Clothes dryer project part 3

I work on the dryer every now and then, and at present I am working on the chimney and the ‘chimney pot’ which is design to extract air passively by the Bernoulli effect. I have also removed the light and will add a secondary fan instead. This fan will move air around inside the cabinet. I am also going to add a power switch and a dry switch (to initiate a drying ‘cycle’). This second fan will push air down from just under the roof and I hope this will mean the humid air distribution will mean that the sensors will see a humidity rise and then the computer can be programmed to handle this humidity and turn of when it drops, which hopefully means the clothes are dry. A secondary benefit of the internal fan is to stop the bad smell which gets into the clothes because of the lack of air movement. It turns out I think that just sucking out the humid air up the chimney does not work to dry clothes, air must be required to flow past the clothing.
