DEVICE COMBINATION OF HOUSEHOLD APPLIANCES, METHOD FOR OPERATING A COUNTERTOP AND COMPUTER PROGRAM PRODUCT

Description

[0001] The present invention relates to a device combination, a method for operating a fume hood of a device combination and a computer program product.

[0002] A kitchen typically uses several appliances, such as cooktops and grills. It is also common to find a range hood in a kitchen. These appliances usually require user operation.

[0003] However, extractor hoods that use sensors are already known. For example, German patent DE 103 07 247 A1 describes a device for extracting the exhaust air from an electric heating appliance. This device is a range hood that can extract the exhaust air from an electric stove. In addition to a fan, the range hood has sensors, which can be, for example, gas sensors, designed to detect and evaluate gaseous media or substances in gaseous media. Depending on the level of pollution in the exhaust air or the concentration of odor-causing substances in the fumes, the fan can be switched on or its performance increased.

[0004] One disadvantage of these extractor hoods is that they are only switched on at a late stage, by which time fumes and vapors have already formed and other environmental conditions cannot be taken into account.

[0005] Furthermore, WO 2017 / 029135 A1 discloses a combination appliance comprising a cooktop with at least one cover plate and at least one heating element, and a range hood arranged below the cooktop, which includes at least one fan for extracting air from the space above the cooktop. The combination appliance is characterized by the fact that the cooktop has at least one opening located in the edge area of ​​the cooktop's cover plate, and that this opening serves as the intake opening for drawing air into the combination appliance.

[0006] EP 3 045 824 A1 describes a device for extracting exhaust air above a cooktop, comprising at least one exhaust air inlet, a fan, and an exhaust air outlet. A cooktop can be incorporated into the device.

[0007] EP 2 261 568 A1 discloses a kitchen appliance with one or more electrical and / or electromechanical devices, a user-facing front surface, and a side surface featuring a touch-sensitive control element. The control element allows operation of one or more electrical and / or electromechanical devices of the same kitchen appliance and / or of one or more other kitchen appliances. Communication with the other kitchen appliance(s) is wireless.

[0008] A combination of an induction hob with a range hood is known from DE 10 2012 210 844 A1.

[0009] The object of the present invention is to provide a solution by means of which reliable extraction of fumes and vapors can be achieved in the automatic operation of extractor hoods with a simple design.

[0010] The invention is based on the finding that this problem can be solved by at least activating and deactivating as well as selecting the relevant extractor hood device on the basis of state information from a cooktop.

[0011] According to a first aspect, the problem is therefore solved by a combination of household appliances comprising at least one cooking appliance and at least two extractor hoods, wherein the at least two extractor hoods and the at least one cooking appliance each have a communication module and a processing unit, and each of the extractor hoods is at least temporarily connected to at least one cooking appliance of the combination via at least two of the communication modules, and the combination has a processing unit, which can be the processing unit of the at least one cooking appliance and which is at least temporarily connected to at least one of the communication modules, and an algorithm is stored in the processing unit of the at least one cooking appliance by which at least one extractor hood of the combination can be controlled based on its operating state.namely, the activation and / or deactivation and / or power level of a cooking zone, at least one cooking appliance of the appliance combination, is controlled at least temporarily... Each of the extractor hoods is wirelessly connected at least temporarily to at least one cooking appliance of the appliance combination via at least one of the communication modules.

[0012] According to a second aspect of the invention, the problem is solved by a device combination of household appliances comprising at least one cooking appliance and at least two extractor hoods, as well as a mobile terminal of a communication network and / or a separate communication device, wherein the at least two extractor hoods and the at least one cooking appliance, as well as the mobile terminal and / or the separate communication device, each have a communication module and a processing unit, and each of the extractor hoods is at least temporarily connected to at least one cooking appliance of the device combination via at least two of the communication modules, and the device combination has a processing unit.which can be the processing unit of the mobile device and / or the separate communication device of the at least one cooking appliance and which is at least temporarily connected to at least one of the communication modules and which contains an algorithm in the processing unit of the mobile device and / or the separate communication device, by which at least one extractor hood of the appliance combination is controlled at least temporarily based on the operating state, namely activation and / or deactivation and / or a power level of a cooking zone, of at least one cooking appliance of the appliance combination, wherein the operating state of the cooking appliance includes the position and power level of a cooking zone of the cooking appliance, wherein each of the extractor hoods is at least temporarily wirelessly connected to at least one cooking appliance of the appliance combination via at least one of the communication modules.

[0013] The appliance combination comprises at least one cooking appliance and at least one extractor hood. The cooking appliance preferably has a cooking surface. The cooking appliance can be a hob or a grill. An extractor hood is defined as a device that includes a fan and preferably has at least one filter. For example, two extractor hoods in the form of fans can be integrated into a range hood. Alternatively, the extractor hood can be a device that draws fumes and vapors downwards in the plane of the cooking appliance or slightly above this plane. These extractor hoods are also known as downdraft ventilation systems. These extractor hoods also preferably each have a fan and an intake opening. According to the invention, the appliance combination comprises at least two extractor hoods.The extractor hoods are designed separately from the at least one cooking appliance. The extractor hoods and the at least one cooking appliance thus constitute self-contained household appliances. In particular, the extractor hoods preferably each have their own control unit. Furthermore, the extractor hoods may also have separate power connections. However, the extractor hoods and the at least one cooking appliance are preferably installed together.

[0014] The device combination includes at least one communication module. A communication module is a component that enables the transmission of control signals between devices. Communication via the communication module can be wired or wireless.

[0015] Each of the extractor hoods is connected, at least temporarily, to a cooking appliance in the appliance combination via at least one communication module. This connection serves, for example, to transmit control signals. However, other information, such as the status of an appliance in the appliance combination, can also be transmitted via this connection.

[0016] Furthermore, the device combination includes a processing unit. This processing unit is connected, at least temporarily, to at least one of the communication modules. The device combination may also include multiple processing units. The processing unit could, for example, be a microprocessor or an application on an electronic device. The processing unit may be integrated into the control unit of one of the devices in the device combination. The processing unit contains an algorithm that controls at least one extractor hood of the device combination, at least temporarily, based on the operating state of at least one cooking appliance in the device combination.

[0017] Control is achieved via the at least one communication module. In particular, control signals or status information from the cooking appliance can be transmitted from the cooking appliance to at least one of the extractor hoods via the at least one communication module. In this embodiment, the algorithm is preferably stored in the processing unit of one of the cooking appliances or in a processing unit of a separate communication device.

[0018] By controlling one or more extractor hoods based on the operating state of at least one cooking appliance, the extractor hood can be switched on even before fumes and vapors are produced, as in the invention. Furthermore, the communication between the appliances in the combination allows for a flexible design of the appliance combination.

[0019] According to the invention, each of the extractor hoods is wirelessly connected, at least temporarily, to at least one cooking appliance of the appliance combination via at least one of the communication modules. For this purpose, the communication module preferably includes appropriate communication means, such as antennas or adapters. The wireless communication between the appliances of the appliance combination further increases the flexibility in the design of the appliance combination. In particular, cabling between the individual appliances is not required.

[0020] According to one embodiment, a processing unit is provided on each of the extractor hood(s) of the device combination. The processing unit can, for example, be a control board or be integrated on one. Preferably, however, the processing unit of the extractor hood is designed only to execute received control signals. The algorithm by which the extractor hood is controlled, on the other hand, is preferably stored on a different processing unit.

[0021] According to one embodiment, the processing unit in which the algorithm is stored can be provided on a cooking appliance within the appliance combination. Here, too, the processing unit can, for example, be a control board or be located on one.

[0022] According to the invention, the processing unit in which the algorithm is stored can also be provided on a mobile device connected to a communication network. This could be, for example, a mobile phone or a computer, such as a tablet. In this embodiment, the processing unit can be an application, also known as an app, which is installed on the mobile device.

[0023] 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 exclusively intended for communication with the household appliances of the device combination and may also include one or more communication modules in addition to the processing unit.

[0024] Preferably, each household appliance contains a processing unit, but only one processing unit contains the algorithm for controlling at least one extractor fan based on the operating state of a cooking appliance. The other processing units may contain programs or circuits to process received control signals.

[0025] According to a preferred embodiment, the device combination comprises at least one sensor that is at least temporarily connected to the processing unit in which the algorithm is stored. The connection between the sensor and the algorithm is preferably wireless and serves to transmit sensor signals to the processing unit. In the processing unit, the sensor signals can be taken into account during the execution of the algorithm, thereby improving the control of the at least one extractor hood.

[0026] According to a preferred embodiment, the sensor is an air quality sensor. This type of sensor ensures that the extractor fan is not only activated, but also that an appropriate fan speed is set on the extractor fan depending on the sensor signal from the air quality sensor, in order to guarantee acceptable air quality.

[0027] The cooking appliance in the combination unit can be, for example, a cooktop or a grill. The cooktop could be, for example, an induction cooktop, a gas cooktop, or a ceramic cooktop. The grill could be, for example, a teppanyaki grill. If several cooking appliances are included in the combination unit, they should preferably be different from each other.

[0028] The extraction device in the appliance combination can be a range hood fan or a downdraft extractor. A range hood can integrate multiple extraction devices, meaning multiple fans, into a single unit. For example, separate fans can be provided for different cooking zones within the range hood. A downdraft extractor, also known as a cooktop extractor, has an intake opening through which air is drawn downwards. The intake opening of the downdraft extractor is preferably located adjacent to at least one cooking appliance in the appliance combination, at the same level as the cooking appliance.

[0029] According to one embodiment, the appliance combination includes a cooking appliance and a range hood with multiple extraction units. According to an alternative embodiment, it includes two or more cooking appliances and two range hoods, each with one extraction unit. Another appliance combination comprises a cooking appliance and two downdraft extractors located laterally adjacent to the cooking appliance. A further appliance combination comprises two cooking appliances and at least three downdraft extractors. In this case, two extraction units are arranged adjacent to each cooking appliance, and one extraction unit is located between the two cooking appliances. However, it is also within the scope of the invention for other combinations of cooking appliances and extraction units to be included in the appliance combination.In particular, the number of cooking appliances and extractor hoods may differ from the numbers mentioned. Preferably, however, each cooking appliance is assigned at least one extractor hood, and more preferably at least two extractor hoods. An extractor hood is defined as one that is arranged in such a way that it can extract at least some of the fumes and vapors produced by cooking on the respective cooking appliance.

[0030] According to a further aspect, the present invention relates to a method for operating at least one extractor hood of a device combination according to the invention. The method is characterized in that an operating state of at least one of the at least one cooking appliance is detected and, based on this operating state, at least one extractor hood is controlled.

[0031] The operating state of the cooking appliance refers, firstly, to the activation and / or deactivation of at least one part of the cooking appliance, for example, a cooking zone. Secondly, the operating state of the cooking appliance that is detected preferably also includes the power level of at least one part of the cooking appliance, for example, a cooking zone. By detecting the operating state of at least one cooking appliance, the control of at least one extractor fan can be selectively determined according to the current conditions. For example, when the cooking appliance is switched on, the extractor fan can automatically be put into a fully automatic operating mode. If the power setting in at least one cooking area, for example, a cooking zone, is also detected as an operating state of the cooking appliance, the extractor fan can then be put into an operating mode in which the fan speed is set to a predefined value.

[0032] By controlling the extractor fan based on the detected operating status of the cooking appliance, the extractor fan can be adjusted according to the prevailing or expected conditions.

[0033] According to the invention, controlling the extractor fan can include selecting the extractor fan. Since at least two extractor fans are provided according to the invention, when an operating state of a cooking appliance is detected, for example, the extractor fan adjacent to that cooking appliance can be selected and controlled. Furthermore, controlling the extractor fan preferably includes activating and / or deactivating at least one extractor fan. Activating the extractor fan can mean switching it on. Deactivating it can mean switching it off. Additionally, controlling the extractor fan includes setting an operating mode. The operating mode can, for example, be a fully automatic mode. In this mode, the extractor fan is activated in such a way that manual input by the user is no longer necessary.Alternatively, the operating mode can also include setting a fan speed on the extractor hood. Finally, calling up a program, such as a run-on ventilation cycle, can also constitute setting an operating mode.

[0034] According to one embodiment, at least one sensor signal is acquired, and the extractor fan is also controlled based on this sensor signal. The sensor signal is therefore used in the algorithm for controlling at least one extractor fan, in addition to the detected operating state of the cooking appliance. The sensor signal is particularly preferably used to select an operating mode setting for the extractor fan. For example, by adjusting the fan speed based on the sensor signal from an air quality sensor, a reliable setting of the desired air quality can be ensured.

[0035] According to a preferred embodiment, the operating state of the cooking appliance that is detected includes the position and preferably also the power level of a cooking zone of the cooking appliance. Cooking appliances, such as cooktops, generally have several cooking zones, each of which can be used to heat food in a cooking vessel. If the method according to the invention detects that a cooking zone, located, for example, in the left area of ​​the cooking appliance, has been set to a power level, this detection of the operating state can be used to select a suitable extraction device. In particular, for example, a downdraft ventilation system adjacent to the left side of the cooking appliance can be controlled.

[0036] According to one embodiment of the inventive method, before the operating state of the cooking appliance is detected, the number, type, and position of the cooking appliances, the number, type, and position of the extractor hoods, and optionally the number and position of the cooking zones of each cooking appliance in the appliance combination are stored. This information can be stored in the processing unit in which the algorithm for controlling the extractor hood is stored, or in a storage unit connected to this processing unit.

[0037] According to one embodiment, at least one cooking appliance in the appliance combination is treated as the master and the at least one extractor hood as the slave in the algorithm. This embodiment can be used, for example, for simple appliance combinations with only one cooking appliance and two extractor hoods.

[0038] According to a preferred embodiment, the method according to the invention is carried out fully automatically.

[0039] According to a further aspect, the present invention relates to a computer program product that causes the execution of the method according to the second aspect in a device combination according to the first aspect of the invention. The computer program product is preferably stored in a processing unit of the device combination and comprises program code means configured to execute the method according to the invention, wherein the computer program product can run on the processing unit or be stored on a computer-readable data carrier. The processing unit can, in particular, comprise a programmable microcomputer or microcontroller. Advantages and features described with respect to the device combination according to the invention also apply—to the extent applicable—to the method according to the invention and the computer program product, and vice versa.

[0040] The present invention will now be explained again with reference to the accompanying drawings. These show: Figure 1 : a schematic block diagram of a first embodiment of the device combination according to the invention; and Figure 2 : a schematic block representation of a second embodiment of the device combination according to the invention.

[0041] In Figure 1A first embodiment of a device combination 1 according to the invention is shown schematically in block diagram form. In this embodiment, the device combination 1 comprises three extractor hoods 12, 13, 14, and two cooking appliances, namely a cooktop 10 and a grill 11, which is a tappan-yaki grill. The extractor hoods 12, 13, 14 are downdraft extractors. In the embodiment shown, the cooktop 10 has four cooking zones 100, 101, 102, 103. The extractor hoods 12, 13, 14 are arranged laterally adjacent to the cooktop 10 and the grill 11, so that the central extractor hood 13 is located between the cooktop 10 and the grill 11.

[0042] Each of the devices 10, 11, 12, 13, 14 of the device combination 1 has a 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, be printed circuit boards (PCBs). The communication modules 20, 21, 22 are connected to or integrated into the respective processing unit 23, 24, 25 of the respective device 10, 11, 12, 13, 14.

[0043] In the illustrated embodiment, in addition to the devices 10, 11, 12, 13, 14 of the device combination 1, a separate communication device 2 is provided. The communication device 2 comprises a communication module 26 and a processing unit 27. The communication module 26 is connected to or integrated into the processing unit 27.

[0044] Furthermore, a sensor 3 is shown, which preferably represents an air quality sensor. The sensor 3 can be integrated into one of the devices of the device combination 1 or be installed separately from the device combination 1 in the room. It is also possible that more than one sensor 3 is provided. The sensor 3 is designed to transmit sensor signals to the processing unit 27 of the communication device 2.

[0045] In the embodiment shown, the algorithm for executing the method of operating at least one of the extractor hoods 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 an associated storage unit (not shown).

[0046] Before the algorithm is used 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. Specifically, the type and number of devices 10, 11, 12, 13, 14, their relative positions, and the number of cooking zones 100, 101, 102, 103 of the cooktop 10 and their positions within the cooktop 10 are stored in the processing unit 27. This can be done via a user interface (not shown). In addition to this information, information about the communication modules 20, 21, 22 of the respective devices 10, 11, 12, 13, 14 is preferably also stored. This information could, for example, be the addresses of the communication modules in a communication network, such as a WLAN (wireless local area network).

[0047] The algorithm can be executed with this information.

[0048] For example, if cooking zone 103 of the cooktop 10 is activated, this can be detected by the processing unit 27 through corresponding signals received via the communication modules 21 and 26. According to the algorithm and the stored information, the extractor hood 13 is identified as the extractor hood closest to the activated cooking zone 103. The extractor hood 13 is therefore activated. Activation can mean switching on the extractor hood 13 and operating it at a predefined fan speed. If the sensor 3 detects that the air quality still does not meet the stored values, the processing unit 27 can transmit a further control signal to the extractor hood 13, thereby increasing its fan speed.

[0049] If, however, it is detected that, for example, grill 11 has been activated, the adjacent extractor hoods 13 and 14 can be activated. After activation, the sensor signals for these hoods can also be processed to determine whether the fan speed needs to be increased. This increase in the fan speed of extractor hoods 13 and 14 can again be achieved via control signals generated by the processing unit 27 of the communication device 2, based on the stored algorithm.

[0050] 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, which can take place via WLAN.

[0051] The communication device 2 can also be referred to as a communication box and is particularly advantageous in more complex configurations, such as the combination of two cooking appliances 10, 11 and three extractor hoods 12, 13, 14 shown in the first embodiment. The communication box can be integrated into one of the appliances 10, 11, 12, 13, 14, for example, one of the cooking appliances 10, 11, or be designed separately from them. Before initial operation, the user preferably configures the communication box. This involves informing the communication box which types of appliances 10, 11, 12, 13, 14 are connected and their positions in the configuration. Subsequently, all appliances 10, 11, 12, 13, 14 communicate via the communication device 2, i.e., via the communication box.The performance of each cooking appliance 10, 11 or the cooking zones 100, 101, 102, 103 and the feedback from the air quality sensor 3 when controlling the extractor hood(s) 12, 13, 14 are taken into account.

[0052] In the Figure 2 A second embodiment of the device combination 1 according to the invention is shown.

[0053] In this embodiment, the appliance combination 1 consists of a cooktop 10 with four cooking zones 100, 101, 102, 103 and two downdraft extractors 12, 13, which are arranged laterally adjacent to the cooktop 10. A sensor 3 is also provided in this embodiment. The cooktop 10 has a processing unit 24 and a communication module 21. The communication module 21 can be integrated into or connected to the processing unit 24. The downdraft extractors 12, 13 each have a processing unit 23 and a communication module 20. Here, too, the communication module 20 can be integrated into or connected to the processing unit 24.

[0054] In the second embodiment, the algorithm for operating at least one extractor fan 12, 13 is preferably stored in the processing unit 24 of the cooktop 10. The algorithm can be stored on a control board, for example, in a microprocessor. The algorithm specifies, for example, that when the activation of one or both of the right-hand cooking zones 101, 103 is detected, the right-hand extractor fan 13 is activated. When the activation of one or both of the left-hand cooking zones 100, 102 is detected, the left-hand extractor fan 12 is activated. The cooktop 10 with its cooking zones 100, 101, 102, 103 is treated as the master, and the extractor fans 12, 13 as slaves.

[0055] In this embodiment, the communication modules 20, 21 can communicate, for example, via a local network such as WLAN. An application can be integrated into the WLAN network.

[0056] In the second embodiment, if it is detected that a cooking zone 100, 101, 102, 103 or several cooking zones 100, 101, 102, 103 are activated, one or both extractor hoods 12, 13 are selected based on the algorithm stored in the processing unit 24 of the cooktop 10 and a corresponding control signal is transmitted to the extractor hood(s) 12, 13.

[0057] For the processing of 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.

[0058] In the second embodiment, a four-zone cooktop 10 is combined with two laterally arranged extractor hoods 12, 13, which can also be referred to as downdraft systems. Each extractor hood 12, 13 has its own fan, allowing them to be operated independently. If the user uses only one of the cooking zones 100, 101, 102, 103, for example, on the left side, only the extractor hood 12 located to the left of the cooktop 10 is operated. The extractor hoods 12, 13 are thus operated automatically based on the number of cooking zones 100, 101, 102, 103 that are switched on, their power output, and preferably the information from the air quality sensor 3. The information from the air quality sensor 3 is preferably used only to set a fan speed but not to activate the extractor hoods 12, 13.

[0059] Furthermore, the device combination according to the invention can, for example, combine a four-zone induction or gas cooktop with a range hood having at least two extraction units. The range hood can be, in particular, an island hood or a wall-mounted range hood, in which fans are provided as extraction units. The width of the extraction unit is freely selectable. The extraction units of the range hood preferably remain in fully automatic mode at all times. When the user switches on the cooktop, in particular the induction cooktop, at least one of the fans controlled by the induction cooktop is automatically started. The range hood can be completely controlled by the algorithm.This algorithm takes into account not only how many cooking zones are activated, the power output of each zone, and their position, but also information from the air quality sensor. The more cooking zones are activated, the higher the power output, or the greater the amount of cooking fumes, the higher the airflow rate. When the user finishes cooking and switches off the cooking zones, the fan(s) automatically slow down and stop. In this configuration of the appliance combination, which uses only one cooktop and a range hood with two extraction units, the algorithm can be integrated, for example, on a control board in one of the appliances. The appliances can then communicate with each other via a communication module provided on the appliance, which allows communication with programs or apps that may be installed on a mobile device.In this case, the cooking appliances are treated as masters and the extractor hoods as slaves in the algorithm.

[0060] The present invention offers several advantages. Whereas with conventional extractor hoods with sensors, the user must manually set the extractor hood to an automatic mode to ensure that the fan can be activated based on the sensor signals, the automatic mode setting in the present invention can be achieved by controlling the extractor hood via an algorithm that takes into account the operating state of a cooking appliance. The extractor hood is preferably controlled by the cooking appliance.

[0061] Therefore, in the device combination according to the invention, the extractor hood can also be described as a fully automatic device. The extractor hood can optionally be set to fully automatic mode once by the user, or it may be delivered in fully automatic mode. The cooking appliances and the extractor hoods are connected to each other in such a way that the cooking appliance(s) are able to control the extractor hood(s).

[0062] Furthermore, the present invention allows the use of extractor hoods, each with its own fan. Each fan is preferably driven by a brushless DC motor and can have an input voltage of 0 to 10 volts. This allows the fans to be managed and controlled by an electronic board, in particular a printed circuit board (PCB).

[0063] Furthermore, in the present invention, one or more sensors can be integrated into the devices so that they can communicate with each other or at least with a central control system.

[0064] The user can now concentrate on the cooking process. Ventilation, and in particular the extraction of steam and fumes, is handled automatically by the appliances and no longer by the user.

[0065] Thanks to the present invention, the extractor hoods become smart devices that are fully controlled by the cooking appliances depending on their use by the user. Reference sign
