Universal device for the automation of solid fuel barbecues and ovens

Abstract

A universal device for the automation of solid fuel barbecues and ovens is provided that includes an automated draft butterfly-type valve housed in a chimney module. The chimney module can be installed at the smoke exhaust of the oven or barbecue over which control is intended. An electronic board is housed in a control module linked to a motor. The motor rotates the butterfly-type valve that in turn drives the exit of the gas flow via an exit signal that supplies the butterfly-type valve. The electronic board is in connection with at least a room temperature probe located within the chamber of the oven or barbecue. The control module has a control means and a power supply. A solid fuel barbeque can be fitted with the universal device.
