- the sensor data are evaluated in the control unit and, if there is a deviation from a preset desirable state, a corresponding adjustment is made by signals to one or more actuating components until the sensor data are again in the desirable range. Optimized operation of the exhaust air hood is achieved in this way.
- the actuating component is preferably formed by a fan, a regulating flap and / or a heating device.
- the exhaust air flow can be increased, diverted, returned and / or heated using appropriate control components.
- the one or more actuating components are adjusted in this way by the control unit controlled that a value measured by the sensor remains in a desirable range or is fed back into this range.
- the sensor, actuating component and control unit form a control circuit for the exhaust air hood.
- the communication interface is preferably set up for wireless data transmission, preferably via WLAN, Bluetooth, ZigBee or infrared.
- wireless data transmission preferably via WLAN, Bluetooth, ZigBee or infrared.
- the communication interface can have a local connection for temporary wired data transmission, preferably a USB cable.
- the exhaust air hood can be operated without cabling as standard.
- a connection to the exhaust hood can be established temporarily via wired data transmission and, for example, status data can be read out or control commands can be transferred to the exhaust hood.
- an exhaust air hood system comprising at least one, preferably a plurality of exhaust air hoods.
- the exhaust hood system also includes at least one mobile user unit, each of which has at least one exhaust hood via the communication interface of the control unit. is bindable and which is set up for data transmission from the control unit and / or to the control unit.
- the exhaust hood system can be monitored, controlled, optimized and / or newly set up via such a mobile user unit.
- the use of a mobile user unit eliminates the need for permanent cabling of the individual exhaust air hoods to form an exhaust air hood system.
- the mobile user unit can preferably be temporarily connected to an exhaust air hood of the exhaust air hood system by means of a data transmission cable. Only temporary cabling is therefore necessary, for example via a USB cable, which can be disconnected after the data transfer, that is to say the reading of data and / or the feeding of data into the control unit.
- the mobile user unit of the exhaust air hood system can additionally or alternatively be connected by means of wireless data transmission with an exhaust air hood, a preferably selectable group of exhaust air hoods or all exhaust air hoods of the exhaust air hood system.
- the mobile user unit can then be used to retrieve and / or transfer data from an exhaust hood, a preferably selectable subgroup of exhaust hoods with which it is in communication connection, or all exhaust hoods of the exhaust hood system. It can thus be selected whether the user unit enters into a communication link with one or individually selected exhaust hoods of the exhaust hood system and / or whether the user unit transmits data from all exhaust hoods of the exhaust hood system with which it is in communication. reads or transfers data to them.
- the exhaust hoods of an exhaust hood system according to the invention can be monitored in a simple and user-friendly manner and, if necessary, set up for an optimized operation by transmitting new control commands to the respective control units of the exhaust hoods.
- the mobile user unit preferably has an output unit and / or an input unit. Information from the exhaust air hood system or individual exhaust air hoods can be output via this and / or commands to the exhaust air hood system or individual exhaust air hoods to the user of the exhaust air hood system can be transmitted by the user.
- the mobile user unit is preferably a smartphone, a tablet computer or a laptop, which may be set up using appropriate software for communication with individual exhaust hoods.
- the exhaust hood system preferably has a central display for error messages, with which all exhaust hoods of the exhaust hood system are in communication.
- the communication link to the central display for error messages can be wireless, but possibly also wired.
- the costs of installing wired communication with a display for error messages can be compensated for by the saved costs of an early central display of errors and the corresponding possibility of faster reaction and correction of the errors.
- a central display for error messages can be an independent system or, for example, when entering In the commercial kitchens of passenger ships, the system can be integrated into a ship-wide technical monitoring system with which a flight engineer can keep an eye on the status of all technical systems on board.
