 and query their states as well as their states

change.

The central control device 22 is on the one hand, as already mentioned, via the radio link 34 in a position with the actuator 4 and the communication module 2 according to a

Home automation bus protocol to communicate. On the other hand, the central control device 22 is connected to a router 30 which, on the one hand, establishes a connection to a wide area network 24 and, on the other hand, for example a local area network via a W-Lan connection 32 allows.

To the wide area network 24, which, for example, the

Internet is, on the one hand, a web server 26 and on the other hand, for example via a GSM or UMTS radio link 36, a mobile phone 28 may be connected. With the help of

For example, a mobile phone 28 may also disconnect the appliance 12 from the power supply. For this purpose, a connection to the web server 26 can first be established by means of the mobile telephone 28. An access authorization check can take place via the web server 26. Upon successful authentication, the web server 26 may connect between the mobile 28 and the

establish central controller 22 via the router 30. Subsequently, the user via the mobile phone 28th

Switching signals to the central control device 22nd

transmit to the corresponding switching levels at the

Lead switching 8 and thus the electric stove 12 on and off.

It is also possible that via the mobile phone 28, which is here representative of any access devices to the

Wide area network, such as laptops, tablet PCs, tablets, smart phones or the like is called, a direct connection via the wireless LAN 32 and the router 30 are made with the central controller 22. Even then, by means of the mobile phone 28, the switching output 8 of the actuator 4 can be influenced.

With the help of the actuator 4, it is possible to switch the contactor 6. This makes it possible to install instructions to satisfy and at the same time a control of a
