Brief: I want my cooker hood to automatically turn on.
During the preparation of food, strong smells are often produced, which can embed in clothing, furniture and hair. Regardless of how good of a cook you are, this can be unpleasant. No surprise then, that cooker hoods or extractor fans are commonplace in kitchens and sometimes even form part of building regulations. Turning an extractor fan on is usually a manual affair when we venture into the kitchen and start to prepare dinner. But what if you had an automatic cooker hood? One with an extractor fan that knows when you are cooking and automatically turns on for you?
Sometimes, a ventilation system is installed instead of a cooker hood, which ensures that unpleasant smells can be removed. Regardless of how the air in the kitchen is extracted, let’s look at how you can activate the automatic cooker hood with an extractor fan or boost the ventilation system during cooking.
Solution: How to commission an automatic cooker hood with extractor fan.
With Loxone it is possible to detect cooking automatically and thus switch on the available ventilation or extraction devices without you having to do this. But how can an extractor fan know when to turn on when you start cooking? Well, we’re simply going to have the Loxone system monitor for when the hob is switched on. The easiest way to achieve this from a technical point of view is with current flow detection.
The Nano 2 Relay, essentially a decentralised relay, offers exactly this function. With the adjustable current flow detection, it is very easy to detect when the hob is switched on.
If the hob is in operation, then a form of ventilation is required, which is usually an extractor fan in the cooker hood. So the Loxone system will ensure the extractor fan is turned on or the alternate ventilation system can be set to boost. Now, when we are done cooking, that is not necessarily when the ventilation or extractor fan should stop. For this reason, we use a switch-off delay to ensure the automatic cooker hood continues to run for a specified amount of time after turning the hob off.

Automatic Extractor Fan
Why you and your customer should consider having an automatic cooker hood.
An automatic cooker hood with extractor fan or automatically enabling the boost feature on a room ventilation system ensures that unpleasant odour build-up is mitigated. Thanks to the automation, the extractor does not have to be activated manually – nor will it be left on in a moment of forgetfulness. If a ventilation system is used in your customer’s building to provide fresh air, the automatic boost saves them from having to actively intervene in the ventilation settings.
