Description

Device combination of household appliances, method for operating an extractor device and

A computer program product

The present invention relates to a device combination, a method for operating an extractor device of a device combination and a

A computer program product.

Several kitchen appliances are usually used in a kitchen, such as hobs and grills. It is also known in a kitchen as a kitchen appliance

Use the extractor hood. These kitchen appliances usually have to be operated by the user.

However, extractor hoods that use sensors are already known. DE 103 07 247 A1, for example, describes a device for extracting exhaust air from an electric heating device. Here, an extractor hood is created with which exhaust air from an electric cooker can be extracted. In addition to a blower, the extractor hood has sensors, which can be gas sensors, for example, and are designed for detecting and evaluating gaseous media or substances in gaseous media. Depending on the pollution of the exhaust air or the concentration of odor-disrupting substances in the haze, the fan can only be switched on or its performance can be increased.

A disadvantage of these extractor hoods is that turning on the

Extractor hood only takes place at a late point in time when vapors and vapors have already formed and other ambient conditions cannot be taken into account.

It is therefore an object of the present invention to provide a solution by means of which reliable evacuation of vapors and vapors can take place during automatic operation of extractor devices with a simple structure. The invention is based on the knowledge that this object can be achieved by at least activating and deactivating and selecting the relevant extractor device on the basis of status information of a hob.

According to a first aspect, the object is therefore achieved by a combination of appliances comprising household appliances, at least one cooking appliance and at least one

Extractor hood device.

For example, two extractor devices in the form of fans can be integrated in an extractor hood. Alternatively, the extractor device can be a device that sucks off vapors and vapors in the level of the cooking appliance or slightly downward, offset to this level. These extractor hoods are also referred to as trough ventilation or downdraft. These fume extraction devices also preferably each have a fan and a suction opening. According to the invention, the device combination comprises at least two extractor hood devices. The

Extractor hoods are separate from the at least one cooking appliance

not necessary with each other.

According to one embodiment, a processing unit is provided on the extractor device (s) of the appliance combination. The

Processing unit can, for example, represent a control board or be provided on it. However, the processing unit of the extractor hood device is preferably only designed to execute received control signals. The algorithm by means of which the extractor hood device is controlled, however, is preferably stored in another processing unit.

According to one embodiment, the processing unit in which the algorithm is stored can be provided on a cooking appliance of the combination of appliances. Here, too, the processing unit can, for example, represent a control board or be provided on it.

Alternatively or additionally, the processing unit in which the algorithm is stored can also be provided on a mobile terminal of a communication network. This can be, for example, a cell phone or a computer, such as a tablet. In this embodiment, the

Processing unit represent an application that can also be called an app and is installed on the mobile device. Alternatively or additionally, the processing unit in which the algorithm is stored can also be provided on a separate communication device. This

Communication device can be provided exclusively for communication with the household appliances of the device combination and can also have one or more communication modules in addition to the processing unit.

A processing unit is preferably provided in each of the household appliances, but the algorithm for controlling at least one extractor hood device is stored in only one processing unit on the basis of the operating state of a cooking appliance. Programs or

Circuits can be stored in order to process received control signals.

According to a preferred embodiment, the device combination comprises at least one sensor, which at least at times interacts with the processing unit in which the

Algorithm is stored, is connected. The connection of the sensor to the algorithm is preferably a wireless connection and is used to transmit

Sensor signals to the processing unit. In the processing unit, the sensor signals can be taken into account when executing the algorithm and thereby the control of the at least one extractor device can be improved.

According to a preferred embodiment, the sensor is an air quality sensor. This type of sensor can ensure that the fume extractor device is not only activated, but also an appropriate fan level is set on the fume extractor device depending on the sensor signal of the air quality sensor, in order to be able to guarantee an acceptable air quality.

A hob or grill can be used as a cooking device in the device combination. The hob can be an induction hob, for example

Gas hob or a ceramic hob. The grill can be, for example, a teppan yaki grill. If several cooking devices are provided in the device combination, these are preferably different from one another. The extractor device in the device combination can be a fan

Extractor hood or a hob fan. With an extractor hood, several extractor devices, that is to say several fans, can be integrated in one hood. For example, separate fans for different cooking zones can be provided in the extractor hood. The downdraft fan is also known as downdraft and has a suction opening through which air is drawn downwards. The suction opening of the bowl fan is preferably adjacent to at least one cooking device of the device combination in the plane of the cooking device.

According to one embodiment, a cooking appliance and an extractor hood with several extractor devices are included in the appliance combination. According to an alternative embodiment, there are two or more cooking appliances and two

Extractor hoods each with an extractor device included. Another device combination comprises a cooking device and two extractor devices in the form of trough fans which are laterally adjacent to the cooking device. Another

Device combination includes two cooking devices and at least three

Extractor hoods in the form of trough fans. In this case, two extractor hoods are arranged adjacent to each cooking appliance and one

Extractor hood device is located between the two cooking appliances. However, it is also within the scope of the invention that other combinations of cooking appliances and

Extractor hoods are included in the device combination. In particular, the number of cooking appliances and extractor hood devices can deviate from the numbers mentioned. In any case, however, each cooking appliance is preferably at least one extractor hood device and particularly preferably at least two

Extractor hoods assigned. An extractor hood device is referred to as being assigned so that it can suck in at least part of the vapors and vapors produced by cooking on the corresponding cooking appliance.

According to a further aspect, the present invention relates to a method for operating at least one extractor device of an inventive

Device combination. The method is characterized in that an operating state of at least one of the at least one cooking appliance is detected and at least one extractor device is activated on the basis of this operating state. On the one hand, the activation and / or

In addition, the operating state of the cooking device, which is detected, preferably also includes the power level of at least part of the cooking device, for example a cooking zone. By the operating state of at least one

Cooking appliance is detected, the control of at least one

Extractor hood device can be made selectively according to the current conditions.

For example, when the cooking appliance is switched on, the extractor device can be automatically brought into a fully automatic operating mode. If the setting of the power in at least one cooking area, for example a cooking zone, is recorded as a further operating state of the cooking appliance, then the

Extractor hood device can be brought into an operating mode in which the fan level is set to a predetermined value.

By triggering the extractor device on the basis of the detected operating state of the cooking device, the extractor device can be set according to the prevailing or expected conditions.

According to the invention, the control of the extractor device can include the selection of the extractor device. Since according to the invention at least two

Operating state of a cooking appliance, for example, the extractor device adjacent to this cooking appliance can be selected and controlled. In addition, the activation preferably comprises the activation and / or deactivation of at least one extractor hood device. The activation of the extractor device can be the switching on of the extractor device. The deactivation can be the switching off of the extractor device. In addition, controlling the

Range hood device setting an operating mode. The operating mode can be a fully automatic mode, for example. Here, the

Extractor hood device activated so that manual input by the user is no longer necessary. Alternatively, the operating mode can also include setting a fan level on the extractor device. Finally, calling up a program, for example post-ventilation, can also set a

Display operating mode. According to one embodiment, at least one sensor signal is recorded and the

The extractor device is also activated on the basis of this sensor signal. The sensor signal is therefore in addition to the recognized operating state of the cooking device in the algorithm for controlling at least one

Extractor hood device used. The sensor signal is particularly preferably used to select the setting of an operating mode of the extractor device. By, for example, the fan level depending on the sensor signal

Air quality sensor is set, a reliable setting of a desired air quality can be guaranteed.

According to a preferred embodiment, the operating state of the

Cooking device that is detected, the position and preferably also the power level of a cooking zone of the cooking device. In cooking appliances such as hobs, several cooking zones are usually provided, on each of which food can be heated in a cooking vessel. If the method according to the invention detects that a cooking zone, which is located, for example, in the left area of the cooking appliance, points to one

Power level has been set, the detection of this operating state can be used to select a suitable extractor device. In particular, for example, a trough ventilation adjacent to the left side of the cooking appliance can be controlled.

According to one embodiment, in the method according to the invention, the number, type and position of the cooking devices, the number, type and position of the extractor devices and

where applicable, the number and position of the cooking zones of each cooking appliance

Advantages and features that have been described with regard to the device combination according to the invention also apply, where applicable, to the method according to the invention and the computer program product and vice versa.

The present invention will now be explained again with reference to the accompanying drawings. Show it:

Figure 1 is a schematic block diagram of a first embodiment of the device combination according to the invention; and

Figure 2 is a schematic block diagram of a second embodiment of the device combination according to the invention.

In Figure 1, a first embodiment of a device combination 1 according to the invention is shown schematically in a block diagram. The device combination 1 in this embodiment comprises three extractor devices 12, 13, 14, and two cooking devices, namely a hob 10 and a grill 11, which is a Tappan-Yaki grill. The extractor devices 12, 13, 14 represent trough fans, which are also known as downdrafts io

be designated. The hob 10 has four cooking zones 100, 101, 102, 103 in the embodiment shown. The extractor devices 12, 13, 14 are arranged laterally adjacent to the cooktop 10 and the grill 11, so that the middle extractor device 13 lies between the cooktop 10 and the grill 11.

Each of the devices 10, 11, 12, 13, 14 of the device combination 1 has one

Communication module 20, 21, 22. In addition, each of the devices 10, 11, 12, 13, 14 has a processing unit 23, 24, 25. The processing units 23, 24, 25 can be control boards of the respective device and can in particular represent printed cirucit boards (PCB). The communication modules 20, 21, 22 are connected to the respective processing unit 23, 24, 25 of the respective device 10, 11, 12, 13, 14 or integrated therein.

In the embodiment shown, a separate communication device 2 is provided in addition to the devices 10, 11, 12, 13, 14 of the device combination 1. The communication device 2 has a communication module 26 and one

Processing unit 27. The communication module 26 is connected to the

Processing unit 27 connected or integrated in this.

In addition, a sensor 3 is shown, which is preferably an air quality sensor. The sensor 3 can be integrated in one of the devices of the device combination 1 or can be attached separately to the device combination 1 in the room. It is also possible for more than one sensor 3 to be provided. The sensor 3 is designed such that it can transmit sensor signals to the processing unit 27 of the communication device 2.

In the embodiment shown, the algorithm for executing the method of operating at least one of the extractor devices 12, 13, 14 is executed in the processing unit 27 of the communication device 2. The algorithm can be stored in the processing unit 27 or in a storage unit (not shown) connected to it.

Before using the algorithm for the first time, information about the individual devices 10, 11, 12, 13, 14 of the device combination 1 must be stored in the processing unit 27 of the communication unit 2. In particular, the type and number of devices 10, 11, 12, 13, 14, their relative position to one another and the number of cooking zones 100, 101, 102, 103 of the hob 10 and their positions in the hob 10 are stored in the processing unit 27. This can be done via a user interface (not shown). In addition to this information, preferably

Information on the communication modules 20, 21, 22 of the respective devices 10, 1 1,

12, 13, 14 deposited. This information can, for example, address the

Communication modules in a communication network, for example a WLAN (wireless local area network).

The algorithm can be executed with this information.

If, for example, the cooking zone 103 of the cooktop 10 is activated, this can be done by the processing unit 27 by means of corresponding signals which are transmitted via the

Communication modules 21 and 26 are received, recognized. According to the algorithm and the stored information, the extractor device 13 is determined as the extractor device that is closest to the activated cooking zone 103. The extractor device 13 is therefore activated. Activation can do that

Turn on the extractor device 13 and operate with a predetermined fan level. If the sensor 3 detects that the air quality does not yet correspond to the values stored, the processing unit 27 can transmit a further control signal to the fume extractor 13, which increases the fan level of the fume extractor 13.

If, on the other hand, it is recognized that, for example, the grill 11 has been activated, the extractor devices 13 and 14 which are adjacent to the latter can be activated. With these, too, it can be determined after activation by processing the sensor signals whether the fan level needs to be increased. The fan stage of the extractor devices 13 and 14 can be increased again via control signals which are generated by the processing unit 27 on the basis of the stored algorithm

Communication device 2 were generated.

The communication between the communication modules 20, 21, 22 of the devices of the device combination 1 and the communication module 26 of the communication device 2 is, for example, wireless communication that can take place, for example, via WLAN.

The communication device 2 can also be referred to as a communication box and is particularly useful in configurations with greater complexity, such as the combination of two cooking appliances 10, 11 and three shown in the first embodiment

Extractor hoods 12, 13, 14 advantageous. The communication box can be integrated in one of the devices 10, 11, 12, 13, 14, for example in one of the cooking devices 10, 11, or be configured separately from these. Before starting up for the first time, the user preferably sets up the communication box. The communication box is informed which types of devices 10, 11, 12, 13, 14 are connected and how their positions are in the configuration. All devices 10, 11, 12, 13, 14 then communicate via the communication device 2, that is to say via the communication box.

It is the performance of each cooking device 10, 1 1 or the cooking zones 100, 101, 102, 103 contained and the feedback of the air quality sensor 3 when the

Extractor hood device (s) 12, 13, 14 taken into account.

FIG. 2 shows a second embodiment of the invention

Device combination 1 shown.

In this embodiment, the appliance combination 1 consists of a cooktop 10 with four cooking zones 100, 101, 102, 103 and two extractor hood devices 12, 13, which represent bowl fans and are arranged laterally adjacent to the cooktop 10. In addition, a sensor 3 is also provided in this embodiment. The hob 10 has a processing unit 24 and a communication module 21. The

Communication module 21 can be integrated in the processing unit 24 or connected to it. The extractor devices 12, 13 each have one

Processing unit 23 and a communication module 20. Here, too, the communication module 20 can be integrated in the processing unit 24 or connected to it.

In the second embodiment, the algorithm for operating at least one extractor device 12, 13 is preferably in the processing unit 24 of the

Hob 10 deposited. The algorithm can be on a control board, for example in be stored in a microprocessor. The algorithm specifies, for example, that when the activation of one or both cooking zones 101, 103 arranged on the right is recognized, the right extractor device 13 is activated. When the activation of one or both cooking zones 100, 102 arranged on the left is recognized, the left one

Extractor hood device 12 is controlled. The hob 10 with its cooking zones 100, 101, 102, 103 is treated as a master and the extractor devices 12, 13 as slaves.

In this embodiment, the communication modules 20, 21 can communicate, for example, via a local area network, such as WLAN. An application can be integrated in the WLAN network.

If it is recognized in the second embodiment that a cooking zone 100, 101, 102, 103 or a plurality of cooking zones 100, 101, 102, 103 are activated, the

Algorithm, which is stored in the processing unit 24 of the cooktop 10, selects one or both extractor devices 12, 13 and transmits a corresponding control signal to the extractor device (s) 12, 13.

For processing the control signals at the processing unit 20 of the

Extractor hood devices 12, 13, the software in the processing unit 20 can be updated or supplemented with corresponding processing logic.

In the second embodiment, a four-zone hob 10 is thus combined with two laterally arranged extractor devices 12, 13, which can also be referred to as downdraft. Each extractor device 12, 13 has its own fan, so that they can be operated separately from one another. If the user only uses one of the cooking zones 100, 101, 102, 103, for example on the left side, only the extractor device 12 which is arranged to the left of the hob 10 is operated. The extractor devices 12, 13 are thus automatically operated by the number of cooking zones 100, 101, 102, 103 that are switched on

Power and preferably the information from the air quality sensor 3. The information from the air quality sensor 3 is preferably used here only for setting a fan level but not for activating the extractor devices 12, 13. Furthermore, the appliance combination according to the invention can also combine, for example, a four-zone induction or gas cooking appliance with an extractor hood with at least two extractor devices. Here, the extractor hood, in particular an island hood or wall-mounted extractor hood, in which fans are provided as an extractor device. The width of the extractor hood is freely selectable. The extractor hood devices of the extractor hood preferably always remain in the fully automatic mode. When the user switches on the cooking device, in particular the induction device, at least one of the fans which is activated by the

Induction device is controlled, started automatically. The extractor hood can be completely controlled by the algorithm. This algorithm takes into account not only how many cooking zones are activated and the power with which each of these cooking zones is operated and in which position the cooking zones are, but also information from the air quality sensor. The more cooking zones are activated, the greater the output or the increased amount of vapors, lead to an increase in the flow rate. When the user finishes cooking and turns off the cooking zones, the fan or fans will automatically slow down and stop automatically. In this configuration of the appliance combination, in which only one hob and one extractor hood with two

Extractor hoods are used, the algorithm can be added, for example, on a control card in one of the devices. The devices can then communicate with one another via a communication module that is provided on the device for communication with programs or apps that can be installed on a mobile device. In this case, the cooking appliances in the algorithm are treated as masters and the extractor hoods as slaves.

The present invention has a number of advantages. While at

conventional extractor hoods with sensors, the user the

The extractor device must be manually set to an automatic mode in order to ensure that the fan can be activated on the basis of the sensor signals, the automatic mode setting can be carried out in the present invention

The extractor device is controlled by an algorithm in which the operating state of a cooking appliance is taken into account. The extractor device is preferably controlled by the cooking appliance. The extractor hood device in the device combination according to the invention can thus also be referred to as a fully automatic device. The extractor device can optionally be set once by the user in the fully automatic mode or the extractor device is delivered in the fully automatic mode. The cooking devices and the extractor devices are connected to one another in such a way that the cooking device or devices are able to control the extractor devices.

In addition, extractor devices can be used in the present invention, each having its own fan. Each fan is preferably driven by a brushless DC motor and can have an input of 0 to 10 volts. As a result, the fans can be managed and controlled by an electronic card, in particular a printed circuit board (PCB). Furthermore, in the present invention, one or more sensors can be integrated into the

Devices are integrated so that they can communicate with each other or at least with a central controller.

The user can now concentrate on the cooking process. The ventilation and especially the suction of vapors and vapors is handled automatically by the devices and no longer by the user.

Thanks to the present invention, the extractor devices become smart devices that are completely controlled by the cooking devices depending on their use by the user.
